+\fBnamed\-checkconf\fR [\fB\-hjvz\fR] [\fB\-p\fR\ [\fB\-x\fR\ ]] [\fB\-t\ \fR\fB\fIdirectory\fR\fR] {filename}
+.SH "DESCRIPTION"
+.PP
+\fBnamed\-checkconf\fR
+checks the syntax, but not the semantics, of a
+\fBnamed\fR
+configuration file\&. The file is parsed and checked for syntax errors, along with all files included by it\&. If no file is specified,
+/etc/named\&.conf
+is read by default\&.
+.PP
+Note: files that
+\fBnamed\fR
+reads in separate parser contexts, such as
+rndc\&.key
+and
+bind\&.keys, are not automatically read by
+\fBnamed\-checkconf\fR\&. Configuration errors in these files may cause
+\fBnamed\fR
+to fail to run, even if
+\fBnamed\-checkconf\fR
+was successful\&.
+\fBnamed\-checkconf\fR
+can be run on these files explicitly, however\&.
+.SH "OPTIONS"
+.PP
+\-h
+.RS 4
+Print the usage summary and exit\&.
+.RE
+.PP
+\-j
+.RS 4
+When loading a zonefile read the journal if it exists\&.
+.RE
+.PP
+\-p
+.RS 4
+Print out the
+named\&.conf
+and included files in canonical form if no errors were detected\&. See also the
+\fB\-x\fR
+option\&.
+.RE
+.PP
+\-t \fIdirectory\fR
+.RS 4
+Chroot to
+directory
+so that include directives in the configuration file are processed as if run by a similarly chrooted
+\fBnamed\fR\&.
+.RE
+.PP
+\-v
+.RS 4
+Print the version of the
+\fBnamed\-checkconf\fR
+program and exit\&.
+.RE
+.PP
+\-x
+.RS 4
+When printing the configuration files in canonical form, obscure shared secrets by replacing them with strings of question marks (\*(Aq?\*(Aq)\&. This allows the contents of
+named\&.conf
+and related files to be shared \(em for example, when submitting bug reports \(em without compromising private data\&. This option cannot be used without
+\fB\-p\fR\&.
+.RE
+.PP
+\-z
+.RS 4
+Perform a test load of all master zones found in
+named\&.conf\&.
+.RE
+.PP
+filename
+.RS 4
+The name of the configuration file to be checked\&. If not specified, it defaults to
+/etc/named\&.conf\&.
+.RE
+.SH "RETURN VALUES"
+.PP
+\fBnamed\-checkconf\fR
+returns an exit status of 1 if errors were detected and 0 otherwise\&.
+.SH "SEE ALSO"

+      checks the syntax, but not the semantics, of a
+      <command>named</command> configuration file.  The file is parsed
+      and checked for syntax errors, along with all files included by it.
+      If no file is specified, <filename>/etc/named.conf</filename> is read
+      by default.
+    </para>
+    <para>
+      Note: files that <command>named</command> reads in separate
+      parser contexts, such as <filename>rndc.key</filename> and
+      <filename>bind.keys</filename>, are not automatically read
+      by <command>named-checkconf</command>.  Configuration
+      errors in these files may cause <command>named</command> to
+      fail to run, even if <command>named-checkconf</command> was
+      successful.  <command>named-checkconf</command> can be run
+      on these files explicitly, however.

+
+    <p><span class="command"><strong>named-checkconf</strong></span>
+      checks the syntax, but not the semantics, of a
+      <span class="command"><strong>named</strong></span> configuration file.  The file is parsed
+      and checked for syntax errors, along with all files included by it.
+      If no file is specified, <code class="filename">/etc/named.conf</code> is read
+      by default.
+    </p>
+    <p>
+      Note: files that <span class="command"><strong>named</strong></span> reads in separate
+      parser contexts, such as <code class="filename">rndc.key</code> and
+      <code class="filename">bind.keys</code>, are not automatically read
+      by <span class="command"><strong>named-checkconf</strong></span>.  Configuration
+      errors in these files may cause <span class="command"><strong>named</strong></span> to

+      successful.  <span class="command"><strong>named-checkconf</strong></span> can be run

+.SH "DESCRIPTION"
+.PP
+\fBnamed\-checkzone\fR
+checks the syntax and integrity of a zone file\&. It performs the same checks as
+\fBnamed\fR
+does when loading a zone\&. This makes
+\fBnamed\-checkzone\fR
+useful for checking zone files before configuring them into a name server\&.
+.PP
+\fBnamed\-compilezone\fR
+is similar to
+\fBnamed\-checkzone\fR, but it always dumps the zone contents to a specified file in a specified format\&. Additionally, it applies stricter check levels by default, since the dump output will be used as an actual zone file loaded by
+\fBnamed\fR\&. When manually specified otherwise, the check levels must at least be as strict as those specified in the
+\fBnamed\fR
+configuration file\&.
+.SH "OPTIONS"
+.PP
+\-d
+.RS 4
+Enable debugging\&.
+.RE
+.PP
+\-h
+.RS 4
+Print the usage summary and exit\&.
+.RE
+.PP
+\-q
+.RS 4
+Quiet mode \- exit code only\&.
+.RE
+.PP
+\-v
+.RS 4
+Print the version of the
+\fBnamed\-checkzone\fR
+program and exit\&.
+.RE
+.PP
+\-j
+.RS 4
+When loading a zone file, read the journal if it exists\&. The journal file name is assumed to be the zone file name appended with the string
+\&.jnl\&.
+.RE
+.PP
+\-J \fIfilename\fR
+.RS 4
+When loading the zone file read the journal from the given file, if it exists\&. (Implies \-j\&.)
+.RE
+.PP
+\-c \fIclass\fR
+.RS 4
+Specify the class of the zone\&. If not specified, "IN" is assumed\&.
+.RE
+.PP
+\-i \fImode\fR
+.RS 4
+Perform post\-load zone integrity checks\&. Possible modes are
+\fB"full"\fR
+(default),
+\fB"full\-sibling"\fR,
+\fB"local"\fR,
+\fB"local\-sibling"\fR
+and
+\fB"none"\fR\&.
+.sp
+Mode
+\fB"full"\fR
+checks that MX records refer to A or AAAA record (both in\-zone and out\-of\-zone hostnames)\&. Mode
+\fB"local"\fR
+only checks MX records which refer to in\-zone hostnames\&.
+.sp
+Mode
+\fB"full"\fR
+checks that SRV records refer to A or AAAA record (both in\-zone and out\-of\-zone hostnames)\&. Mode
+\fB"local"\fR
+only checks SRV records which refer to in\-zone hostnames\&.
+.sp
+Mode
+\fB"full"\fR
+checks that delegation NS records refer to A or AAAA record (both in\-zone and out\-of\-zone hostnames)\&. It also checks that glue address records in the zone match those advertised by the child\&. Mode
+\fB"local"\fR
+only checks NS records which refer to in\-zone hostnames or that some required glue exists, that is when the nameserver is in a child zone\&.
+.sp
+Mode
+\fB"full\-sibling"\fR
+and
+\fB"local\-sibling"\fR
+disable sibling glue checks but are otherwise the same as
+\fB"full"\fR
+and
+\fB"local"\fR
+respectively\&.
+.sp
+Mode
+\fB"none"\fR
+disables the checks\&.
+.RE
+.PP
+\-f \fIformat\fR
+.RS 4
+Specify the format of the zone file\&. Possible formats are
+\fB"text"\fR
+(default),
+\fB"raw"\fR, and
+\fB"map"\fR\&.
+.RE
+.PP
+\-F \fIformat\fR
+.RS 4
+Specify the format of the output file specified\&. For
+\fBnamed\-checkzone\fR, this does not cause any effects unless it dumps the zone contents\&.
+.sp
+Possible formats are
+\fB"text"\fR
+(default), which is the standard textual representation of the zone, and
+\fB"map"\fR,
+\fB"raw"\fR, and
+\fB"raw=N"\fR, which store the zone in a binary format for rapid loading by
+\fBnamed\fR\&.
+\fB"raw=N"\fR
+specifies the format version of the raw zone file: if N is 0, the raw file can be read by any version of
+\fBnamed\fR; if N is 1, the file can be read by release 9\&.9\&.0 or higher; the default is 1\&.
+.RE
+.PP
+\-k \fImode\fR
+.RS 4
+Perform
+\fB"check\-names"\fR
+checks with the specified failure mode\&. Possible modes are
+\fB"fail"\fR
+(default for
+\fBnamed\-compilezone\fR),
+\fB"warn"\fR
+(default for
+\fBnamed\-checkzone\fR) and
+\fB"ignore"\fR\&.
+.RE
+.PP
+\-l \fIttl\fR
+.RS 4
+Sets a maximum permissible TTL for the input file\&. Any record with a TTL higher than this value will cause the zone to be rejected\&. This is similar to using the
+\fBmax\-zone\-ttl\fR
+option in
+named\&.conf\&.
+.RE
+.PP
+\-L \fIserial\fR
+.RS 4
+When compiling a zone to "raw" or "map" format, set the "source serial" value in the header to the specified serial number\&. (This is expected to be used primarily for testing purposes\&.)
+.RE
+.PP
+\-m \fImode\fR
+.RS 4
+Specify whether MX records should be checked to see if they are addresses\&. Possible modes are
+\fB"fail"\fR,
+\fB"warn"\fR
+(default) and
+\fB"ignore"\fR\&.
+.RE
+.PP
+\-M \fImode\fR
+.RS 4
+Check if a MX record refers to a CNAME\&. Possible modes are
+\fB"fail"\fR,
+\fB"warn"\fR
+(default) and
+\fB"ignore"\fR\&.
+.RE
+.PP
+\-n \fImode\fR
+.RS 4
+Specify whether NS records should be checked to see if they are addresses\&. Possible modes are
+\fB"fail"\fR
+(default for
+\fBnamed\-compilezone\fR),
+\fB"warn"\fR
+(default for
+\fBnamed\-checkzone\fR) and
+\fB"ignore"\fR\&.
+.RE
+.PP
+\-o \fIfilename\fR
+.RS 4
+Write zone output to
+filename\&. If
+filename
+is
+\-
+then write to standard out\&. This is mandatory for
+\fBnamed\-compilezone\fR\&.
+.RE
+.PP
+\-r \fImode\fR
+.RS 4
+Check for records that are treated as different by DNSSEC but are semantically equal in plain DNS\&. Possible modes are
+\fB"fail"\fR,
+\fB"warn"\fR
+(default) and
+\fB"ignore"\fR\&.
+.RE
+.PP
+\-s \fIstyle\fR
+.RS 4
+Specify the style of the dumped zone file\&. Possible styles are
+\fB"full"\fR
+(default) and
+\fB"relative"\fR\&. The full format is most suitable for processing automatically by a separate script\&. On the other hand, the relative format is more human\-readable and is thus suitable for editing by hand\&. For
+\fBnamed\-checkzone\fR
+this does not cause any effects unless it dumps the zone contents\&. It also does not have any meaning if the output format is not text\&.
+.RE
+.PP
+\-S \fImode\fR
+.RS 4
+Check if a SRV record refers to a CNAME\&. Possible modes are
+\fB"fail"\fR,
+\fB"warn"\fR
+(default) and
+\fB"ignore"\fR\&.
+.RE
+.PP
+\-t \fIdirectory\fR
+.RS 4
+Chroot to
+directory
+so that include directives in the configuration file are processed as if run by a similarly chrooted
+\fBnamed\fR\&.
+.RE
+.PP
+\-T \fImode\fR
+.RS 4
+Check if Sender Policy Framework (SPF) records exist and issues a warning if an SPF\-formatted TXT record is not also present\&. Possible modes are
+\fB"warn"\fR
+(default),
+\fB"ignore"\fR\&.
+.RE
+.PP
+\-w \fIdirectory\fR
+.RS 4
+chdir to
+directory
+so that relative filenames in master file $INCLUDE directives work\&. This is similar to the directory clause in
+named\&.conf\&.
+.RE
+.PP
+\-D
+.RS 4
+Dump zone file in canonical format\&. This is always enabled for
+\fBnamed\-compilezone\fR\&.
+.RE
+.PP
+\-W \fImode\fR
+.RS 4
+Specify whether to check for non\-terminal wildcards\&. Non\-terminal wildcards are almost always the result of a failure to understand the wildcard matching algorithm (RFC 1034)\&. Possible modes are
+\fB"warn"\fR
+(default) and
+\fB"ignore"\fR\&.
+.RE
+.PP
+zonename

+    <para><command>named-checkzone</command>
+      checks the syntax and integrity of a zone file.  It performs the
+      same checks as <command>named</command> does when loading a
+      zone.  This makes <command>named-checkzone</command> useful for
+      checking zone files before configuring them into a name server.
+    </para>
+    <para>
+        <command>named-compilezone</command> is similar to
+	<command>named-checkzone</command>, but it always dumps the
+        zone contents to a specified file in a specified format.
+	Additionally, it applies stricter check levels by default,
+        since the dump output will be used as an actual zone file
+	loaded by <command>named</command>.
+	When manually specified otherwise, the check levels must at
+        least be as strict as those specified in the
+	<command>named</command> configuration file.

+
+    <p><span class="command"><strong>named-checkzone</strong></span>
+      checks the syntax and integrity of a zone file.  It performs the
+      same checks as <span class="command"><strong>named</strong></span> does when loading a
+      zone.  This makes <span class="command"><strong>named-checkzone</strong></span> useful for
+      checking zone files before configuring them into a name server.
+    </p>
+    <p>
+        <span class="command"><strong>named-compilezone</strong></span> is similar to
+	<span class="command"><strong>named-checkzone</strong></span>, but it always dumps the
+        zone contents to a specified file in a specified format.
+	Additionally, it applies stricter check levels by default,
+        since the dump output will be used as an actual zone file
+	loaded by <span class="command"><strong>named</strong></span>.
+	When manually specified otherwise, the check levels must at
+        least be as strict as those specified in the
+	<span class="command"><strong>named</strong></span> configuration file.

+.SH "NAME"
+ddns-confgen \- ddns key generation tool
+.SH "SYNOPSIS"
+.HP \w'\fBtsig\-keygen\fR\ 'u
+\fBtsig\-keygen\fR [\fB\-a\ \fR\fB\fIalgorithm\fR\fR] [\fB\-h\fR] [\fB\-r\ \fR\fB\fIrandomfile\fR\fR] [name]
+.HP \w'\fBddns\-confgen\fR\ 'u
+\fBddns\-confgen\fR [\fB\-a\ \fR\fB\fIalgorithm\fR\fR] [\fB\-h\fR] [\fB\-k\ \fR\fB\fIkeyname\fR\fR] [\fB\-q\fR] [\fB\-r\ \fR\fB\fIrandomfile\fR\fR] [\-s\ \fIname\fR | \-z\ \fIzone\fR]
+.SH "DESCRIPTION"
+.PP
+\fBtsig\-keygen\fR
+and
+\fBddns\-confgen\fR
+are invocation methods for a utility that generates keys for use in TSIG signing\&. The resulting keys can be used, for example, to secure dynamic DNS updates to a zone or for the
+\fBrndc\fR
+command channel\&.
+.PP
+When run as
+\fBtsig\-keygen\fR, a domain name can be specified on the command line which will be used as the name of the generated key\&. If no name is specified, the default is
+\fBtsig\-key\fR\&.
+.PP
+When run as
+\fBddns\-confgen\fR, the generated key is accompanied by configuration text and instructions that can be used with
+\fBnsupdate\fR
+and
+\fBnamed\fR
+when setting up dynamic DNS, including an example
+\fBupdate\-policy\fR
+statement\&. (This usage similar to the
+\fBrndc\-confgen\fR
+command for setting up command channel security\&.)
+.PP
+Note that
+\fBnamed\fR
+itself can configure a local DDNS key for use with
+\fBnsupdate \-l\fR: it does this when a zone is configured with
+\fBupdate\-policy local;\fR\&.
+\fBddns\-confgen\fR
+is only needed when a more elaborate configuration is required: for instance, if
+\fBnsupdate\fR
+is to be used from a remote system\&.
+.SH "OPTIONS"
+.PP
+\-a \fIalgorithm\fR
+.RS 4
+Specifies the algorithm to use for the TSIG key\&. Available choices are: hmac\-md5, hmac\-sha1, hmac\-sha224, hmac\-sha256, hmac\-sha384 and hmac\-sha512\&. The default is hmac\-sha256\&. Options are case\-insensitive, and the "hmac\-" prefix may be omitted\&.
+.RE
+.PP
+\-h
+.RS 4
+Prints a short summary of options and arguments\&.
+.RE
+.PP
+\-k \fIkeyname\fR
+.RS 4
+Specifies the key name of the DDNS authentication key\&. The default is
+\fBddns\-key\fR
+when neither the
+\fB\-s\fR
+nor
+\fB\-z\fR
+option is specified; otherwise, the default is
+\fBddns\-key\fR
+as a separate label followed by the argument of the option, e\&.g\&.,
+\fBddns\-key\&.example\&.com\&.\fR
+The key name must have the format of a valid domain name, consisting of letters, digits, hyphens and periods\&.
+.RE
+.PP
+\-q
+.RS 4
+(\fBddns\-confgen\fR
+only\&.) Quiet mode: Print only the key, with no explanatory text or usage examples; This is essentially identical to
+\fBtsig\-keygen\fR\&.
+.RE
+.PP
+\-r \fIrandomfile\fR
+.RS 4
+Specifies a source of random data for generating the authorization\&. If the operating system does not provide a
+/dev/random
+or equivalent device, the default source of randomness is keyboard input\&.
+randomdev
+specifies the name of a character device or file containing random data to be used instead of the default\&. The special value
+keyboard
+indicates that keyboard input should be used\&.
+.RE
+.PP
+\-s \fIname\fR
+.RS 4
+(\fBddns\-confgen\fR
+only\&.) Generate configuration example to allow dynamic updates of a single hostname\&. The example
+\fBnamed\&.conf\fR
+text shows how to set an update policy for the specified
+\fIname\fR
+using the "name" nametype\&. The default key name is ddns\-key\&.\fIname\fR\&. Note that the "self" nametype cannot be used, since the name to be updated may differ from the key name\&. This option cannot be used with the
+\fB\-z\fR
+option\&.
+.RE
+.PP
+\-z \fIzone\fR
+.RS 4
+(\fBddns\-confgen\fR
+only\&.) Generate configuration example to allow dynamic updates of a zone: The example
+\fBnamed\&.conf\fR
+text shows how to set an update policy for the specified
+\fIzone\fR
+using the "zonesub" nametype, allowing updates to all subdomain names within that
+\fIzone\fR\&. This option cannot be used with the
+\fB\-s\fR
+option\&.
+.RE
+.SH "SEE ALSO"
+.PP
+\fBnsupdate\fR(1),
+\fBnamed.conf\fR(5),
+\fBnamed\fR(8),

+.HP \w'\fBrndc\-confgen\fR\ 'u
+\fBrndc\-confgen\fR [\fB\-a\fR] [\fB\-A\ \fR\fB\fIalgorithm\fR\fR] [\fB\-b\ \fR\fB\fIkeysize\fR\fR] [\fB\-c\ \fR\fB\fIkeyfile\fR\fR] [\fB\-h\fR] [\fB\-k\ \fR\fB\fIkeyname\fR\fR] [\fB\-p\ \fR\fB\fIport\fR\fR] [\fB\-r\ \fR\fB\fIrandomfile\fR\fR] [\fB\-s\ \fR\fB\fIaddress\fR\fR] [\fB\-t\ \fR\fB\fIchrootdir\fR\fR] [\fB\-u\ \fR\fB\fIuser\fR\fR]
+.SH "DESCRIPTION"
+.PP
+\fBrndc\-confgen\fR
+generates configuration files for
+\fBrndc\fR\&. It can be used as a convenient alternative to writing the
+rndc\&.conf
+file and the corresponding
+\fBcontrols\fR
+and
+\fBkey\fR
+statements in
+named\&.conf
+by hand\&. Alternatively, it can be run with the
+\fB\-a\fR
+option to set up a
+rndc\&.key
+file and avoid the need for a
+rndc\&.conf
+file and a
+\fBcontrols\fR
+statement altogether\&.
+.SH "OPTIONS"
+.PP
+\-a
+.RS 4
+Do automatic
+\fBrndc\fR
+configuration\&. This creates a file
+rndc\&.key
+in
+/etc
+(or whatever
+\fIsysconfdir\fR
+was specified as when
+BIND
+was built) that is read by both
+\fBrndc\fR
+and
+\fBnamed\fR
+on startup\&. The
+rndc\&.key
+file defines a default command channel and authentication key allowing
+\fBrndc\fR
+to communicate with
+\fBnamed\fR
+on the local host with no further configuration\&.
+.sp
+Running
+\fBrndc\-confgen \-a\fR
+allows BIND 9 and
+\fBrndc\fR
+to be used as drop\-in replacements for BIND 8 and
+\fBndc\fR, with no changes to the existing BIND 8
+named\&.conf
+file\&.
+.sp
+If a more elaborate configuration than that generated by
+\fBrndc\-confgen \-a\fR
+is required, for example if rndc is to be used remotely, you should run
+\fBrndc\-confgen\fR
+without the
+\fB\-a\fR
+option and set up a
+rndc\&.conf
+and
+named\&.conf
+as directed\&.
+.RE
+.PP
+\-A \fIalgorithm\fR
+.RS 4
+Specifies the algorithm to use for the TSIG key\&. Available choices are: hmac\-md5, hmac\-sha1, hmac\-sha224, hmac\-sha256, hmac\-sha384 and hmac\-sha512\&. The default is hmac\-md5 or if MD5 was disabled hmac\-sha256\&.
+.RE
+.PP
+\-b \fIkeysize\fR
+.RS 4
+Specifies the size of the authentication key in bits\&. Must be between 1 and 512 bits; the default is the hash size\&.
+.RE
+.PP
+\-c \fIkeyfile\fR
+.RS 4
+Used with the
+\fB\-a\fR
+option to specify an alternate location for
+rndc\&.key\&.
+.RE
+.PP
+\-h
+.RS 4
+Prints a short summary of the options and arguments to
+\fBrndc\-confgen\fR\&.
+.RE
+.PP
+\-k \fIkeyname\fR
+.RS 4
+Specifies the key name of the rndc authentication key\&. This must be a valid domain name\&. The default is
+\fBrndc\-key\fR\&.
+.RE
+.PP
+\-p \fIport\fR
+.RS 4
+Specifies the command channel port where
+\fBnamed\fR
+listens for connections from
+\fBrndc\fR\&. The default is 953\&.
+.RE
+.PP
+\-r \fIrandomfile\fR
+.RS 4
+Specifies a source of random data for generating the authorization\&. If the operating system does not provide a
+/dev/random
+or equivalent device, the default source of randomness is keyboard input\&.
+randomdev
+specifies the name of a character device or file containing random data to be used instead of the default\&. The special value
+keyboard
+indicates that keyboard input should be used\&.
+.RE
+.PP
+\-s \fIaddress\fR
+.RS 4
+Specifies the IP address where
+\fBnamed\fR
+listens for command channel connections from
+\fBrndc\fR\&. The default is the loopback address 127\&.0\&.0\&.1\&.
+.RE
+.PP
+\-t \fIchrootdir\fR
+.RS 4
+Used with the
+\fB\-a\fR
+option to specify a directory where
+\fBnamed\fR
+will run chrooted\&. An additional copy of the
+rndc\&.key
+will be written relative to this directory so that it will be found by the chrooted
+\fBnamed\fR\&.
+.RE
+.PP
+\-u \fIuser\fR
+.RS 4
+Used with the
+\fB\-a\fR
+option to set the owner of the
+rndc\&.key
+file generated\&. If
+\fB\-t\fR
+is also specified only the file in the chroot area has its owner changed\&.
+.RE
+.SH "EXAMPLES"
+.PP
+To allow
+\fBrndc\fR
+to be used with no manual configuration, run
+.PP
+\fBrndc\-confgen \-a\fR
+.PP
+To print a sample
+rndc\&.conf
+file and corresponding
+\fBcontrols\fR
+and
+\fBkey\fR
+statements to be manually inserted into
+named\&.conf, run

+
+    <p><span class="command"><strong>rndc-confgen</strong></span>
+      generates configuration files
+      for <span class="command"><strong>rndc</strong></span>.  It can be used as a
+      convenient alternative to writing the
+      <code class="filename">rndc.conf</code> file
+      and the corresponding <span class="command"><strong>controls</strong></span>
+      and <span class="command"><strong>key</strong></span>
+      statements in <code class="filename">named.conf</code> by hand.
+      Alternatively, it can be run with the <span class="command"><strong>-a</strong></span>
+      option to set up a <code class="filename">rndc.key</code> file and
+      avoid the need for a <code class="filename">rndc.conf</code> file
+      and a <span class="command"><strong>controls</strong></span> statement altogether.
+    </p>

+<dd>
+          <p>
+            Do automatic <span class="command"><strong>rndc</strong></span> configuration.
+            This creates a file <code class="filename">rndc.key</code>
+            in <code class="filename">/etc</code> (or whatever
+            <code class="varname">sysconfdir</code>
+            was specified as when <acronym class="acronym">BIND</acronym> was
+            built)
+            that is read by both <span class="command"><strong>rndc</strong></span>
+            and <span class="command"><strong>named</strong></span> on startup.  The
+            <code class="filename">rndc.key</code> file defines a default
+            command channel and authentication key allowing
+            <span class="command"><strong>rndc</strong></span> to communicate with
+            <span class="command"><strong>named</strong></span> on the local host
+            with no further configuration.
+          </p>
+          <p>
+            Running <span class="command"><strong>rndc-confgen -a</strong></span> allows
+            BIND 9 and <span class="command"><strong>rndc</strong></span> to be used as
+            drop-in
+            replacements for BIND 8 and <span class="command"><strong>ndc</strong></span>,
+            with no changes to the existing BIND 8
+            <code class="filename">named.conf</code> file.
+          </p>
+          <p>
+            If a more elaborate configuration than that
+            generated by <span class="command"><strong>rndc-confgen -a</strong></span>
+            is required, for example if rndc is to be used remotely,
+            you should run <span class="command"><strong>rndc-confgen</strong></span> without
+            the
+            <span class="command"><strong>-a</strong></span> option and set up a

+.SH "DESCRIPTION"
+.PP
+\fBdelv\fR
+is a tool for sending DNS queries and validating the results, using the same internal resolver and validator logic as
+\fBnamed\fR\&.
+.PP
+\fBdelv\fR
+will send to a specified name server all queries needed to fetch and validate the requested data; this includes the original requested query, subsequent queries to follow CNAME or DNAME chains, and queries for DNSKEY, DS and DLV records to establish a chain of trust for DNSSEC validation\&. It does not perform iterative resolution, but simulates the behavior of a name server configured for DNSSEC validating and forwarding\&.
+.PP
+By default, responses are validated using built\-in DNSSEC trust anchor for the root zone ("\&.")\&. Records returned by
+\fBdelv\fR
+are either fully validated or were not signed\&. If validation fails, an explanation of the failure is included in the output; the validation process can be traced in detail\&. Because
+\fBdelv\fR
+does not rely on an external server to carry out validation, it can be used to check the validity of DNS responses in environments where local name servers may not be trustworthy\&.
+.PP
+Unless it is told to query a specific name server,
+\fBdelv\fR
+will try each of the servers listed in
+/etc/resolv\&.conf\&. If no usable server addresses are found,
+\fBdelv\fR
+will send queries to the localhost addresses (127\&.0\&.0\&.1 for IPv4, ::1 for IPv6)\&.
+.PP
+When no command line arguments or options are given,
+\fBdelv\fR
+will perform an NS query for "\&." (the root zone)\&.
+.SH "SIMPLE USAGE"
+.PP
+A typical invocation of
+\fBdelv\fR
+looks like:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+ delv @server name type 
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+where:
+.PP
+\fBserver\fR
+.RS 4
+is the name or IP address of the name server to query\&. This can be an IPv4 address in dotted\-decimal notation or an IPv6 address in colon\-delimited notation\&. When the supplied
+\fIserver\fR
+argument is a hostname,
+\fBdelv\fR
+resolves that name before querying that name server (note, however, that this initial lookup is
+\fInot\fR
+validated by DNSSEC)\&.
+.sp
+If no
+\fIserver\fR
+argument is provided,
+\fBdelv\fR
+consults
+/etc/resolv\&.conf; if an address is found there, it queries the name server at that address\&. If either of the
+\fB\-4\fR
+or
+\fB\-6\fR
+options are in use, then only addresses for the corresponding transport will be tried\&. If no usable addresses are found,
+\fBdelv\fR
+will send queries to the localhost addresses (127\&.0\&.0\&.1 for IPv4, ::1 for IPv6)\&.
+.RE
+.PP
+\fBname\fR
+.RS 4
+is the domain name to be looked up\&.
+.RE
+.PP
+\fBtype\fR
+.RS 4
+indicates what type of query is required \(em ANY, A, MX, etc\&.
+\fItype\fR
+can be any valid query type\&. If no
+\fItype\fR
+argument is supplied,
+\fBdelv\fR
+will perform a lookup for an A record\&.
+.RE
+.SH "OPTIONS"
+.PP
+\-a \fIanchor\-file\fR
+.RS 4
+Specifies a file from which to read DNSSEC trust anchors\&. The default is
+/etc/bind\&.keys, which is included with
+BIND
+9 and contains one or more trust anchors for the root zone ("\&.")\&.
+.sp
+Keys that do not match the root zone name are ignored\&. An alternate key name can be specified using the
+\fB+root=NAME\fR
+options\&. DNSSEC Lookaside Validation can also be turned on by using the
+\fB+dlv=NAME\fR
+to specify the name of a zone containing DLV records\&.
+.sp
+Note: When reading the trust anchor file,
+\fBdelv\fR
+treats
+\fBmanaged\-keys\fR
+statements and
+\fBtrusted\-keys\fR
+statements identically\&. That is, for a managed key, it is the
+\fIinitial\fR
+key that is trusted; RFC 5011 key management is not supported\&.
+\fBdelv\fR
+will not consult the managed\-keys database maintained by
+\fBnamed\fR\&. This means that if either of the keys in
+/etc/bind\&.keys
+is revoked and rolled over, it will be necessary to update
+/etc/bind\&.keys
+to use DNSSEC validation in
+\fBdelv\fR\&.
+.RE
+.PP
+\-b \fIaddress\fR
+.RS 4
+Sets the source IP address of the query to
+\fIaddress\fR\&. This must be a valid address on one of the host\*(Aqs network interfaces or "0\&.0\&.0\&.0" or "::"\&. An optional source port may be specified by appending "#<port>"
+.RE
+.PP
+\-c \fIclass\fR
+.RS 4
+Sets the query class for the requested data\&. Currently, only class "IN" is supported in
+\fBdelv\fR
+and any other value is ignored\&.
+.RE
+.PP
+\-d \fIlevel\fR
+.RS 4
+Set the systemwide debug level to
+\fBlevel\fR\&. The allowed range is from 0 to 99\&. The default is 0 (no debugging)\&. Debugging traces from
+\fBdelv\fR
+become more verbose as the debug level increases\&. See the
+\fB+mtrace\fR,
+\fB+rtrace\fR, and
+\fB+vtrace\fR
+options below for additional debugging details\&.
+.RE
+.PP
+\-h
+.RS 4
+Display the
+\fBdelv\fR
+help usage output and exit\&.
+.RE
+.PP
+\-i
+.RS 4
+Insecure mode\&. This disables internal DNSSEC validation\&. (Note, however, this does not set the CD bit on upstream queries\&. If the server being queried is performing DNSSEC validation, then it will not return invalid data; this can cause
+\fBdelv\fR
+to time out\&. When it is necessary to examine invalid data to debug a DNSSEC problem, use
+\fBdig +cd\fR\&.)
+.RE
+.PP
+\-m
+.RS 4
+Enables memory usage debugging\&.
+.RE
+.PP
+\-p \fIport#\fR
+.RS 4
+Specifies a destination port to use for queries instead of the standard DNS port number 53\&. This option would be used with a name server that has been configured to listen for queries on a non\-standard port number\&.
+.RE
+.PP
+\-q \fIname\fR
+.RS 4
+Sets the query name to
+\fIname\fR\&. While the query name can be specified without using the
+\fB\-q\fR, it is sometimes necessary to disambiguate names from types or classes (for example, when looking up the name "ns", which could be misinterpreted as the type NS, or "ch", which could be misinterpreted as class CH)\&.
+.RE
+.PP
+\-t \fItype\fR
+.RS 4
+Sets the query type to
+\fItype\fR, which can be any valid query type supported in BIND 9 except for zone transfer types AXFR and IXFR\&. As with
+\fB\-q\fR, this is useful to distinguish query name type or class when they are ambiguous\&. it is sometimes necessary to disambiguate names from types\&.
+.sp
+The default query type is "A", unless the
+\fB\-x\fR
+option is supplied to indicate a reverse lookup, in which case it is "PTR"\&.
+.RE
+.PP
+\-v
+.RS 4
+Print the
+\fBdelv\fR
+version and exit\&.
+.RE
+.PP
+\-x \fIaddr\fR
+.RS 4
+Performs a reverse lookup, mapping an addresses to a name\&.
+\fIaddr\fR
+is an IPv4 address in dotted\-decimal notation, or a colon\-delimited IPv6 address\&. When
+\fB\-x\fR
+is used, there is no need to provide the
+\fIname\fR
+or
+\fItype\fR
+arguments\&.
+\fBdelv\fR
+automatically performs a lookup for a name like
+11\&.12\&.13\&.10\&.in\-addr\&.arpa
+and sets the query type to PTR\&. IPv6 addresses are looked up using nibble format under the IP6\&.ARPA domain\&.
+.RE
+.PP
+\-4
+.RS 4
+Forces
+\fBdelv\fR
+to only use IPv4\&.
+.RE
+.PP
+\-6
+.RS 4
+Forces
+\fBdelv\fR
+to only use IPv6\&.
+.RE
+.SH "QUERY OPTIONS"
+.PP
+\fBdelv\fR
+provides a number of query options which affect the way results are displayed, and in some cases the way lookups are performed\&.
+.PP
+Each query option is identified by a keyword preceded by a plus sign (+)\&. Some keywords set or reset an option\&. These may be preceded by the string
+no
+to negate the meaning of that keyword\&. Other keywords assign values to options like the timeout interval\&. They have the form
+\fB+keyword=value\fR\&. The query options are:
+.PP
+\fB+[no]cdflag\fR
+.RS 4
+Controls whether to set the CD (checking disabled) bit in queries sent by
+\fBdelv\fR\&. This may be useful when troubleshooting DNSSEC problems from behind a validating resolver\&. A validating resolver will block invalid responses, making it difficult to retrieve them for analysis\&. Setting the CD flag on queries will cause the resolver to return invalid responses, which
+\fBdelv\fR
+can then validate internally and report the errors in detail\&.
+.RE
+.PP
+\fB+[no]class\fR
+.RS 4
+Controls whether to display the CLASS when printing a record\&. The default is to display the CLASS\&.
+.RE
+.PP
+\fB+[no]ttl\fR
+.RS 4
+Controls whether to display the TTL when printing a record\&. The default is to display the TTL\&.
+.RE
+.PP
+\fB+[no]rtrace\fR
+.RS 4
+Toggle resolver fetch logging\&. This reports the name and type of each query sent by
+\fBdelv\fR
+in the process of carrying out the resolution and validation process: this includes including the original query and all subsequent queries to follow CNAMEs and to establish a chain of trust for DNSSEC validation\&.
+.sp
+This is equivalent to setting the debug level to 1 in the "resolver" logging category\&. Setting the systemwide debug level to 1 using the
+\fB\-d\fR
+option will product the same output (but will affect other logging categories as well)\&.
+.RE
+.PP
+\fB+[no]mtrace\fR
+.RS 4
+Toggle message logging\&. This produces a detailed dump of the responses received by
+\fBdelv\fR
+in the process of carrying out the resolution and validation process\&.
+.sp
+This is equivalent to setting the debug level to 10 for the "packets" module of the "resolver" logging category\&. Setting the systemwide debug level to 10 using the
+\fB\-d\fR
+option will produce the same output (but will affect other logging categories as well)\&.
+.RE
+.PP
+\fB+[no]vtrace\fR
+.RS 4
+Toggle validation logging\&. This shows the internal process of the validator as it determines whether an answer is validly signed, unsigned, or invalid\&.
+.sp
+This is equivalent to setting the debug level to 3 for the "validator" module of the "dnssec" logging category\&. Setting the systemwide debug level to 3 using the
+\fB\-d\fR
+option will produce the same output (but will affect other logging categories as well)\&.
+.RE
+.PP
+\fB+[no]short\fR
+.RS 4
+Provide a terse answer\&. The default is to print the answer in a verbose form\&.
+.RE
+.PP
+\fB+[no]comments\fR
+.RS 4
+Toggle the display of comment lines in the output\&. The default is to print comments\&.
+.RE
+.PP
+\fB+[no]rrcomments\fR
+.RS 4
+Toggle the display of per\-record comments in the output (for example, human\-readable key information about DNSKEY records)\&. The default is to print per\-record comments\&.
+.RE
+.PP
+\fB+[no]crypto\fR
+.RS 4
+Toggle the display of cryptographic fields in DNSSEC records\&. The contents of these field are unnecessary to debug most DNSSEC validation failures and removing them makes it easier to see the common failures\&. The default is to display the fields\&. When omitted they are replaced by the string "[omitted]" or in the DNSKEY case the key id is displayed as the replacement, e\&.g\&. "[ key id = value ]"\&.
+.RE
+.PP
+\fB+[no]trust\fR
+.RS 4
+Controls whether to display the trust level when printing a record\&. The default is to display the trust level\&.
+.RE
+.PP
+\fB+[no]split[=W]\fR
+.RS 4
+Split long hex\- or base64\-formatted fields in resource records into chunks of
+\fIW\fR
+characters (where
+\fIW\fR
+is rounded up to the nearest multiple of 4)\&.
+\fI+nosplit\fR
+or
+\fI+split=0\fR
+causes fields not to be split at all\&. The default is 56 characters, or 44 characters when multiline mode is active\&.
+.RE
+.PP
+\fB+[no]all\fR
+.RS 4
+Set or clear the display options
+\fB+[no]comments\fR,
+\fB+[no]rrcomments\fR, and
+\fB+[no]trust\fR
+as a group\&.
+.RE
+.PP
+\fB+[no]multiline\fR
+.RS 4
+Print long records (such as RRSIG, DNSKEY, and SOA records) in a verbose multi\-line format with human\-readable comments\&. The default is to print each record on a single line, to facilitate machine parsing of the
+\fBdelv\fR
+output\&.
+.RE
+.PP
+\fB+[no]dnssec\fR
+.RS 4
+Indicates whether to display RRSIG records in the
+\fBdelv\fR
+output\&. The default is to do so\&. Note that (unlike in
+\fBdig\fR) this does
+\fInot\fR
+control whether to request DNSSEC records or whether to validate them\&. DNSSEC records are always requested, and validation will always occur unless suppressed by the use of
+\fB\-i\fR
+or
+\fB+noroot\fR
+and
+\fB+nodlv\fR\&.
+.RE
+.PP
+\fB+[no]root[=ROOT]\fR
+.RS 4
+Indicates whether to perform conventional (non\-lookaside) DNSSEC validation, and if so, specifies the name of a trust anchor\&. The default is to validate using a trust anchor of "\&." (the root zone), for which there is a built\-in key\&. If specifying a different trust anchor, then
+\fB\-a\fR
+must be used to specify a file containing the key\&.
+.RE
+.PP
+\fB+[no]dlv[=DLV]\fR
+.RS 4
+Indicates whether to perform DNSSEC lookaside validation, and if so, specifies the name of the DLV trust anchor\&. The
+\fB\-a\fR
+option must also be used to specify a file containing the DLV key\&.
+.RE
+.PP
+\fB+[no]tcp\fR
+.RS 4
+Controls whether to use TCP when sending queries\&. The default is to use UDP unless a truncated response has been received\&.
+.RE
+.PP
+\fB+[no]unknownformat\fR
+.RS 4
+Print all RDATA in unknown RR type presentation format (RFC 3597)\&. The default is to print RDATA for known types in the type\*(Aqs presentation format\&.

+
+    <para><command>delv</command>
+      is a tool for sending
+      DNS queries and validating the results, using the same internal
+      resolver and validator logic as <command>named</command>.
+    </para>
+    <para>
+      <command>delv</command> will send to a specified name server all
+      queries needed to fetch and validate the requested data; this
+      includes the original requested query, subsequent queries to follow
+      CNAME or DNAME chains, and queries for DNSKEY, DS and DLV records
+      to establish a chain of trust for DNSSEC validation.
+      It does not perform iterative resolution, but simulates the
+      behavior of a name server configured for DNSSEC validating and
+      forwarding.
+    </para>
+    <para>
+      By default, responses are validated using built-in DNSSEC trust
+      anchor for the root zone (".").  Records returned by
+      <command>delv</command> are either fully validated or
+      were not signed.  If validation fails, an explanation of
+      the failure is included in the output; the validation process
+      can be traced in detail.  Because <command>delv</command> does
+      not rely on an external server to carry out validation, it can
+      be used to check the validity of DNS responses in environments
+      where local name servers may not be trustworthy.
+    </para>
+    <para>
+      Unless it is told to query a specific name server,
+      <command>delv</command> will try each of the servers listed in
+      <filename>/etc/resolv.conf</filename>. If no usable server
+      addresses are found, <command>delv</command> will send
+      queries to the localhost addresses (127.0.0.1 for IPv4, ::1
+      for IPv6).
+    </para>
+    <para>
+      When no command line arguments or options are given,
+      <command>delv</command> will perform an NS query for "."
+      (the root zone).
+    </para>
+  </refsection>
+
+  <refsection><info><title>SIMPLE USAGE</title></info>
+
+
+    <para>
+      A typical invocation of <command>delv</command> looks like:
+      <programlisting> delv @server name type </programlisting>
+      where:
+
+      <variablelist>
+	<varlistentry>
+	  <term><constant>server</constant></term>
+	  <listitem>
+	    <para>
+	      is the name or IP address of the name server to query.  This
+	      can be an IPv4 address in dotted-decimal notation or an IPv6
+	      address in colon-delimited notation.  When the supplied
+	      <parameter>server</parameter> argument is a hostname,
+	      <command>delv</command> resolves that name before
+	      querying that name server (note, however, that this
+	      initial lookup is <emphasis>not</emphasis> validated
+	      by DNSSEC).
+	    </para>
+	    <para>
+	      If no <parameter>server</parameter> argument is
+	      provided, <command>delv</command> consults
+	      <filename>/etc/resolv.conf</filename>; if an
+	      address is found there, it queries the name server at
+	      that address. If either of the <option>-4</option> or
+	      <option>-6</option> options are in use, then
+	      only addresses for the corresponding transport
+	      will be tried.  If no usable addresses are found,
+	      <command>delv</command> will send queries to
+	      the localhost addresses (127.0.0.1 for IPv4,
+	      ::1 for IPv6).

+	      type.  If no

+
+      <varlistentry>
+	<term>-a <replaceable class="parameter">anchor-file</replaceable></term>
+	<listitem>
+	  <para>
+	    Specifies a file from which to read DNSSEC trust anchors.
+	    The default is <filename>/etc/bind.keys</filename>, which
+	    is included with <acronym>BIND</acronym> 9 and contains
+	    one or more trust anchors for the root zone (".").
+	  </para>
+	  <para>
+	    Keys that do not match the root zone name are ignored.
+            An alternate key name can be specified using the
+	    <option>+root=NAME</option> options. DNSSEC Lookaside
+            Validation can also be turned on by using the
+	    <option>+dlv=NAME</option> to specify the name of a
+            zone containing DLV records.
+	  </para>
+	  <para>
+	    Note: When reading the trust anchor file,
+	    <command>delv</command> treats <option>managed-keys</option>
+	    statements and <option>trusted-keys</option> statements
+	    identically.  That is, for a managed key, it is the
+	    <emphasis>initial</emphasis> key that is trusted; RFC 5011
+	    key management is not supported. <command>delv</command>
+	    will not consult the managed-keys database maintained by
+	    <command>named</command>. This means that if either of the
+	    keys in <filename>/etc/bind.keys</filename> is revoked
+	    and rolled over, it will be necessary to update
+	    <filename>/etc/bind.keys</filename> to use DNSSEC
+	    validation in <command>delv</command>.

+
+    <para><command>delv</command>
+      provides a number of query options which affect the way results are
+      displayed, and in some cases the way lookups are performed.
+    </para>
+
+    <para>
+      Each query option is identified by a keyword preceded by a plus sign
+      (<literal>+</literal>).  Some keywords set or reset an
+      option.  These may be preceded by the string
+      <literal>no</literal> to negate the meaning of that keyword.
+      Other keywords assign values to options like the timeout interval.
+      They have the form <option>+keyword=value</option>.
+      The query options are:
+
+      <variablelist>
+	<varlistentry>
+	  <term><option>+[no]cdflag</option></term>
+	  <listitem>
+	    <para>
+	      Controls whether to set the CD (checking disabled) bit in
+	      queries sent by <command>delv</command>. This may be useful
+	      when troubleshooting DNSSEC problems from behind a validating
+	      resolver. A validating resolver will block invalid responses,
+	      making it difficult to retrieve them for analysis. Setting
+	      the CD flag on queries will cause the resolver to return
+	      invalid responses, which <command>delv</command> can then
+	      validate internally and report the errors in detail.

+
+    <p><span class="command"><strong>delv</strong></span>
+      is a tool for sending
+      DNS queries and validating the results, using the same internal
+      resolver and validator logic as <span class="command"><strong>named</strong></span>.
+    </p>
+    <p>
+      <span class="command"><strong>delv</strong></span> will send to a specified name server all
+      queries needed to fetch and validate the requested data; this
+      includes the original requested query, subsequent queries to follow
+      CNAME or DNAME chains, and queries for DNSKEY, DS and DLV records
+      to establish a chain of trust for DNSSEC validation.
+      It does not perform iterative resolution, but simulates the
+      behavior of a name server configured for DNSSEC validating and
+      forwarding.
+    </p>
+    <p>
+      By default, responses are validated using built-in DNSSEC trust
+      anchor for the root zone (".").  Records returned by
+      <span class="command"><strong>delv</strong></span> are either fully validated or
+      were not signed.  If validation fails, an explanation of
+      the failure is included in the output; the validation process
+      can be traced in detail.  Because <span class="command"><strong>delv</strong></span> does
+      not rely on an external server to carry out validation, it can
+      be used to check the validity of DNS responses in environments
+      where local name servers may not be trustworthy.
+    </p>
+    <p>
+      Unless it is told to query a specific name server,
+      <span class="command"><strong>delv</strong></span> will try each of the servers listed in
+      <code class="filename">/etc/resolv.conf</code>. If no usable server
+      addresses are found, <span class="command"><strong>delv</strong></span> will send
+      queries to the localhost addresses (127.0.0.1 for IPv4, ::1
+      for IPv6).
+    </p>
+    <p>
+      When no command line arguments or options are given,
+      <span class="command"><strong>delv</strong></span> will perform an NS query for "."
+      (the root zone).
+    </p>
+  </div>
+
+  <div class="refsection">

+
+
+    <p>
+      A typical invocation of <span class="command"><strong>delv</strong></span> looks like:
+      </p>
+<pre class="programlisting"> delv @server name type </pre>
+<p>
+      where:
+
+      </p>
+<div class="variablelist"><dl class="variablelist">
+<dt><span class="term"><code class="constant">server</code></span></dt>
+<dd>
+	    <p>
+	      is the name or IP address of the name server to query.  This
+	      can be an IPv4 address in dotted-decimal notation or an IPv6
+	      address in colon-delimited notation.  When the supplied
+	      <em class="parameter"><code>server</code></em> argument is a hostname,
+	      <span class="command"><strong>delv</strong></span> resolves that name before
+	      querying that name server (note, however, that this
+	      initial lookup is <span class="emphasis"><em>not</em></span> validated
+	      by DNSSEC).
+	    </p>
+	    <p>
+	      If no <em class="parameter"><code>server</code></em> argument is
+	      provided, <span class="command"><strong>delv</strong></span> consults
+	      <code class="filename">/etc/resolv.conf</code>; if an
+	      address is found there, it queries the name server at
+	      that address. If either of the <code class="option">-4</code> or
+	      <code class="option">-6</code> options are in use, then
+	      only addresses for the corresponding transport
+	      will be tried.  If no usable addresses are found,
+	      <span class="command"><strong>delv</strong></span> will send queries to
+	      the localhost addresses (127.0.0.1 for IPv4,
+	      ::1 for IPv6).
+	    </p>
+	  </dd>
+<dt><span class="term"><code class="constant">name</code></span></dt>

+	      A record.

+	    The default is <code class="filename">/etc/bind.keys</code>, which
+	    is included with <acronym class="acronym">BIND</acronym> 9 and contains
+	    one or more trust anchors for the root zone (".").
+	  </p>
+	  <p>
+	    Keys that do not match the root zone name are ignored.
+            An alternate key name can be specified using the
+	    <code class="option">+root=NAME</code> options. DNSSEC Lookaside

+	  </p>
+	  <p>
+	    Note: When reading the trust anchor file,
+	    <span class="command"><strong>delv</strong></span> treats <code class="option">managed-keys</code>

+      option.  These may be preceded by the string
+      <code class="literal">no</code> to negate the meaning of that keyword.

+      They have the form <code class="option">+keyword=value</code>.

+.SH "DESCRIPTION"
+.PP
+\fBdig\fR
+is a flexible tool for interrogating DNS name servers\&. It performs DNS lookups and displays the answers that are returned from the name server(s) that were queried\&. Most DNS administrators use
+\fBdig\fR
+to troubleshoot DNS problems because of its flexibility, ease of use and clarity of output\&. Other lookup tools tend to have less functionality than
+\fBdig\fR\&.
+.PP
+Although
+\fBdig\fR
+is normally used with command\-line arguments, it also has a batch mode of operation for reading lookup requests from a file\&. A brief summary of its command\-line arguments and options is printed when the
+\fB\-h\fR
+option is given\&. Unlike earlier versions, the BIND 9 implementation of
+\fBdig\fR
+allows multiple lookups to be issued from the command line\&.
+.PP
+Unless it is told to query a specific name server,
+\fBdig\fR
+will try each of the servers listed in
+/etc/resolv\&.conf\&. If no usable server addresses are found,
+\fBdig\fR
+will send the query to the local host\&.
+.PP
+When no command line arguments or options are given,
+\fBdig\fR
+will perform an NS query for "\&." (the root)\&.
+.PP
+It is possible to set per\-user defaults for
+\fBdig\fR
+via
+${HOME}/\&.digrc\&. This file is read and any options in it are applied before the command line arguments\&.
+.PP
+The IN and CH class names overlap with the IN and CH top level domain names\&. Either use the
+\fB\-t\fR
+and
+\fB\-c\fR
+options to specify the type and class, use the
+\fB\-q\fR
+the specify the domain name, or use "IN\&." and "CH\&." when looking up these top level domains\&.
+.SH "SIMPLE USAGE"
+.PP
+A typical invocation of
+\fBdig\fR
+looks like:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+ dig @server name type 
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+where:
+.PP
+\fBserver\fR
+.RS 4
+is the name or IP address of the name server to query\&. This can be an IPv4 address in dotted\-decimal notation or an IPv6 address in colon\-delimited notation\&. When the supplied
+\fIserver\fR
+argument is a hostname,
+\fBdig\fR
+resolves that name before querying that name server\&.
+.sp
+If no
+\fIserver\fR
+argument is provided,
+\fBdig\fR
+consults
+/etc/resolv\&.conf; if an address is found there, it queries the name server at that address\&. If either of the
+\fB\-4\fR
+or
+\fB\-6\fR
+options are in use, then only addresses for the corresponding transport will be tried\&. If no usable addresses are found,
+\fBdig\fR
+will send the query to the local host\&. The reply from the name server that responds is displayed\&.
+.RE
+.PP
+\fBname\fR
+.RS 4
+is the name of the resource record that is to be looked up\&.
+.RE
+.PP
+\fBtype\fR
+.RS 4
+indicates what type of query is required \(em ANY, A, MX, SIG, etc\&.
+\fItype\fR
+can be any valid query type\&. If no
+\fItype\fR
+argument is supplied,
+\fBdig\fR
+will perform a lookup for an A record\&.
+.RE
+.SH "OPTIONS"
+.PP
+\-4
+.RS 4
+Use IPv4 only\&.
+.RE
+.PP
+\-6
+.RS 4
+Use IPv6 only\&.
+.RE
+.PP
+\-b \fIaddress\fR\fI[#port]\fR
+.RS 4
+Set the source IP address of the query\&. The
+\fIaddress\fR
+must be a valid address on one of the host\*(Aqs network interfaces, or "0\&.0\&.0\&.0" or "::"\&. An optional port may be specified by appending "#<port>"
+.RE
+.PP
+\-c \fIclass\fR
+.RS 4
+Set the query class\&. The default
+\fIclass\fR
+is IN; other classes are HS for Hesiod records or CH for Chaosnet records\&.
+.RE
+.PP
+\-f \fIfile\fR
+.RS 4
+Batch mode:
+\fBdig\fR
+reads a list of lookup requests to process from the given
+\fIfile\fR\&. Each line in the file should be organized in the same way they would be presented as queries to
+\fBdig\fR
+using the command\-line interface\&.
+.RE
+.PP
+\-i
+.RS 4
+Do reverse IPv6 lookups using the obsolete RFC 1886 IP6\&.INT domain, which is no longer in use\&. Obsolete bit string label queries (RFC 2874) are not attempted\&.
+.RE
+.PP
+\-k \fIkeyfile\fR
+.RS 4
+Sign queries using TSIG using a key read from the given file\&. Key files can be generated using
+\fBtsig-keygen\fR(8)\&. When using TSIG authentication with
+\fBdig\fR, the name server that is queried needs to know the key and algorithm that is being used\&. In BIND, this is done by providing appropriate
+\fBkey\fR
+and
+\fBserver\fR
+statements in
+named\&.conf\&.
+.RE
+.PP
+\-m
+.RS 4
+Enable memory usage debugging\&.
+.RE
+.PP
+\-p \fIport\fR
+.RS 4
+Send the query to a non\-standard port on the server, instead of the default port 53\&. This option would be used to test a name server that has been configured to listen for queries on a non\-standard port number\&.
+.RE
+.PP
+\-q \fIname\fR
+.RS 4
+The domain name to query\&. This is useful to distinguish the
+\fIname\fR
+from other arguments\&.
+.RE
+.PP
+\-t \fItype\fR
+.RS 4
+The resource record type to query\&. It can be any valid query type\&. If it is a resource record type supported in BIND 9, it can be given by the type mnemonic (such as "NS" or "AAAA")\&. The default query type is "A", unless the
+\fB\-x\fR
+option is supplied to indicate a reverse lookup\&. A zone transfer can be requested by specifying a type of AXFR\&. When an incremental zone transfer (IXFR) is required, set the
+\fItype\fR
+to
+ixfr=N\&. The incremental zone transfer will contain the changes made to the zone since the serial number in the zone\*(Aqs SOA record was
+\fIN\fR\&.
+.sp
+All resource record types can be expressed as "TYPEnn", where "nn" is the number of the type\&. If the resource record type is not supported in BIND 9, the result will be displayed as described in RFC 3597\&.
+.RE
+.PP
+\-u
+.RS 4
+Print query times in microseconds instead of milliseconds\&.
+.RE
+.PP
+\-v
+.RS 4
+Print the version number and exit\&.
+.RE
+.PP
+\-x \fIaddr\fR
+.RS 4
+Simplified reverse lookups, for mapping addresses to names\&. The
+\fIaddr\fR
+is an IPv4 address in dotted\-decimal notation, or a colon\-delimited IPv6 address\&. When the
+\fB\-x\fR
+is used, there is no need to provide the
+\fIname\fR,
+\fIclass\fR
+and
+\fItype\fR
+arguments\&.
+\fBdig\fR
+automatically performs a lookup for a name like
+94\&.2\&.0\&.192\&.in\-addr\&.arpa
+and sets the query type and class to PTR and IN respectively\&. IPv6 addresses are looked up using nibble format under the IP6\&.ARPA domain (but see also the
+\fB\-i\fR
+option)\&.
+.RE
+.PP
+\-y \fI[hmac:]\fR\fIkeyname:secret\fR
+.RS 4
+Sign queries using TSIG with the given authentication key\&.
+\fIkeyname\fR
+is the name of the key, and
+\fIsecret\fR
+is the base64 encoded shared secret\&.
+\fIhmac\fR
+is the name of the key algorithm; valid choices are
+hmac\-md5,
+hmac\-sha1,
+hmac\-sha224,
+hmac\-sha256,
+hmac\-sha384, or
+hmac\-sha512\&. If
+\fIhmac\fR
+is not specified, the default is
+hmac\-md5
+or if MD5 was disabled
+hmac\-sha256\&.
+.sp
+NOTE: You should use the
+\fB\-k\fR
+option and avoid the
+\fB\-y\fR
+option, because with
+\fB\-y\fR
+the shared secret is supplied as a command line argument in clear text\&. This may be visible in the output from
+\fBps\fR(1)
+or in a history file maintained by the user\*(Aqs shell\&.
+.RE
+.SH "QUERY OPTIONS"
+.PP
+\fBdig\fR
+provides a number of query options which affect the way in which lookups are made and the results displayed\&. Some of these set or reset flag bits in the query header, some determine which sections of the answer get printed, and others determine the timeout and retry strategies\&.
+.PP
+Each query option is identified by a keyword preceded by a plus sign (+)\&. Some keywords set or reset an option\&. These may be preceded by the string
+no
+to negate the meaning of that keyword\&. Other keywords assign values to options like the timeout interval\&. They have the form
+\fB+keyword=value\fR\&. Keywords may be abbreviated, provided the abbreviation is unambiguous; for example,
++cd
+is equivalent to
++cdflag\&. The query options are:
+.PP
+\fB+[no]aaflag\fR
+.RS 4
+A synonym for
+\fI+[no]aaonly\fR\&.
+.RE
+.PP
+\fB+[no]aaonly\fR
+.RS 4
+Sets the "aa" flag in the query\&.
+.RE
+.PP
+\fB+[no]additional\fR
+.RS 4
+Display [do not display] the additional section of a reply\&. The default is to display it\&.
+.RE
+.PP
+\fB+[no]adflag\fR
+.RS 4
+Set [do not set] the AD (authentic data) bit in the query\&. This requests the server to return whether all of the answer and authority sections have all been validated as secure according to the security policy of the server\&. AD=1 indicates that all records have been validated as secure and the answer is not from a OPT\-OUT range\&. AD=0 indicate that some part of the answer was insecure or not validated\&. This bit is set by default\&.
+.RE
+.PP
+\fB+[no]all\fR
+.RS 4
+Set or clear all display flags\&.
+.RE
+.PP
+\fB+[no]answer\fR
+.RS 4
+Display [do not display] the answer section of a reply\&. The default is to display it\&.
+.RE
+.PP
+\fB+[no]authority\fR
+.RS 4
+Display [do not display] the authority section of a reply\&. The default is to display it\&.

+.PP
+\fB+[no]badcookie\fR
+.RS 4
+Retry lookup with the new server cookie if a BADCOOKIE response is received\&.
+.RE
+.PP
+\fB+[no]besteffort\fR
+.RS 4
+Attempt to display the contents of messages which are malformed\&. The default is to not display malformed answers\&.
+.RE
+.PP
+\fB+bufsize=B\fR
+.RS 4
+Set the UDP message buffer size advertised using EDNS0 to
+\fIB\fR
+bytes\&. The maximum and minimum sizes of this buffer are 65535 and 0 respectively\&. Values outside this range are rounded up or down appropriately\&. Values other than zero will cause a EDNS query to be sent\&.
+.RE
+.PP
+\fB+[no]cdflag\fR
+.RS 4
+Set [do not set] the CD (checking disabled) bit in the query\&. This requests the server to not perform DNSSEC validation of responses\&.
+.RE
+.PP
+\fB+[no]class\fR
+.RS 4
+Display [do not display] the CLASS when printing the record\&.
+.RE
+.PP
+\fB+[no]cmd\fR
+.RS 4

+\fBdig\fR
+and the query options that have been applied\&. This comment is printed by default\&.
+.RE
+.PP
+\fB+[no]comments\fR
+.RS 4
+Toggle the display of comment lines in the output\&. The default is to print comments\&.
+.RE
+.PP
+\fB+[no]cookie\fR\fB[=####]\fR
+.RS 4
+Send a COOKIE EDNS option, with optional value\&. Replaying a COOKIE from a previous response will allow the server to identify a previous client\&. The default is
+\fB+cookie\fR\&.
+.sp
+\fB+cookie\fR
+is also set when +trace is set to better emulate the default queries from a nameserver\&.
+.RE
+.PP
+\fB+[no]crypto\fR
+.RS 4
+Toggle the display of cryptographic fields in DNSSEC records\&. The contents of these field are unnecessary to debug most DNSSEC validation failures and removing them makes it easier to see the common failures\&. The default is to display the fields\&. When omitted they are replaced by the string "[omitted]" or in the DNSKEY case the key id is displayed as the replacement, e\&.g\&. "[ key id = value ]"\&.
+.RE

+.SH "MULTIPLE QUERIES"
+.PP
+The BIND 9 implementation of
+\fBdig \fR
+supports specifying multiple queries on the command line (in addition to supporting the
+\fB\-f\fR
+batch file option)\&. Each of those queries can be supplied with its own set of flags, options and query options\&.
+.PP
+In this case, each
+\fIquery\fR
+argument represent an individual query in the command\-line syntax described above\&. Each consists of any of the standard options and flags, the name to be looked up, an optional query type and class and any query options that should be applied to that query\&.
+.PP
+A global set of query options, which should be applied to all queries, can also be supplied\&. These global query options must precede the first tuple of name, class, type, options, flags, and query options supplied on the command line\&. Any global query options (except the
+\fB+[no]cmd\fR
+option) can be overridden by a query\-specific set of query options\&. For example:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+dig +qr www\&.isc\&.org any \-x 127\&.0\&.0\&.1 isc\&.org ns +noqr
+.fi
+.if n \{\
+.RE
+.\}
+.sp
+shows how
+\fBdig\fR
+could be used from the command line to make three lookups: an ANY query for
+www\&.isc\&.org, a reverse lookup of 127\&.0\&.0\&.1 and a query for the NS records of
+isc\&.org\&. A global query option of
+\fI+qr\fR
+is applied, so that
+\fBdig\fR
+shows the initial query it made for each lookup\&. The final query has a local query option of
+\fI+noqr\fR
+which means that
+\fBdig\fR
+will not print the initial query when it looks up the NS records for
+isc\&.org\&.
+.SH "IDN SUPPORT"
+.PP
+If
+\fBdig\fR
+has been built with IDN (internationalized domain name) support, it can accept and display non\-ASCII domain names\&.
+\fBdig\fR
+appropriately converts character encoding of domain name before sending a request to DNS server or displaying a reply from the server\&. If you\*(Aqd like to turn off the IDN support for some reason, use parameters
+\fI+noidnin\fR
+and
+\fI+noidnout\fR\&.

+
+    <para><command>dig</command> is a flexible tool
+      for interrogating DNS name servers.  It performs DNS lookups and
+      displays the answers that are returned from the name server(s) that
+      were queried.  Most DNS administrators use <command>dig</command> to
+      troubleshoot DNS problems because of its flexibility, ease of use and
+      clarity of output.  Other lookup tools tend to have less functionality
+      than <command>dig</command>.
+    </para>
+
+    <para>
+      Although <command>dig</command> is normally used with
+      command-line
+      arguments, it also has a batch mode of operation for reading lookup
+      requests from a file.  A brief summary of its command-line arguments
+      and options is printed when the <option>-h</option> option is given.
+      Unlike earlier versions, the BIND 9 implementation of
+      <command>dig</command> allows multiple lookups to be issued
+      from the
+      command line.
+    </para>
+
+    <para>
+      Unless it is told to query a specific name server,
+      <command>dig</command> will try each of the servers listed in
+      <filename>/etc/resolv.conf</filename>. If no usable server addresses
+      are found, <command>dig</command> will send the query to the local
+      host.
+    </para>
+
+    <para>
+      When no command line arguments or options are given,
+      <command>dig</command> will perform an NS query for "." (the root).
+    </para>
+
+    <para>
+      It is possible to set per-user defaults for <command>dig</command> via
+      <filename>${HOME}/.digrc</filename>.  This file is read and
+      any options in it
+      are applied before the command line arguments.
+    </para>
+
+    <para>
+      The IN and CH class names overlap with the IN and CH top level
+      domain names.  Either use the <option>-t</option> and
+      <option>-c</option> options to specify the type and class,
+      use the <option>-q</option> the specify the domain name, or
+      use "IN." and "CH." when looking up these top level domains.

+
+  <refsection><info><title>SIMPLE USAGE</title></info>
+
+
+    <para>
+      A typical invocation of <command>dig</command> looks like:
+      <programlisting> dig @server name type </programlisting>
+      where:
+
+      <variablelist>
+
+	<varlistentry>
+	  <term><constant>server</constant></term>
+	  <listitem>
+	    <para>
+	      is the name or IP address of the name server to query.  This
+	      can be an IPv4 address in dotted-decimal notation or an IPv6
+	      address in colon-delimited notation.  When the supplied
+	      <parameter>server</parameter> argument is a hostname,
+	      <command>dig</command> resolves that name before querying
+	      that name server.
+	    </para>
+	    <para>
+	      If no <parameter>server</parameter> argument is
+	      provided, <command>dig</command> consults
+	      <filename>/etc/resolv.conf</filename>; if an
+	      address is found there, it queries the name server at
+	      that address. If either of the <option>-4</option> or
+	      <option>-6</option> options are in use, then
+	      only addresses for the corresponding transport
+	      will be tried.  If no usable addresses are found,
+	      <command>dig</command> will send the query to the
+	      local host.  The reply from the name server that
+	      responds is displayed.
+	    </para>
+	  </listitem>
+	</varlistentry>
+
+	<varlistentry>
+	  <term><constant>name</constant></term>
+	  <listitem>
+	    <para>

+    <para>
+      The BIND 9 implementation of <command>dig </command>
+      supports
+      specifying multiple queries on the command line (in addition to
+      supporting the <option>-f</option> batch file option).  Each of those
+      queries can be supplied with its own set of flags, options and query
+      options.
+    </para>
+
+    <para>
+      In this case, each <parameter>query</parameter> argument
+      represent an
+      individual query in the command-line syntax described above.  Each
+      consists of any of the standard options and flags, the name to be
+      looked up, an optional query type and class and any query options that
+      should be applied to that query.
+    </para>
+
+    <para>
+      A global set of query options, which should be applied to all queries,
+      can also be supplied.  These global query options must precede the
+      first tuple of name, class, type, options, flags, and query options
+      supplied on the command line.  Any global query options (except
+      the <option>+[no]cmd</option> option) can be
+      overridden by a query-specific set of query options.  For example:
+      <programlisting>
+dig +qr www.isc.org any -x 127.0.0.1 isc.org ns +noqr
+</programlisting>
+      shows how <command>dig</command> could be used from the
+      command line
+      to make three lookups: an ANY query for <literal>www.isc.org</literal>, a
+      reverse lookup of 127.0.0.1 and a query for the NS records of
+      <literal>isc.org</literal>.
+
+      A global query option of <parameter>+qr</parameter> is
+      applied, so
+      that <command>dig</command> shows the initial query it made
+      for each
+      lookup.  The final query has a local query option of
+      <parameter>+noqr</parameter> which means that <command>dig</command>
+      will not print the initial query when it looks up the NS records for
+      <literal>isc.org</literal>.

+
+    <p><span class="command"><strong>dig</strong></span> is a flexible tool
+      for interrogating DNS name servers.  It performs DNS lookups and
+      displays the answers that are returned from the name server(s) that
+      were queried.  Most DNS administrators use <span class="command"><strong>dig</strong></span> to
+      troubleshoot DNS problems because of its flexibility, ease of use and
+      clarity of output.  Other lookup tools tend to have less functionality
+      than <span class="command"><strong>dig</strong></span>.
+    </p>
+
+    <p>
+      Although <span class="command"><strong>dig</strong></span> is normally used with
+      command-line
+      arguments, it also has a batch mode of operation for reading lookup
+      requests from a file.  A brief summary of its command-line arguments
+      and options is printed when the <code class="option">-h</code> option is given.
+      Unlike earlier versions, the BIND 9 implementation of
+      <span class="command"><strong>dig</strong></span> allows multiple lookups to be issued
+      from the
+      command line.
+    </p>
+
+    <p>
+      Unless it is told to query a specific name server,
+      <span class="command"><strong>dig</strong></span> will try each of the servers listed in
+      <code class="filename">/etc/resolv.conf</code>. If no usable server addresses
+      are found, <span class="command"><strong>dig</strong></span> will send the query to the local
+      host.
+    </p>
+
+    <p>
+      When no command line arguments or options are given,
+      <span class="command"><strong>dig</strong></span> will perform an NS query for "." (the root).
+    </p>
+
+    <p>
+      It is possible to set per-user defaults for <span class="command"><strong>dig</strong></span> via
+      <code class="filename">${HOME}/.digrc</code>.  This file is read and
+      any options in it
+      are applied before the command line arguments.
+    </p>
+
+    <p>
+      The IN and CH class names overlap with the IN and CH top level
+      domain names.  Either use the <code class="option">-t</code> and
+      <code class="option">-c</code> options to specify the type and class,
+      use the <code class="option">-q</code> the specify the domain name, or
+      use "IN." and "CH." when looking up these top level domains.

+
+
+    <p>
+      A typical invocation of <span class="command"><strong>dig</strong></span> looks like:
+      </p>
+<pre class="programlisting"> dig @server name type </pre>
+<p>
+      where:
+
+      </p>
+<div class="variablelist"><dl class="variablelist">
+<dt><span class="term"><code class="constant">server</code></span></dt>
+<dd>
+	    <p>
+	      is the name or IP address of the name server to query.  This
+	      can be an IPv4 address in dotted-decimal notation or an IPv6
+	      address in colon-delimited notation.  When the supplied
+	      <em class="parameter"><code>server</code></em> argument is a hostname,
+	      <span class="command"><strong>dig</strong></span> resolves that name before querying
+	      that name server.
+	    </p>
+	    <p>
+	      If no <em class="parameter"><code>server</code></em> argument is
+	      provided, <span class="command"><strong>dig</strong></span> consults
+	      <code class="filename">/etc/resolv.conf</code>; if an
+	      address is found there, it queries the name server at
+	      that address. If either of the <code class="option">-4</code> or
+	      <code class="option">-6</code> options are in use, then
+	      only addresses for the corresponding transport
+	      will be tried.  If no usable addresses are found,
+	      <span class="command"><strong>dig</strong></span> will send the query to the
+	      local host.  The reply from the name server that
+	      responds is displayed.

+      provides a number of query options which affect

+      these set or reset flag bits in the query header, some determine which
+      sections of the answer get printed, and others determine the timeout
+      and retry strategies.
+    </p>
+
+    <p>
+      Each query option is identified by a keyword preceded by a plus sign
+      (<code class="literal">+</code>).  Some keywords set or reset an
+      option.  These may be preceded
+      by the string <code class="literal">no</code> to negate the meaning of
+      that keyword.  Other

+
+
+    <p>
+      The BIND 9 implementation of <span class="command"><strong>dig </strong></span>
+      supports
+      specifying multiple queries on the command line (in addition to
+      supporting the <code class="option">-f</code> batch file option).  Each of those
+      queries can be supplied with its own set of flags, options and query
+      options.
+    </p>
+
+    <p>
+      In this case, each <em class="parameter"><code>query</code></em> argument
+      represent an
+      individual query in the command-line syntax described above.  Each
+      consists of any of the standard options and flags, the name to be
+      looked up, an optional query type and class and any query options that
+      should be applied to that query.
+    </p>
+
+    <p>
+      A global set of query options, which should be applied to all queries,
+      can also be supplied.  These global query options must precede the
+      first tuple of name, class, type, options, flags, and query options
+      supplied on the command line.  Any global query options (except
+      the <code class="option">+[no]cmd</code> option) can be
+      overridden by a query-specific set of query options.  For example:
+      </p>
+<pre class="programlisting">
+dig +qr www.isc.org any -x 127.0.0.1 isc.org ns +noqr
+</pre>
+<p>
+      shows how <span class="command"><strong>dig</strong></span> could be used from the
+      command line
+      to make three lookups: an ANY query for <code class="literal">www.isc.org</code>, a
+      reverse lookup of 127.0.0.1 and a query for the NS records of
+      <code class="literal">isc.org</code>.
+
+      A global query option of <em class="parameter"><code>+qr</code></em> is
+      applied, so
+      that <span class="command"><strong>dig</strong></span> shows the initial query it made
+      for each
+      lookup.  The final query has a local query option of
+      <em class="parameter"><code>+noqr</code></em> which means that <span class="command"><strong>dig</strong></span>
+      will not print the initial query when it looks up the NS records for
+      <code class="literal">isc.org</code>.

+.SH "DESCRIPTION"
+.PP
+\fBhost\fR
+is a simple utility for performing DNS lookups\&. It is normally used to convert names to IP addresses and vice versa\&. When no arguments or options are given,
+\fBhost\fR
+prints a short summary of its command line arguments and options\&.
+.PP
+\fIname\fR
+is the domain name that is to be looked up\&. It can also be a dotted\-decimal IPv4 address or a colon\-delimited IPv6 address, in which case
+\fBhost\fR
+will by default perform a reverse lookup for that address\&.
+\fIserver\fR
+is an optional argument which is either the name or IP address of the name server that
+\fBhost\fR
+should query instead of the server or servers listed in
+/etc/resolv\&.conf\&.
+.SH "OPTIONS"
+.PP
+\-4
+.RS 4
+Use IPv4 only for query transport\&. See also the
+\fB\-6\fR
+option\&.
+.RE
+.PP
+\-6
+.RS 4
+Use IPv6 only for query transport\&. See also the
+\fB\-4\fR
+option\&.
+.RE
+.PP
+\-a
+.RS 4
+"All"\&. The
+\fB\-a\fR
+option is normally equivalent to
+\fB\-v \-t \fR\fBANY\fR\&. It also affects the behaviour of the
+\fB\-l\fR
+list zone option\&.
+.RE
+.PP
+\-c \fIclass\fR
+.RS 4
+Query class: This can be used to lookup HS (Hesiod) or CH (Chaosnet) class resource records\&. The default class is IN (Internet)\&.
+.RE
+.PP
+\-C
+.RS 4
+Check consistency:
+\fBhost\fR
+will query the SOA records for zone
+\fIname\fR
+from all the listed authoritative name servers for that zone\&. The list of name servers is defined by the NS records that are found for the zone\&.
+.RE
+.PP
+\-d
+.RS 4
+Print debugging traces\&. Equivalent to the
+\fB\-v\fR
+verbose option\&.

+    <para><command>host</command>
+      is a simple utility for performing DNS lookups.
+      It is normally used to convert names to IP addresses and vice versa.
+      When no arguments or options are given,
+      <command>host</command>
+      prints a short summary of its command line arguments and options.
+    </para>
+
+    <para><parameter>name</parameter> is the domain name that is to be
+      looked
+      up.  It can also be a dotted-decimal IPv4 address or a colon-delimited
+      IPv6 address, in which case <command>host</command> will by
+      default
+      perform a reverse lookup for that address.
+      <parameter>server</parameter> is an optional argument which
+      is either
+      the name or IP address of the name server that <command>host</command>
+      should query instead of the server or servers listed in

+
+
+    <p><span class="command"><strong>host</strong></span>
+      is a simple utility for performing DNS lookups.
+      It is normally used to convert names to IP addresses and vice versa.
+      When no arguments or options are given,
+      <span class="command"><strong>host</strong></span>
+      prints a short summary of its command line arguments and options.
+    </p>
+
+    <p><em class="parameter"><code>name</code></em> is the domain name that is to be
+      looked
+      up.  It can also be a dotted-decimal IPv4 address or a colon-delimited
+      IPv6 address, in which case <span class="command"><strong>host</strong></span> will by
+      default
+      perform a reverse lookup for that address.
+      <em class="parameter"><code>server</code></em> is an optional argument which
+      is either
+      the name or IP address of the name server that <span class="command"><strong>host</strong></span>
+      should query instead of the server or servers listed in
+      <code class="filename">/etc/resolv.conf</code>.
+    </p>
+
+  </div>
+
+  <div class="refsection">

+	    Obsolete.
+	    Use the IP6.INT domain for reverse lookups of IPv6

+.SH "NAME"
+nslookup \- query Internet name servers interactively
+.SH "SYNOPSIS"
+.HP \w'\fBnslookup\fR\ 'u
+\fBnslookup\fR [\fB\-option\fR] [name\ |\ \-] [server]
+.SH "DESCRIPTION"
+.PP
+\fBNslookup\fR
+is a program to query Internet domain name servers\&.
+\fBNslookup\fR
+has two modes: interactive and non\-interactive\&. Interactive mode allows the user to query name servers for information about various hosts and domains or to print a list of hosts in a domain\&. Non\-interactive mode is used to print just the name and requested information for a host or domain\&.
+.SH "ARGUMENTS"
+.PP
+Interactive mode is entered in the following cases:
+.sp
+.RS 4
+.ie n \{\
+\h'-04' 1.\h'+01'\c
+.\}
+.el \{\
+.sp -1
+.IP "  1." 4.2
+.\}
+when no arguments are given (the default name server will be used)
+.RE
+.sp
+.RS 4
+.ie n \{\
+\h'-04' 2.\h'+01'\c
+.\}
+.el \{\
+.sp -1
+.IP "  2." 4.2
+.\}
+when the first argument is a hyphen (\-) and the second argument is the host name or Internet address of a name server\&.
+.RE
+.PP
+Non\-interactive mode is used when the name or Internet address of the host to be looked up is given as the first argument\&. The optional second argument specifies the host name or address of a name server\&.
+.PP
+Options can also be specified on the command line if they precede the arguments and are prefixed with a hyphen\&. For example, to change the default query type to host information, and the initial timeout to 10 seconds, type:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+nslookup \-query=hinfo  \-timeout=10
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+The
+\fB\-version\fR
+option causes
+\fBnslookup\fR
+to print the version number and immediately exits\&.
+.SH "INTERACTIVE COMMANDS"
+.PP
+\fBhost\fR [server]
+.RS 4
+Look up information for host using the current default server or using server, if specified\&. If host is an Internet address and the query type is A or PTR, the name of the host is returned\&. If host is a name and does not have a trailing period, the search list is used to qualify the name\&.
+.sp
+To look up a host not in the current domain, append a period to the name\&.
+.RE
+.PP
+\fBserver\fR \fIdomain\fR
+.RS 4
+.RE
+.PP
+\fBlserver\fR \fIdomain\fR
+.RS 4
+Change the default server to
+\fIdomain\fR;
+\fBlserver\fR
+uses the initial server to look up information about
+\fIdomain\fR, while
+\fBserver\fR
+uses the current default server\&. If an authoritative answer can\*(Aqt be found, the names of servers that might have the answer are returned\&.

+
+    <para><command>Nslookup</command>
+      is a program to query Internet domain name servers.  <command>Nslookup</command>
+      has two modes: interactive and non-interactive.  Interactive mode allows
+      the user to query name servers for information about various hosts and
+      domains or to print a list of hosts in a domain.  Non-interactive mode
+      is
+      used to print just the name and requested information for a host or
+      domain.
+    </para>
+  </refsection>
+
+  <refsection><info><title>ARGUMENTS</title></info>
+
+    <para>
+      Interactive mode is entered in the following cases:
+      <orderedlist numeration="loweralpha" inheritnum="ignore" continuation="restarts">
+        <listitem>
+          <para>
+            when no arguments are given (the default name server will be used)
+          </para>
+        </listitem>
+        <listitem>
+          <para>
+            when the first argument is a hyphen (-) and the second argument is
+            the host name or Internet address of a name server.
+          </para>
+        </listitem>
+      </orderedlist>
+    </para>
+
+    <para>
+      Non-interactive mode is used when the name or Internet address of the
+      host to be looked up is given as the first argument. The optional second
+      argument specifies the host name or address of a name server.
+    </para>
+
+    <para>
+      Options can also be specified on the command line if they precede the
+      arguments and are prefixed with a hyphen.  For example, to
+      change the default query type to host information, and the initial
+      timeout to 10 seconds, type:
+      <!-- <informalexample> produces bad nroff. -->
+        <programlisting>
+nslookup -query=hinfo  -timeout=10
+</programlisting>
+      <!-- </informalexample> -->
+    </para>
+    <para>
+      The <option>-version</option> option causes
+      <command>nslookup</command> to print the version
+      number and immediately exits.

+            the query type is A or PTR, the name of the host is returned.
+            If host is a name and does not have a trailing period, the
+            search list is used to qualify the name.

+
+    <p><span class="command"><strong>Nslookup</strong></span>
+      is a program to query Internet domain name servers.  <span class="command"><strong>Nslookup</strong></span>
+      has two modes: interactive and non-interactive.  Interactive mode allows
+      the user to query name servers for information about various hosts and
+      domains or to print a list of hosts in a domain.  Non-interactive mode
+      is
+      used to print just the name and requested information for a host or
+      domain.
+    </p>
+  </div>
+
+  <div class="refsection">
+<a name="id-1.8"></a><h2>ARGUMENTS</h2>
+
+    <p>
+      Interactive mode is entered in the following cases:
+      </p>
+<div class="orderedlist"><ol class="orderedlist" type="a">
+<li class="listitem">
+          <p>
+            when no arguments are given (the default name server will be used)
+          </p>
+        </li>
+<li class="listitem">
+          <p>
+            when the first argument is a hyphen (-) and the second argument is
+            the host name or Internet address of a name server.
+          </p>
+        </li>
+</ol></div>
+<p>
+    </p>
+
+    <p>
+      Non-interactive mode is used when the name or Internet address of the
+      host to be looked up is given as the first argument. The optional second
+      argument specifies the host name or address of a name server.
+    </p>
+
+    <p>
+      Options can also be specified on the command line if they precede the
+      arguments and are prefixed with a hyphen.  For example, to
+      change the default query type to host information, and the initial
+      timeout to 10 seconds, type:
+      
+        </p>
+<pre class="programlisting">
+nslookup -query=hinfo  -timeout=10
+</pre>
+<p>
+      
+    </p>
+    <p>
+      The <code class="option">-version</code> option causes
+      <span class="command"><strong>nslookup</strong></span> to print the version
+      number and immediately exits.
+    </p>
+
+  </div>

+            Look up information for host using the current default server or
+            using server, if specified.  If host is an Internet address and
+            the query type is A or PTR, the name of the host is returned.
+            If host is a name and does not have a trailing period, the

+.SH "DESCRIPTION"
+.PP
+\fBdnssec\-dsfromkey\fR
+outputs the Delegation Signer (DS) resource record (RR), as defined in RFC 3658 and RFC 4509, for the given key(s)\&.
+.SH "OPTIONS"
+.PP
+\-1
+.RS 4
+Use SHA\-1 as the digest algorithm (the default is to use both SHA\-1 and SHA\-256)\&.
+.RE
+.PP
+\-2
+.RS 4
+Use SHA\-256 as the digest algorithm\&.
+.RE
+.PP
+\-a \fIalgorithm\fR
+.RS 4
+Select the digest algorithm\&. The value of
+\fBalgorithm\fR
+must be one of SHA\-1 (SHA1), SHA\-256 (SHA256), GOST or SHA\-384 (SHA384)\&. These values are case insensitive\&.
+.RE
+.PP
+\-C
+.RS 4
+Generate CDS records rather than DS records\&. This is mutually exclusive with generating lookaside records\&.
+.RE
+.PP
+\-T \fITTL\fR
+.RS 4
+Specifies the TTL of the DS records\&.
+.RE
+.PP
+\-K \fIdirectory\fR
+.RS 4
+Look for key files (or, in keyset mode,
+keyset\-
+files) in
+\fBdirectory\fR\&.
+.RE
+.PP
+\-f \fIfile\fR
+.RS 4
+Zone file mode: in place of the keyfile name, the argument is the DNS domain name of a zone master file, which can be read from
+\fBfile\fR\&. If the zone name is the same as
+\fBfile\fR, then it may be omitted\&.
+.sp
+If
+\fBfile\fR
+is set to
+"\-", then the zone data is read from the standard input\&. This makes it possible to use the output of the
+\fBdig\fR
+command as input, as in:
+.sp
+\fBdig dnskey example\&.com | dnssec\-dsfromkey \-f \- example\&.com\fR
+.RE
+.PP
+\-A
+.RS 4
+Include ZSKs when generating DS records\&. Without this option, only keys which have the KSK flag set will be converted to DS records and printed\&. Useful only in zone file mode\&.
+.RE
+.PP
+\-l \fIdomain\fR
+.RS 4
+Generate a DLV set instead of a DS set\&. The specified
+\fBdomain\fR
+is appended to the name for each record in the set\&. The DNSSEC Lookaside Validation (DLV) RR is described in RFC 4431\&. This is mutually exclusive with generating CDS records\&.
+.RE
+.PP
+\-s
+.RS 4
+Keyset mode: in place of the keyfile name, the argument is the DNS domain name of a keyset file\&.
+.RE
+.PP
+\-c \fIclass\fR
+.RS 4
+Specifies the DNS class (default is IN)\&. Useful only in keyset or zone file mode\&.
+.RE
+.PP
+\-v \fIlevel\fR
+.RS 4
+Sets the debugging level\&.
+.RE
+.PP
+\-h
+.RS 4
+Prints usage information\&.
+.RE
+.PP
+\-V
+.RS 4
+Prints version information\&.
+.RE
+.SH "EXAMPLE"
+.PP
+To build the SHA\-256 DS RR from the
+\fBKexample\&.com\&.+003+26160\fR
+keyfile name, the following command would be issued:
+.PP
+\fBdnssec\-dsfromkey \-2 Kexample\&.com\&.+003+26160\fR
+.PP
+The command would print something like:
+.PP
+\fBexample\&.com\&. IN DS 26160 5 2 3A1EADA7A74B8D0BA86726B0C227AA85AB8BBD2B2004F41A868A54F0 C5EA0B94\fR
+.SH "FILES"
+.PP
+The keyfile can be designed by the key identification
+Knnnn\&.+aaa+iiiii
+or the full file name
+Knnnn\&.+aaa+iiiii\&.key
+as generated by
+dnssec\-keygen(8)\&.
+.PP
+The keyset file name is built from the
+\fBdirectory\fR, the string
+keyset\-
+and the
+\fBdnsname\fR\&.
+.SH "CAVEAT"
+.PP
+A keyfile error can give a "file not found" even if the file exists\&.
+.SH "SEE ALSO"
+.PP
+\fBdnssec-keygen\fR(8),
+\fBdnssec-signzone\fR(8),
+BIND 9 Administrator Reference Manual,

The DNSKEY record may be read from an existing \&.key file, in which case a corresponding \&.private file will be generated, or it may be read from any other file or from the standard input, in which case both \&.key and \&.private files will be generated\&.
+.PP
+The newly\-created \&.private file does
+\fInot\fR
+contain private key data, and cannot be used for signing\&. However, having a \&.private file makes it possible to set publication (\fB\-P\fR) and deletion (\fB\-D\fR) times for the key, which means the public key can be added to and removed from the DNSKEY RRset on schedule even if the true private key is stored offline\&.
+.SH "OPTIONS"
+.PP
+\-f \fIfilename\fR
+.RS 4
+Zone file mode: instead of a public keyfile name, the argument is the DNS domain name of a zone master file, which can be read from
+\fBfile\fR\&. If the domain name is the same as
+\fBfile\fR, then it may be omitted\&.
+.sp
+If
+\fBfile\fR
+is set to
+"\-", then the zone data is read from the standard input\&.
+.RE
+.PP
+\-K \fIdirectory\fR
+.RS 4
+Sets the directory in which the key files are to reside\&.
+.RE
+.PP
+\-L \fIttl\fR
+.RS 4
+Sets the default TTL to use for this key when it is converted into a DNSKEY RR\&. If the key is imported into a zone, this is the TTL that will be used for it, unless there was already a DNSKEY RRset in place, in which case the existing TTL would take precedence\&. Setting the default TTL to
+0
+or
+none
+removes it\&.

+Emit usage message and exit\&.
+.RE
+.PP
+\-v \fIlevel\fR
+.RS 4
+Sets the debugging level\&.

+.RE
+.SH "TIMING OPTIONS"
+.PP
+Dates can be expressed in the format YYYYMMDD or YYYYMMDDHHMMSS\&. If the argument begins with a \*(Aq+\*(Aq or \*(Aq\-\*(Aq, it is interpreted as an offset from the present time\&. For convenience, if such an offset is followed by one of the suffixes \*(Aqy\*(Aq, \*(Aqmo\*(Aq, \*(Aqw\*(Aq, \*(Aqd\*(Aq, \*(Aqh\*(Aq, or \*(Aqmi\*(Aq, then the offset is computed in years (defined as 365 24\-hour days, ignoring leap years), months (defined as 30 24\-hour days), weeks, days, hours, or minutes, respectively\&. Without a suffix, the offset is computed in seconds\&. To explicitly prevent a date from being set, use \*(Aqnone\*(Aq or \*(Aqnever\*(Aq\&.
+.PP
+\-P \fIdate/offset\fR
+.RS 4
+Sets the date on which a key is to be published to the zone\&. After that date, the key will be included in the zone but will not be used to sign it\&.
+.RE
+.PP
+\-P sync \fIdate/offset\fR
+.RS 4
+Sets the date on which CDS and CDNSKEY records that match this key are to be published to the zone\&.
+.RE
+.PP
+\-D \fIdate/offset\fR

+      from the standard input, in which case both .key and .private

+      The newly-created .private file does <emphasis>not</emphasis>

+      (<option>-D</option>) times for the key, which means the

+.SH "DESCRIPTION"
+.PP
+\fBdnssec\-keyfromlabel\fR
+generates a key pair of files that referencing a key object stored in a cryptographic hardware service module (HSM)\&. The private key file can be used for DNSSEC signing of zone data as if it were a conventional signing key created by
+\fBdnssec\-keygen\fR, but the key material is stored within the HSM, and the actual signing takes place there\&.
+.PP
+The
+\fBname\fR
+of the key is specified on the command line\&. This must match the name of the zone for which the key is being generated\&.
+.SH "OPTIONS"
+.PP
+\-a \fIalgorithm\fR
+.RS 4
+Selects the cryptographic algorithm\&. The value of
+\fBalgorithm\fR
+must be one of RSAMD5, RSASHA1, DSA, NSEC3RSASHA1, NSEC3DSA, RSASHA256, RSASHA512, ECCGOST, ECDSAP256SHA256, ECDSAP384SHA384, ED25519 or ED448\&. These values are case insensitive\&.
+.sp
+If no algorithm is specified, then RSASHA1 will be used by default, unless the
+\fB\-3\fR
+option is specified, in which case NSEC3RSASHA1 will be used instead\&. (If
+\fB\-3\fR
+is used and an algorithm is specified, that algorithm will be checked for compatibility with NSEC3\&.)
+.sp
+Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement algorithm, and DSA is recommended\&.
+.sp
+Note 2: DH automatically sets the \-k flag\&.
+.RE
+.PP
+\-3
+.RS 4
+Use an NSEC3\-capable algorithm to generate a DNSSEC key\&. If this option is used and no algorithm is explicitly set on the command line, NSEC3RSASHA1 will be used by default\&.
+.RE
+.PP
+\-E \fIengine\fR
+.RS 4
+Specifies the cryptographic hardware to use\&.

+When BIND is built with OpenSSL PKCS#11 support, this defaults to the string "pkcs11", which identifies an OpenSSL engine that can drive a cryptographic accelerator or hardware service module\&.

+Specifies the label for a key pair in the crypto hardware\&.
+.sp
+When

+9 is built with OpenSSL\-based PKCS#11 support, the label is an arbitrary string that identifies a particular key\&. It may be preceded by an optional OpenSSL engine name, followed by a colon, as in "pkcs11:\fIkeylabel\fR"\&.
+.sp
+When

+9 is built with native PKCS#11 support, the label is a PKCS#11 URI string in the format "pkcs11:\fBkeyword\fR=\fIvalue\fR[;\fBkeyword\fR=\fIvalue\fR;\&.\&.\&.]" Keywords include "token", which identifies the HSM; "object", which identifies the key; and "pin\-source", which identifies a file from which the HSM\*(Aqs PIN code can be obtained\&. The label will be stored in the on\-disk "private" file\&.
+.sp
+If the label contains a
+\fBpin\-source\fR
+field, tools using the generated key files will be able to use the HSM for signing and other operations without any need for an operator to manually enter a PIN\&.

+      generates a key pair of files that referencing a key object stored
+      in a cryptographic hardware service module (HSM).  The private key
+      file can be used for DNSSEC signing of zone data as if it were a
+      conventional signing key created by <span class="command"><strong>dnssec-keygen</strong></span>,
+      but the key material is stored within the HSM, and the actual signing
+      takes place there.
+    </p>
+    <p>
+      The <code class="option">name</code> of the key is specified on the command
+      line.  This must match the name of the zone for which the key is
+      being generated.

+	    ECDSAP256SHA256, ECDSAP384SHA384, ED25519 or ED448.
+	    These values are case insensitive.
+	  </p>
+	  <p>
+	    If no algorithm is specified, then RSASHA1 will be used by
+	    default, unless the <code class="option">-3</code> option is specified,
+	    in which case NSEC3RSASHA1 will be used instead.  (If
+	    <code class="option">-3</code> is used and an algorithm is specified,
+	    that algorithm will be checked for compatibility with NSEC3.)

+.SH "DESCRIPTION"
+.PP
+\fBdnssec\-keygen\fR
+generates keys for DNSSEC (Secure DNS), as defined in RFC 2535 and RFC 4034\&. It can also generate keys for use with TSIG (Transaction Signatures) as defined in RFC 2845, or TKEY (Transaction Key) as defined in RFC 2930\&.
+.PP
+The
+\fBname\fR
+of the key is specified on the command line\&. For DNSSEC keys, this must match the name of the zone for which the key is being generated\&.
+.SH "OPTIONS"
+.PP
+\-a \fIalgorithm\fR
+.RS 4
+Selects the cryptographic algorithm\&. For DNSSEC keys, the value of
+\fBalgorithm\fR
+must be one of RSAMD5, RSASHA1, DSA, NSEC3RSASHA1, NSEC3DSA, RSASHA256, RSASHA512, ECCGOST, ECDSAP256SHA256, ECDSAP384SHA384, ED25519 or ED448\&. For TSIG/TKEY, the value must be DH (Diffie Hellman), HMAC\-MD5, HMAC\-SHA1, HMAC\-SHA224, HMAC\-SHA256, HMAC\-SHA384, or HMAC\-SHA512\&. These values are case insensitive\&.
+.sp
+If no algorithm is specified, then RSASHA1 will be used by default, unless the
+\fB\-3\fR
+option is specified, in which case NSEC3RSASHA1 will be used instead\&. (If
+\fB\-3\fR
+is used and an algorithm is specified, that algorithm will be checked for compatibility with NSEC3\&.)
+.sp
+Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement algorithm, and DSA is recommended\&. For TSIG, HMAC\-MD5 is mandatory\&.
+.sp
+Note 2: DH, HMAC\-MD5, and HMAC\-SHA1 through HMAC\-SHA512 automatically set the \-T KEY option\&.
+.RE
+.PP
+\-b \fIkeysize\fR
+.RS 4
+Specifies the number of bits in the key\&. The choice of key size depends on the algorithm used\&. RSA keys must be between 512 and 2048 bits\&. Diffie Hellman keys must be between 128 and 4096 bits\&. DSA keys must be between 512 and 1024 bits and an exact multiple of 64\&. HMAC keys must be between 1 and 512 bits\&. Elliptic curve algorithms don\*(Aqt need this parameter\&.
+.sp
+The key size does not need to be specified if using a default algorithm\&. The default key size is 1024 bits for zone signing keys (ZSKs) and 2048 bits for key signing keys (KSKs, generated with
+\fB\-f KSK\fR)\&. However, if an algorithm is explicitly specified with the
+\fB\-a\fR, then there is no default key size, and the
+\fB\-b\fR
+must be used\&.
+.RE
+.PP
+\-n \fInametype\fR
+.RS 4
+Specifies the owner type of the key\&. The value of
+\fBnametype\fR
+must either be ZONE (for a DNSSEC zone key (KEY/DNSKEY)), HOST or ENTITY (for a key associated with a host (KEY)), USER (for a key associated with a user(KEY)) or OTHER (DNSKEY)\&. These values are case insensitive\&. Defaults to ZONE for DNSKEY generation\&.
+.RE
+.PP
+\-3
+.RS 4
+Use an NSEC3\-capable algorithm to generate a DNSSEC key\&. If this option is used and no algorithm is explicitly set on the command line, NSEC3RSASHA1 will be used by default\&. Note that RSASHA256, RSASHA512, ECCGOST, ECDSAP256SHA256, ECDSAP384SHA384, ED25519 and ED448 algorithms are NSEC3\-capable\&.
+.RE
+.PP
+\-C
+.RS 4
+Compatibility mode: generates an old\-style key, without any metadata\&. By default,
+\fBdnssec\-keygen\fR
+will include the key\*(Aqs creation date in the metadata stored with the private key, and other dates may be set there as well (publication date, activation date, etc)\&. Keys that include this data may be incompatible with older versions of BIND; the
+\fB\-C\fR
+option suppresses them\&.
+.RE
+.PP
+\-c \fIclass\fR
+.RS 4
+Indicates that the DNS record containing the key should have the specified class\&. If not specified, class IN is used\&.
+.RE
+.PP
+\-E \fIengine\fR
+.RS 4
+Specifies the cryptographic hardware to use, when applicable\&.
+.sp
+When BIND is built with OpenSSL PKCS#11 support, this defaults to the string "pkcs11", which identifies an OpenSSL engine that can drive a cryptographic accelerator or hardware service module\&. When BIND is built with native PKCS#11 cryptography (\-\-enable\-native\-pkcs11), it defaults to the path of the PKCS#11 provider library specified via "\-\-with\-pkcs11"\&.
+.RE
+.PP
+\-f \fIflag\fR
+.RS 4
+Set the specified flag in the flag field of the KEY/DNSKEY record\&. The only recognized flags are KSK (Key Signing Key) and REVOKE\&.
+.RE
+.PP
+\-G
+.RS 4
+Generate a key, but do not publish it or sign with it\&. This option is incompatible with \-P and \-A\&.
+.RE
+.PP
+\-g \fIgenerator\fR
+.RS 4
+If generating a Diffie Hellman key, use this generator\&. Allowed values are 2 and 5\&. If no generator is specified, a known prime from RFC 2539 will be used if possible; otherwise the default is 2\&.
+.RE
+.PP
+\-h
+.RS 4
+Prints a short summary of the options and arguments to
+\fBdnssec\-keygen\fR\&.
+.RE
+.PP
+\-K \fIdirectory\fR
+.RS 4
+Sets the directory in which the key files are to be written\&.
+.RE
+.PP
+\-k
+.RS 4
+Deprecated in favor of \-T KEY\&.
+.RE
+.PP
+\-L \fIttl\fR
+.RS 4
+Sets the default TTL to use for this key when it is converted into a DNSKEY RR\&. If the key is imported into a zone, this is the TTL that will be used for it, unless there was already a DNSKEY RRset in place, in which case the existing TTL would take precedence\&. If this value is not set and there is no existing DNSKEY RRset, the TTL will default to the SOA TTL\&. Setting the default TTL to
+0
+or
+none
+is the same as leaving it unset\&.
+.RE
+.PP
+\-p \fIprotocol\fR
+.RS 4
+Sets the protocol value for the generated key\&. The protocol is a number between 0 and 255\&. The default is 3 (DNSSEC)\&. Other possible values for this argument are listed in RFC 2535 and its successors\&.
+.RE
+.PP
+\-q
+.RS 4
+Quiet mode: Suppresses unnecessary output, including progress indication\&. Without this option, when
+\fBdnssec\-keygen\fR
+is run interactively to generate an RSA or DSA key pair, it will print a string of symbols to
+stderr
+indicating the progress of the key generation\&. A \*(Aq\&.\*(Aq indicates that a random number has been found which passed an initial sieve test; \*(Aq+\*(Aq means a number has passed a single round of the Miller\-Rabin primality test; a space means that the number has passed all the tests and is a satisfactory key\&.
+.RE
+.PP
+\-r \fIrandomdev\fR
+.RS 4
+Specifies the source of randomness\&. If the operating system does not provide a
+/dev/random
+or equivalent device, the default source of randomness is keyboard input\&.
+randomdev
+specifies the name of a character device or file containing random data to be used instead of the default\&. The special value
+keyboard
+indicates that keyboard input should be used\&.
+.RE
+.PP
+\-S \fIkey\fR
+.RS 4
+Create a new key which is an explicit successor to an existing key\&. The name, algorithm, size, and type of the key will be set to match the existing key\&. The activation date of the new key will be set to the inactivation date of the existing one\&. The publication date will be set to the activation date minus the prepublication interval, which defaults to 30 days\&.
+.RE
+.PP
+\-s \fIstrength\fR
+.RS 4
+Specifies the strength value of the key\&. The strength is a number between 0 and 15, and currently has no defined purpose in DNSSEC\&.
+.RE
+.PP
+\-T \fIrrtype\fR
+.RS 4
+Specifies the resource record type to use for the key\&.
+\fBrrtype\fR
+must be either DNSKEY or KEY\&. The default is DNSKEY when using a DNSSEC algorithm, but it can be overridden to KEY for use with SIG(0)\&.
+Using any TSIG algorithm (HMAC\-* or DH) forces this option to KEY\&.
+.RE
+.PP
+\-t \fItype\fR
+.RS 4
+Indicates the use of the key\&.
+\fBtype\fR
+must be one of AUTHCONF, NOAUTHCONF, NOAUTH, or NOCONF\&. The default is AUTHCONF\&. AUTH refers to the ability to authenticate data, and CONF the ability to encrypt data\&.

+Dates can be expressed in the format YYYYMMDD or YYYYMMDDHHMMSS\&. If the argument begins with a \*(Aq+\*(Aq or \*(Aq\-\*(Aq, it is interpreted as an offset from the present time\&. For convenience, if such an offset is followed by one of the suffixes \*(Aqy\*(Aq, \*(Aqmo\*(Aq, \*(Aqw\*(Aq, \*(Aqd\*(Aq, \*(Aqh\*(Aq, or \*(Aqmi\*(Aq, then the offset is computed in years (defined as 365 24\-hour days, ignoring leap years), months (defined as 30 24\-hour days), weeks, days, hours, or minutes, respectively\&. Without a suffix, the offset is computed in seconds\&. To explicitly prevent a date from being set, use \*(Aqnone\*(Aq or \*(Aqnever\*(Aq\&.
+.PP
+\-P \fIdate/offset\fR
+.RS 4
+Sets the date on which a key is to be published to the zone\&. After that date, the key will be included in the zone but will not be used to sign it\&. If not set, and if the \-G option has not been used, the default is "now"\&.
+.RE
+.PP
+\-P sync \fIdate/offset\fR
+.RS 4
+Sets the date on which CDS and CDNSKEY records that match this key are to be published to the zone\&.
+.RE
+.PP
+\-A \fIdate/offset\fR
+.RS 4
+Sets the date on which the key is to be activated\&. After that date, the key will be included in the zone and used to sign it\&. If not set, and if the \-G option has not been used, the default is "now"\&. If set, if and \-P is not set, then the publication date will be set to the activation date minus the prepublication interval\&.
+.RE
+.PP
+\-R \fIdate/offset\fR
+.RS 4
+Sets the date on which the key is to be revoked\&. After that date, the key will be flagged as revoked\&. It will be included in the zone and will be used to sign it\&.
+.RE
+.PP
+\-I \fIdate/offset\fR
+.RS 4
+Sets the date on which the key is to be retired\&. After that date, the key will still be included in the zone, but it will not be used to sign it\&.
+.RE
+.PP
+\-D \fIdate/offset\fR
+.RS 4
+Sets the date on which the key is to be deleted\&. After that date, the key will no longer be included in the zone\&. (It may remain in the key repository, however\&.)
+.RE
+.PP
+\-D sync \fIdate/offset\fR
+.RS 4
+Sets the date on which the CDS and CDNSKEY records that match this key are to be deleted\&.
+.RE
+.PP
+\-i \fIinterval\fR
+.RS 4
+Sets the prepublication interval for a key\&. If set, then the publication and activation dates must be separated by at least this much time\&. If the activation date is specified but the publication date isn\*(Aqt, then the publication date will default to this much time before the activation date; conversely, if the publication date is specified but activation date isn\*(Aqt, then activation will be set to this much time after publication\&.
+.sp
+If the key is being created as an explicit successor to another key, then the default prepublication interval is 30 days; otherwise it is zero\&.
+.sp
+As with date offsets, if the argument is followed by one of the suffixes \*(Aqy\*(Aq, \*(Aqmo\*(Aq, \*(Aqw\*(Aq, \*(Aqd\*(Aq, \*(Aqh\*(Aq, or \*(Aqmi\*(Aq, then the interval is measured in years, months, weeks, days, hours, or minutes, respectively\&. Without a suffix, the interval is measured in seconds\&.

+\fBexample\&.com\fR, the following command would be issued:
+.PP
+\fBdnssec\-keygen \-a DSA \-b 768 \-n ZONE example\&.com\fR

+      generates keys for DNSSEC (Secure DNS), as defined in RFC 2535

+      TSIG (Transaction Signatures) as defined in RFC 2845, or TKEY
+      (Transaction Key) as defined in RFC 2930.
+    </para>
+    <para>
+      The <option>name</option> of the key is specified on the command
+      line.  For DNSSEC keys, this must match the name of the zone for

+	<listitem>
+	  <para>
+	    Selects the cryptographic algorithm.  For DNSSEC keys, the value
+	    of <option>algorithm</option> must be one of RSAMD5, RSASHA1,
+	    DSA, NSEC3RSASHA1, NSEC3DSA, RSASHA256, RSASHA512, ECCGOST,
+	    ECDSAP256SHA256, ECDSAP384SHA384, ED25519 or ED448.
+	    For TSIG/TKEY, the value must
+	    be DH (Diffie Hellman), HMAC-MD5, HMAC-SHA1, HMAC-SHA224,
+	    HMAC-SHA256, HMAC-SHA384, or HMAC-SHA512.  These values are
+	    case insensitive.
+	  </para>
+	  <para>
+	    If no algorithm is specified, then RSASHA1 will be used by
+	    default, unless the <option>-3</option> option is specified,
+	    in which case NSEC3RSASHA1 will be used instead.  (If
+	    <option>-3</option> is used and an algorithm is specified,
+	    that algorithm will be checked for compatibility with NSEC3.)
+	  </para>
+	  <para>
+	    Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement
+	    algorithm, and DSA is recommended.  For TSIG, HMAC-MD5 is
+	    mandatory.
+	  </para>
+	  <para>
+	    Note 2: DH, HMAC-MD5, and HMAC-SHA1 through HMAC-SHA512
+	    automatically set the -T KEY option.

+      <varlistentry>
+	<term>-b <replaceable class="parameter">keysize</replaceable></term>
+	<listitem>
+	  <para>
+	    Specifies the number of bits in the key.  The choice of key
+	    size depends on the algorithm used.  RSA keys must be
+	    between 512 and 2048 bits.  Diffie Hellman keys must be between
+	    128 and 4096 bits.  DSA keys must be between 512 and 1024
+	    bits and an exact multiple of 64.  HMAC keys must be
+	    between 1 and 512 bits. Elliptic curve algorithms don't need
+	    this parameter.
+	  </para>
+	  <para>
+	    The key size does not need to be specified if using a default
+	    algorithm.  The default key size is 1024 bits for zone signing
+	    keys (ZSKs) and 2048 bits for key signing keys (KSKs,
+	    generated with <option>-f KSK</option>).  However, if an
+	    algorithm is explicitly specified with the <option>-a</option>,
+	    then there is no default key size, and the <option>-b</option>
+	    must be used.

+	<listitem>
+	  <para>
+	    Specifies the owner type of the key.  The value of

+	    zone key (KEY/DNSKEY)), HOST or ENTITY (for a key associated with
+	    a host (KEY)),
+	    USER (for a key associated with a user(KEY)) or OTHER (DNSKEY).

+	    default. Note that RSASHA256, RSASHA512, ECCGOST,
+	    ECDSAP256SHA256, ECDSAP384SHA384, ED25519 and ED448
+	    algorithms are NSEC3-capable.

+
+    <p><span class="command"><strong>dnssec-keygen</strong></span>
+      generates keys for DNSSEC (Secure DNS), as defined in RFC 2535
+      and RFC 4034.  It can also generate keys for use with
+      TSIG (Transaction Signatures) as defined in RFC 2845, or TKEY
+      (Transaction Key) as defined in RFC 2930.
+    </p>
+    <p>
+      The <code class="option">name</code> of the key is specified on the command
+      line.  For DNSSEC keys, this must match the name of the zone for
+      which the key is being generated.
+    </p>
+  </div>
+
+  <div class="refsection">
+<a name="id-1.8"></a><h2>OPTIONS</h2>
+
+
+    <div class="variablelist"><dl class="variablelist">
+<dt><span class="term">-a <em class="replaceable"><code>algorithm</code></em></span></dt>
+<dd>
+	  <p>
+	    Selects the cryptographic algorithm.  For DNSSEC keys, the value
+	    of <code class="option">algorithm</code> must be one of RSAMD5, RSASHA1,
+	    DSA, NSEC3RSASHA1, NSEC3DSA, RSASHA256, RSASHA512, ECCGOST,
+	    ECDSAP256SHA256, ECDSAP384SHA384, ED25519 or ED448.
+	    For TSIG/TKEY, the value must
+	    be DH (Diffie Hellman), HMAC-MD5, HMAC-SHA1, HMAC-SHA224,
+	    HMAC-SHA256, HMAC-SHA384, or HMAC-SHA512.  These values are
+	    case insensitive.
+	  </p>
+	  <p>
+	    If no algorithm is specified, then RSASHA1 will be used by
+	    default, unless the <code class="option">-3</code> option is specified,
+	    in which case NSEC3RSASHA1 will be used instead.  (If
+	    <code class="option">-3</code> is used and an algorithm is specified,
+	    that algorithm will be checked for compatibility with NSEC3.)
+	  </p>
+	  <p>
+	    Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement
+	    algorithm, and DSA is recommended.  For TSIG, HMAC-MD5 is
+	    mandatory.
+	  </p>
+	  <p>
+	    Note 2: DH, HMAC-MD5, and HMAC-SHA1 through HMAC-SHA512
+	    automatically set the -T KEY option.
+	  </p>
+	</dd>
+<dt><span class="term">-b <em class="replaceable"><code>keysize</code></em></span></dt>
+<dd>
+	  <p>
+	    Specifies the number of bits in the key.  The choice of key
+	    size depends on the algorithm used.  RSA keys must be
+	    between 512 and 2048 bits.  Diffie Hellman keys must be between
+	    128 and 4096 bits.  DSA keys must be between 512 and 1024
+	    bits and an exact multiple of 64.  HMAC keys must be
+	    between 1 and 512 bits. Elliptic curve algorithms don't need
+	    this parameter.
+	  </p>
+	  <p>
+	    The key size does not need to be specified if using a default
+	    algorithm.  The default key size is 1024 bits for zone signing
+	    keys (ZSKs) and 2048 bits for key signing keys (KSKs,
+	    generated with <code class="option">-f KSK</code>).  However, if an
+	    algorithm is explicitly specified with the <code class="option">-a</code>,
+	    then there is no default key size, and the <code class="option">-b</code>
+	    must be used.
+	  </p>
+	</dd>
+<dt><span class="term">-n <em class="replaceable"><code>nametype</code></em></span></dt>
+<dd>
+	  <p>
+	    Specifies the owner type of the key.  The value of
+	    <code class="option">nametype</code> must either be ZONE (for a DNSSEC
+	    zone key (KEY/DNSKEY)), HOST or ENTITY (for a key associated with
+	    a host (KEY)),
+	    USER (for a key associated with a user(KEY)) or OTHER (DNSKEY).
+	    These values are case insensitive.  Defaults to ZONE for DNSKEY
+	    generation.
+	  </p>
+	</dd>
+<dt><span class="term">-3</span></dt>
+<dd>
+	  <p>
+	    Use an NSEC3-capable algorithm to generate a DNSSEC key.
+	    If this option is used and no algorithm is explicitly
+	    set on the command line, NSEC3RSASHA1 will be used by
+	    default. Note that RSASHA256, RSASHA512, ECCGOST,
+	    ECDSAP256SHA256, ECDSAP384SHA384, ED25519 and ED448
+	    algorithms are NSEC3-capable.

+	  <p>
+	    Compatibility mode:  generates an old-style key, without
+	    any metadata.  By default, <span class="command"><strong>dnssec-keygen</strong></span>
+	    will include the key's creation date in the metadata stored
+	    with the private key, and other dates may be set there as well
+	    (publication date, activation date, etc).  Keys that include
+	    this data may be incompatible with older versions of BIND; the
+	    <code class="option">-C</code> option suppresses them.

+	    When BIND is built with OpenSSL PKCS#11 support, this defaults
+	    to the string "pkcs11", which identifies an OpenSSL engine
+	    that can drive a cryptographic accelerator or hardware service
+	    module.  When BIND is built with native PKCS#11 cryptography
+	    (--enable-native-pkcs11), it defaults to the path of the PKCS#11

+      days, hours, or minutes, respectively.  Without a suffix, the offset

+.SH "DESCRIPTION"
+.PP
+\fBdnssec\-settime\fR
+reads a DNSSEC private key file and sets the key timing metadata as specified by the
+\fB\-P\fR,
+\fB\-A\fR,
+\fB\-R\fR,
+\fB\-I\fR, and
+\fB\-D\fR
+options\&. The metadata can then be used by
+\fBdnssec\-signzone\fR
+or other signing software to determine when a key is to be published, whether it should be used for signing a zone, etc\&.
+.PP
+If none of these options is set on the command line, then
+\fBdnssec\-settime\fR
+simply prints the key timing metadata already stored in the key\&.
+.PP
+When key metadata fields are changed, both files of a key pair (Knnnn\&.+aaa+iiiii\&.key
+and
+Knnnn\&.+aaa+iiiii\&.private) are regenerated\&. Metadata fields are stored in the private file\&. A human\-readable description of the metadata is also placed in comments in the key file\&. The private file\*(Aqs permissions are always set to be inaccessible to anyone other than the owner (mode 0600)\&.
+.SH "OPTIONS"
+.PP
+\-f
+.RS 4
+Force an update of an old\-format key with no metadata fields\&. Without this option,
+\fBdnssec\-settime\fR
+will fail when attempting to update a legacy key\&. With this option, the key will be recreated in the new format, but with the original key data retained\&. The key\*(Aqs creation date will be set to the present time\&. If no other values are specified, then the key\*(Aqs publication and activation dates will also be set to the present time\&.
+.RE
+.PP
+\-K \fIdirectory\fR
+.RS 4
+Sets the directory in which the key files are to reside\&.
+.RE
+.PP
+\-L \fIttl\fR
+.RS 4
+Sets the default TTL to use for this key when it is converted into a DNSKEY RR\&. If the key is imported into a zone, this is the TTL that will be used for it, unless there was already a DNSKEY RRset in place, in which case the existing TTL would take precedence\&. If this value is not set and there is no existing DNSKEY RRset, the TTL will default to the SOA TTL\&. Setting the default TTL to
+0
+or
+none
+removes it from the key\&.
+.RE
+.PP
+\-h
+.RS 4
+Emit usage message and exit\&.
+.RE
+.PP
+\-V
+.RS 4
+Prints version information\&.
+.RE
+.PP
+\-v \fIlevel\fR
+.RS 4
+Sets the debugging level\&.
+.RE
+.PP
+\-E \fIengine\fR
+.RS 4
+Specifies the cryptographic hardware to use, when applicable\&.
+.sp
+When BIND is built with OpenSSL PKCS#11 support, this defaults to the string "pkcs11", which identifies an OpenSSL engine that can drive a cryptographic accelerator or hardware service module\&. When BIND is built with native PKCS#11 cryptography (\-\-enable\-native\-pkcs11), it defaults to the path of the PKCS#11 provider library specified via "\-\-with\-pkcs11"\&.
+.RE
+.SH "TIMING OPTIONS"
+.PP
+Dates can be expressed in the format YYYYMMDD or YYYYMMDDHHMMSS\&. If the argument begins with a \*(Aq+\*(Aq or \*(Aq\-\*(Aq, it is interpreted as an offset from the present time\&. For convenience, if such an offset is followed by one of the suffixes \*(Aqy\*(Aq, \*(Aqmo\*(Aq, \*(Aqw\*(Aq, \*(Aqd\*(Aq, \*(Aqh\*(Aq, or \*(Aqmi\*(Aq, then the offset is computed in years (defined as 365 24\-hour days, ignoring leap years), months (defined as 30 24\-hour days), weeks, days, hours, or minutes, respectively\&. Without a suffix, the offset is computed in seconds\&. To unset a date, use \*(Aqnone\*(Aq or \*(Aqnever\*(Aq\&.
+.PP
+\-P \fIdate/offset\fR
+.RS 4
+Sets the date on which a key is to be published to the zone\&. After that date, the key will be included in the zone but will not be used to sign it\&.
+.RE
+.PP
+\-P sync \fIdate/offset\fR
+.RS 4
+Sets the date on which CDS and CDNSKEY records that match this key are to be published to the zone\&.
+.RE
+.PP
+\-A \fIdate/offset\fR
+.RS 4
+Sets the date on which the key is to be activated\&. After that date, the key will be included in the zone and used to sign it\&.
+.RE
+.PP
+\-R \fIdate/offset\fR
+.RS 4
+Sets the date on which the key is to be revoked\&. After that date, the key will be flagged as revoked\&. It will be included in the zone and will be used to sign it\&.
+.RE
+.PP
+\-I \fIdate/offset\fR
+.RS 4
+Sets the date on which the key is to be retired\&. After that date, the key will still be included in the zone, but it will not be used to sign it\&.
+.RE
+.PP
+\-D \fIdate/offset\fR
+.RS 4
+Sets the date on which the key is to be deleted\&. After that date, the key will no longer be included in the zone\&. (It may remain in the key repository, however\&.)
+.RE
+.PP
+\-D sync \fIdate/offset\fR
+.RS 4
+Sets the date on which the CDS and CDNSKEY records that match this key are to be deleted\&.
+.RE
+.PP
+\-S \fIpredecessor key\fR
+.RS 4
+Select a key for which the key being modified will be an explicit successor\&. The name, algorithm, size, and type of the predecessor key must exactly match those of the key being modified\&. The activation date of the successor key will be set to the inactivation date of the predecessor\&. The publication date will be set to the activation date minus the prepublication interval, which defaults to 30 days\&.
+.RE
+.PP
+\-i \fIinterval\fR
+.RS 4
+Sets the prepublication interval for a key\&. If set, then the publication and activation dates must be separated by at least this much time\&. If the activation date is specified but the publication date isn\*(Aqt, then the publication date will default to this much time before the activation date; conversely, if the publication date is specified but activation date isn\*(Aqt, then activation will be set to this much time after publication\&.
+.sp
+If the key is being set to be an explicit successor to another key, then the default prepublication interval is 30 days; otherwise it is zero\&.
+.sp
+As with date offsets, if the argument is followed by one of the suffixes \*(Aqy\*(Aq, \*(Aqmo\*(Aq, \*(Aqw\*(Aq, \*(Aqd\*(Aq, \*(Aqh\*(Aq, or \*(Aqmi\*(Aq, then the interval is measured in years, months, weeks, days, hours, or minutes, respectively\&. Without a suffix, the interval is measured in seconds\&.
+.RE
+.SH "PRINTING OPTIONS"
+.PP
+\fBdnssec\-settime\fR
+can also be used to print the timing metadata associated with a key\&.
+.PP
+\-u
+.RS 4
+Print times in UNIX epoch format\&.
+.RE
+.PP
+\-p \fIC/P/Psync/A/R/I/D/Dsync/all\fR
+.RS 4
+Print a specific metadata value or set of metadata values\&. The
+\fB\-p\fR
+option may be followed by one or more of the following letters or strings to indicate which value or values to print:
+\fBC\fR
+for the creation date,

+    <para><command>dnssec-settime</command>
+      reads a DNSSEC private key file and sets the key timing metadata
+      as specified by the <option>-P</option>, <option>-A</option>,
+      <option>-R</option>, <option>-I</option>, and <option>-D</option>
+      options.  The metadata can then be used by
+      <command>dnssec-signzone</command> or other signing software to
+      determine when a key is to be published, whether it should be
+      used for signing a zone, etc.
+    </para>
+    <para>
+      If none of these options is set on the command line,
+      then <command>dnssec-settime</command> simply prints the key timing
+      metadata already stored in the key.
+    </para>
+    <para>
+      When key metadata fields are changed, both files of a key
+      pair (<filename>Knnnn.+aaa+iiiii.key</filename> and
+      <filename>Knnnn.+aaa+iiiii.private</filename>) are regenerated.
+      Metadata fields are stored in the private file.  A human-readable
+      description of the metadata is also placed in comments in the key
+      file.  The private file's permissions are always set to be
+      inaccessible to anyone other than the owner (mode 0600).

+            Without this option, <command>dnssec-settime</command> will

+            the key will be recreated in the new format, but with the
+            original key data retained.  The key's creation date will be
+            set to the present time.  If no other values are specified,
+            then the key's publication and activation dates will also
+            be set to the present time.

+
+    <p><span class="command"><strong>dnssec-settime</strong></span>
+      reads a DNSSEC private key file and sets the key timing metadata
+      as specified by the <code class="option">-P</code>, <code class="option">-A</code>,
+      <code class="option">-R</code>, <code class="option">-I</code>, and <code class="option">-D</code>
+      options.  The metadata can then be used by
+      <span class="command"><strong>dnssec-signzone</strong></span> or other signing software to
+      determine when a key is to be published, whether it should be
+      used for signing a zone, etc.
+    </p>
+    <p>
+      If none of these options is set on the command line,
+      then <span class="command"><strong>dnssec-settime</strong></span> simply prints the key timing
+      metadata already stored in the key.
+    </p>
+    <p>
+      When key metadata fields are changed, both files of a key
+      pair (<code class="filename">Knnnn.+aaa+iiiii.key</code> and
+      <code class="filename">Knnnn.+aaa+iiiii.private</code>) are regenerated.
+      Metadata fields are stored in the private file.  A human-readable
+      description of the metadata is also placed in comments in the key
+      file.  The private file's permissions are always set to be
+      inaccessible to anyone other than the owner (mode 0600).

+.SH "DESCRIPTION"
+.PP
+\fBdnssec\-signzone\fR
+signs a zone\&. It generates NSEC and RRSIG records and produces a signed version of the zone\&. The security status of delegations from the signed zone (that is, whether the child zones are secure or not) is determined by the presence or absence of a
+keyset
+file for each child zone\&.
+.SH "OPTIONS"
+.PP
+\-a
+.RS 4
+Verify all generated signatures\&.
+.RE
+.PP
+\-c \fIclass\fR
+.RS 4
+Specifies the DNS class of the zone\&.
+.RE
+.PP
+\-C
+.RS 4
+Compatibility mode: Generate a
+keyset\-\fIzonename\fR
+file in addition to
+dsset\-\fIzonename\fR
+when signing a zone, for use by older versions of
+\fBdnssec\-signzone\fR\&.
+.RE
+.PP
+\-d \fIdirectory\fR
+.RS 4
+Look for
+dsset\-
+or
+keyset\-
+files in
+\fBdirectory\fR\&.
+.RE
+.PP
+\-D
+.RS 4
+Output only those record types automatically managed by
+\fBdnssec\-signzone\fR, i\&.e\&. RRSIG, NSEC, NSEC3 and NSEC3PARAM records\&. If smart signing (\fB\-S\fR) is used, DNSKEY records are also included\&. The resulting file can be included in the original zone file with
+\fB$INCLUDE\fR\&. This option cannot be combined with
+\fB\-O raw\fR,
+\fB\-O map\fR, or serial number updating\&.
+.RE
+.PP
+\-E \fIengine\fR
+.RS 4
+When applicable, specifies the hardware to use for cryptographic operations, such as a secure key store used for signing\&.
+.sp
+When BIND is built with OpenSSL PKCS#11 support, this defaults to the string "pkcs11", which identifies an OpenSSL engine that can drive a cryptographic accelerator or hardware service module\&. When BIND is built with native PKCS#11 cryptography (\-\-enable\-native\-pkcs11), it defaults to the path of the PKCS#11 provider library specified via "\-\-with\-pkcs11"\&.
+.RE
+.PP
+\-g
+.RS 4
+Generate DS records for child zones from
+dsset\-
+or
+keyset\-
+file\&. Existing DS records will be removed\&.
+.RE
+.PP
+\-K \fIdirectory\fR
+.RS 4
+Key repository: Specify a directory to search for DNSSEC keys\&. If not specified, defaults to the current directory\&.
+.RE
+.PP
+\-k \fIkey\fR
+.RS 4
+Treat specified key as a key signing key ignoring any key flags\&. This option may be specified multiple times\&.
+.RE
+.PP
+\-l \fIdomain\fR
+.RS 4
+Generate a DLV set in addition to the key (DNSKEY) and DS sets\&. The domain is appended to the name of the records\&.
+.RE
+.PP
+\-M \fImaxttl\fR
+.RS 4
+Sets the maximum TTL for the signed zone\&. Any TTL higher than
+\fImaxttl\fR
+in the input zone will be reduced to
+\fImaxttl\fR
+in the output\&. This provides certainty as to the largest possible TTL in the signed zone, which is useful to know when rolling keys because it is the longest possible time before signatures that have been retrieved by resolvers will expire from resolver caches\&. Zones that are signed with this option should be configured to use a matching
+\fBmax\-zone\-ttl\fR
+in
+named\&.conf\&. (Note: This option is incompatible with
+\fB\-D\fR, because it modifies non\-DNSSEC data in the output zone\&.)
+.RE
+.PP
+\-s \fIstart\-time\fR
+.RS 4
+Specify the date and time when the generated RRSIG records become valid\&. This can be either an absolute or relative time\&. An absolute start time is indicated by a number in YYYYMMDDHHMMSS notation; 20000530144500 denotes 14:45:00 UTC on May 30th, 2000\&. A relative start time is indicated by +N, which is N seconds from the current time\&. If no
+\fBstart\-time\fR
+is specified, the current time minus 1 hour (to allow for clock skew) is used\&.
+.RE
+.PP
+\-e \fIend\-time\fR
+.RS 4
+Specify the date and time when the generated RRSIG records expire\&. As with
+\fBstart\-time\fR, an absolute time is indicated in YYYYMMDDHHMMSS notation\&. A time relative to the start time is indicated with +N, which is N seconds from the start time\&. A time relative to the current time is indicated with now+N\&. If no
+\fBend\-time\fR
+is specified, 30 days from the start time is used as a default\&.
+\fBend\-time\fR
+must be later than
+\fBstart\-time\fR\&.
+.RE
+.PP
+\-X \fIextended end\-time\fR
+.RS 4
+Specify the date and time when the generated RRSIG records for the DNSKEY RRset will expire\&. This is to be used in cases when the DNSKEY signatures need to persist longer than signatures on other records; e\&.g\&., when the private component of the KSK is kept offline and the KSK signature is to be refreshed manually\&.
+.sp
+As with
+\fBstart\-time\fR, an absolute time is indicated in YYYYMMDDHHMMSS notation\&. A time relative to the start time is indicated with +N, which is N seconds from the start time\&. A time relative to the current time is indicated with now+N\&. If no
+\fBextended end\-time\fR
+is specified, the value of
+\fBend\-time\fR
+is used as the default\&. (\fBend\-time\fR, in turn, defaults to 30 days from the start time\&.)
+\fBextended end\-time\fR
+must be later than
+\fBstart\-time\fR\&.
+.RE
+.PP
+\-f \fIoutput\-file\fR
+.RS 4
+The name of the output file containing the signed zone\&. The default is to append
+\&.signed
+to the input filename\&. If
+\fBoutput\-file\fR
+is set to
+"\-", then the signed zone is written to the standard output, with a default output format of "full"\&.
+.RE
+.PP
+\-h
+.RS 4
+Prints a short summary of the options and arguments to
+\fBdnssec\-signzone\fR\&.
+.RE
+.PP
+\-V
+.RS 4
+Prints version information\&.
+.RE
+.PP
+\-i \fIinterval\fR
+.RS 4
+When a previously\-signed zone is passed as input, records may be resigned\&. The
+\fBinterval\fR

+The default cycle interval is one quarter of the difference between the signature end and start times\&. So if neither

+\fBdnssec\-signzone\fR

+\-j \fIjitter\fR
+.RS 4
+When signing a zone with a fixed signature lifetime, all RRSIG records issued at the time of signing expires simultaneously\&. If the zone is incrementally signed, i\&.e\&. a previously\-signed zone is passed as input to the signer, all expired signatures have to be regenerated at about the same time\&. The

+option specifies a jitter window that will be used to randomize the signature expire time, thus spreading incremental signature regeneration over time\&.
+.sp
+Signature lifetime jitter also to some extent benefits validators and servers by spreading out cache expiration, i\&.e\&. if large numbers of RRSIGs don\*(Aqt expire at the same time from all caches there will be less congestion than if all validators need to refetch at mostly the same time\&.

+      signs a zone.  It generates

+      (that is, whether the child zones are secure or not) is

+      <code class="filename">keyset</code> file for each child zone.

+

+      The following command signs the <strong class="userinput"><code>example.com</code></strong>
+      zone with the DSA key generated by <span class="command"><strong>dnssec-keygen</strong></span>
+      (Kexample.com.+003+17247).  Because the <span class="command"><strong>-S</strong></span> option
+      is not being used, the zone's keys must be in the master file
+      (<code class="filename">db.example.com</code>).  This invocation looks
+      for <code class="filename">dsset</code> files, in the current directory,
+      so that DS records can be imported from them (<span class="command"><strong>-g</strong></span>).
+    </p>
+<pre class="programlisting">% dnssec-signzone -g -o example.com db.example.com \
+Kexample.com.+003+17247
+db.example.com.signed
+%</pre>
+    <p>
+      In the above example, <span class="command"><strong>dnssec-signzone</strong></span> creates
+      the file <code class="filename">db.example.com.signed</code>.  This

+.SH "DESCRIPTION"
+.PP
+\fBdnssec\-verify\fR
+verifies that a zone is fully signed for each algorithm found in the DNSKEY RRset for the zone, and that the NSEC / NSEC3 chains are complete\&.
+.SH "OPTIONS"
+.PP
+\-c \fIclass\fR
+.RS 4
+Specifies the DNS class of the zone\&.
+.RE
+.PP
+\-E \fIengine\fR
+.RS 4
+Specifies the cryptographic hardware to use, when applicable\&.
+.sp
+When BIND is built with OpenSSL PKCS#11 support, this defaults to the string "pkcs11", which identifies an OpenSSL engine that can drive a cryptographic accelerator or hardware service module\&. When BIND is built with native PKCS#11 cryptography (\-\-enable\-native\-pkcs11), it defaults to the path of the PKCS#11 provider library specified via "\-\-with\-pkcs11"\&.
+.RE
+.PP
+\-I \fIinput\-format\fR
+.RS 4
+The format of the input zone file\&. Possible formats are
+\fB"text"\fR
+(default) and
+\fB"raw"\fR\&. This option is primarily intended to be used for dynamic signed zones so that the dumped zone file in a non\-text format containing updates can be verified independently\&. The use of this option does not make much sense for non\-dynamic zones\&.
+.RE
+.PP
+\-o \fIorigin\fR
+.RS 4
+The zone origin\&. If not specified, the name of the zone file is assumed to be the origin\&.
+.RE
+.PP
+\-v \fIlevel\fR
+.RS 4
+Sets the debugging level\&.
+.RE
+.PP
+\-V
+.RS 4
+Prints version information\&.
+.RE
+.PP
+\-x
+.RS 4
+Only verify that the DNSKEY RRset is signed with key\-signing keys\&. Without this flag, it is assumed that the DNSKEY RRset will be signed by all active keys\&. When this flag is set, it will not be an error if the DNSKEY RRset is not signed by zone\-signing keys\&. This corresponds to the
+\fB\-x\fR
+option in
+\fBdnssec\-signzone\fR\&.
+.RE
+.PP
+\-z
+.RS 4
+Ignore the KSK flag on the keys when determining whether the zone if correctly signed\&. Without this flag it is assumed that there will be a non\-revoked, self\-signed DNSKEY with the KSK flag set for each algorithm and that RRsets other than DNSKEY RRset will be signed with a different DNSKEY without the KSK flag set\&.
+.sp
+With this flag set, we only require that for each algorithm, there will be at least one non\-revoked, self\-signed DNSKEY, regardless of the KSK flag state, and that other RRsets will be signed by a non\-revoked key for the same algorithm that includes the self\-signed key; the same key may be used for both purposes\&. This corresponds to the
+\fB\-z\fR
+option in
+\fBdnssec\-signzone\fR\&.
+.RE
+.PP
+zonefile
+.RS 4
+The file containing the zone to be signed\&.

+/*****
+ ***** Module Info
+ *****/
+
+/*! \file
+ * \brief
+ * This module defines two objects, ns_client_t and ns_clientmgr_t.
+ *
+ * An ns_client_t object handles incoming DNS requests from clients
+ * on a given network interface.
+ *
+ * Each ns_client_t object can handle only one TCP connection or UDP
+ * request at a time.  Therefore, several ns_client_t objects are
+ * typically created to serve each network interface, e.g., one
+ * for handling TCP requests and a few (one per CPU) for handling
+ * UDP requests.
+ *
+ * Incoming requests are classified as queries, zone transfer
+ * requests, update requests, notify requests, etc, and handed off
+ * to the appropriate request handler.  When the request has been
+ * fully handled (which can be much later), the ns_client_t must be
+ * notified of this by calling one of the following functions
+ * exactly once in the context of its task:
+ * \code
+ *   ns_client_send()	(sending a non-error response)
+ *   ns_client_sendraw() (sending a raw response)
+ *   ns_client_error()	(sending an error response)
+ *   ns_client_next()	(sending no response)
+ *\endcode
+ * This will release any resources used by the request and
+ * and allow the ns_client_t to listen for the next request.
+ *
+ * A ns_clientmgr_t manages a number of ns_client_t objects.
+ * New ns_client_t objects are created by calling
+ * ns_clientmgr_createclients(). They are destroyed by
+ * destroying their manager.

+.SH "DESCRIPTION"
+.PP
+\fBlwresd\fR
+is the daemon providing name lookup services to clients that use the BIND 9 lightweight resolver library\&. It is essentially a stripped\-down, caching\-only name server that answers queries using the BIND 9 lightweight resolver protocol rather than the DNS protocol\&.
+.PP
+\fBlwresd\fR
+listens for resolver queries on a UDP port on the IPv4 loopback interface, 127\&.0\&.0\&.1\&. This means that
+\fBlwresd\fR
+can only be used by processes running on the local machine\&. By default, UDP port number 921 is used for lightweight resolver requests and responses\&.
+.PP
+Incoming lightweight resolver requests are decoded by the server which then resolves them using the DNS protocol\&. When the DNS lookup completes,
+\fBlwresd\fR
+encodes the answers in the lightweight resolver format and returns them to the client that made the request\&.
+.PP
+If
+/etc/resolv\&.conf
+contains any
+\fBnameserver\fR
+entries,
+\fBlwresd\fR
+sends recursive DNS queries to those servers\&. This is similar to the use of forwarders in a caching name server\&. If no
+\fBnameserver\fR
+entries are present, or if forwarding fails,
+\fBlwresd\fR
+resolves the queries autonomously starting at the root name servers, using a built\-in list of root server hints\&.
+.SH "OPTIONS"
+.PP

+Use IPv4 only even if the host machine is capable of IPv6\&.

+Turn on memory usage debugging flags\&. Possible flags are
+\fIusage\fR,
+\fItrace\fR,
+\fIrecord\fR,
+\fIsize\fR, and
+\fImctx\fR\&. These correspond to the ISC_MEM_DEBUGXXXX flags described in
+<isc/mem\&.h>\&.
+.RE
+.PP
+\-n \fI#cpus\fR
+.RS 4
+Create
+\fI#cpus\fR
+worker threads to take advantage of multiple CPUs\&. If not specified,
+\fBlwresd\fR
+will try to determine the number of CPUs present and create one thread per CPU\&. If it is unable to determine the number of CPUs, a single worker thread will be created\&.

+Listen for lightweight resolver queries on port
+\fIport\fR\&. If not specified, the default is port 921\&.
+.RE
+.PP
+\-p \fIport\fR
+.RS 4
+Send DNS lookups to port
+\fIport\fR\&. If not specified, the default is port 53\&. This provides a way of testing the lightweight resolver daemon with a name server that listens for queries on a non\-standard port number\&.

+
+    <para><command>lwresd</command>
+      is the daemon providing name lookup
+      services to clients that use the BIND 9 lightweight resolver
+      library.  It is essentially a stripped-down, caching-only name
+      server that answers queries using the BIND 9 lightweight
+      resolver protocol rather than the DNS protocol.
+    </para>
+
+    <para><command>lwresd</command>
+      listens for resolver queries on a
+      UDP port on the IPv4 loopback interface, 127.0.0.1.  This
+      means that <command>lwresd</command> can only be used by
+      processes running on the local machine.  By default, UDP port
+      number 921 is used for lightweight resolver requests and
+      responses.
+    </para>
+    <para>
+      Incoming lightweight resolver requests are decoded by the
+      server which then resolves them using the DNS protocol.  When
+      the DNS lookup completes, <command>lwresd</command> encodes
+      the answers in the lightweight resolver format and returns
+      them to the client that made the request.
+    </para>
+    <para>
+      If <filename>/etc/resolv.conf</filename> contains any
+      <option>nameserver</option> entries, <command>lwresd</command>
+      sends recursive DNS queries to those servers.  This is similar
+      to the use of forwarders in a caching name server.  If no
+      <option>nameserver</option> entries are present, or if
+      forwarding fails, <command>lwresd</command> resolves the
+      queries autonomously starting at the root name servers, using
+      a built-in list of root server hints.

+
+
+    <p><span class="command"><strong>lwresd</strong></span>
+      is the daemon providing name lookup
+      services to clients that use the BIND 9 lightweight resolver
+      library.  It is essentially a stripped-down, caching-only name
+      server that answers queries using the BIND 9 lightweight
+      resolver protocol rather than the DNS protocol.
+    </p>
+
+    <p><span class="command"><strong>lwresd</strong></span>
+      listens for resolver queries on a
+      UDP port on the IPv4 loopback interface, 127.0.0.1.  This
+      means that <span class="command"><strong>lwresd</strong></span> can only be used by
+      processes running on the local machine.  By default, UDP port
+      number 921 is used for lightweight resolver requests and
+      responses.
+    </p>
+    <p>
+      Incoming lightweight resolver requests are decoded by the
+      server which then resolves them using the DNS protocol.  When
+      the DNS lookup completes, <span class="command"><strong>lwresd</strong></span> encodes
+      the answers in the lightweight resolver format and returns
+      them to the client that made the request.
+    </p>
+    <p>
+      If <code class="filename">/etc/resolv.conf</code> contains any
+      <code class="option">nameserver</code> entries, <span class="command"><strong>lwresd</strong></span>
+      sends recursive DNS queries to those servers.  This is similar
+      to the use of forwarders in a caching name server.  If no
+      <code class="option">nameserver</code> entries are present, or if
+      forwarding fails, <span class="command"><strong>lwresd</strong></span> resolves the
+      queries autonomously starting at the root name servers, using
+      a built-in list of root server hints.
+    </p>

+.SH "DESCRIPTION"
+.PP
+\fBnamed\fR
+is a Domain Name System (DNS) server, part of the BIND 9 distribution from ISC\&. For more information on the DNS, see RFCs 1033, 1034, and 1035\&.
+.PP
+When invoked without arguments,
+\fBnamed\fR
+will read the default configuration file
+/etc/named\&.conf, read any initial data, and listen for queries\&.
+.SH "OPTIONS"
+.PP

+.RS 4
+Use IPv4 only even if the host machine is capable of IPv6\&.

+.RE
+.PP
+\-c \fIconfig\-file\fR
+.RS 4
+Use
+\fIconfig\-file\fR
+as the configuration file instead of the default,
+/etc/named\&.conf\&. To ensure that reloading the configuration file continues to work after the server has changed its working directory due to to a possible
+\fBdirectory\fR
+option in the configuration file,
+\fIconfig\-file\fR
+should be an absolute pathname\&.
+.RE
+.PP
+\-d \fIdebug\-level\fR
+.RS 4
+Set the daemon\*(Aqs debug level to
+\fIdebug\-level\fR\&. Debugging traces from
+\fBnamed\fR
+become more verbose as the debug level increases\&.
+.RE
+.PP
+\-D \fIstring\fR
+.RS 4
+Specifies a string that is used to identify a instance of
+\fBnamed\fR
+in a process listing\&. The contents of
+\fIstring\fR
+are not examined\&.
+.RE
+.PP
+\-E \fIengine\-name\fR
+.RS 4
+When applicable, specifies the hardware to use for cryptographic operations, such as a secure key store used for signing\&.
+.sp
+When BIND is built with OpenSSL PKCS#11 support, this defaults to the string "pkcs11", which identifies an OpenSSL engine that can drive a cryptographic accelerator or hardware service module\&. When BIND is built with native PKCS#11 cryptography (\-\-enable\-native\-pkcs11), it defaults to the path of the PKCS#11 provider library specified via "\-\-with\-pkcs11"\&.
+.RE
+.PP
+\-f
+.RS 4
+Run the server in the foreground (i\&.e\&. do not daemonize)\&.

+\fBlogfile\fR
+by default instead of the system log\&.
+.RE
+.PP
+\-M \fIoption\fR
+.RS 4
+Sets the default memory context options\&. Currently the only supported option is
+\fIexternal\fR, which causes the internal memory manager to be bypassed in favor of system\-provided memory allocation functions\&.
+.RE
+.PP
+\-m \fIflag\fR
+.RS 4
+Turn on memory usage debugging flags\&. Possible flags are
+\fIusage\fR,
+\fItrace\fR,
+\fIrecord\fR,

+\fImctx\fR\&. These correspond to the ISC_MEM_DEBUGXXXX flags described in
+<isc/mem\&.h>\&.

+\-n \fI#cpus\fR
+.RS 4
+Create
+\fI#cpus\fR
+worker threads to take advantage of multiple CPUs\&. If not specified,
+\fBnamed\fR
+will try to determine the number of CPUs present and create one thread per CPU\&. If it is unable to determine the number of CPUs, a single worker thread will be created\&.

+\-S \fI#max\-socks\fR
+.RS 4
+Allow
+\fBnamed\fR

+\fBWarning\fR
+.ps -1
+.br
+This option should be unnecessary for the vast majority of users\&. The use of this option could even be harmful because the specified value may exceed the limitation of the underlying system API\&. It is therefore set only when the default configuration causes exhaustion of file descriptors and the operational environment is known to support the specified number of sockets\&. Note also that the actual maximum number is normally a little fewer than the specified value because

+              This option should be unnecessary for the vast majority
+              of users.
+              The use of this option could even be harmful because the
+              specified value may exceed the limitation of the
+              underlying system API.
+              It is therefore set only when the default configuration
+              causes exhaustion of file descriptors and the
+              operational environment is known to support the
+              specified number of sockets.
+              Note also that the actual maximum number is normally a little
+              fewer than the specified value because
+              <span class="command"><strong>named</strong></span> reserves some file descriptors

+.SH "DESCRIPTION"
+.PP
+\fBnsupdate\fR
+is used to submit Dynamic DNS Update requests as defined in RFC 2136 to a name server\&. This allows resource records to be added or removed from a zone without manually editing the zone file\&. A single update request can contain requests to add or remove more than one resource record\&.
+.PP
+Zones that are under dynamic control via
+\fBnsupdate\fR
+or a DHCP server should not be edited by hand\&. Manual edits could conflict with dynamic updates and cause data to be lost\&.
+.PP
+The resource records that are dynamically added or removed with
+\fBnsupdate\fR
+have to be in the same zone\&. Requests are sent to the zone\*(Aqs master server\&. This is identified by the MNAME field of the zone\*(Aqs SOA record\&.
+.PP
+Transaction signatures can be used to authenticate the Dynamic DNS updates\&. These use the TSIG resource record type described in RFC 2845 or the SIG(0) record described in RFC 2535 and RFC 2931 or GSS\-TSIG as described in RFC 3645\&.
+.PP
+TSIG relies on a shared secret that should only be known to
+\fBnsupdate\fR
+and the name server\&. For instance, suitable
+\fBkey\fR
+and
+\fBserver\fR
+statements would be added to
+/etc/named\&.conf
+so that the name server can associate the appropriate secret key and algorithm with the IP address of the client application that will be using TSIG authentication\&. You can use
+\fBddns\-confgen\fR
+to generate suitable configuration fragments\&.
+\fBnsupdate\fR
+uses the
+\fB\-y\fR
+or
+\fB\-k\fR
+options to provide the TSIG shared secret\&. These options are mutually exclusive\&.
+.PP
+SIG(0) uses public key cryptography\&. To use a SIG(0) key, the public key must be stored in a KEY record in a zone served by the name server\&.
+.PP
+GSS\-TSIG uses Kerberos credentials\&. Standard GSS\-TSIG mode is switched on with the
+\fB\-g\fR
+flag\&. A non\-standards\-compliant variant of GSS\-TSIG used by Windows 2000 can be switched on with the
+\fB\-o\fR
+flag\&.
+.SH "OPTIONS"
+.PP
+\-d
+.RS 4
+Debug mode\&. This provides tracing information about the update requests that are made and the replies received from the name server\&.
+.RE
+.PP
+\-D
+.RS 4
+Extra debug mode\&.
+.RE
+.PP
+\-i
+.RS 4
+Force interactive mode, even when standard input is not a terminal\&.
+.RE
+.PP
+\-k \fIkeyfile\fR
+.RS 4
+The file containing the TSIG authentication key\&. Keyfiles may be in two formats: a single file containing a
+named\&.conf\-format
+\fBkey\fR
+statement, which may be generated automatically by
+\fBddns\-confgen\fR, or a pair of files whose names are of the format
+K{name}\&.+157\&.+{random}\&.key
+and
+K{name}\&.+157\&.+{random}\&.private, which can be generated by
+\fBdnssec\-keygen\fR\&. The
+\fB\-k\fR
+may also be used to specify a SIG(0) key used to authenticate Dynamic DNS update requests\&. In this case, the key specified is not an HMAC\-MD5 key\&.
+.RE
+.PP
+\-l
+.RS 4
+Local\-host only mode\&. This sets the server address to localhost (disabling the
+\fBserver\fR
+so that the server address cannot be overridden)\&. Connections to the local server will use a TSIG key found in
+/var/run/named/session\&.key, which is automatically generated by
+\fBnamed\fR
+if any local master zone has set
+\fBupdate\-policy\fR
+to
+\fBlocal\fR\&. The location of this key file can be overridden with the
+\fB\-k\fR
+option\&.
+.RE
+.PP
+\-L \fIlevel\fR
+.RS 4
+Set the logging debug level\&. If zero, logging is disabled\&.
+.RE
+.PP
+\-p \fIport\fR
+.RS 4
+Set the port to use for connections to a name server\&. The default is 53\&.
+.RE
+.PP
+\-P
+.RS 4
+Print the list of private BIND\-specific resource record types whose format is understood by
+\fBnsupdate\fR\&. See also the
+\fB\-T\fR
+option\&.
+.RE
+.PP
+\-r \fIudpretries\fR
+.RS 4
+The number of UDP retries\&. The default is 3\&. If zero, only one update request will be made\&.
+.RE
+.PP
+\-R \fIrandomdev\fR
+.RS 4
+Where to obtain randomness\&. If the operating system does not provide a
+/dev/random
+or equivalent device, the default source of randomness is keyboard input\&.
+randomdev
+specifies the name of a character device or file containing random data to be used instead of the default\&. The special value
+keyboard
+indicates that keyboard input should be used\&. This option may be specified multiple times\&.
+.RE
+.PP
+\-t \fItimeout\fR
+.RS 4
+The maximum time an update request can take before it is aborted\&. The default is 300 seconds\&. Zero can be used to disable the timeout\&.
+.RE
+.PP
+\-T
+.RS 4
+Print the list of IANA standard resource record types whose format is understood by
+\fBnsupdate\fR\&.
+\fBnsupdate\fR
+will exit after the lists are printed\&. The
+\fB\-T\fR
+option can be combined with the
+\fB\-P\fR
+option\&.
+.sp
+Other types can be entered using "TYPEXXXXX" where "XXXXX" is the decimal value of the type with no leading zeros\&. The rdata, if present, will be parsed using the UNKNOWN rdata format, (<backslash> <hash> <space> <length> <space> <hexstring>)\&.
+.RE
+.PP
+\-u \fIudptimeout\fR
+.RS 4
+The UDP retry interval\&. The default is 3 seconds\&. If zero, the interval will be computed from the timeout interval and number of UDP retries\&.
+.RE
+.PP
+\-v
+.RS 4
+Use TCP even for small update requests\&. By default,
+\fBnsupdate\fR
+uses UDP to send update requests to the name server unless they are too large to fit in a UDP request in which case TCP will be used\&. TCP may be preferable when a batch of update requests is made\&.
+.RE
+.PP
+\-V
+.RS 4
+Print the version number and exit\&.
+.RE
+.PP
+\-y \fI[hmac:]\fR\fIkeyname:secret\fR
+.RS 4
+Literal TSIG authentication key\&.
+\fIkeyname\fR
+is the name of the key, and
+\fIsecret\fR
+is the base64 encoded shared secret\&.
+\fIhmac\fR
+is the name of the key algorithm; valid choices are
+hmac\-md5,
+hmac\-sha1,
+hmac\-sha224,
+hmac\-sha256,
+hmac\-sha384, or
+hmac\-sha512\&. If
+\fIhmac\fR
+is not specified, the default is
+hmac\-md5
+or if MD5 was disabled
+hmac\-sha256\&.
+.sp
+NOTE: Use of the
+\fB\-y\fR
+option is discouraged because the shared secret is supplied as a command line argument in clear text\&. This may be visible in the output from
+\fBps\fR(1)
+or in a history file maintained by the user\*(Aqs shell\&.
+.RE
+.SH "INPUT FORMAT"
+.PP
+\fBnsupdate\fR
+reads input from
+\fIfilename\fR
+or standard input\&. Each command is supplied on exactly one line of input\&. Some commands are for administrative purposes\&. The others are either update instructions or prerequisite checks on the contents of the zone\&. These checks set conditions that some name or set of resource records (RRset) either exists or is absent from the zone\&. These conditions must be met if the entire update request is to succeed\&. Updates will be rejected if the tests for the prerequisite conditions fail\&.
+.PP
+Every update request consists of zero or more prerequisites and zero or more updates\&. This allows a suitably authenticated update request to proceed if some specified resource records are present or missing from the zone\&. A blank input line (or the
+\fBsend\fR
+command) causes the accumulated commands to be sent as one Dynamic DNS update request to the name server\&.
+.PP
+The command formats and their meaning are as follows:
+.PP
+\fBserver\fR {servername} [port]
+.RS 4
+Sends all dynamic update requests to the name server
+\fIservername\fR\&. When no server statement is provided,
+\fBnsupdate\fR
+will send updates to the master server of the correct zone\&. The MNAME field of that zone\*(Aqs SOA record will identify the master server for that zone\&.
+\fIport\fR
+is the port number on
+\fIservername\fR
+where the dynamic update requests get sent\&. If no port number is specified, the default DNS port number of 53 is used\&.
+.RE
+.PP
+\fBlocal\fR {address} [port]
+.RS 4
+Sends all dynamic update requests using the local
+\fIaddress\fR\&. When no local statement is provided,
+\fBnsupdate\fR
+will send updates using an address and port chosen by the system\&.
+\fIport\fR
+can additionally be used to make requests come from a specific port\&. If no port number is specified, the system will assign one\&.
+.RE
+.PP
+\fBzone\fR {zonename}
+.RS 4
+Specifies that all updates are to be made to the zone
+\fIzonename\fR\&. If no
+\fIzone\fR
+statement is provided,
+\fBnsupdate\fR
+will attempt determine the correct zone to update based on the rest of the input\&.
+.RE
+.PP
+\fBclass\fR {classname}
+.RS 4
+Specify the default class\&. If no
+\fIclass\fR
+is specified, the default class is
+\fIIN\fR\&.
+.RE
+.PP
+\fBttl\fR {seconds}
+.RS 4
+Specify the default time to live for records to be added\&. The value
+\fInone\fR
+will clear the default ttl\&.
+.RE
+.PP
+\fBkey\fR [hmac:] {keyname} {secret}
+.RS 4
+Specifies that all updates are to be TSIG\-signed using the
+\fIkeyname\fR\fIsecret\fR
+pair\&. If
+\fIhmac\fR
+is specified, then it sets the signing algorithm in use; the default is
+hmac\-md5
+or if MD5 was disabled
+hmac\-sha256\&. The
+\fBkey\fR
+command overrides any key specified on the command line via
+\fB\-y\fR
+or
+\fB\-k\fR\&.
+.RE
+.PP
+\fBgsstsig\fR
+.RS 4
+Use GSS\-TSIG to sign the updated\&. This is equivalent to specifying
+\fB\-g\fR
+on the command line\&.
+.RE
+.PP
+\fBoldgsstsig\fR
+.RS 4
+Use the Windows 2000 version of GSS\-TSIG to sign the updated\&. This is equivalent to specifying
+\fB\-o\fR
+on the command line\&.
+.RE
+.PP
+\fBrealm\fR {[realm_name]}
+.RS 4
+When using GSS\-TSIG use
+\fIrealm_name\fR
+rather than the default realm in
+krb5\&.conf\&. If no realm is specified the saved realm is cleared\&.
+.RE
+.PP
+\fBcheck\-names\fR {[yes_or_no]}
+.RS 4
+Turn on or off check\-names processing on records to be added\&. Check\-names has no effect on prerequisites or records to be deleted\&. By default check\-names processing is on\&. If check\-names processing fails the record will not be added to the UPDATE message\&.

+The prerequisite condition gets the name server to check that there are no resource records of any type for
+\fBnickname\&.example\&.com\fR\&. If there are, the update request fails\&. If this name does not exist, a CNAME for it is added\&. This ensures that when the CNAME is added, it cannot conflict with the long\-standing rule in RFC 1034 that a name must not exist as any other record type if it exists as a CNAME\&.

+
+    <para><command>nsupdate</command>
+      is used to submit Dynamic DNS Update requests as defined in RFC 2136
+      to a name server.
+      This allows resource records to be added or removed from a zone
+      without manually editing the zone file.
+      A single update request can contain requests to add or remove more than
+      one
+      resource record.
+    </para>
+    <para>
+      Zones that are under dynamic control via
+      <command>nsupdate</command>
+      or a DHCP server should not be edited by hand.
+      Manual edits could
+      conflict with dynamic updates and cause data to be lost.
+    </para>
+    <para>
+      The resource records that are dynamically added or removed with
+      <command>nsupdate</command>
+      have to be in the same zone.
+      Requests are sent to the zone's master server.
+      This is identified by the MNAME field of the zone's SOA record.
+    </para>
+    <para>
+      Transaction signatures can be used to authenticate the Dynamic
+      DNS updates.  These use the TSIG resource record type described
+      in RFC 2845 or the SIG(0) record described in RFC 2535 and
+      RFC 2931 or GSS-TSIG as described in RFC 3645.
+    </para>
+    <para>
+      TSIG relies on
+      a shared secret that should only be known to
+      <command>nsupdate</command> and the name server.
+      For instance, suitable <type>key</type> and
+      <type>server</type> statements would be added to
+      <filename>/etc/named.conf</filename> so that the name server
+      can associate the appropriate secret key and algorithm with
+      the IP address of the client application that will be using
+      TSIG authentication. You can use <command>ddns-confgen</command>
+      to generate suitable configuration fragments.
+      <command>nsupdate</command>
+      uses the <option>-y</option> or <option>-k</option> options
+      to provide the TSIG shared secret.  These options are mutually exclusive.
+    </para>
+    <para>
+      SIG(0) uses public key cryptography.
+      To use a SIG(0) key, the public key must be stored in a KEY
+      record in a zone served by the name server.
+    </para>
+    <para>
+      GSS-TSIG uses Kerberos credentials.  Standard GSS-TSIG mode
+      is switched on with the <option>-g</option> flag.  A
+      non-standards-compliant variant of GSS-TSIG used by Windows
+      2000 can be switched on with the <option>-o</option> flag.

+      The examples below show how
+      <command>nsupdate</command>
+      could be used to insert and delete resource records from the
+      <type>example.com</type>
+      zone.
+      Notice that the input in each example contains a trailing blank line so
+      that
+      a group of commands are sent as one dynamic update request to the
+      master name server for
+      <type>example.com</type>.
+
+      <programlisting>
+# nsupdate
+&gt; update delete oldhost.example.com A
+&gt; update add newhost.example.com 86400 A 172.16.1.1
+&gt; send
+</programlisting>
+    </para>
+    <para>
+      Any A records for
+      <type>oldhost.example.com</type>
+      are deleted.
+      And an A record for
+      <type>newhost.example.com</type>
+      with IP address 172.16.1.1 is added.
+      The newly-added record has a 1 day TTL (86400 seconds).
+      <programlisting>
+# nsupdate
+&gt; prereq nxdomain nickname.example.com
+&gt; update add nickname.example.com 86400 CNAME somehost.example.com
+&gt; send
+</programlisting>
+    </para>
+    <para>
+      The prerequisite condition gets the name server to check that there
+      are no resource records of any type for
+      <type>nickname.example.com</type>.
+
+      If there are, the update request fails.
+      If this name does not exist, a CNAME for it is added.
+      This ensures that when the CNAME is added, it cannot conflict with the
+      long-standing rule in RFC 1034 that a name must not exist as any other
+      record type if it exists as a CNAME.
+      (The rule has been updated for DNSSEC in RFC 2535 to allow CNAMEs to have
+      RRSIG, DNSKEY and NSEC records.)

+
+    <p><span class="command"><strong>nsupdate</strong></span>
+      is used to submit Dynamic DNS Update requests as defined in RFC 2136
+      to a name server.
+      This allows resource records to be added or removed from a zone
+      without manually editing the zone file.
+      A single update request can contain requests to add or remove more than
+      one
+      resource record.
+    </p>
+    <p>
+      Zones that are under dynamic control via
+      <span class="command"><strong>nsupdate</strong></span>
+      or a DHCP server should not be edited by hand.
+      Manual edits could
+      conflict with dynamic updates and cause data to be lost.
+    </p>
+    <p>
+      The resource records that are dynamically added or removed with
+      <span class="command"><strong>nsupdate</strong></span>
+      have to be in the same zone.
+      Requests are sent to the zone's master server.
+      This is identified by the MNAME field of the zone's SOA record.
+    </p>
+    <p>
+      Transaction signatures can be used to authenticate the Dynamic
+      DNS updates.  These use the TSIG resource record type described
+      in RFC 2845 or the SIG(0) record described in RFC 2535 and
+      RFC 2931 or GSS-TSIG as described in RFC 3645.
+    </p>
+    <p>
+      TSIG relies on
+      a shared secret that should only be known to
+      <span class="command"><strong>nsupdate</strong></span> and the name server.
+      For instance, suitable <span class="type">key</span> and
+      <span class="type">server</span> statements would be added to
+      <code class="filename">/etc/named.conf</code> so that the name server
+      can associate the appropriate secret key and algorithm with
+      the IP address of the client application that will be using
+      TSIG authentication. You can use <span class="command"><strong>ddns-confgen</strong></span>
+      to generate suitable configuration fragments.
+      <span class="command"><strong>nsupdate</strong></span>
+      uses the <code class="option">-y</code> or <code class="option">-k</code> options
+      to provide the TSIG shared secret.  These options are mutually exclusive.
+    </p>
+    <p>
+      SIG(0) uses public key cryptography.
+      To use a SIG(0) key, the public key must be stored in a KEY
+      record in a zone served by the name server.
+    </p>
+    <p>
+      GSS-TSIG uses Kerberos credentials.  Standard GSS-TSIG mode
+      is switched on with the <code class="option">-g</code> flag.  A
+      non-standards-compliant variant of GSS-TSIG used by Windows
+      2000 can be switched on with the <code class="option">-o</code> flag.
+    </p>

+      And an A record for
+      <span class="type">newhost.example.com</span>
+      with IP address 172.16.1.1 is added.

+      The prerequisite condition gets the name server to check that there
+      are no resource records of any type for
+      <span class="type">nickname.example.com</span>.
+
+      If there are, the update request fails.
+      If this name does not exist, a CNAME for it is added.
+      This ensures that when the CNAME is added, it cannot conflict with the
+      long-standing rule in RFC 1034 that a name must not exist as any other
+      record type if it exists as a CNAME.
+      (The rule has been updated for DNSSEC in RFC 2535 to allow CNAMEs to have
+      RRSIG, DNSKEY and NSEC records.)

+
+    <p>
+      The TSIG key is redundantly stored in two separate files.
+      This is a consequence of nsupdate using the DST library
+      for its cryptographic operations, and may change in future
+      releases.

+			BIND-9 PKCS#11 support
+
+Prerequisite
+
+The PKCS#11 support needs a PKCS#11 OpenSSL engine based on the Solaris one,
+released the 2008-12-02 for OpenSSL 0.9.8i, with back port of key by reference
+and some improvements, including user friendly PIN management. You may also
+use the original engine code.
+
+Compilation
+
+"configure --with-pkcs11 ..."
+
+PKCS#11 Libraries
+
+Tested with Solaris one with a SCA board and with openCryptoki with the
+software token. Known to work on Linux and Windows 2003 server so
+should work on most operating systems. For AEP Keyper or any device used
+only for its protected key store, please switch to the sign-only engine.
+
+OpenSSL Engines
+
+With PKCS#11 support the PKCS#11 engine is statically loaded but at its
+initialization it dynamically loads the PKCS#11 objects.
+Even the pre commands are therefore unused they are defined with:
+ SO_PATH:
+   define: PKCS11_SO_PATH
+   default: /usr/local/lib/engines/engine_pkcs11.so
+ MODULE_PATH:
+   define: PKCS11_MODULE_PATH
+   default: /usr/lib/libpkcs11.so
+Without PKCS#11 support, a specific OpenSSL engine can be still used
+by defining ENGINE_ID at compile time.
+
+PKCS#11 tools
+
+The contrib/pkcs11-keygen directory contains a set of experimental tools
+to handle keys stored in a Hardware Security Module at the benefit of BIND.
+
+The patch for OpenSSL 0.9.8i is in this directory. Read its README.pkcs11
+for the way to use it (these are the original notes so with the original
+path, etc. Define HAVE_GETPASSPHRASE if you have getpassphrase() on
+a operating system which is not Solaris.)
+
+Not all tools are supported on AEP Keyper but genkey and dnssec-keyfromlabel
+are functional.
+
+PIN management
+
+With the just fixed PKCS#11 OpenSSL engine, the PIN should be entered
+each time it is required. With the improved engine, the PIN should be
+entered the first time it is required or can be configured in the
+OpenSSL configuration file (aka. openssl.cnf) by adding in it:
+ - at the beginning:
+	openssl_conf = openssl_def
+ - at any place these sections:
+	[ openssl_def ]
+	engines = engine_section
+	[ engine_section ]
+	pkcs11 = pkcs11_section
+	[ pkcs11_section ]
+	PIN = put__your__pin__value__here
+
+Slot management
+
+The engine tries to use the first best slot but it is recommended
+to simply use the slot 0 (usual default, meta-slot on Solaris).
+
+Sign-only engine
+
+openssl.../crypto/engine/hw_pk11-kp.c and hw_pk11_pub-kp.c contain
+a stripped down version of hw_pk11.c and hw_pk11_pub.c files which
+has only the useful functions (i.e., signature with a RSA private
+key in the device protected key store and key loading).
+
+This engine should be used with a device which provides mainly
+a protected store and no acceleration. AEP Keyper is an example
+of such a device (BTW with the fully capable engine, key export
+must be enabled on this device and this configuration is not yet
+supported).
+
+Original engine
+
+If you are using the original engine and getpassphrase() is not defined, add:
+#define getpassphrase(x) getpass(x)
+in openssl.../crypto/engine/hw_pk11_pub.c
+
+Notes
+
+Some names here are registered trademarks, at least Solaris is a trademark
+of Sun Microsystems Inc...
+Include files are from RSA Labs., PKCS#11 version is 2.20 amendment 3.
+The PKCS#11 support is compatible with the forthcoming FIPS 140-2 support.

++ISC modified
++============
++
++The previous key naming scheme was kept for backward compatibility.
++
++The PKCS#11 engine exists in two flavors, crypto-accelerator and
++sign-only. The first one is from the Solaris patch and uses the
++PKCS#11 device for all crypto operations it supports. The second
++is a stripped down version which provides only the useful
++function (i.e., signature with a RSA private key in the device
++protected key store and key loading).
++
++As a hint PKCS#11 boards should use the crypto-accelerator flavor,
++external PKCS#11 devices the sign-only. SCA 6000 is an example
++of the first, AEP Keyper of the second.
++
++Note it is mandatory to set a pk11-flavor (and only one) in
++config/Configure.
++
++It is highly recommended to compile in (vs. as a DSO) the engine.
++The way to configure this is system dependent, on Unixes it is no-shared
++(and is in general the default), on WIN32 it is enable-static-engine
++(and still enable to build the OpenSSL libraries as DLLs).
++
++PKCS#11 engine support for OpenSSL 0.9.8l
++=========================================
++
++[Nov 19, 2009]
++
++Contents:
++
++Overview
++Revisions of the patch for 0.9.8 branch
++FAQs
++Feedback
++
++Overview
++========
++
++This patch containing code available in OpenSolaris adds support for PKCS#11
++engine into OpenSSL and implements PKCS#11 v2.20. It is to be applied against
++OpenSSL 0.9.8l source code distribution as shipped by OpenSSL.Org. Your system
++must provide PKCS#11 backend otherwise the patch is useless. You provide the
++PKCS#11 library name during the build configuration phase, see below.
++
++Patch can be applied like this:
++
++	# NOTE: use gtar if on Solaris
++	tar xfzv openssl-0.9.8l.tar.gz
++	# now download the patch to the current directory
++	# ...
++	cd openssl-0.9.8l
++	# NOTE: must use gpatch if on Solaris (is part of the system)
++	patch -p1 < path-to/pkcs11_engine-0.9.8l.patch.2009-11-19
++
++It is designed to support pure acceleration for RSA, DSA, DH and all the
++symetric ciphers and message digest algorithms that PKCS#11 and OpenSSL share
++except for missing support for patented algorithms MDC2, RC3, RC5 and IDEA.
++
++According to the PKCS#11 providers installed on your machine, it can support
++following mechanisms:
++
++	RSA, DSA, DH, RAND, DES-CBC, DES-EDE3-CBC, DES-ECB, DES-EDE3, RC4,
++	AES-128-CBC, AES-192-CBC, AES-256-CBC, AES-128-ECB, AES-192-ECB,
++	AES-256-ECB, AES-128-CTR, AES-192-CTR, AES-256-CTR, MD5, SHA1, SHA224,
++	SHA256, SHA384, SHA512
++
++Note that for AES counter mode the application must provide their own EVP
++functions since OpenSSL doesn't support counter mode through EVP yet. You may
++see OpenSSH source code (cipher.c) to get the idea how to do that. SunSSH is an
++example of code that uses the PKCS#11 engine and deals with the fork-safety
++problem (see engine.c and packet.c files if interested).
++
++You must provide the location of PKCS#11 library in your system to the
++configure script. You will be instructed to do that when you try to run the
++config script:
++
++	$ ./config 
++	Operating system: i86pc-whatever-solaris2
++	Configuring for solaris-x86-cc
++	You must set --pk11-libname for PKCS#11 library.
++	See README.pkcs11 for more information.
++
++Taking openCryptoki project on Linux AMD64 box as an example, you would run
++configure script like this:
++
++	./config --pk11-libname=/usr/lib64/pkcs11/PKCS11_API.so
++
++To check whether newly built openssl really supports PKCS#11 it's enough to run
++"apps/openssl engine" and look for "(pkcs11) PKCS #11 engine support" in the
++output. If you see no PKCS#11 engine support check that the built openssl binary
++and the PKCS#11 library from --pk11-libname don't conflict on 32/64 bits.
++
++The patch, during various phases of development, was tested on Solaris against
++PKCS#11 engine available from Solaris Cryptographic Framework (Solaris 10 and
++OpenSolaris) and also on Linux using PKCS#11 libraries from openCryptoki project
++(see openCryptoki website http://sourceforge.net/projects/opencryptoki for more
++information). Some Linux distributions even ship those libraries with the
++system. The patch should work on any system that is supported by OpenSSL itself
++and has functional PKCS#11 library.
++
++The patch contains "RSA Security Inc. PKCS #11 Cryptographic Token Interface
++(Cryptoki)" - files cryptoki.h, pkcs11.h, pkcs11f.h and pkcs11t.h which are
++copyrighted by RSA Security Inc., see pkcs11.h for more information.
++
++Other added/modified code in this patch is copyrighted by Sun Microsystems,
++Inc. and is released under the OpenSSL license (see LICENSE file for more
++information).

++
++FAQs
++====
++
++(1) my build failed on Linux distro with this error:
++
++../libcrypto.a(hw_pk11.o): In function `pk11_library_init':
++hw_pk11.c:(.text+0x20f5): undefined reference to `pthread_atfork'
++
++Answer:
++
++	- don't use "no-threads" when configuring
++	- if you didn't then OpenSSL failed to create a threaded library by
++	  default. You may manually edit Configure and try again. Look for the
++	  architecture that Configure printed, for example:
++
++Configured for linux-elf.
++
++	- then edit Configure, find string "linux-elf" (inluding the quotes),
++	  and add flags to support threads to the 4th column of the 2nd string.
++	  If you build with GCC then adding "-pthread" should be enough. With
++	  "linux-elf" as an example, you would add " -pthread" right after
++	  "-D_REENTRANT", like this:
++
++....-O3 -fomit-frame-pointer -Wall::-D_REENTRANT -pthread::-ldl:.....
++
++(2) I'm using MinGW/MSYS environment and get undeclared reference error for
++pthread_atfork() function when trying to build OpenSSL with the patch.
++
++Answer:
++
++	Sorry, pthread_atfork() is not implemented in the current pthread-win32
++	(as of Nov 2009). You can not use the patch there.
++
++

++ * It would be great if we could use pkcs11_kernel directly since this library
++ * offers hardware slots only. That's the easiest way to achieve the situation
++ * where we use the hardware accelerators when present and OpenSSL native code
++ * otherwise. That presumes the fact that OpenSSL native code is faster than the
++ * code in the soft token. It's a logical assumption - Crypto Framework has some
++ * inherent overhead so going there for the software implementation of a
++ * mechanism should be logically slower in contrast to the OpenSSL native code,
++ * presuming that both implementations are of similar speed. For example, the
++ * soft token for AES is roughly three times slower than OpenSSL for 64 byte
++ * blocks and still 20% slower for 8KB blocks. So, if we want to ship products
++ * that use the PKCS#11 engine by default, we must somehow avoid that regression
++ * on machines without hardware acceleration. That's why switching to the
++ * pkcs11_kernel library seems like a very good idea.
++ *
++ * The problem is that OpenSSL built with SunStudio is roughly 2x slower for
++ * asymmetric operations (RSA/DSA/DH) than the soft token built with the same
++ * compiler. That means that if we switched to pkcs11_kernel from the libpkcs11
++ * library, we would have had a performance regression on machines without
++ * hardware acceleration for asymmetric operations for all applications that use
++ * the PKCS#11 engine. There is one such application - Apache web server since
++ * it's shipped configured to use the PKCS#11 engine by default. Having said
++ * that, we can't switch to the pkcs11_kernel library now and have to come with
++ * a solution that, on non-accelerated machines, uses the OpenSSL native code
++ * for all symmetric ciphers and digests while it uses the soft token for
++ * asymmetric operations.
++ *
++ * This is the idea: dlopen() pkcs11_kernel directly and find out what
++ * mechanisms are there. We don't care about duplications (more slots can
++ * support the same mechanism), we just want to know what mechanisms can be
++ * possibly supported in hardware on that particular machine. As said before,
++ * pkcs11_kernel will show you hardware providers only.
++ *
++ * Then, we rely on the fact that since we use libpkcs11 library we will find
++ * the metaslot. When we go through the metaslot's mechanisms for symmetric
++ * ciphers and digests, we check that any found mechanism is in the table
++ * created using the pkcs11_kernel library. So, as a result we have two arrays
++ * of mechanisms that were advertised as supported in hardware which was the
++ * goal of that whole excercise. Thus, we can use libpkcs11 but avoid soft token
++ * code for symmetric ciphers and digests. See pk11_choose_slots() for more
++ * information.
++ *
++ * This is Solaris specific code, if SOLARIS_HW_SLOT_SELECTION is not defined

++/* Before including this file (pkcs11.h) (or pkcs11t.h by
++ * itself), 6 platform-specific macros must be defined.  These
++ * macros are described below, and typical definitions for them
++ * are also given.  Be advised that these definitions can depend
++ * on both the platform and the compiler used (and possibly also
++ * on whether a Cryptoki library is linked statically or
++ * dynamically).
++ *
++ * In addition to defining these 6 macros, the packing convention
++ * for Cryptoki structures should be set.  The Cryptoki
++ * convention on packing is that structures should be 1-byte
++ * aligned.
++ *
++ * If you're using Microsoft Developer Studio 5.0 to produce
++ * Win32 stuff, this might be done by using the following
++ * preprocessor directive before including pkcs11.h or pkcs11t.h:
++ *
++ * #pragma pack(push, cryptoki, 1)
++ *
++ * and using the following preprocessor directive after including
++ * pkcs11.h or pkcs11t.h:
++ *
++ * #pragma pack(pop, cryptoki)
++ *
++ * If you're using an earlier version of Microsoft Developer
++ * Studio to produce Win16 stuff, this might be done by using
++ * the following preprocessor directive before including
++ * pkcs11.h or pkcs11t.h:
++ *
++ * #pragma pack(1)
++ *
++ * In a UNIX environment, you're on your own for this.  You might
++ * not need to do (or be able to do!) anything.
++ *
++ *
++ * Now for the macros:
++ *
++ *
++ * 1. CK_PTR: The indirection string for making a pointer to an
++ * object.  It can be used like this:
++ *
++ * typedef CK_BYTE CK_PTR CK_BYTE_PTR;
++ *
++ * If you're using Microsoft Developer Studio 5.0 to produce
++ * Win32 stuff, it might be defined by:
++ *
++ * #define CK_PTR *
++ *
++ * If you're using an earlier version of Microsoft Developer
++ * Studio to produce Win16 stuff, it might be defined by:
++ *
++ * #define CK_PTR far *
++ *
++ * In a typical UNIX environment, it might be defined by:
++ *
++ * #define CK_PTR *
++ *
++ *
++ * 2. CK_DEFINE_FUNCTION(returnType, name): A macro which makes
++ * an exportable Cryptoki library function definition out of a
++ * return type and a function name.  It should be used in the
++ * following fashion to define the exposed Cryptoki functions in
++ * a Cryptoki library:
++ *
++ * CK_DEFINE_FUNCTION(CK_RV, C_Initialize)(
++ *   CK_VOID_PTR pReserved
++ * )
++ * {
++ *   ...
++ * }
++ *
++ * If you're using Microsoft Developer Studio 5.0 to define a
++ * function in a Win32 Cryptoki .dll, it might be defined by:
++ *
++ * #define CK_DEFINE_FUNCTION(returnType, name) \
++ *   returnType __declspec(dllexport) name
++ *
++ * If you're using an earlier version of Microsoft Developer
++ * Studio to define a function in a Win16 Cryptoki .dll, it
++ * might be defined by:
++ *
++ * #define CK_DEFINE_FUNCTION(returnType, name) \
++ *   returnType __export _far _pascal name
++ *
++ * In a UNIX environment, it might be defined by:
++ *
++ * #define CK_DEFINE_FUNCTION(returnType, name) \
++ *   returnType name
++ *
++ *
++ * 3. CK_DECLARE_FUNCTION(returnType, name): A macro which makes
++ * an importable Cryptoki library function declaration out of a
++ * return type and a function name.  It should be used in the
++ * following fashion:
++ *
++ * extern CK_DECLARE_FUNCTION(CK_RV, C_Initialize)(
++ *   CK_VOID_PTR pReserved
++ * );
++ *
++ * If you're using Microsoft Developer Studio 5.0 to declare a
++ * function in a Win32 Cryptoki .dll, it might be defined by:
++ *
++ * #define CK_DECLARE_FUNCTION(returnType, name) \
++ *   returnType __declspec(dllimport) name
++ *
++ * If you're using an earlier version of Microsoft Developer
++ * Studio to declare a function in a Win16 Cryptoki .dll, it
++ * might be defined by:
++ *
++ * #define CK_DECLARE_FUNCTION(returnType, name) \
++ *   returnType __export _far _pascal name
++ *
++ * In a UNIX environment, it might be defined by:
++ *
++ * #define CK_DECLARE_FUNCTION(returnType, name) \
++ *   returnType name
++ *
++ *
++ * 4. CK_DECLARE_FUNCTION_POINTER(returnType, name): A macro
++ * which makes a Cryptoki API function pointer declaration or
++ * function pointer type declaration out of a return type and a
++ * function name.  It should be used in the following fashion:
++ *
++ * // Define funcPtr to be a pointer to a Cryptoki API function
++ * // taking arguments args and returning CK_RV.
++ * CK_DECLARE_FUNCTION_POINTER(CK_RV, funcPtr)(args);
++ *
++ * or
++ *
++ * // Define funcPtrType to be the type of a pointer to a
++ * // Cryptoki API function taking arguments args and returning
++ * // CK_RV, and then define funcPtr to be a variable of type
++ * // funcPtrType.
++ * typedef CK_DECLARE_FUNCTION_POINTER(CK_RV, funcPtrType)(args);
++ * funcPtrType funcPtr;
++ *
++ * If you're using Microsoft Developer Studio 5.0 to access
++ * functions in a Win32 Cryptoki .dll, in might be defined by:
++ *
++ * #define CK_DECLARE_FUNCTION_POINTER(returnType, name) \
++ *   returnType __declspec(dllimport) (* name)
++ *
++ * If you're using an earlier version of Microsoft Developer
++ * Studio to access functions in a Win16 Cryptoki .dll, it might
++ * be defined by:
++ *
++ * #define CK_DECLARE_FUNCTION_POINTER(returnType, name) \
++ *   returnType __export _far _pascal (* name)
++ *
++ * In a UNIX environment, it might be defined by:
++ *
++ * #define CK_DECLARE_FUNCTION_POINTER(returnType, name) \
++ *   returnType (* name)
++ *
++ *
++ * 5. CK_CALLBACK_FUNCTION(returnType, name): A macro which makes
++ * a function pointer type for an application callback out of
++ * a return type for the callback and a name for the callback.
++ * It should be used in the following fashion:
++ *
++ * CK_CALLBACK_FUNCTION(CK_RV, myCallback)(args);
++ *
++ * to declare a function pointer, myCallback, to a callback
++ * which takes arguments args and returns a CK_RV.  It can also
++ * be used like this:
++ *
++ * typedef CK_CALLBACK_FUNCTION(CK_RV, myCallbackType)(args);
++ * myCallbackType myCallback;
++ *
++ * If you're using Microsoft Developer Studio 5.0 to do Win32
++ * Cryptoki development, it might be defined by:
++ *
++ * #define CK_CALLBACK_FUNCTION(returnType, name) \
++ *   returnType (* name)
++ *
++ * If you're using an earlier version of Microsoft Developer
++ * Studio to do Win16 development, it might be defined by:
++ *
++ * #define CK_CALLBACK_FUNCTION(returnType, name) \
++ *   returnType _far _pascal (* name)
++ *
++ * In a UNIX environment, it might be defined by:
++ *
++ * #define CK_CALLBACK_FUNCTION(returnType, name) \
++ *   returnType (* name)
++ *
++ *
++ * 6. NULL_PTR: This macro is the value of a NULL pointer.
++ *
++ * In any ANSI/ISO C environment (and in many others as well),
++ * this should best be defined by
++ *
++ * #ifndef NULL_PTR
++ * #define NULL_PTR 0

++ISC modified
++============
++
++The previous key naming scheme was kept for backward compatibility.
++
++The PKCS#11 engine exists in two flavors, crypto-accelerator and
++sign-only. The first one is from the Solaris patch and uses the
++PKCS#11 device for all crypto operations it supports. The second
++is a stripped down version which provides only the useful
++function (i.e., signature with a RSA private key in the device
++protected key store and key loading).
++
++As a hint PKCS#11 boards should use the crypto-accelerator flavor,
++external PKCS#11 devices the sign-only. SCA 6000 is an example
++of the first, AEP Keyper of the second.
++
++Note it is mandatory to set a pk11-flavor (and only one) in
++config/Configure.
++
++It is highly recommended to compile in (vs. as a DSO) the engine.
++The way to configure this is system dependent, on Unixes it is no-shared
++(and is in general the default), on WIN32 it is enable-static-engine
++(and still enable to build the OpenSSL libraries as DLLs).
++
++PKCS#11 engine support for OpenSSL 0.9.8l
++=========================================
++
++[Nov 19, 2009]
++
++Contents:
++
++Overview
++Revisions of the patch for 0.9.8 branch
++FAQs
++Feedback
++
++Overview
++========
++
++This patch containing code available in OpenSolaris adds support for PKCS#11
++engine into OpenSSL and implements PKCS#11 v2.20. It is to be applied against
++OpenSSL 0.9.8l source code distribution as shipped by OpenSSL.Org. Your system
++must provide PKCS#11 backend otherwise the patch is useless. You provide the
++PKCS#11 library name during the build configuration phase, see below.
++
++Patch can be applied like this:
++
++	# NOTE: use gtar if on Solaris
++	tar xfzv openssl-0.9.8l.tar.gz
++	# now download the patch to the current directory
++	# ...
++	cd openssl-0.9.8l
++	# NOTE: must use gpatch if on Solaris (is part of the system)
++	patch -p1 < path-to/pkcs11_engine-0.9.8l.patch.2009-11-19
++
++It is designed to support pure acceleration for RSA, DSA, DH and all the
++symetric ciphers and message digest algorithms that PKCS#11 and OpenSSL share
++except for missing support for patented algorithms MDC2, RC3, RC5 and IDEA.
++
++According to the PKCS#11 providers installed on your machine, it can support
++following mechanisms:
++
++	RSA, DSA, DH, RAND, DES-CBC, DES-EDE3-CBC, DES-ECB, DES-EDE3, RC4,
++	AES-128-CBC, AES-192-CBC, AES-256-CBC, AES-128-ECB, AES-192-ECB,
++	AES-256-ECB, AES-128-CTR, AES-192-CTR, AES-256-CTR, MD5, SHA1, SHA224,
++	SHA256, SHA384, SHA512
++
++Note that for AES counter mode the application must provide their own EVP
++functions since OpenSSL doesn't support counter mode through EVP yet. You may
++see OpenSSH source code (cipher.c) to get the idea how to do that. SunSSH is an
++example of code that uses the PKCS#11 engine and deals with the fork-safety
++problem (see engine.c and packet.c files if interested).
++
++You must provide the location of PKCS#11 library in your system to the
++configure script. You will be instructed to do that when you try to run the
++config script:
++
++	$ ./config 
++	Operating system: i86pc-whatever-solaris2
++	Configuring for solaris-x86-cc
++	You must set --pk11-libname for PKCS#11 library.
++	See README.pkcs11 for more information.
++
++Taking openCryptoki project on Linux AMD64 box as an example, you would run
++configure script like this:
++
++	./config --pk11-libname=/usr/lib64/pkcs11/PKCS11_API.so
++
++To check whether newly built openssl really supports PKCS#11 it's enough to run
++"apps/openssl engine" and look for "(pkcs11) PKCS #11 engine support" in the
++output. If you see no PKCS#11 engine support check that the built openssl binary
++and the PKCS#11 library from --pk11-libname don't conflict on 32/64 bits.
++
++The patch, during various phases of development, was tested on Solaris against
++PKCS#11 engine available from Solaris Cryptographic Framework (Solaris 10 and
++OpenSolaris) and also on Linux using PKCS#11 libraries from openCryptoki project
++(see openCryptoki website http://sourceforge.net/projects/opencryptoki for more
++information). Some Linux distributions even ship those libraries with the
++system. The patch should work on any system that is supported by OpenSSL itself
++and has functional PKCS#11 library.
++
++The patch contains "RSA Security Inc. PKCS #11 Cryptographic Token Interface
++(Cryptoki)" - files cryptoki.h, pkcs11.h, pkcs11f.h and pkcs11t.h which are
++copyrighted by RSA Security Inc., see pkcs11.h for more information.
++
++Other added/modified code in this patch is copyrighted by Sun Microsystems,
++Inc. and is released under the OpenSSL license (see LICENSE file for more
++information).

++2009-11-19
++- adjusted for OpenSSL version 0.9.8l
++
++- bugs and RFEs:
++
++	6479874 OpenSSL should support RSA key by reference/hardware keystores

++		atomically
++	6607307 pkcs#11 engine can't read RSA private keys
++	6652362 pk11_RSA_finish() is cutting corners
++	6662112 pk11_destroy_{rsa,dsa,dh}_key_objects() use locking in

++FAQs
++====
++
++(1) my build failed on Linux distro with this error:
++
++../libcrypto.a(hw_pk11.o): In function `pk11_library_init':
++hw_pk11.c:(.text+0x20f5): undefined reference to `pthread_atfork'
++
++Answer:
++
++	- don't use "no-threads" when configuring
++	- if you didn't then OpenSSL failed to create a threaded library by
++	  default. You may manually edit Configure and try again. Look for the
++	  architecture that Configure printed, for example:
++
++Configured for linux-elf.
++
++	- then edit Configure, find string "linux-elf" (inluding the quotes),
++	  and add flags to support threads to the 4th column of the 2nd string.
++	  If you build with GCC then adding "-pthread" should be enough. With
++	  "linux-elf" as an example, you would add " -pthread" right after
++	  "-D_REENTRANT", like this:
++
++....-O3 -fomit-frame-pointer -Wall::-D_REENTRANT -pthread::-ldl:.....
++
++(2) I'm using MinGW/MSYS environment and get undeclared reference error for
++pthread_atfork() function when trying to build OpenSSL with the patch.
++
++Answer:
++
++	Sorry, pthread_atfork() is not implemented in the current pthread-win32
++	(as of Nov 2009). You can not use the patch there.
++
++
++Feedback
++========
++
++Please send feedback to security-discuss@opensolaris.org. The patch was
++created by Jan.Pechanec@Sun.COM from code available in OpenSolaris.
++
++Latest version should be always available on http://blogs.sun.com/janp.

++ * It would be great if we could use pkcs11_kernel directly since this library
++ * offers hardware slots only. That's the easiest way to achieve the situation
++ * where we use the hardware accelerators when present and OpenSSL native code
++ * otherwise. That presumes the fact that OpenSSL native code is faster than the
++ * code in the soft token. It's a logical assumption - Crypto Framework has some
++ * inherent overhead so going there for the software implementation of a
++ * mechanism should be logically slower in contrast to the OpenSSL native code,
++ * presuming that both implementations are of similar speed. For example, the
++ * soft token for AES is roughly three times slower than OpenSSL for 64 byte
++ * blocks and still 20% slower for 8KB blocks. So, if we want to ship products
++ * that use the PKCS#11 engine by default, we must somehow avoid that regression
++ * on machines without hardware acceleration. That's why switching to the
++ * pkcs11_kernel library seems like a very good idea.
++ *
++ * The problem is that OpenSSL built with SunStudio is roughly 2x slower for
++ * asymmetric operations (RSA/DSA/DH) than the soft token built with the same
++ * compiler. That means that if we switched to pkcs11_kernel from the libpkcs11
++ * library, we would have had a performance regression on machines without
++ * hardware acceleration for asymmetric operations for all applications that use
++ * the PKCS#11 engine. There is one such application - Apache web server since
++ * it's shipped configured to use the PKCS#11 engine by default. Having said
++ * that, we can't switch to the pkcs11_kernel library now and have to come with
++ * a solution that, on non-accelerated machines, uses the OpenSSL native code
++ * for all symmetric ciphers and digests while it uses the soft token for
++ * asymmetric operations.
++ *
++ * This is the idea: dlopen() pkcs11_kernel directly and find out what
++ * mechanisms are there. We don't care about duplications (more slots can
++ * support the same mechanism), we just want to know what mechanisms can be
++ * possibly supported in hardware on that particular machine. As said before,
++ * pkcs11_kernel will show you hardware providers only.
++ *
++ * Then, we rely on the fact that since we use libpkcs11 library we will find
++ * the metaslot. When we go through the metaslot's mechanisms for symmetric
++ * ciphers and digests, we check that any found mechanism is in the table
++ * created using the pkcs11_kernel library. So, as a result we have two arrays
++ * of mechanisms that were advertised as supported in hardware which was the
++ * goal of that whole excercise. Thus, we can use libpkcs11 but avoid soft token
++ * code for symmetric ciphers and digests. See pk11_choose_slots() for more
++ * information.
++ *
++ * This is Solaris specific code, if SOLARIS_HW_SLOT_SELECTION is not defined

++/* Before including this file (pkcs11.h) (or pkcs11t.h by
++ * itself), 6 platform-specific macros must be defined.  These
++ * macros are described below, and typical definitions for them
++ * are also given.  Be advised that these definitions can depend
++ * on both the platform and the compiler used (and possibly also
++ * on whether a Cryptoki library is linked statically or
++ * dynamically).
++ *
++ * In addition to defining these 6 macros, the packing convention
++ * for Cryptoki structures should be set.  The Cryptoki
++ * convention on packing is that structures should be 1-byte
++ * aligned.
++ *
++ * If you're using Microsoft Developer Studio 5.0 to produce
++ * Win32 stuff, this might be done by using the following
++ * preprocessor directive before including pkcs11.h or pkcs11t.h:
++ *
++ * #pragma pack(push, cryptoki, 1)
++ *
++ * and using the following preprocessor directive after including
++ * pkcs11.h or pkcs11t.h:
++ *
++ * #pragma pack(pop, cryptoki)
++ *
++ * If you're using an earlier version of Microsoft Developer
++ * Studio to produce Win16 stuff, this might be done by using
++ * the following preprocessor directive before including
++ * pkcs11.h or pkcs11t.h:
++ *
++ * #pragma pack(1)
++ *
++ * In a UNIX environment, you're on your own for this.  You might
++ * not need to do (or be able to do!) anything.
++ *
++ *
++ * Now for the macros:
++ *
++ *
++ * 1. CK_PTR: The indirection string for making a pointer to an
++ * object.  It can be used like this:
++ *
++ * typedef CK_BYTE CK_PTR CK_BYTE_PTR;
++ *
++ * If you're using Microsoft Developer Studio 5.0 to produce
++ * Win32 stuff, it might be defined by:
++ *
++ * #define CK_PTR *
++ *
++ * If you're using an earlier version of Microsoft Developer
++ * Studio to produce Win16 stuff, it might be defined by:
++ *
++ * #define CK_PTR far *
++ *
++ * In a typical UNIX environment, it might be defined by:
++ *
++ * #define CK_PTR *
++ *
++ *
++ * 2. CK_DEFINE_FUNCTION(returnType, name): A macro which makes
++ * an exportable Cryptoki library function definition out of a
++ * return type and a function name.  It should be used in the
++ * following fashion to define the exposed Cryptoki functions in
++ * a Cryptoki library:
++ *
++ * CK_DEFINE_FUNCTION(CK_RV, C_Initialize)(
++ *   CK_VOID_PTR pReserved
++ * )
++ * {
++ *   ...
++ * }
++ *
++ * If you're using Microsoft Developer Studio 5.0 to define a
++ * function in a Win32 Cryptoki .dll, it might be defined by:
++ *
++ * #define CK_DEFINE_FUNCTION(returnType, name) \
++ *   returnType __declspec(dllexport) name
++ *
++ * If you're using an earlier version of Microsoft Developer
++ * Studio to define a function in a Win16 Cryptoki .dll, it
++ * might be defined by:
++ *
++ * #define CK_DEFINE_FUNCTION(returnType, name) \
++ *   returnType __export _far _pascal name
++ *
++ * In a UNIX environment, it might be defined by:
++ *
++ * #define CK_DEFINE_FUNCTION(returnType, name) \
++ *   returnType name
++ *
++ *
++ * 3. CK_DECLARE_FUNCTION(returnType, name): A macro which makes
++ * an importable Cryptoki library function declaration out of a
++ * return type and a function name.  It should be used in the
++ * following fashion:
++ *
++ * extern CK_DECLARE_FUNCTION(CK_RV, C_Initialize)(
++ *   CK_VOID_PTR pReserved
++ * );
++ *
++ * If you're using Microsoft Developer Studio 5.0 to declare a
++ * function in a Win32 Cryptoki .dll, it might be defined by:
++ *
++ * #define CK_DECLARE_FUNCTION(returnType, name) \
++ *   returnType __declspec(dllimport) name
++ *
++ * If you're using an earlier version of Microsoft Developer
++ * Studio to declare a function in a Win16 Cryptoki .dll, it
++ * might be defined by:
++ *
++ * #define CK_DECLARE_FUNCTION(returnType, name) \
++ *   returnType __export _far _pascal name
++ *
++ * In a UNIX environment, it might be defined by:
++ *
++ * #define CK_DECLARE_FUNCTION(returnType, name) \
++ *   returnType name
++ *
++ *
++ * 4. CK_DECLARE_FUNCTION_POINTER(returnType, name): A macro
++ * which makes a Cryptoki API function pointer declaration or
++ * function pointer type declaration out of a return type and a
++ * function name.  It should be used in the following fashion:
++ *
++ * // Define funcPtr to be a pointer to a Cryptoki API function
++ * // taking arguments args and returning CK_RV.
++ * CK_DECLARE_FUNCTION_POINTER(CK_RV, funcPtr)(args);
++ *
++ * or
++ *
++ * // Define funcPtrType to be the type of a pointer to a
++ * // Cryptoki API function taking arguments args and returning
++ * // CK_RV, and then define funcPtr to be a variable of type
++ * // funcPtrType.
++ * typedef CK_DECLARE_FUNCTION_POINTER(CK_RV, funcPtrType)(args);
++ * funcPtrType funcPtr;
++ *
++ * If you're using Microsoft Developer Studio 5.0 to access
++ * functions in a Win32 Cryptoki .dll, in might be defined by:
++ *
++ * #define CK_DECLARE_FUNCTION_POINTER(returnType, name) \
++ *   returnType __declspec(dllimport) (* name)
++ *
++ * If you're using an earlier version of Microsoft Developer
++ * Studio to access functions in a Win16 Cryptoki .dll, it might
++ * be defined by:
++ *
++ * #define CK_DECLARE_FUNCTION_POINTER(returnType, name) \
++ *   returnType __export _far _pascal (* name)
++ *
++ * In a UNIX environment, it might be defined by:
++ *
++ * #define CK_DECLARE_FUNCTION_POINTER(returnType, name) \
++ *   returnType (* name)
++ *
++ *
++ * 5. CK_CALLBACK_FUNCTION(returnType, name): A macro which makes
++ * a function pointer type for an application callback out of
++ * a return type for the callback and a name for the callback.
++ * It should be used in the following fashion:
++ *
++ * CK_CALLBACK_FUNCTION(CK_RV, myCallback)(args);
++ *
++ * to declare a function pointer, myCallback, to a callback
++ * which takes arguments args and returns a CK_RV.  It can also
++ * be used like this:
++ *
++ * typedef CK_CALLBACK_FUNCTION(CK_RV, myCallbackType)(args);
++ * myCallbackType myCallback;
++ *
++ * If you're using Microsoft Developer Studio 5.0 to do Win32
++ * Cryptoki development, it might be defined by:
++ *
++ * #define CK_CALLBACK_FUNCTION(returnType, name) \
++ *   returnType (* name)
++ *
++ * If you're using an earlier version of Microsoft Developer
++ * Studio to do Win16 development, it might be defined by:
++ *
++ * #define CK_CALLBACK_FUNCTION(returnType, name) \
++ *   returnType _far _pascal (* name)
++ *
++ * In a UNIX environment, it might be defined by:
++ *
++ * #define CK_CALLBACK_FUNCTION(returnType, name) \
++ *   returnType (* name)
++ *
++ *
++ * 6. NULL_PTR: This macro is the value of a NULL pointer.
++ *
++ * In any ANSI/ISO C environment (and in many others as well),
++ * this should best be defined by
++ *
++ * #ifndef NULL_PTR
++ * #define NULL_PTR 0

++ISC modified
++============
++
++The previous key naming scheme was kept for backward compatibility.
++
++The PKCS#11 engine exists in two flavors, crypto-accelerator and
++sign-only. The first one is from the Solaris patch and uses the
++PKCS#11 device for all crypto operations it supports. The second
++is a stripped down version which provides only the useful
++function (i.e., signature with a RSA private key in the device
++protected key store and key loading).
++
++As a hint PKCS#11 boards should use the crypto-accelerator flavor,
++external PKCS#11 devices the sign-only. SCA 6000 is an example
++of the first, AEP Keyper of the second.
++
++Note it is mandatory to set a pk11-flavor (and only one) in
++config/Configure.
++
++It is highly recommended to compile in (vs. as a DSO) the engine.
++The way to configure this is system dependent, on Unixes it is no-shared
++(and is in general the default), on WIN32 it is enable-static-engine
++(and still enable to build the OpenSSL libraries as DLLs).
++
++PKCS#11 engine support for OpenSSL 0.9.8l
++=========================================
++
++[Nov 19, 2009]
++

++Revisions of the patch for 0.9.8 branch

++Feedback
++
++Overview
++========
++
++This patch containing code available in OpenSolaris adds support for PKCS#11
++engine into OpenSSL and implements PKCS#11 v2.20. It is to be applied against
++OpenSSL 0.9.8l source code distribution as shipped by OpenSSL.Org. Your system
++must provide PKCS#11 backend otherwise the patch is useless. You provide the
++PKCS#11 library name during the build configuration phase, see below.
++
++Patch can be applied like this:
++
++	# NOTE: use gtar if on Solaris
++	tar xfzv openssl-0.9.8l.tar.gz
++	# now download the patch to the current directory
++	# ...
++	cd openssl-0.9.8l
++	# NOTE: must use gpatch if on Solaris (is part of the system)
++	patch -p1 < path-to/pkcs11_engine-0.9.8l.patch.2009-11-19
++
++It is designed to support pure acceleration for RSA, DSA, DH and all the
++symetric ciphers and message digest algorithms that PKCS#11 and OpenSSL share
++except for missing support for patented algorithms MDC2, RC3, RC5 and IDEA.
++
++According to the PKCS#11 providers installed on your machine, it can support
++following mechanisms:
++
++	RSA, DSA, DH, RAND, DES-CBC, DES-EDE3-CBC, DES-ECB, DES-EDE3, RC4,
++	AES-128-CBC, AES-192-CBC, AES-256-CBC, AES-128-ECB, AES-192-ECB,
++	AES-256-ECB, AES-128-CTR, AES-192-CTR, AES-256-CTR, MD5, SHA1, SHA224,
++	SHA256, SHA384, SHA512
++
++Note that for AES counter mode the application must provide their own EVP
++functions since OpenSSL doesn't support counter mode through EVP yet. You may
++see OpenSSH source code (cipher.c) to get the idea how to do that. SunSSH is an
++example of code that uses the PKCS#11 engine and deals with the fork-safety
++problem (see engine.c and packet.c files if interested).
++
++You must provide the location of PKCS#11 library in your system to the
++configure script. You will be instructed to do that when you try to run the
++config script:
++
++	$ ./config 
++	Operating system: i86pc-whatever-solaris2
++	Configuring for solaris-x86-cc
++	You must set --pk11-libname for PKCS#11 library.
++	See README.pkcs11 for more information.
++
++Taking openCryptoki project on Linux AMD64 box as an example, you would run
++configure script like this:
++
++	./config --pk11-libname=/usr/lib64/pkcs11/PKCS11_API.so
++
++To check whether newly built openssl really supports PKCS#11 it's enough to run
++"apps/openssl engine" and look for "(pkcs11) PKCS #11 engine support" in the
++output. If you see no PKCS#11 engine support check that the built openssl binary
++and the PKCS#11 library from --pk11-libname don't conflict on 32/64 bits.
++
++The patch, during various phases of development, was tested on Solaris against
++PKCS#11 engine available from Solaris Cryptographic Framework (Solaris 10 and
++OpenSolaris) and also on Linux using PKCS#11 libraries from openCryptoki project
++(see openCryptoki website http://sourceforge.net/projects/opencryptoki for more
++information). Some Linux distributions even ship those libraries with the
++system. The patch should work on any system that is supported by OpenSSL itself
++and has functional PKCS#11 library.
++
++The patch contains "RSA Security Inc. PKCS #11 Cryptographic Token Interface
++(Cryptoki)" - files cryptoki.h, pkcs11.h, pkcs11f.h and pkcs11t.h which are
++copyrighted by RSA Security Inc., see pkcs11.h for more information.
++
++Other added/modified code in this patch is copyrighted by Sun Microsystems,
++Inc. and is released under the OpenSSL license (see LICENSE file for more
++information).

++
++FAQs
++====
++
++(1) my build failed on Linux distro with this error:
++
++../libcrypto.a(hw_pk11.o): In function `pk11_library_init':
++hw_pk11.c:(.text+0x20f5): undefined reference to `pthread_atfork'
++
++Answer:
++
++	- don't use "no-threads" when configuring
++	- if you didn't then OpenSSL failed to create a threaded library by
++	  default. You may manually edit Configure and try again. Look for the
++	  architecture that Configure printed, for example:
++
++Configured for linux-elf.
++
++	- then edit Configure, find string "linux-elf" (inluding the quotes),
++	  and add flags to support threads to the 4th column of the 2nd string.
++	  If you build with GCC then adding "-pthread" should be enough. With
++	  "linux-elf" as an example, you would add " -pthread" right after
++	  "-D_REENTRANT", like this:
++
++....-O3 -fomit-frame-pointer -Wall::-D_REENTRANT -pthread::-ldl:.....
++
++(2) I'm using MinGW/MSYS environment and get undeclared reference error for
++pthread_atfork() function when trying to build OpenSSL with the patch.
++
++Answer:
++
++	Sorry, pthread_atfork() is not implemented in the current pthread-win32
++	(as of Nov 2009). You can not use the patch there.
++
++
++Feedback

++ * It would be great if we could use pkcs11_kernel directly since this library
++ * offers hardware slots only. That's the easiest way to achieve the situation
++ * where we use the hardware accelerators when present and OpenSSL native code
++ * otherwise. That presumes the fact that OpenSSL native code is faster than the
++ * code in the soft token. It's a logical assumption - Crypto Framework has some
++ * inherent overhead so going there for the software implementation of a
++ * mechanism should be logically slower in contrast to the OpenSSL native code,
++ * presuming that both implementations are of similar speed. For example, the
++ * soft token for AES is roughly three times slower than OpenSSL for 64 byte
++ * blocks and still 20% slower for 8KB blocks. So, if we want to ship products
++ * that use the PKCS#11 engine by default, we must somehow avoid that regression
++ * on machines without hardware acceleration. That's why switching to the
++ * pkcs11_kernel library seems like a very good idea.
++ *
++ * The problem is that OpenSSL built with SunStudio is roughly 2x slower for
++ * asymmetric operations (RSA/DSA/DH) than the soft token built with the same
++ * compiler. That means that if we switched to pkcs11_kernel from the libpkcs11
++ * library, we would have had a performance regression on machines without
++ * hardware acceleration for asymmetric operations for all applications that use
++ * the PKCS#11 engine. There is one such application - Apache web server since
++ * it's shipped configured to use the PKCS#11 engine by default. Having said
++ * that, we can't switch to the pkcs11_kernel library now and have to come with
++ * a solution that, on non-accelerated machines, uses the OpenSSL native code
++ * for all symmetric ciphers and digests while it uses the soft token for
++ * asymmetric operations.
++ *
++ * This is the idea: dlopen() pkcs11_kernel directly and find out what
++ * mechanisms are there. We don't care about duplications (more slots can
++ * support the same mechanism), we just want to know what mechanisms can be
++ * possibly supported in hardware on that particular machine. As said before,
++ * pkcs11_kernel will show you hardware providers only.
++ *
++ * Then, we rely on the fact that since we use libpkcs11 library we will find
++ * the metaslot. When we go through the metaslot's mechanisms for symmetric
++ * ciphers and digests, we check that any found mechanism is in the table
++ * created using the pkcs11_kernel library. So, as a result we have two arrays
++ * of mechanisms that were advertised as supported in hardware which was the
++ * goal of that whole excercise. Thus, we can use libpkcs11 but avoid soft token
++ * code for symmetric ciphers and digests. See pk11_choose_slots() for more
++ * information.
++ *
++ * This is Solaris specific code, if SOLARIS_HW_SLOT_SELECTION is not defined
++ * the code won't be used.

++/* Before including this file (pkcs11.h) (or pkcs11t.h by
++ * itself), 6 platform-specific macros must be defined.  These
++ * macros are described below, and typical definitions for them
++ * are also given.  Be advised that these definitions can depend
++ * on both the platform and the compiler used (and possibly also
++ * on whether a Cryptoki library is linked statically or
++ * dynamically).
++ *
++ * In addition to defining these 6 macros, the packing convention
++ * for Cryptoki structures should be set.  The Cryptoki
++ * convention on packing is that structures should be 1-byte
++ * aligned.
++ *
++ * If you're using Microsoft Developer Studio 5.0 to produce
++ * Win32 stuff, this might be done by using the following
++ * preprocessor directive before including pkcs11.h or pkcs11t.h:
++ *
++ * #pragma pack(push, cryptoki, 1)
++ *
++ * and using the following preprocessor directive after including
++ * pkcs11.h or pkcs11t.h:
++ *
++ * #pragma pack(pop, cryptoki)
++ *
++ * If you're using an earlier version of Microsoft Developer
++ * Studio to produce Win16 stuff, this might be done by using
++ * the following preprocessor directive before including
++ * pkcs11.h or pkcs11t.h:
++ *
++ * #pragma pack(1)
++ *
++ * In a UNIX environment, you're on your own for this.  You might
++ * not need to do (or be able to do!) anything.
++ *
++ *
++ * Now for the macros:
++ *
++ *
++ * 1. CK_PTR: The indirection string for making a pointer to an
++ * object.  It can be used like this:
++ *
++ * typedef CK_BYTE CK_PTR CK_BYTE_PTR;
++ *
++ * If you're using Microsoft Developer Studio 5.0 to produce
++ * Win32 stuff, it might be defined by:
++ *
++ * #define CK_PTR *
++ *
++ * If you're using an earlier version of Microsoft Developer
++ * Studio to produce Win16 stuff, it might be defined by:
++ *
++ * #define CK_PTR far *
++ *
++ * In a typical UNIX environment, it might be defined by:
++ *
++ * #define CK_PTR *
++ *
++ *
++ * 2. CK_DEFINE_FUNCTION(returnType, name): A macro which makes
++ * an exportable Cryptoki library function definition out of a
++ * return type and a function name.  It should be used in the
++ * following fashion to define the exposed Cryptoki functions in
++ * a Cryptoki library:
++ *
++ * CK_DEFINE_FUNCTION(CK_RV, C_Initialize)(
++ *   CK_VOID_PTR pReserved
++ * )
++ * {
++ *   ...
++ * }
++ *
++ * If you're using Microsoft Developer Studio 5.0 to define a
++ * function in a Win32 Cryptoki .dll, it might be defined by:
++ *
++ * #define CK_DEFINE_FUNCTION(returnType, name) \
++ *   returnType __declspec(dllexport) name
++ *
++ * If you're using an earlier version of Microsoft Developer
++ * Studio to define a function in a Win16 Cryptoki .dll, it
++ * might be defined by:
++ *
++ * #define CK_DEFINE_FUNCTION(returnType, name) \
++ *   returnType __export _far _pascal name
++ *
++ * In a UNIX environment, it might be defined by:
++ *
++ * #define CK_DEFINE_FUNCTION(returnType, name) \
++ *   returnType name
++ *
++ *
++ * 3. CK_DECLARE_FUNCTION(returnType, name): A macro which makes
++ * an importable Cryptoki library function declaration out of a
++ * return type and a function name.  It should be used in the
++ * following fashion:
++ *
++ * extern CK_DECLARE_FUNCTION(CK_RV, C_Initialize)(
++ *   CK_VOID_PTR pReserved
++ * );
++ *
++ * If you're using Microsoft Developer Studio 5.0 to declare a
++ * function in a Win32 Cryptoki .dll, it might be defined by:
++ *
++ * #define CK_DECLARE_FUNCTION(returnType, name) \

++ * If you're using an earlier version of Microsoft Developer
++ * Studio to declare a function in a Win16 Cryptoki .dll, it
++ * might be defined by:
++ *
++ * #define CK_DECLARE_FUNCTION(returnType, name) \
++ *   returnType __export _far _pascal name
++ *
++ * In a UNIX environment, it might be defined by:
++ *
++ * #define CK_DECLARE_FUNCTION(returnType, name) \
++ *   returnType name
++ *
++ *
++ * 4. CK_DECLARE_FUNCTION_POINTER(returnType, name): A macro
++ * which makes a Cryptoki API function pointer declaration or
++ * function pointer type declaration out of a return type and a
++ * function name.  It should be used in the following fashion:
++ *
++ * // Define funcPtr to be a pointer to a Cryptoki API function
++ * // taking arguments args and returning CK_RV.
++ * CK_DECLARE_FUNCTION_POINTER(CK_RV, funcPtr)(args);
++ *
++ * or

++ * // Cryptoki API function taking arguments args and returning
++ * // CK_RV, and then define funcPtr to be a variable of type
++ * // funcPtrType.
++ * typedef CK_DECLARE_FUNCTION_POINTER(CK_RV, funcPtrType)(args);
++ * funcPtrType funcPtr;
++ *
++ * If you're using Microsoft Developer Studio 5.0 to access
++ * functions in a Win32 Cryptoki .dll, in might be defined by:
++ *
++ * #define CK_DECLARE_FUNCTION_POINTER(returnType, name) \
++ *   returnType __declspec(dllimport) (* name)
++ *
++ * If you're using an earlier version of Microsoft Developer
++ * Studio to access functions in a Win16 Cryptoki .dll, it might
++ * be defined by:
++ *
++ * #define CK_DECLARE_FUNCTION_POINTER(returnType, name) \
++ *   returnType __export _far _pascal (* name)
++ *
++ * In a UNIX environment, it might be defined by:
++ *
++ * #define CK_DECLARE_FUNCTION_POINTER(returnType, name) \
++ *   returnType (* name)
++ *
++ *
++ * 5. CK_CALLBACK_FUNCTION(returnType, name): A macro which makes
++ * a function pointer type for an application callback out of
++ * a return type for the callback and a name for the callback.
++ * It should be used in the following fashion:
++ *
++ * CK_CALLBACK_FUNCTION(CK_RV, myCallback)(args);
++ *
++ * to declare a function pointer, myCallback, to a callback
++ * which takes arguments args and returns a CK_RV.  It can also
++ * be used like this:
++ *
++ * typedef CK_CALLBACK_FUNCTION(CK_RV, myCallbackType)(args);
++ * myCallbackType myCallback;
++ *
++ * If you're using Microsoft Developer Studio 5.0 to do Win32
++ * Cryptoki development, it might be defined by:
++ *
++ * #define CK_CALLBACK_FUNCTION(returnType, name) \
++ *   returnType (* name)
++ *
++ * If you're using an earlier version of Microsoft Developer
++ * Studio to do Win16 development, it might be defined by:
++ *
++ * #define CK_CALLBACK_FUNCTION(returnType, name) \
++ *   returnType _far _pascal (* name)
++ *
++ * In a UNIX environment, it might be defined by:
++ *
++ * #define CK_CALLBACK_FUNCTION(returnType, name) \
++ *   returnType (* name)
++ *
++ *
++ * 6. NULL_PTR: This macro is the value of a NULL pointer.
++ *
++ * In any ANSI/ISO C environment (and in many others as well),
++ * this should best be defined by
++ *
++ * #ifndef NULL_PTR

++ISC modified
++============
++
++The previous key naming scheme was kept for backward compatibility.
++
++The PKCS#11 engine exists in two flavors, crypto-accelerator and
++sign-only. The first one is from the Solaris patch and uses the
++PKCS#11 device for all crypto operations it supports. The second
++is a stripped down version which provides only the useful
++function (i.e., signature with a RSA private key in the device
++protected key store and key loading).
++
++As a hint PKCS#11 boards should use the crypto-accelerator flavor,
++external PKCS#11 devices the sign-only. SCA 6000 is an example
++of the first, AEP Keyper of the second.
++
++Note it is mandatory to set a pk11-flavor (and only one) in
++config/Configure.
++
++It is highly recommended to compile in (vs. as a DSO) the engine.
++The way to configure this is system dependent, on Unixes it is no-shared
++(and is in general the default), on WIN32 it is enable-static-engine
++(and still enable to build the OpenSSL libraries as DLLs).
++
++PKCS#11 engine support for OpenSSL 0.9.8l
++=========================================
++
++[Nov 19, 2009]
++
++Contents:
++
++Overview
++Revisions of the patch for 0.9.8 branch
++FAQs
++Feedback
++
++Overview
++========
++
++This patch containing code available in OpenSolaris adds support for PKCS#11
++engine into OpenSSL and implements PKCS#11 v2.20. It is to be applied against
++OpenSSL 0.9.8l source code distribution as shipped by OpenSSL.Org. Your system
++must provide PKCS#11 backend otherwise the patch is useless. You provide the
++PKCS#11 library name during the build configuration phase, see below.
++
++Patch can be applied like this:
++
++	# NOTE: use gtar if on Solaris
++	tar xfzv openssl-0.9.8l.tar.gz
++	# now download the patch to the current directory
++	# ...
++	cd openssl-0.9.8l
++	# NOTE: must use gpatch if on Solaris (is part of the system)
++	patch -p1 < path-to/pkcs11_engine-0.9.8l.patch.2009-11-19
++
++It is designed to support pure acceleration for RSA, DSA, DH and all the
++symetric ciphers and message digest algorithms that PKCS#11 and OpenSSL share
++except for missing support for patented algorithms MDC2, RC3, RC5 and IDEA.
++
++According to the PKCS#11 providers installed on your machine, it can support
++following mechanisms:
++
++	RSA, DSA, DH, RAND, DES-CBC, DES-EDE3-CBC, DES-ECB, DES-EDE3, RC4,
++	AES-128-CBC, AES-192-CBC, AES-256-CBC, AES-128-ECB, AES-192-ECB,
++	AES-256-ECB, AES-128-CTR, AES-192-CTR, AES-256-CTR, MD5, SHA1, SHA224,
++	SHA256, SHA384, SHA512
++
++Note that for AES counter mode the application must provide their own EVP
++functions since OpenSSL doesn't support counter mode through EVP yet. You may
++see OpenSSH source code (cipher.c) to get the idea how to do that. SunSSH is an
++example of code that uses the PKCS#11 engine and deals with the fork-safety
++problem (see engine.c and packet.c files if interested).
++
++You must provide the location of PKCS#11 library in your system to the
++configure script. You will be instructed to do that when you try to run the
++config script:
++
++	$ ./config 
++	Operating system: i86pc-whatever-solaris2
++	Configuring for solaris-x86-cc
++	You must set --pk11-libname for PKCS#11 library.
++	See README.pkcs11 for more information.
++
++Taking openCryptoki project on Linux AMD64 box as an example, you would run
++configure script like this:
++
++	./config --pk11-libname=/usr/lib64/pkcs11/PKCS11_API.so
++
++To check whether newly built openssl really supports PKCS#11 it's enough to run
++"apps/openssl engine" and look for "(pkcs11) PKCS #11 engine support" in the
++output. If you see no PKCS#11 engine support check that the built openssl binary
++and the PKCS#11 library from --pk11-libname don't conflict on 32/64 bits.
++
++The patch, during various phases of development, was tested on Solaris against
++PKCS#11 engine available from Solaris Cryptographic Framework (Solaris 10 and
++OpenSolaris) and also on Linux using PKCS#11 libraries from openCryptoki project
++(see openCryptoki website http://sourceforge.net/projects/opencryptoki for more
++information). Some Linux distributions even ship those libraries with the
++system. The patch should work on any system that is supported by OpenSSL itself
++and has functional PKCS#11 library.
++
++The patch contains "RSA Security Inc. PKCS #11 Cryptographic Token Interface
++(Cryptoki)" - files cryptoki.h, pkcs11.h, pkcs11f.h and pkcs11t.h which are
++copyrighted by RSA Security Inc., see pkcs11.h for more information.
++
++Other added/modified code in this patch is copyrighted by Sun Microsystems,
++Inc. and is released under the OpenSSL license (see LICENSE file for more
++information).

++
++FAQs
++====
++
++(1) my build failed on Linux distro with this error:
++
++../libcrypto.a(hw_pk11.o): In function `pk11_library_init':
++hw_pk11.c:(.text+0x20f5): undefined reference to `pthread_atfork'
++
++Answer:
++
++	- don't use "no-threads" when configuring
++	- if you didn't then OpenSSL failed to create a threaded library by
++	  default. You may manually edit Configure and try again. Look for the
++	  architecture that Configure printed, for example:
++
++Configured for linux-elf.
++
++	- then edit Configure, find string "linux-elf" (inluding the quotes),
++	  and add flags to support threads to the 4th column of the 2nd string.
++	  If you build with GCC then adding "-pthread" should be enough. With
++	  "linux-elf" as an example, you would add " -pthread" right after
++	  "-D_REENTRANT", like this:
++
++....-O3 -fomit-frame-pointer -Wall::-D_REENTRANT -pthread::-ldl:.....
++
++(2) I'm using MinGW/MSYS environment and get undeclared reference error for
++pthread_atfork() function when trying to build OpenSSL with the patch.
++
++Answer:
++
++	Sorry, pthread_atfork() is not implemented in the current pthread-win32
++	(as of Nov 2009). You can not use the patch there.
++

++ * It would be great if we could use pkcs11_kernel directly since this library
++ * offers hardware slots only. That's the easiest way to achieve the situation
++ * where we use the hardware accelerators when present and OpenSSL native code
++ * otherwise. That presumes the fact that OpenSSL native code is faster than the
++ * code in the soft token. It's a logical assumption - Crypto Framework has some
++ * inherent overhead so going there for the software implementation of a
++ * mechanism should be logically slower in contrast to the OpenSSL native code,
++ * presuming that both implementations are of similar speed. For example, the
++ * soft token for AES is roughly three times slower than OpenSSL for 64 byte
++ * blocks and still 20% slower for 8KB blocks. So, if we want to ship products
++ * that use the PKCS#11 engine by default, we must somehow avoid that regression
++ * on machines without hardware acceleration. That's why switching to the
++ * pkcs11_kernel library seems like a very good idea.
++ *
++ * The problem is that OpenSSL built with SunStudio is roughly 2x slower for
++ * asymmetric operations (RSA/DSA/DH) than the soft token built with the same
++ * compiler. That means that if we switched to pkcs11_kernel from the libpkcs11
++ * library, we would have had a performance regression on machines without
++ * hardware acceleration for asymmetric operations for all applications that use
++ * the PKCS#11 engine. There is one such application - Apache web server since
++ * it's shipped configured to use the PKCS#11 engine by default. Having said
++ * that, we can't switch to the pkcs11_kernel library now and have to come with
++ * a solution that, on non-accelerated machines, uses the OpenSSL native code
++ * for all symmetric ciphers and digests while it uses the soft token for
++ * asymmetric operations.
++ *
++ * This is the idea: dlopen() pkcs11_kernel directly and find out what
++ * mechanisms are there. We don't care about duplications (more slots can
++ * support the same mechanism), we just want to know what mechanisms can be
++ * possibly supported in hardware on that particular machine. As said before,
++ * pkcs11_kernel will show you hardware providers only.
++ *
++ * Then, we rely on the fact that since we use libpkcs11 library we will find
++ * the metaslot. When we go through the metaslot's mechanisms for symmetric
++ * ciphers and digests, we check that any found mechanism is in the table
++ * created using the pkcs11_kernel library. So, as a result we have two arrays
++ * of mechanisms that were advertised as supported in hardware which was the
++ * goal of that whole excercise. Thus, we can use libpkcs11 but avoid soft token
++ * code for symmetric ciphers and digests. See pk11_choose_slots() for more
++ * information.
++ *
++ * This is Solaris specific code, if SOLARIS_HW_SLOT_SELECTION is not defined
++ * the code won't be used.

++ * on whether a Cryptoki library is linked statically or
++ * dynamically).
++ *
++ * In addition to defining these 6 macros, the packing convention
++ * for Cryptoki structures should be set.  The Cryptoki
++ * convention on packing is that structures should be 1-byte
++ * aligned.
++ *
++ * If you're using Microsoft Developer Studio 5.0 to produce
++ * Win32 stuff, this might be done by using the following
++ * preprocessor directive before including pkcs11.h or pkcs11t.h:
++ *
++ * #pragma pack(push, cryptoki, 1)
++ *
++ * and using the following preprocessor directive after including
++ * pkcs11.h or pkcs11t.h:
++ *
++ * #pragma pack(pop, cryptoki)
++ *
++ * If you're using an earlier version of Microsoft Developer
++ * Studio to produce Win16 stuff, this might be done by using
++ * the following preprocessor directive before including
++ * pkcs11.h or pkcs11t.h:
++ *
++ * #pragma pack(1)
++ *
++ * In a UNIX environment, you're on your own for this.  You might
++ * not need to do (or be able to do!) anything.
++ *
++ *
++ * Now for the macros:
++ *
++ *
++ * 1. CK_PTR: The indirection string for making a pointer to an
++ * object.  It can be used like this:
++ *
++ * typedef CK_BYTE CK_PTR CK_BYTE_PTR;
++ *
++ * If you're using Microsoft Developer Studio 5.0 to produce
++ * Win32 stuff, it might be defined by:
++ *
++ * #define CK_PTR *
++ *
++ * If you're using an earlier version of Microsoft Developer
++ * Studio to produce Win16 stuff, it might be defined by:
++ *
++ * #define CK_PTR far *
++ *
++ * In a typical UNIX environment, it might be defined by:
++ *
++ * #define CK_PTR *
++ *
++ *
++ * 2. CK_DEFINE_FUNCTION(returnType, name): A macro which makes
++ * an exportable Cryptoki library function definition out of a
++ * return type and a function name.  It should be used in the
++ * following fashion to define the exposed Cryptoki functions in
++ * a Cryptoki library:
++ *
++ * CK_DEFINE_FUNCTION(CK_RV, C_Initialize)(
++ *   CK_VOID_PTR pReserved
++ * )
++ * {
++ *   ...
++ * }
++ *
++ * If you're using Microsoft Developer Studio 5.0 to define a
++ * function in a Win32 Cryptoki .dll, it might be defined by:
++ *
++ * #define CK_DEFINE_FUNCTION(returnType, name) \
++ *   returnType __declspec(dllexport) name
++ *
++ * If you're using an earlier version of Microsoft Developer
++ * Studio to define a function in a Win16 Cryptoki .dll, it
++ * might be defined by:
++ *
++ * #define CK_DEFINE_FUNCTION(returnType, name) \
++ *   returnType __export _far _pascal name
++ *
++ * In a UNIX environment, it might be defined by:
++ *
++ * #define CK_DEFINE_FUNCTION(returnType, name) \
++ *   returnType name
++ *
++ *
++ * 3. CK_DECLARE_FUNCTION(returnType, name): A macro which makes
++ * an importable Cryptoki library function declaration out of a
++ * return type and a function name.  It should be used in the
++ * following fashion:
++ *
++ * extern CK_DECLARE_FUNCTION(CK_RV, C_Initialize)(
++ *   CK_VOID_PTR pReserved
++ * );
++ *
++ * If you're using Microsoft Developer Studio 5.0 to declare a
++ * function in a Win32 Cryptoki .dll, it might be defined by:
++ *
++ * #define CK_DECLARE_FUNCTION(returnType, name) \
++ *   returnType __declspec(dllimport) name
++ *
++ * If you're using an earlier version of Microsoft Developer
++ * Studio to declare a function in a Win16 Cryptoki .dll, it
++ * might be defined by:
++ *
++ * #define CK_DECLARE_FUNCTION(returnType, name) \
++ *   returnType __export _far _pascal name
++ *
++ * In a UNIX environment, it might be defined by:
++ *
++ * #define CK_DECLARE_FUNCTION(returnType, name) \
++ *   returnType name
++ *
++ *
++ * 4. CK_DECLARE_FUNCTION_POINTER(returnType, name): A macro
++ * which makes a Cryptoki API function pointer declaration or
++ * function pointer type declaration out of a return type and a
++ * function name.  It should be used in the following fashion:
++ *
++ * // Define funcPtr to be a pointer to a Cryptoki API function
++ * // taking arguments args and returning CK_RV.
++ * CK_DECLARE_FUNCTION_POINTER(CK_RV, funcPtr)(args);
++ *
++ * or
++ *
++ * // Define funcPtrType to be the type of a pointer to a
++ * // Cryptoki API function taking arguments args and returning
++ * // CK_RV, and then define funcPtr to be a variable of type
++ * // funcPtrType.
++ * typedef CK_DECLARE_FUNCTION_POINTER(CK_RV, funcPtrType)(args);
++ * funcPtrType funcPtr;
++ *
++ * If you're using Microsoft Developer Studio 5.0 to access
++ * functions in a Win32 Cryptoki .dll, in might be defined by:
++ *
++ * #define CK_DECLARE_FUNCTION_POINTER(returnType, name) \
++ *   returnType __declspec(dllimport) (* name)
++ *
++ * If you're using an earlier version of Microsoft Developer
++ * Studio to access functions in a Win16 Cryptoki .dll, it might
++ * be defined by:
++ *
++ * #define CK_DECLARE_FUNCTION_POINTER(returnType, name) \
++ *   returnType __export _far _pascal (* name)
++ *
++ * In a UNIX environment, it might be defined by:
++ *
++ * #define CK_DECLARE_FUNCTION_POINTER(returnType, name) \
++ *   returnType (* name)
++ *
++ *
++ * 5. CK_CALLBACK_FUNCTION(returnType, name): A macro which makes
++ * a function pointer type for an application callback out of
++ * a return type for the callback and a name for the callback.
++ * It should be used in the following fashion:
++ *
++ * CK_CALLBACK_FUNCTION(CK_RV, myCallback)(args);
++ *
++ * to declare a function pointer, myCallback, to a callback
++ * which takes arguments args and returns a CK_RV.  It can also
++ * be used like this:
++ *
++ * typedef CK_CALLBACK_FUNCTION(CK_RV, myCallbackType)(args);
++ * myCallbackType myCallback;
++ *
++ * If you're using Microsoft Developer Studio 5.0 to do Win32
++ * Cryptoki development, it might be defined by:
++ *
++ * #define CK_CALLBACK_FUNCTION(returnType, name) \
++ *   returnType (* name)
++ *
++ * If you're using an earlier version of Microsoft Developer
++ * Studio to do Win16 development, it might be defined by:
++ *
++ * #define CK_CALLBACK_FUNCTION(returnType, name) \
++ *   returnType _far _pascal (* name)
++ *
++ * In a UNIX environment, it might be defined by:
++ *
++ * #define CK_CALLBACK_FUNCTION(returnType, name) \
++ *   returnType (* name)
++ *
++ *
++ * 6. NULL_PTR: This macro is the value of a NULL pointer.
++ *
++ * In any ANSI/ISO C environment (and in many others as well),
++ * this should best be defined by
++ *
++ * #ifndef NULL_PTR
++ * #define NULL_PTR 0
++ * #endif

+.SH "DESCRIPTION"
+.PP
+\fBpkcs11\-destroy\fR
+destroys keys stored in a PKCS#11 device, identified by their
+\fBID\fR
+or
+\fBlabel\fR\&.
+.PP
+Matching keys are displayed before being destroyed\&. By default, there is a five second delay to allow the user to interrupt the process before the destruction takes place\&.
+.SH "ARGUMENTS"
+.PP
+\-m \fImodule\fR
+.RS 4
+Specify the PKCS#11 provider module\&. This must be the full path to a shared library object implementing the PKCS#11 API for the device\&.
+.RE
+.PP
+\-s \fIslot\fR
+.RS 4
+Open the session with the given PKCS#11 slot\&. The default is slot 0\&.
+.RE
+.PP
+\-i \fIID\fR
+.RS 4
+Destroy keys with the given object ID\&.
+.RE
+.PP
+\-l \fIlabel\fR
+.RS 4
+Destroy keys with the given label\&.
+.RE
+.PP
+\-p \fIPIN\fR
+.RS 4
+Specify the PIN for the device\&. If no PIN is provided on the command line,
+\fBpkcs11\-destroy\fR
+will prompt for it\&.
+.RE
+.PP
+\-w \fIseconds\fR
+.RS 4
+Specify how long to pause before carrying out key destruction\&. The default is five seconds\&. If set to

+.SH "DESCRIPTION"
+.PP
+\fBpkcs11\-keygen\fR
+causes a PKCS#11 device to generate a new key pair with the given
+\fBlabel\fR
+(which must be unique) and with
+\fBkeysize\fR
+bits of prime\&.
+.SH "ARGUMENTS"
+.PP
+\-a \fIalgorithm\fR
+.RS 4
+Specify the key algorithm class: Supported classes are RSA, DSA, DH, ECC and ECX\&. In addition to these strings, the
+\fBalgorithm\fR
+can be specified as a DNSSEC signing algorithm that will be used with this key; for example, NSEC3RSASHA1 maps to RSA, ECDSAP256SHA256 maps to ECC, and ED25519 to ECX\&. The default class is "RSA"\&.
+.RE
+.PP
+\-b \fIkeysize\fR
+.RS 4
+Create the key pair with
+\fBkeysize\fR
+bits of prime\&. For ECC keys, the only valid values are 256 and 384, and the default is 256\&. For ECX kyes, the only valid values are 256 and 456, and the default is 256\&.
+.RE
+.PP
+\-e
+.RS 4
+For RSA keys only, use a large exponent\&.
+.RE
+.PP
+\-i \fIid\fR
+.RS 4
+Create key objects with id\&. The id is either an unsigned short 2 byte or an unsigned long 4 byte number\&.
+.RE
+.PP
+\-m \fImodule\fR
+.RS 4
+Specify the PKCS#11 provider module\&. This must be the full path to a shared library object implementing the PKCS#11 API for the device\&.
+.RE
+.PP
+\-P
+.RS 4
+Set the new private key to be non\-sensitive and extractable\&. The allows the private key data to be read from the PKCS#11 device\&. The default is for private keys to be sensitive and non\-extractable\&.
+.RE
+.PP
+\-p \fIPIN\fR
+.RS 4
+Specify the PIN for the device\&. If no PIN is provided on the command line,
+\fBpkcs11\-keygen\fR
+will prompt for it\&.
+.RE
+.PP
+\-q
+.RS 4
+Quiet mode: suppress unnecessary output\&.
+.RE
+.PP
+\-S
+.RS 4
+For Diffie\-Hellman (DH) keys only, use a special prime of 768, 1024 or 1536 bit size and base (aka generator) 2\&. If not specified, bit size will default to 1024\&.
+.RE
+.PP
+\-s \fIslot\fR
+.RS 4
+Open the session with the given PKCS#11 slot\&. The default is slot 0\&.

+\fBdnssec\-coverage\fR [\fB\-K\ \fR\fB\fIdirectory\fR\fR] [\fB\-l\ \fR\fB\fIlength\fR\fR] [\fB\-f\ \fR\fB\fIfile\fR\fR] [\fB\-d\ \fR\fB\fIDNSKEY\ TTL\fR\fR] [\fB\-m\ \fR\fB\fImax\ TTL\fR\fR] [\fB\-r\ \fR\fB\fIinterval\fR\fR] [\fB\-c\ \fR\fB\fIcompilezone\ path\fR\fR] [\fB\-k\fR] [\fB\-z\fR] [zone...]
+.SH "DESCRIPTION"
+.PP
+\fBdnssec\-coverage\fR
+verifies that the DNSSEC keys for a given zone or a set of zones have timing metadata set properly to ensure no future lapses in DNSSEC coverage\&.
+.PP
+If
+\fBzone\fR
+is specified, then keys found in the key repository matching that zone are scanned, and an ordered list is generated of the events scheduled for that key (i\&.e\&., publication, activation, inactivation, deletion)\&. The list of events is walked in order of occurrence\&. Warnings are generated if any event is scheduled which could cause the zone to enter a state in which validation failures might occur: for example, if the number of published or active keys for a given algorithm drops to zero, or if a key is deleted from the zone too soon after a new key is rolled, and cached data signed by the prior key has not had time to expire from resolver caches\&.
+.PP
+If
+\fBzone\fR
+is not specified, then all keys in the key repository will be scanned, and all zones for which there are keys will be analyzed\&. (Note: This method of reporting is only accurate if all the zones that have keys in a given repository share the same TTL parameters\&.)
+.SH "OPTIONS"
+.PP
+\-K \fIdirectory\fR
+.RS 4
+Sets the directory in which keys can be found\&. Defaults to the current working directory\&.
+.RE
+.PP
+\-f \fIfile\fR
+.RS 4
+If a
+\fBfile\fR
+is specified, then the zone is read from that file; the largest TTL and the DNSKEY TTL are determined directly from the zone data, and the
+\fB\-m\fR
+and
+\fB\-d\fR
+options do not need to be specified on the command line\&.
+.RE
+.PP
+\-l \fIduration\fR
+.RS 4
+The length of time to check for DNSSEC coverage\&. Key events scheduled further into the future than
+\fBduration\fR
+will be ignored, and assumed to be correct\&.
+.sp
+The value of
+\fBduration\fR
+can be set in seconds, or in larger units of time by adding a suffix: \*(Aqmi\*(Aq for minutes, \*(Aqh\*(Aq for hours, \*(Aqd\*(Aq for days, \*(Aqw\*(Aq for weeks, \*(Aqmo\*(Aq for months, \*(Aqy\*(Aq for years\&.
+.RE
+.PP
+\-m \fImaximum TTL\fR
+.RS 4
+Sets the value to be used as the maximum TTL for the zone or zones being analyzed when determining whether there is a possibility of validation failure\&. When a zone\-signing key is deactivated, there must be enough time for the record in the zone with the longest TTL to have expired from resolver caches before that key can be purged from the DNSKEY RRset\&. If that condition does not apply, a warning will be generated\&.
+.sp
+The length of the TTL can be set in seconds, or in larger units of time by adding a suffix: \*(Aqmi\*(Aq for minutes, \*(Aqh\*(Aq for hours, \*(Aqd\*(Aq for days, \*(Aqw\*(Aq for weeks, \*(Aqmo\*(Aq for months, \*(Aqy\*(Aq for years\&.
+.sp
+This option is not necessary if the
+\fB\-f\fR
+has been used to specify a zone file\&. If
+\fB\-f\fR
+has been specified, this option may still be used; it will override the value found in the file\&.
+.sp
+If this option is not used and the maximum TTL cannot be retrieved from a zone file, a warning is generated and a default value of 1 week is used\&.
+.RE
+.PP
+\-d \fIDNSKEY TTL\fR
+.RS 4
+Sets the value to be used as the DNSKEY TTL for the zone or zones being analyzed when determining whether there is a possibility of validation failure\&. When a key is rolled (that is, replaced with a new key), there must be enough time for the old DNSKEY RRset to have expired from resolver caches before the new key is activated and begins generating signatures\&. If that condition does not apply, a warning will be generated\&.
+.sp
+The length of the TTL can be set in seconds, or in larger units of time by adding a suffix: \*(Aqmi\*(Aq for minutes, \*(Aqh\*(Aq for hours, \*(Aqd\*(Aq for days, \*(Aqw\*(Aq for weeks, \*(Aqmo\*(Aq for months, \*(Aqy\*(Aq for years\&.
+.sp
+This option is not necessary if
+\fB\-f\fR
+has been used to specify a zone file from which the TTL of the DNSKEY RRset can be read, or if a default key TTL was set using ith the
+\fB\-L\fR
+to
+\fBdnssec\-keygen\fR\&. If either of those is true, this option may still be used; it will override the values found in the zone file or the key file\&.
+.sp
+If this option is not used and the key TTL cannot be retrieved from the zone file or the key file, then a warning is generated and a default value of 1 day is used\&.
+.RE
+.PP
+\-r \fIresign interval\fR
+.RS 4
+Sets the value to be used as the resign interval for the zone or zones being analyzed when determining whether there is a possibility of validation failure\&. This value defaults to 22\&.5 days, which is also the default in
+\fBnamed\fR\&. However, if it has been changed by the
+\fBsig\-validity\-interval\fR
+option in
+named\&.conf, then it should also be changed here\&.
+.sp
+The length of the interval can be set in seconds, or in larger units of time by adding a suffix: \*(Aqmi\*(Aq for minutes, \*(Aqh\*(Aq for hours, \*(Aqd\*(Aq for days, \*(Aqw\*(Aq for weeks, \*(Aqmo\*(Aq for months, \*(Aqy\*(Aq for years\&.
+.RE

+Only check KSK coverage; ignore ZSK events\&. Cannot be used with
+\fB\-z\fR\&.
+.RE
+.PP

+      verifies that the DNSSEC keys for a given zone or a set of zones
+      have timing metadata set properly to ensure no future lapses in DNSSEC
+      coverage.
+    </p>
+    <p>
+      If <code class="option">zone</code> is specified, then keys found in
+      the key repository matching that zone are scanned, and an ordered
+      list is generated of the events scheduled for that key (i.e.,
+      publication, activation, inactivation, deletion).  The list of
+      events is walked in order of occurrence.  Warnings are generated
+      if any event is scheduled which could cause the zone to enter a
+      state in which validation failures might occur: for example, if
+      the number of published or active keys for a given algorithm drops
+      to zero, or if a key is deleted from the zone too soon after a new
+      key is rolled, and cached data signed by the prior key has not had
+      time to expire from resolver caches.
+    </p>
+    <p>
+      If <code class="option">zone</code> is not specified, then all keys in the
+      key repository will be scanned, and all zones for which there are
+      keys will be analyzed.  (Note: This method of reporting is only
+      accurate if all the zones that have keys in a given repository
+      share the same TTL parameters.)

+.SH "DESCRIPTION"
+.PP
+\fBdnssec\-keymgr\fR
+is a high level Python wrapper to facilitate the key rollover process for zones handled by BIND\&. It uses the BIND commands for manipulating DNSSEC key metadata:
+\fBdnssec\-keygen\fR
+and
+\fBdnssec\-settime\fR\&.
+.PP
+DNSSEC policy can be read from a configuration file (default
+/etc/dnssec\-policy\&.conf), from which the key parameters, publication and rollover schedule, and desired coverage duration for any given zone can be determined\&. This file may be used to define individual DNSSEC policies on a per\-zone basis, or to set a default policy used for all zones\&.
+.PP
+When
+\fBdnssec\-keymgr\fR
+runs, it examines the DNSSEC keys for one or more zones, comparing their timing metadata against the policies for those zones\&. If key settings do not conform to the DNSSEC policy (for example, because the policy has been changed), they are automatically corrected\&.
+.PP
+A zone policy can specify a duration for which we want to ensure the key correctness (\fBcoverage\fR)\&. It can also specify a rollover period (\fBroll\-period\fR)\&. If policy indicates that a key should roll over before the coverage period ends, then a successor key will automatically be created and added to the end of the key series\&.
+.PP
+If zones are specified on the command line,
+\fBdnssec\-keymgr\fR
+will examine only those zones\&. If a specified zone does not already have keys in place, then keys will be generated for it according to policy\&.
+.PP
+If zones are
+\fInot\fR
+specified on the command line, then
+\fBdnssec\-keymgr\fR
+will search the key directory (either the current working directory or the directory set by the
+\fB\-K\fR
+option), and check the keys for all the zones represented in the directory\&.
+.PP
+It is expected that this tool will be run automatically and unattended (for example, by
+\fBcron\fR)\&.
+.SH "OPTIONS"
+.PP
+\-c \fIfile\fR
+.RS 4
+If
+\fB\-c\fR
+is specified, then the DNSSEC policy is read from
+\fBfile\fR\&. (If not specified, then the policy is read from
+/etc/dnssec\-policy\&.conf; if that file doesn\*(Aqt exist, a built\-in global default policy is used\&.)
+.RE
+.PP
+\-f
+.RS 4
+Force: allow updating of key events even if they are already in the past\&. This is not recommended for use with zones in which keys have already been published\&. However, if a set of keys has been generated all of which have publication and activation dates in the past, but the keys have not been published in a zone as yet, then this option can be used to clean them up and turn them into a proper series of keys with appropriate rollover intervals\&.

+.SH "POLICY CONFIGURATION"
+.PP
+The

+file can specify three kinds of policies:
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+\fIPolicy classes\fR
+(\fBpolicy \fR\fB\fIname\fR\fR\fB { \&.\&.\&. };\fR) can be inherited by zone policies or other policy classes; these can be used to create sets of different security profiles\&. For example, a policy class
+\fBnormal\fR
+might specify 1024\-bit key sizes, but a class
+\fBextra\fR
+might specify 2048 bits instead;
+\fBextra\fR
+would be used for zones that had unusually high security needs\&.
+.RE
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+Algorithm policies: (\fBalgorithm\-policy \fR\fB\fIalgorithm\fR\fR\fB { \&.\&.\&. };\fR
+) override default per\-algorithm settings\&. For example, by default, RSASHA256 keys use 2048\-bit key sizes for both KSK and ZSK\&. This can be modified using
+\fBalgorithm\-policy\fR, and the new key sizes would then be used for any key of type RSASHA256\&.

+Zone policies: (\fBzone \fR\fB\fIname\fR\fR\fB { \&.\&.\&. };\fR
+) set policy for a single zone by name\&. A zone policy can inherit a policy class by including a
+\fBpolicy\fR
+option\&. Zone names beginning with digits (i\&.e\&., 0\-9) must be quoted\&.
+.RE
+.PP
+Options that can be specified in policies:
+.PP
+\fBalgorithm\fR
+.RS 4
+The key algorithm\&. If no policy is defined, the default is RSASHA256\&.
+.RE
+.PP
+\fBcoverage\fR
+.RS 4
+The length of time to ensure that keys will be correct; no action will be taken to create new keys to be activated after this time\&. This can be represented as a number of seconds, or as a duration using human\-readable units (examples: "1y" or "6 months")\&. A default value for this option can be set in algorithm policies as well as in policy classes or zone policies\&. If no policy is configured, the default is six months\&.
+.RE

+\fBdirectory\fR
+.RS 4
+Specifies the directory in which keys should be stored\&.
+.RE
+.PP
+\fBkey\-size\fR
+.RS 4
+Specifies the number of bits to use in creating keys\&. Takes two arguments: keytype (eihter "zsk" or "ksk") and size\&. A default value for this option can be set in algorithm policies as well as in policy classes or zone policies\&. If no policy is configured, the default is 1024 bits for DSA keys and 2048 for RSA\&.
+.RE
+.PP
+\fBkeyttl\fR
+.RS 4
+The key TTL\&. If no policy is defined, the default is one hour\&.
+.RE
+.PP
+\fBpost\-publish\fR
+.RS 4
+How long after inactivation a key should be deleted from the zone\&. Note: If
+\fBroll\-period\fR
+is not set, this value is ignored\&. Takes two arguments: keytype (eihter "zsk" or "ksk") and a duration\&. A default value for this option can be set in algorithm policies as well as in policy classes or zone policies\&. The default is one month\&.
+.RE
+.PP
+\fBpre\-publish\fR
+.RS 4
+How long before activation a key should be published\&. Note: If
+\fBroll\-period\fR
+is not set, this value is ignored\&. Takes two arguments: keytype (either "zsk" or "ksk") and a duration\&. A default value for this option can be set in algorithm policies as well as in policy classes or zone policies\&. The default is one month\&.
+.RE
+.PP
+\fBroll\-period\fR
+.RS 4
+How frequently keys should be rolled over\&. Takes two arguments: keytype (eihter "zsk" or "ksk") and a duration\&. A default value for this option can be set in algorithm policies as well as in policy classes or zone policies\&. If no policy is configured, the default is one year for ZSK\*(Aqs\&.

+<a name="id-1.7"></a><h2>DESCRIPTION</h2>
+    <p>
+      <span class="command"><strong>dnssec-keymgr</strong></span> is a high level Python wrapper
+      to facilitate the key rollover process for zones handled by
+      BIND. It uses the BIND commands for manipulating DNSSEC key
+      metadata: <span class="command"><strong>dnssec-keygen</strong></span> and
+      <span class="command"><strong>dnssec-settime</strong></span>.
+    </p>
+    <p>
+      DNSSEC policy can be read from a configuration file (default
+      <code class="filename">/etc/dnssec-policy.conf</code>), from which the key
+      parameters, publication and rollover schedule, and desired
+      coverage duration for any given zone can be determined.  This
+      file may be used to define individual DNSSEC policies on a
+      per-zone basis, or to set a default policy used for all zones.
+    </p>
+    <p>
+      When <span class="command"><strong>dnssec-keymgr</strong></span> runs, it examines the DNSSEC
+      keys for one or more zones, comparing their timing metadata against
+      the policies for those zones.  If key settings do not conform to the
+      DNSSEC policy (for example, because the policy has been changed),
+      they are automatically corrected.
+    </p>
+    <p>
+      A zone policy can specify a duration for which we want to
+      ensure the key correctness (<code class="option">coverage</code>).  It can
+      also specify a rollover period (<code class="option">roll-period</code>).
+      If policy indicates that a key should roll over before the
+      coverage period ends, then a successor key will automatically be
+      created and added to the end of the key series.
+    </p>
+    <p>
+      If zones are specified on the command line,
+      <span class="command"><strong>dnssec-keymgr</strong></span> will examine only those zones.
+      If a specified zone does not already have keys in place, then
+      keys will be generated for it according to policy.
+    </p>
+    <p>
+      If zones are <span class="emphasis"><em>not</em></span> specified on the command
+      line, then <span class="command"><strong>dnssec-keymgr</strong></span> will search the
+      key directory (either the current working directory or the directory
+      set by the <code class="option">-K</code> option), and check the keys for
+      all the zones represented in the directory.
+    </p>
+    <p>
+      It is expected that this tool will be run automatically and
+      unattended (for example, by <span class="command"><strong>cron</strong></span>).

+\fBrndc\fR [\fB\-b\ \fR\fB\fIsource\-address\fR\fR] [\fB\-c\ \fR\fB\fIconfig\-file\fR\fR] [\fB\-k\ \fR\fB\fIkey\-file\fR\fR] [\fB\-s\ \fR\fB\fIserver\fR\fR] [\fB\-p\ \fR\fB\fIport\fR\fR] [\fB\-q\fR] [\fB\-r\fR] [\fB\-V\fR] [\fB\-y\ \fR\fB\fIkey_id\fR\fR] {command}
+.SH "DESCRIPTION"
+.PP
+\fBrndc\fR
+controls the operation of a name server\&. It supersedes the
+\fBndc\fR
+utility that was provided in old BIND releases\&. If
+\fBrndc\fR
+is invoked with no command line options or arguments, it prints a short summary of the supported commands and the available options and their arguments\&.
+.PP
+\fBrndc\fR
+communicates with the name server over a TCP connection, sending commands authenticated with digital signatures\&. In the current versions of
+\fBrndc\fR
+and
+\fBnamed\fR, the only supported authentication algorithms are HMAC\-MD5 (for compatibility), HMAC\-SHA1, HMAC\-SHA224, HMAC\-SHA256 (default), HMAC\-SHA384 and HMAC\-SHA512\&. They use a shared secret on each end of the connection\&. This provides TSIG\-style authentication for the command request and the name server\*(Aqs response\&. All commands sent over the channel must be signed by a key_id known to the server\&.
+.PP
+\fBrndc\fR
+reads a configuration file to determine how to contact the name server and decide what algorithm and key it should use\&.
+.SH "OPTIONS"
+.PP
+\-b \fIsource\-address\fR
+.RS 4
+Use
+\fIsource\-address\fR
+as the source address for the connection to the server\&. Multiple instances are permitted to allow setting of both the IPv4 and IPv6 source addresses\&.
+.RE
+.PP
+\-c \fIconfig\-file\fR
+.RS 4
+Use
+\fIconfig\-file\fR
+as the configuration file instead of the default,
+/etc/rndc\&.conf\&.
+.RE
+.PP
+\-k \fIkey\-file\fR
+.RS 4
+Use
+\fIkey\-file\fR
+as the key file instead of the default,
+/etc/rndc\&.key\&. The key in
+/etc/rndc\&.key
+will be used to authenticate commands sent to the server if the
+\fIconfig\-file\fR
+does not exist\&.
+.RE
+.PP
+\-s \fIserver\fR
+.RS 4
+\fIserver\fR
+is the name or address of the server which matches a server statement in the configuration file for
+\fBrndc\fR\&. If no server is supplied on the command line, the host named by the default\-server clause in the options statement of the
+\fBrndc\fR
+configuration file will be used\&.
+.RE
+.PP
+\-p \fIport\fR
+.RS 4
+Send commands to TCP port
+\fIport\fR
+instead of BIND 9\*(Aqs default control channel port, 953\&.
+.RE
+.PP
+\-q
+.RS 4
+Quiet mode: Message text returned by the server will not be printed except when there is an error\&.
+.RE
+.PP
+\-r
+.RS 4
+Instructs
+\fBrndc\fR
+to print the result code returned by
+\fBnamed\fR
+after executing the requested command (e\&.g\&., ISC_R_SUCCESS, ISC_R_FAILURE, etc)\&.
+.RE
+.PP
+\-V
+.RS 4
+Enable verbose logging\&.
+.RE
+.PP
+\-y \fIkey_id\fR
+.RS 4
+Use the key
+\fIkey_id\fR
+from the configuration file\&.
+\fIkey_id\fR
+must be known by
+\fBnamed\fR
+with the same algorithm and secret string in order for control message validation to succeed\&. If no
+\fIkey_id\fR
+is specified,
+\fBrndc\fR
+will first look for a key clause in the server statement of the server being used, or if no server statement is present for that host, then the default\-key clause of the options statement\&. Note that the configuration file contains shared secrets which are used to send authenticated control commands to name servers\&. It should therefore not have general read or write access\&.
+.RE
+.SH "COMMANDS"
+.PP
+A list of commands supported by
+\fBrndc\fR
+can be seen by running
+\fBrndc\fR
+without arguments\&.
+.PP
+Currently supported commands are:
+.PP
+\fBaddzone \fR\fB\fIzone\fR\fR\fB \fR\fB[\fIclass\fR [\fIview\fR]]\fR\fB \fR\fB\fIconfiguration\fR\fR\fB \fR
+.RS 4
+Add a zone while the server is running\&. This command requires the
+\fBallow\-new\-zones\fR
+option to be set to
+\fByes\fR\&. The
+\fIconfiguration\fR
+string specified on the command line is the zone configuration text that would ordinarily be placed in
+named\&.conf\&.
+.sp
+The configuration is saved in a file called
+\fIname\fR\&.nzf, where
+\fIname\fR
+is the name of the view, or if it contains characters that are incompatible with use as a file name, a cryptographic hash generated from the name of the view\&. When
+\fBnamed\fR
+is restarted, the file will be loaded into the view configuration, so that zones that were added can persist after a restart\&.
+.sp
+This sample
+\fBaddzone\fR
+command would add the zone
+example\&.com
+to the default view:
+.sp
+$\fBrndc addzone example\&.com \*(Aq{ type master; file "example\&.com\&.db"; };\*(Aq\fR
+.sp
+(Note the brackets and semi\-colon around the zone configuration text\&.)
+.sp
+See also
+\fBrndc delzone\fR
+and
+\fBrndc modzone\fR\&.
+.RE
+.PP
+\fBdelzone \fR\fB[\-clean]\fR\fB \fR\fB\fIzone\fR\fR\fB \fR\fB[\fIclass\fR [\fIview\fR]]\fR\fB \fR
+.RS 4
+Delete a zone while the server is running\&.
+.sp
+If the
+\fB\-clean\fR
+argument is specified, the zone\*(Aqs master file (and journal file, if any) will be deleted along with the zone\&. Without the
+\fB\-clean\fR
+option, zone files must be cleaned up by hand\&. (If the zone is of type "slave" or "stub", the files needing to be cleaned up will be reported in the output of the
+\fBrndc delzone\fR
+command\&.)

+A negative trust anchor selectively disables DNSSEC validation for zones that are known to be failing because of misconfiguration rather than an attack\&. When data to be validated is at or below an active NTA (and above any other configured trust anchors),

+.SH "NAME"
+rndc.conf \- rndc configuration file
+.SH "SYNOPSIS"
+.HP \w'\fBrndc\&.conf\fR\ 'u
+\fBrndc\&.conf\fR
+.SH "DESCRIPTION"
+.PP
+rndc\&.conf
+is the configuration file for
+\fBrndc\fR, the BIND 9 name server control utility\&. This file has a similar structure and syntax to
+named\&.conf\&. Statements are enclosed in braces and terminated with a semi\-colon\&. Clauses in the statements are also semi\-colon terminated\&. The usual comment styles are supported:
+.PP
+C style: /* */
+.PP
+C++ style: // to end of line
+.PP
+Unix style: # to end of line
+.PP
+rndc\&.conf
+is much simpler than
+named\&.conf\&. The file uses three statements: an options statement, a server statement and a key statement\&.
+.PP
+The
+\fBoptions\fR
+statement contains five clauses\&. The
+\fBdefault\-server\fR
+clause is followed by the name or address of a name server\&. This host will be used when no name server is given as an argument to
+\fBrndc\fR\&. The
+\fBdefault\-key\fR
+clause is followed by the name of a key which is identified by a
+\fBkey\fR
+statement\&. If no
+\fBkeyid\fR
+is provided on the rndc command line, and no
+\fBkey\fR
+clause is found in a matching
+\fBserver\fR
+statement, this default key will be used to authenticate the server\*(Aqs commands and responses\&. The
+\fBdefault\-port\fR
+clause is followed by the port to connect to on the remote name server\&. If no
+\fBport\fR
+option is provided on the rndc command line, and no
+\fBport\fR
+clause is found in a matching
+\fBserver\fR
+statement, this default port will be used to connect\&. The
+\fBdefault\-source\-address\fR
+and
+\fBdefault\-source\-address\-v6\fR
+clauses which can be used to set the IPv4 and IPv6 source addresses respectively\&.
+.PP
+After the
+\fBserver\fR
+keyword, the server statement includes a string which is the hostname or address for a name server\&. The statement has three possible clauses:
+\fBkey\fR,
+\fBport\fR
+and
+\fBaddresses\fR\&. The key name must match the name of a key statement in the file\&. The port number specifies the port to connect to\&. If an
+\fBaddresses\fR
+clause is supplied these addresses will be used instead of the server name\&. Each address can take an optional port\&. If an
+\fBsource\-address\fR
+or
+\fBsource\-address\-v6\fR
+of supplied then these will be used to specify the IPv4 and IPv6 source addresses respectively\&.
+.PP
+The
+\fBkey\fR
+statement begins with an identifying string, the name of the key\&. The statement has two clauses\&.
+\fBalgorithm\fR
+identifies the authentication algorithm for
+\fBrndc\fR
+to use; currently only HMAC\-MD5 (for compatibility), HMAC\-SHA1, HMAC\-SHA224, HMAC\-SHA256 (default), HMAC\-SHA384 and HMAC\-SHA512 are supported\&. This is followed by a secret clause which contains the base\-64 encoding of the algorithm\*(Aqs authentication key\&. The base\-64 string is enclosed in double quotes\&.
+.PP
+There are two common ways to generate the base\-64 string for the secret\&. The BIND 9 program
+\fBrndc\-confgen\fR
+can be used to generate a random key, or the
+\fBmmencode\fR
+program, also known as
+\fBmimencode\fR, can be used to generate a base\-64 string from known input\&.
+\fBmmencode\fR
+does not ship with BIND 9 but is available on many systems\&. See the EXAMPLE section for sample command lines for each\&.
+.SH "EXAMPLE"
+.PP
+.if n \{\
+.RS 4
+.\}
+.nf
+      options {
+        default\-server  localhost;
+        default\-key     samplekey;
+      };
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+.if n \{\
+.RS 4
+.\}
+.nf
+      server localhost {
+        key             samplekey;
+      };
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+.if n \{\
+.RS 4
+.\}
+.nf
+      server testserver {
+        key		testkey;
+        addresses	{ localhost port 5353; };
+      };
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+.if n \{\
+.RS 4
+.\}
+.nf
+      key samplekey {
+        algorithm       hmac\-sha256;
+        secret          "6FMfj43Osz4lyb24OIe2iGEz9lf1llJO+lz";
+      };
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+.if n \{\
+.RS 4
+.\}
+.nf
+      key testkey {
+        algorithm	hmac\-sha256;
+        secret		"R3HI8P6BKw9ZwXwN3VZKuQ==";
+      };
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+In the above example,
+\fBrndc\fR
+will by default use the server at localhost (127\&.0\&.0\&.1) and the key called samplekey\&. Commands to the localhost server will use the samplekey key, which must also be defined in the server\*(Aqs configuration file with the same name and secret\&. The key statement indicates that samplekey uses the HMAC\-SHA256 algorithm and its secret clause contains the base\-64 encoding of the HMAC\-SHA256 secret enclosed in double quotes\&.
+.PP
+If
+\fBrndc \-s testserver\fR
+is used then
+\fBrndc\fR
+will connect to server on localhost port 5353 using the key testkey\&.
+.PP
+To generate a random secret with
+\fBrndc\-confgen\fR:
+.PP
+\fBrndc\-confgen\fR
+.PP
+A complete
+rndc\&.conf
+file, including the randomly generated key, will be written to the standard output\&. Commented\-out
+\fBkey\fR
+and
+\fBcontrols\fR
+statements for
+named\&.conf
+are also printed\&.
+.PP
+To generate a base\-64 secret with
+\fBmmencode\fR:
+.PP
+\fBecho "known plaintext for a secret" | mmencode\fR
+.SH "NAME SERVER CONFIGURATION"
+.PP
+The name server must be configured to accept rndc connections and to recognize the key specified in the
+rndc\&.conf
+file, using the controls statement in
+named\&.conf\&. See the sections on the
+\fBcontrols\fR
+statement in the BIND 9 Administrator Reference Manual for details\&.

+
+    <p><code class="filename">rndc.conf</code> is the configuration file
+      for <span class="command"><strong>rndc</strong></span>, the BIND 9 name server control
+      utility.  This file has a similar structure and syntax to
+      <code class="filename">named.conf</code>.  Statements are enclosed
+      in braces and terminated with a semi-colon.  Clauses in
+      the statements are also semi-colon terminated.  The usual
+      comment styles are supported:
+    </p>
+    <p>
+      C style: /* */
+    </p>
+    <p>
+      C++ style: // to end of line
+    </p>
+    <p>
+      Unix style: # to end of line
+    </p>
+    <p><code class="filename">rndc.conf</code> is much simpler than
+      <code class="filename">named.conf</code>.  The file uses three
+      statements: an options statement, a server statement
+      and a key statement.
+    </p>
+    <p>
+      The <code class="option">options</code> statement contains five clauses.
+      The <code class="option">default-server</code> clause is followed by the
+      name or address of a name server.  This host will be used when
+      no name server is given as an argument to
+      <span class="command"><strong>rndc</strong></span>.  The <code class="option">default-key</code>
+      clause is followed by the name of a key which is identified by
+      a <code class="option">key</code> statement.  If no
+      <code class="option">keyid</code> is provided on the rndc command line,
+      and no <code class="option">key</code> clause is found in a matching
+      <code class="option">server</code> statement, this default key will be
+      used to authenticate the server's commands and responses.  The
+      <code class="option">default-port</code> clause is followed by the port
+      to connect to on the remote name server.  If no
+      <code class="option">port</code> option is provided on the rndc command
+      line, and no <code class="option">port</code> clause is found in a
+      matching <code class="option">server</code> statement, this default port
+      will be used to connect.
+      The <code class="option">default-source-address</code> and
+      <code class="option">default-source-address-v6</code> clauses which
+      can be used to set the IPv4 and IPv6 source addresses
+      respectively.
+    </p>
+    <p>
+      After the <code class="option">server</code> keyword, the server
+      statement includes a string which is the hostname or address
+      for a name server.  The statement has three possible clauses:
+      <code class="option">key</code>, <code class="option">port</code> and
+      <code class="option">addresses</code>. The key name must match the
+      name of a key statement in the file.  The port number
+      specifies the port to connect to.  If an <code class="option">addresses</code>
+      clause is supplied these addresses will be used instead of
+      the server name.  Each address can take an optional port.
+      If an <code class="option">source-address</code> or <code class="option">source-address-v6</code>
+      of supplied then these will be used to specify the IPv4 and IPv6
+      source addresses respectively.
+    </p>
+    <p>
+      The <code class="option">key</code> statement begins with an identifying
+      string, the name of the key.  The statement has two clauses.
+      <code class="option">algorithm</code> identifies the authentication algorithm
+      for <span class="command"><strong>rndc</strong></span> to use; currently only HMAC-MD5
+      (for compatibility), HMAC-SHA1, HMAC-SHA224, HMAC-SHA256
+      (default), HMAC-SHA384 and HMAC-SHA512 are
+      supported.  This is followed by a secret clause which contains
+      the base-64 encoding of the algorithm's authentication key.  The
+      base-64 string is enclosed in double quotes.
+    </p>
+    <p>
+      There are two common ways to generate the base-64 string for the
+      secret.  The BIND 9 program <span class="command"><strong>rndc-confgen</strong></span>
+      can
+      be used to generate a random key, or the
+      <span class="command"><strong>mmencode</strong></span> program, also known as
+      <span class="command"><strong>mimencode</strong></span>, can be used to generate a
+      base-64
+      string from known input.  <span class="command"><strong>mmencode</strong></span> does
+      not
+      ship with BIND 9 but is available on many systems.  See the
+      EXAMPLE section for sample command lines for each.

+	    will be retained.
+	  </para>
+	  <para>
+	    <command>rndc signing -nsec3param</command> sets
+	    the NSEC3 parameters for a zone.  This is the
+	    only supported mechanism for using NSEC3 with
+	    <command>inline-signing</command> zones.
+	    Parameters are specified in the same format as
+	    an NSEC3PARAM resource record: hash algorithm,
+	    flags, iterations, and salt, in that order.
+	  </para>
+	  <para>
+	    Currently, the only defined value for hash algorithm
+	    is <literal>1</literal>, representing SHA-1.
+	    The <option>flags</option> may be set to
+	    <literal>0</literal> or <literal>1</literal>,
+	    depending on whether you wish to set the opt-out
+	    bit in the NSEC3 chain.  <option>iterations</option>
+	    defines the number of additional times to apply
+	    the algorithm when generating an NSEC3 hash.  The
+	    <option>salt</option> is a string of data expressed
+	    in hexadecimal, a hyphen (`-') if no salt is
+	    to be used, or the keyword <literal>auto</literal>,
+	    which causes <command>named</command> to generate a
+	    random 64-bit salt.
+	  </para>
+	  <para>
+	    So, for example, to create an NSEC3 chain using
+	    the SHA-1 hash algorithm, no opt-out flag,
+	    10 iterations, and a salt value of "FFFF", use:
+	    <command>rndc signing -nsec3param 1 0 10 FFFF <replaceable>zone</replaceable></command>.
+	    To set the opt-out flag, 15 iterations, and no
+	    salt, use:
+	    <command>rndc signing -nsec3param 1 1 15 - <replaceable>zone</replaceable></command>.
+	  </para>
+	  <para>
+	    <command>rndc signing -nsec3param none</command>
+	    removes an existing NSEC3 chain and replaces it
+	    with NSEC.
+	  </para>
+	  <para>
+	    <command>rndc signing -serial value</command> sets
+	    the serial number of the zone to value.  If the value
+	    would cause the serial number to go backwards it will
+	    be rejected.  The primary use is to set the serial on
+	    inline signed zones.

+
+    <p><span class="command"><strong>rndc</strong></span>
+      controls the operation of a name
+      server.  It supersedes the <span class="command"><strong>ndc</strong></span> utility
+      that was provided in old BIND releases.  If
+      <span class="command"><strong>rndc</strong></span> is invoked with no command line
+      options or arguments, it prints a short summary of the
+      supported commands and the available options and their
+      arguments.
+    </p>
+    <p><span class="command"><strong>rndc</strong></span>
+      communicates with the name server over a TCP connection, sending
+      commands authenticated with digital signatures.  In the current
+      versions of
+      <span class="command"><strong>rndc</strong></span> and <span class="command"><strong>named</strong></span>,
+      the only supported authentication algorithms are HMAC-MD5
+      (for compatibility), HMAC-SHA1, HMAC-SHA224, HMAC-SHA256
+      (default), HMAC-SHA384 and HMAC-SHA512.
+      They use a shared secret on each end of the connection.
+      This provides TSIG-style authentication for the command
+      request and the name server's response.  All commands sent
+      over the channel must be signed by a key_id known to the
+      server.
+    </p>
+    <p><span class="command"><strong>rndc</strong></span>
+      reads a configuration file to
+      determine how to contact the name server and decide what
+      algorithm and key it should use.

+<dd>
+	  <p>
+	    Add a zone while the server is running.  This
+	    command requires the
+	    <span class="command"><strong>allow-new-zones</strong></span> option to be set
+	    to <strong class="userinput"><code>yes</code></strong>.  The
+	    <em class="replaceable"><code>configuration</code></em> string

+	  </p>
+	  <p>
+	    The configuration is saved in a file called

+	  <p>
+	    This sample <span class="command"><strong>addzone</strong></span> command

+	    If data can be validated, then the NTA is regarded as

+	    Parameters are specified in the same format as
+	    an NSEC3PARAM resource record: hash algorithm,
+	    flags, iterations, and salt, in that order.
+	  </p>
+	  <p>
+	    Currently, the only defined value for hash algorithm
+	    is <code class="literal">1</code>, representing SHA-1.

+	    bit in the NSEC3 chain.  <code class="option">iterations</code>
+	    defines the number of additional times to apply
+	    the algorithm when generating an NSEC3 hash.  The
+	    <code class="option">salt</code> is a string of data expressed
+	    in hexadecimal, a hyphen (`-') if no salt is
+	    to be used, or the keyword <code class="literal">auto</code>,
+	    which causes <span class="command"><strong>named</strong></span> to generate a
+	    random 64-bit salt.
+	  </p>
+	  <p>
+	    So, for example, to create an NSEC3 chain using
+	    the SHA-1 hash algorithm, no opt-out flag,
+	    10 iterations, and a salt value of "FFFF", use:
+	    <span class="command"><strong>rndc signing -nsec3param 1 0 10 FFFF <em class="replaceable"><code>zone</code></em></strong></span>.
+	    To set the opt-out flag, 15 iterations, and no

+	    <span class="command"><strong>rndc signing -nsec3param 1 1 15 - <em class="replaceable"><code>zone</code></em></strong></span>.
+	  </p>
+	  <p>
+	    <span class="command"><strong>rndc signing -nsec3param none</strong></span>
+	    removes an existing NSEC3 chain and replaces it
+	    with NSEC.
+	  </p>
+	  <p>
+	    <span class="command"><strong>rndc signing -serial value</strong></span> sets
+	    the serial number of the zone to value.  If the value

+"pkcs11-hmacmd5" is here to check for the presence of a known bug in
+the Thales nCipher PKCS#11 provider library.  To test for the bug, use
+pkcs11-hmacmd5 to hash a test vector from RFC 2104, and determine
+whether the resulting digest is is correct.  For instance:
+
+    echo -n "Hi There" | \
+        ./pkcs11-hmacmd5 -p <PIN> -k '0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b'
+
+...must return "9294727a3638bb1c13f48ef8158bfc9d".
+
+If any other value is returned, then the provider library is buggy,
+and theflag PK11_MD5_HMAC_REPLACE must be defined in
+lib/isc/include/pk11/site.h
+However, if the correct value is returned, then it is safe to turn
+off PK11_MD5_HMAC_REPLACE. (It is on by default.)

+
+Introduction
+===
+This directory holds a simple test environment for running bind9 system tests
+involving multiple name servers.
+
+With the exception of "common" (which holds configuration information common to
+multiple tests) and "win32" (which holds files needed to run the tests in a
+Windows environment), each directory holds a set of scripts and configuration
+files to test different parts of BIND.  The directories are named for the
+aspect of BIND they test, for example:
+
+  dnssec/       DNSSEC tests
+  forward/      Forwarding tests
+  glue/         Glue handling tests
+
+etc.
+
+Typically each set of tests sets up 2-5 name servers and then performs one or
+more tests against them.  Within the test subdirectory, each name server has a
+separate subdirectory containing its configuration data.  These subdirectories
+are named "nsN" or "ansN" (where N is a number between 1 and 8, e.g. ns1, ans2
+etc.)
+
+The tests are completely self-contained and do not require access to the real
+DNS.  Generally, one of the test servers (usually ns1) is set up as a root
+nameserver and is listed in the hints file of the others.
+
+
+Preparing to Run the Tests
+===
+To enable all servers to run on the same machine, they bind to separate virtual
+IP addresses on the loopback interface.  ns1 runs on 10.53.0.1, ns2 on
+10.53.0.2, etc.  Before running any tests, you must set up these addresses by
+running the command
+
+    sh ifconfig.sh up
+
+as root.  The interfaces can be removed by executing the command:
+
+    sh ifconfig.sh down
+
+... also as root.
+
+The servers use unprivileged ports (above 1024) instead of the usual port 53,
+so they can be run without root privileges once the interfaces have been set
+up.
+
+
+Note for MacOS Users
+---
+If you wish to make the interfaces survive across reboots, copy
+org.isc.bind.system and org.isc.bind.system.plist to /Library/LaunchDaemons
+then run
+
+    launchctl load /Library/LaunchDaemons/org.isc.bind.system.plist
+
+... as root.
+
+
+Running the System Tests
+===
+
+Running an Individual Test
+---
+The tests can be run individually using the following command:
+
+    sh run.sh [flags] <test-name> [<test-arguments>]
+
+e.g.
+
+    sh run.sh [flags] notify
+
+Optional flags are:
+
+    -k              Keep servers running after the test completes.  Each test
+                    usually starts a number of nameservers, either instances
+                    of the "named" being tested, or custom servers (written in
+                    Python or Perl) that feature test-specific behavior.  The
+                    servers are automatically started before the test is run
+                    and stopped after it ends.  This flag leaves them running
+                    at the end of the test, so that additional queries can be
+                    sent by hand.  To stop the servers afterwards, use the
+                    command "sh stop.sh <test-name>".
+
+    -n              Noclean - do not remove the output files if the test
+                    completes successfully.  By default, files created by the
+                    test are deleted if it passes;  they are not deleted if the
+                    test fails.
+
+    -p <number>     Sets the range of ports used by the test.  A block of 100
+                    ports is available for each test, the number given to the
+                    "-p" switch being the number of the start of that block
+                    (e.g. "-p 7900" will mean that the test is able to use
+                    ports 7900 through 7999).  If not specified, the test will
+                    have ports 5000 to 5099 available to it.
+
+    -r              The "runall" flag.  This is related to cleaning up after
+                    the tests (see "Maintenance Notes" below).  If specified,
+                    it prevents a copy of the test's output listing from being
+                    deleted when the directory is cleaned up after the test
+                    completes.  (The test's output listing comprises messages
+                    produced by the test during its execution; it does not
+                    include the output files produced by utilities such as
+                    "dig" or "rndc", nor any logging output from named itself.)
+                    It is usually only used when "run.sh" is being called
+                    during a run of the entire test suite.  Note that if "-n"
+                    is specified on the "run.sh" command line, the test output
+                    is retained even if this option is omitted.
+
+Arguments are:
+
+    test-name       Mandatory.  The name of the test, which is the name of the
+                    subdirectory in bin/tests/system holding the test files.
+
+    test-arguments  Optional arguments that are passed to each of the test's
+                    scripts.
+
+
+Running All The System Tests
+---
+To run all the system tests, enter the command:
+
+    sh runall.sh [-c] [-n] [numproc]
+
+The optional flag "-c" forces colored output (by default system test output is
+not printed in color due to run.sh being piped through "tee").
+
+The optional flag "-n" has the same effect as it does for "run.sh" - it causes
+the retention of all output files from all tests.
+
+The optional "numproc" argument specifies the maximum number of tests that can
+run in parallel.  The default is 1, which means that all of the tests run
+sequentially.  If greater than 1, up to "numproc" tests will run simultaneously,
+new tests being started as tests finish.  Each test will get a unique set of
+ports, so there is no danger of tests interfering with one another.  Parallel
+running will reduce the total time taken to run the BIND system tests, but will
+mean that the output from all the tests sent to the screen will be mixed up
+with one another.  However, the systests.output file produced at the end of the
+run (in the bin/tests/system directory) will contain the output from each test
+in sequential order.
+
+Note that it is not possible to pass arguments to tests though the "runall.sh"
+script.
+
+A run of all the system tests can also be initiated via make:
+
+    make [-j numproc] test
+
+In this case, retention of the output files after a test completes successfully
+is specified by setting the environment variable SYSTEMTEST_NO_CLEAN to 1 prior
+to running make, e.g.
+
+    SYSTEMTEST_NO_CLEAN=1 make [-j numproc] test
+
+while setting environment variable SYSTEMTEST_FORCE_COLOR to 1 forces system
+test output to be printed in color.
+
+
+Running Multiple System Test Suites Simultaneously
+---
+In some cases it may be desirable to have multiple instances of the system test
+suite running simultaneously (e.g. from different terminal windows).  To do
+this:
+
+1. Each installation must have its own directory tree.  The system tests create
+files in the test directories, so separate directory trees are required to
+avoid interference between the same test running in the different
+installations.
+
+2. For one of the test suites, the starting port number must be specified by
+setting the environment variable STARTPORT before starting the test suite.
+Each test suite comprises about 100 tests, each being allocated a set of 100
+ports.  The port ranges for each test are allocated sequentially, so each test
+suite requires about 10,000 ports to itself.  By default, the port allocation
+starts at 5,000.  So the following set of commands:
+
+    Terminal Window 1:
+        cd <installation-1>/bin/tests/system
+        sh runall.sh 4
+
+    Terminal Window 2:
+        cd <installation-2>/bin/tests/system
+        STARTPORT=20000 sh runall.sh 4
+
+... will start the test suite for installation-1 using the default base port
+of 5,000, so the test suite will use ports 5,000 through 15,000 (or there
+abouts).  The use of "STARTPORT=20000" to prefix the run of the test suite for
+installation-2 will mean the test suite uses ports 20,000 through 30,000 or so.
+
+
+Format of Test Output
+---
+All output from the system tests is in the form of lines with the following
+structure:
+
+    <letter>:<test-name>:<message> [(<number>)]
+
+e.g.
+
+    I:catz:checking that dom1.example is not served by master (1)
+
+The meanings of the fields are as follows:
+
+<letter>
+This indicates the type of message.  This is one of:
+
+    S   Start of the test
+    A   Start of test (retained for backwards compatibility)
+    T   Start of test (retained for backwards compatibility)
+    E   End of the test
+    I   Information.  A test will typically output many of these messages
+        during its run, indicating test progress.  Note that such a message may
+        be of the form "I:testname:failed", indicating that a sub-test has
+        failed.
+    R   Result.  Each test will result in one such message, which is of the
+        form:
+
+                R:<test-name>:<result>
+
+        where <result> is one of:
+
+            PASS        The test passed
+            FAIL        The test failed
+            SKIPPED     The test was not run, usually because some
+                        prerequisites required to run the test are missing.
+            UNTESTED    The test was not run for some other reason, e.g. a
+                        prerequisite is available but is not compatible with
+                        the platform on which the test is run.
+
+<test-name>
+This is the name of the test from which the message emanated, which is also the
+name of the subdirectory holding the test files.
+
+<message>
+This is text output by the test during its execution.
+
+(<number>)
+If present, this will correlate with a file created by the test.  The tests
+execute commands and route the output of each command to a file.  The name of
+this file depends on the command and the test, but will usually be of the form:
+
+    <command>.out.<suffix><number>
+
+e.g. nsupdate.out.test28, dig.out.q3.  This aids diagnosis of problems by
+allowing the output that caused the problem message to be identified.
+
+
+Re-Running the Tests
+---
+If there is a requirement to re-run a test (or the entire test suite), the
+files produced by the tests should be deleted first.  Normally, these files are
+deleted if the test succeeds but are retained on error.
+
+Deletion of files produced by an individual test can be done with the command:
+
+    sh clean.sh [-r] <test-name>
+
+The optional flag is:
+
+    -r              The "runall" flag.  This is related to cleaning up after
+                    the tests (see "Maintenance Notes" below).  If specified,
+                    it prevents a copy of the test's output listing from being
+                    deleted when the directory is cleaned after the test
+                    completes.
+
+Deletion of the files produced by the set of tests (e.g. after the execution
+of "runall.sh") can be deleted by the command:
+
+    sh cleanall.sh
+
+or
+
+    make testclean
+
+(Note that the Makefile has two other targets for cleaning up files: "clean"
+will delete all the files produced by the tests, as well as the object and
+executable files used by the tests.  "distclean" does all the work of "clean"
+as well as deleting configuration files produced by "configure".)
+
+
+Developer Notes
+===
+This section is intended for developers writing new tests.
+
+
+Overview
+---
+As noted above, each test is in a separate directory.  To interact with the
+test framework, the directories contain the following standard files:
+
+prereq.sh   Run at the beginning to determine whether the test can be run at
+            all; if not, we see a result of R:SKIPPED or R:UNTESTED.  This file
+            is optional: if not present, the test is assumed to have all its
+            prerequisites met.
+
+setup.sh    Run after prereq.sh, this sets up the preconditions for the tests.
+            Although optional, virtually all tests will require such a file to
+            set up the ports they should use for the test.
+
+tests.sh    Runs the actual tests.  This file is mandatory.
+
+clean.sh    Run at the end to clean up temporary files, but only if the test
+            was completed successfully and its running was not inhibited by the
+	    "-n" switch being passed to "run.sh".  Otherwise the temporary
+	    files are left in place for inspection.
+
+ns<N>       These subdirectories contain test name servers that can be queried
+	    or can interact with each other.  The value of N indicates the
+	    address the server listens on: for example, ns2 listens on
+	    10.53.0.2, and ns4 on 10.53.0.4.  All test servers use an
+	    unprivileged port, so they don't need to run as root.  These
+	    servers log at the highest debug level and the log is captured in
+	    the file "named.run".
+
+ans<N>      Like ns[X], but these are simple mock name servers implemented in
+            Perl or Python.  They are generally programmed to misbehave in ways
+            named would not so as to exercise named's ability to interoperate
+            with badly behaved name servers.
+
+
+Port Usage
+---
+In order for the tests to run in parallel, each test requires a unique set of
+ports.  These are specified by the "-p" option passed to "run.sh", which sets
+environment variables that the scripts listed above can reference.
+
+The convention used in the system tests is that the number passed is the start
+of a range of 100 ports.  The test is free to use the ports as required,
+although the first ten ports in the block are named and generally tests use the
+named ports for their intended purpose.  The names of the environment variables
+are:
+
+    PORT                     Number to be used for the query port.
+    CONTROLPORT              Number to be used as the RNDC control port.
+    EXTRAPORT1 - EXTRAPORT8  Eight port numbers that can be used as needed.
+
+Two other environment variables are defined:
+
+    LOWPORT                  The lowest port number in the range.
+    HIGHPORT                 The highest port number in the range.
+
+Since port ranges usually start on a boundary of 10, the variables are set such
+that the last digit of the port number corresponds to the number of the
+EXTRAPORTn variable.  For example, if the port range were to start at 5200, the
+port assignments would be:
+
+    PORT = 5200
+    EXTRAPORT1 = 5201
+        :
+    EXTRAPORT8 = 5208
+    CONTROLPORT = 5209
+    LOWPORT = 5200
+    HIGHPORT = 5299
+
+When running tests in parallel (i.e. giving a value of "numproc" greater than 1
+in the "make" or "runall.sh" commands listed above), it is guaranteed that each
+test will get a set of unique port numbers.
+
+
+Writing a Test
+---
+The test framework requires up to four shell scripts (listed above) as well as
+a number of nameserver instances to run.  Certain expectations are put on each
+script:
+
+
+General
+---
+1. Each of the four scripts will be invoked with the command
+
+    (cd <test-directory> ; sh <script> [<arguments>] )
+
+... so that working directory when the script starts executing is the test
+directory.
+
+2. Arguments can be only passed to the script if the test is being run as a
+one-off with "run.sh".  In this case, everything on the command line after the
+name of the test is passed to each script.  For example, the command:
+
+    sh run.sh -p 12300 mytest -D xyz
+
+... will run "mytest" with a port range of 12300 to 12399.  Each of the
+framework scripts provided by the test will be invoked using the remaining
+arguments, e.g.:
+
+   (cd mytest ; sh prereq.sh -D xyz)
+   (cd mytest ; sh setup.sh -D xyz)
+   (cd mytest ; sh tests.sh -D xyz)
+   (cd mytest ; sh clean.sh -D xyz)
+
+No arguments will be passed to the test scripts if the test is run as part of
+a run of the full test suite (e.g. the tests are started with "runall.sh").
+
+3.  Each script should start with the following lines:
+
+    SYSTEMTESTTOP=..
+    . $SYSTEMTESTTOP/conf.sh
+
+"conf.sh" defines a series of environment variables together with functions
+useful for the test scripts. (conf.sh.win32 is the Windows equivalent of this
+file.)
+
+
+prereq.sh
+---
+As noted above, this is optional.  If present, it should check whether specific
+software needed to run the test is available and/or whether BIND has been
+configured with the appropriate options required.
+
+    * If the software required to run the test is present and the BIND
+      configure options are correct, prereq.sh should return with a status code
+      of 0.
+
+    * If the software required to run the test is not available and/or BIND
+      has not been configured with the appropriate options, prereq.sh should
+      return with a status code of 1.
+
+    * If there is some other problem (e.g. prerequisite software is available
+      but is not properly configured), a status code of 255 should be returned.
+
+
+setup.sh
+---
+This is responsible for setting up the configuration files used in the test.
+
+To cope with the varying port number, ports are not hard-coded into
+configuration files (or, for that matter, scripts that emulate nameservers).
+Instead, setup.sh is responsible for editing the configuration files to set the
+port numbers.
+
+To do this, configuration files should be supplied in the form of templates
+containing tokens identifying ports.  The tokens have the same name as the
+environment variables listed above, but are prefixed and suffixed by the "@"
+symbol.  For example, a fragment of a configuration file template might look
+like:
+
+    controls {
+        inet 10.53.0.1 port @CONTROLPORT@ allow { any; } keys { rndc_key; };
+    };
+
+    options {
+        query-source address 10.53.0.1;
+        notify-source 10.53.0.1;
+        transfer-source 10.53.0.1;
+        port @PORT@;
+        allow-new-zones yes;
+    };
+
+setup.sh should copy the template to the desired filename using the
+"copy_setports" shell function defined in "conf.sh", i.e.
+
+    copy_setports ns1/named.conf.in ns1/named.conf
+
+This replaces the tokens @PORT@, @CONTROLPORT@, @EXTRAPORT1@ through
+@EXTRAPORT8@ with the contents of the environment variables listed above.
+setup.sh should do this for all configuration files required when the test
+starts.
+
+("setup.sh" should also use this method for replacing the tokens in any Perl or
+Python name servers used in the test.)
+
+
+tests.sh
+---
+This is the main test file and the contents depend on the test.  The contents
+are completely up to the developer, although most test scripts have a form
+similar to the following for each sub-test:
+
+    1. n=`expr $n + 1`
+    2. echo_i "prime cache nodata.example ($n)"
+    3. ret=0
+    4. $DIG -p ${PORT} @10.53.0.1 nodata.example TXT > dig.out.test$n
+    5. grep "status: NOERROR" dig.out.test$n > /dev/null || ret=1
+    6. grep "ANSWER: 0," dig.out.test$n > /dev/null || ret=1
+    7. if [ $ret != 0 ]; then echo_i "failed"; fi
+    8. status=`expr $status + $ret`
+
+1.  Increment the test number "n" (initialized to zero at the start of the
+    script).
+
+2.  Indicate that the sub-test is about to begin.  Note that "echo_i" instead
+    of "echo" is used.  echo_i is a function defined in "conf.sh" which will
+    prefix the message with "I:<testname>:", so allowing the output from each
+    test to be identified within the output.  The test number is included in
+    the message in order to tie the sub-test with its output.
+
+3. Initialize return status.
+
+4 - 6. Carry out the sub-test.  In this case, a nameserver is queried (note
+    that the port used is given by the PORT environment variable, which was set
+    by the inclusion of the file "conf.sh" at the start of the script).  The
+    output is routed to a file whose suffix includes the test number.  The
+    response from the server is examined and, in this case, if the required
+    string is not found, an error is indicated by setting "ret" to 1.
+
+7.  If the sub-test failed, a message is printed. "echo_i" is used to print
+    the message to add the prefix "I:<test-name>:" before it is output.
+
+8.  "status", used to track how many of the sub-tests have failed, is
+    incremented accordingly.  The value of "status" determines the status
+    returned by "tests.sh", which in turn determines whether the framework
+    prints the PASS or FAIL message.
+
+Regardless of this, rules that should be followed are:
+
+a.  Use the environment variables set by conf.sh to determine the ports to use
+    for sending and receiving queries.
+
+b.  Use a counter to tag messages and to associate the messages with the output
+    files.
+
+c.  Store all output produced by queries/commands into files.  These files
+    should be named according to the command that produced them, e.g. "dig"
+    output should be stored in a file "dig.out.<suffix>", the suffix being
+    related to the value of the counter.
+
+d.  Use "echo_i" to output informational messages.
+
+e.  Retain a count of test failures and return this as the exit status from
+    the script.
+
+
+clean.sh
+---
+The inverse of "setup.sh", this is invoked by the framework to clean up the
+test directory.  It should delete all files that have been created by the test
+during its run.
+
+
+Starting Nameservers
+---
+As noted earlier, a system test will involve a number of nameservers.  These
+will be either instances of named, or special servers written in a language
+such as Perl or Python.
+
+For the former, the version of "named" being run is that in the "bin/named"
+directory in the tree holding the tests (i.e. if "make test" is being run
+immediately after "make", the version of "named" used is that just built).  The
+configuration files, zone files etc. for these servers are located in
+subdirectories of the test directory named "nsN", where N is a small integer.
+The latter are special nameservers, mostly used for generating deliberately bad
+responses, located in subdirectories named "ansN" (again, N is an integer).
+In addition to configuration files, these directories should hold the
+appropriate script files as well.
+
+Note that the "N" for a particular test forms a single number space, e.g. if
+there is an "ns2" directory, there cannot be an "ans2" directory as well.
+Ideally, the directory numbers should start at 1 and work upwards.
+
+When running a test, the servers are started using "start.sh" (which is nothing
+more than a wrapper for start.pl).  The options for "start.pl" are documented
+in the header for that file, so will not be repeated here.  In summary, when
+invoked by "run.sh", start.pl looks for directories named "nsN" or "ansN" in
+the test directory and starts the servers it finds there.
+
+
+"named" Command-Line Options
+---
+By default, start.pl starts a "named" server with the following options:
+
+    -c named.conf   Specifies the configuration file to use (so by implication,
+                    each "nsN" nameserver's configuration file must be called
+                    named.conf).
+
+    -d 99           Sets the maximum debugging level.
+
+    -D <name>       The "-D" option sets a string used to identify the
+                    nameserver in a process listing.  In this case, the string
+                    is the name of the subdirectory.
+
+    -g              Runs the server in the foreground and logs everything to
+                    stderr.
+
+    -m record,size,mctx
+                    Turns on these memory usage debugging flags.
+
+    -U 4            Uses four listeners.
+
+    -X named.lock   Acquires a lock on this file in the "nsN" directory, so
+                    preventing multiple instances of this named running in this
+                    directory (which could possibly interfere with the test).
+
+In addition, start.pl also sets the following undocumented flag:
+
+    -T clienttest   Makes clients single-shot with their own memory context.
+
+All output is sent to a file called "named.run" in the nameserver directory.
+
+The options used to start named can be altered.  There are three ways of doing
+this.  "start.pl" checks the methods in a specific order: if a check succeeds,
+the options are set and any other specification is ignored.  In order, these
+are:
+
+1. Specifying options to "start.sh"/"start.pl" after the name of the test
+directory, e.g.
+
+    sh start.sh reclimit ns1 -- "-c n.conf -d 43"
+
+(This is only really useful when running tests interactively.)
+
+2. Including a file called "named.args" in the "nsN" directory.  If present,
+the contents of the first non-commented, non-blank line of the file are used as
+the named command-line arguments.  The rest of the file is ignored.
+
+3. Tweaking the default command line arguments with "-T" options.  This flag is
+used to alter the behavior of BIND for testing and is not documented in the
+ARM.  The "clienttest" option has already been mentioned, but the presence of
+certain files in the "nsN" directory adds flags to the default command line
+(the content of the files is irrelevant - it is only the presence that counts):
+
+    named.noaa       Appends "-T noaa" to the command line, which causes
+                     "named" to never set the AA bit in an answer.
+
+    named.dropedns   Adds "-T dropedns" to the command line, which causes
+                     "named" to recognise EDNS options in messages, but drop
+                     messages containing them.
+
+    named.maxudp1460 Adds "-T maxudp1460" to the command line, setting the
+                     maximum UDP size handled by named to 1460.
+
+    named.maxudp512  Adds "-T maxudp512" to the command line, setting the
+                     maximum UDP size handled by named to 512.
+
+    named.noedns     Appends "-T noedns" to the command line, which disables
+                     recognition of EDNS options in messages.
+
+    named.notcp      Adds "-T notcp", which disables TCP in "named".
+
+    named.soa        Appends "-T nosoa" to the command line, which disables
+                     the addition of SOA records to negative responses (or to
+                     the additional section if the response is triggered by RPZ
+                     rewriting).
+
+
+Starting Other Nameservers
+---
+In contrast to "named", nameservers written in Perl or Python (whose script
+file should have the name "ans.pl" or "ans.py" respectively) are started with a
+fixed command line.  In essence, the server is given the address and nothing
+else.
+
+(This is not strictly true: Python servers are provided with the number of the
+query port to use.  Altering the port used by Perl servers currently requires
+creating a template file containing the "@PORT@" token, and having "setup.sh"
+substitute the actual port being used before the test starts.)
+
+
+Stopping Nameservers
+---
+As might be expected, the test system stops nameservers with the script
+"stop.sh", which is little more than a wrapper for "stop.pl".  Like "start.pl",
+the options available are listed in the file's header and will not be repeated
+here.
+
+In summary though, the nameservers for a given test, if left running by
+specifying the "-k" flag to "run.sh" when the test is started, can be stopped
+by the command:
+
+    sh stop.sh <test-name> [server]
+
+... where if the server (e.g. "ns1", "ans3") is not specified, all servers
+associated with the test are stopped.
+
+
+Adding a Test to the System Test Suite
+---
+Once a test has been created, the following files should be edited:
+
+* conf.sh.in  The name of the test should be added to the PARALLELDIRS or
+SEQUENTIALDIRS variables as appropriate.  The former is used for tests that
+can run in parallel with other tests, the latter for tests that are unable to
+do so.
+
+* conf.sh.win32 This is the Windows equivalent of conf.sh.in.  The name of the
+test should be added to the PARALLELDIRS or SEQUENTIALDIRS variables as
+appropriate.
+
+* Makefile.in The name of the test should be added to one of the the PARALLEL
+or SEQUENTIAL variables.
+
+(It is likely that a future iteration of the system test suite will remove the
+need to edit multiple files to add a test.)
+
+
+Valgrind
+---
+When running system tests, named can be run under Valgrind.  The output from
+Valgrind are sent to per-process files that can be reviewed after the test has
+completed.  To enable this, set the USE_VALGRIND environment variable to
+"helgrind" to run the Helgrind tool, or any other value to run the Memcheck
+tool.  To use "helgrind" effectively, build BIND with --disable-atomic.
+
+
+Maintenance Notes
+===
+This section is aimed at developers maintaining BIND's system test framework.
+
+Notes on Parallel Execution
+---
+Although execution of an individual test is controlled by "run.sh", which
+executes the above shell scripts (and starts the relevant servers) for each
+test, the running of all tests in the test suite is controlled by the Makefile.
+("runall.sh" does little more than invoke "make" on the Makefile.)
+
+All system tests are capable of being run in parallel.  For this to work, each
+test needs to use a unique set of ports.  To avoid the need to define which
+tests use which ports (and so risk port clashes as further tests are added),
+the ports are assigned when the tests are run.  This is achieved by having the
+"test" target in the Makefile depend on "parallel.mk".  That file is created
+when "make check" is run, and contains a target for each test of the form:
+
+    <test-name>:
+        @$(SHELL) run.sh -r -p <baseport> <test-name>
+
+The <baseport> is unique and the values of <baseport> for each test are
+separated by at least 100 ports.
+
+
+Cleaning Up From Tests
+---
+When a test is run, files are created in the test directory.  These files fall
+into three categories:
+
+1. Files generated by the test itself, e.g. output from "dig" and "rndc".
+
+2. Files produced by named which may not be cleaned up if named exits
+abnormally, e.g. core files, PID files etc.
+
+3. The file "test.output" containing the text written to stdout by the test.
+This is only produced when the test is run as part of the entire test suite
+(e.g. via "runall.sh").
+
+If the test fails, all these files are retained.  But if the test succeeds,
+they are cleaned up at different times:
+
+1. Files generated by the test itself are cleaned up by the test's own
+"clean.sh".  This is called from the system's "clean.sh", which in turn is
+called from "run.sh".
+
+2. Files that may not be cleaned up if named exits abnormally are removed
+by the system's "clean.sh".
+
+3. "test.output" files are deleted when the test suite ends.  At this point,
+the file "testsummary.sh" is called which concatenates all the "test.output"
+files into a single "systest.output" file before deleting them.
+
+A complication arises with the "test.output" file however:
+
+1. "clean.sh" is called by "run.sh" if the test ends successfully.  For
+this reason, "clean.sh" cannot delete "test.output" as, if the test is
+being run as part of a test suite, the file must be retained.
+
+2. If the deletion of "test.output" were to be solely the responsibility of
+"testsummary.sh", should a test suite terminate abnormally, cleaning up a test
+directory with "sh clean.sh <test-directory>" would leave the file present.
+
+3. An additional step could be added to "cleanall.sh" (which calls the
+system's "clean.sh" for each test) to remove the "test.output" file.  However,
+although the file would be deleted should all test directories be cleaned,
+it would still mean that running "clean.sh" on a particular test directory
+could leave the file present.
+
+To get round this, the system's "clean.sh" script takes an optional flag, "-r"
+(the "runall" flag).  When the test suite is run, each invocation of "run.sh"
+is passed the runall flag.  In turn, "run.sh" passes the flag to "clean.sh",
+which causes that script not to delete the "tests.output" file.  In other
+words, when the system's "clean.sh" is invoked standalone on a test directory
+(or as part of a run of "cleanall.sh"), it will delete the "test.output" if it
+is present.  When invoked during a run of the entire test suite, it won't.

+# Test of allow-query statement.
+# allow-query takes an address match list and can be included in either the
+# options statement or in the zone statement.  This test assumes that the
+# acl tests cover the details of the address match list and uses a limited
+# number of address match test cases to ensure that allow-query finds the
+# expected match.
+# Test list:
+# In options:
+# default (any), any, none, [localhost, localnets],
+# allowed address, not allowed address, denied address,
+# allowed key, not allowed key, denied key
+# allowed acl, not allowed acl, denied acl (acls pointing to addresses)
+#
+# Each of these tests requires changing to a new configuration
+# file and using rndc to update the server
+#
+# In view, with nothing in options (default to any)
+# default (any), any, none, [localhost, localnets],
+# allowed address, not allowed address, denied address,
+# allowed key, not allowed key, denied key

+#
+# This is the name server from hell.  It provides canned
+# responses based on pattern matching the queries, and
+# can be reprogrammed on-the-fly over a TCP connection.
+#
+# The server listens for queries on port 5300 (or PORT).
+#
+# The server listens for control connections on port 5301 (or EXTRAPORT1).
+#
+# A control connection is a TCP stream of lines like
+#
+#  /pattern/
+#  name ttl type rdata
+#  name ttl type rdata
+#  ...
+#  /pattern/
+#  name ttl type rdata
+#  name ttl type rdata
+#  ...
+#
+# There can be any number of patterns, each associated
+# with any number of response RRs.  Each pattern is a
+# Perl regular expression.  If an empty pattern ("//") is
+# received, the server will ignore all incoming queries (TCP
+# connections will still be accepted, but both UDP queries
+# and TCP queries will not be responded to).  If a non-empty
+# pattern is then received over the same control connection,
+# default behavior is restored.
+#
+# Each incoming query is converted into a string of the form
+# "qname qtype" (the printable query domain name, space,
+# printable query type) and matched against each pattern.
+#
+# The first pattern matching the query is selected, and
+# the RR following the pattern line are sent in the
+# answer section of the response.
+#
+# Each new control connection causes the current set of
+# patterns and responses to be cleared before adding new
+# ones.
+#
+# The server handles UDP and TCP queries.  Zone transfer
+# responses work, but must fit in a single 64 k message.
+#
+# Now you can add TSIG, just specify key/key data with:
+#
+#  /pattern <key> <key_data>/
+#  name ttl type rdata
+#  name ttl type rdata
+#
+#  Note that this data will still be sent with any request for
+#  pattern, only this data will be signed. Currently, this is only
+#  done for TCP.

+REQUIREMENTS
+ans.py requires at least dnspython 1.12.0.
+
+"ans.py" is a fairly simple Python script that will respond as an
+authoritative server to DNS queries. It opens a UDP socket on 10.53.0.4
+and fd92:7065:b8e:ffff::8, port 5300 (or PORT) (these are for DNS queries)
+and a TCP socket addresses on 10.53.0.4 at port 5301 (or EXTRAPORT1)
+(this is the control channel).
+
+Please note that all functionality and formatting are subject to change as
+we determine what features the tool will need.
+
+"ans.py" will respond to queries as follows: TBD

+# set up the RRs to be returned in the next answer
+#
+# the message contains up to two pipe-separated ('|') fields.
+#
+# the first field of the message is a comma-separated list
+# of actions indicating what to put into the answer set
+# (e.g., a dname, a cname, another cname, etc)
+#
+# supported actions:
+# - cname (cname from the current name to a new one in the same domain)
+# - dname (dname to a new domain, plus a synthesized cname)
+# - xname ("external" cname, to a new name in a new domain)
+#
+# example: xname, dname, cname represents a CNAME to an external
+# domain which is then answered by a DNAME and synthesized
+# CNAME pointing to yet another domain, which is then answered
+# by a CNAME within the same domain, and finally an answer
+# to the query. each RR in the answer set has a corresponding
+# RRSIG. these signatures are not valid, but will exercise the
+# response parser.
+#
+# the second field is a comma-separated list of which RRs in the
+# answer set to include in the answer, in which order. if prepended
+# with 's', the number indicates which signature to include.
+#
+# examples: for the answer set "cname, cname, cname", an rr set
+# '1, s1, 2, s2, 3, s3, 4, s4' indicates that all four RRs should
+# be included in the answer, with siagntures, in the origninal
+# order, while 4, s4, 3, s3, 2, s2, 1, s1' indicates the order
+# should be reversed, 's3, s3, s3, s3' indicates that the third
+# RRSIG should be repeated four times and everything else should
+# be omitted, and so on.

+# if there is no second field (i.e., no pipe symbol appears in

+To use the Dynamic DB sample driver, run named and check the log.
+
+    $ cd testing
+    $ named -gc named.conf
+
+You should be able to see something like:
+
+zone test/IN: loaded serial 0
+zone arpa/IN: loaded serial 0
+
+This means that the sample driver created empty zones "test." and
+"arpa." as defined by "arg" parameters in named.conf.
+
+$ dig @localhost test.
+
+should work as usual and you should be able to see the dummy zone with
+NS record pointing to the zone apex and A record with 127.0.0.1:
+
+;; ANSWER SECTION:
+test.			86400	IN	A	127.0.0.1
+test.			86400	IN	NS	test.
+test.			86400	IN	SOA	test. test. 0 28800 7200 604800 86400
+
+This driver creates two empty zones and allows query/transfer/update to
+all IP addresses for demonstration purposes.
+
+The driver wraps the RBT database implementation used natively by BIND,
+and modifies the addrdataset() and substractrdataset() functions to do
+additional work during dynamic updates.
+
+A dynamic update modifies the target zone as usual. After that, the
+driver detects whether the modified RR was of type A or AAAA, and if so,
+attempts to appropriately generate or delete a matching PTR record in
+one of the two zones managed by the driver.
+
+E.g.:
+
+$ nsupdate
+> update add a.test. 300 IN A 192.0.2.1
+> send
+
+will add the A record
+a.test.			300	IN	A	192.0.2.1
+
+and also automatically generate the PTR record
+1.2.0.192.in-addr.arpa.	300	IN	PTR	a.test.
+
+AXFR and RR deletion via dynamic updates should work as usual. Deletion
+of a type A or AAAA record should delete the corresponding PTR record
+too.
+
+The zone is stored only in memory, and all changes will be lost on
+reload/reconfig.
+
+Hints for code readers:
+- Driver initialization starts in driver.c: dyndb_init() function.
+- New database implementation is registered by calling dns_db_register()
+  and passing a function pointer to it. This sample uses the function
+  create_db() to initialize the database.
+- Zones are created later in instance.c: load_sample_instance_zones().
+- Database entry points are in structure db.c: dns_dbmethods_t
+  sampledb_methods
+- sampledb_methods points to an implementation of the database interface.
+  See the db.c: addrdataset() implementation and look at how the RBT
+  database instance is wrapped into an additional layer of logic.

+# This is a tool for sending an arbitrary packet via UDP or TCP to an
+# arbitrary address and port.  The packet is specified in a file or on
+# the standard input, in the form of a series of bytes in hexidecimal.
+# Whitespace is ignored, as is anything following a '#' symbol.
+#
+# For example, the following input would generate normal query for 
+# isc.org/NS/IN":
+#
+#     # QID:
+#     0c d8
+#     # header:
+#     01 00 00 01 00 00 00 00 00 00
+#     # qname isc.org:
+#     03 69 73 63 03 6f 72 67 00
+#     # qtype NS:
+#     00 02
+#     # qclass IN:
+#     00 01
+#
+# Note that we do not wait for a response for the server.  This is simply
+# a way of injecting arbitrary packets to test server resposnes.
+#
+# Usage: packet.pl [-a <address>] [-p <port>] [-t (udp|tcp)] [filename]

+#
+#               Should the input name be a punycode name, "dig +idnin" will also

+#
+# +[no]idnout - Translates the received punycode domain names into appropriate
+#               unicode characters before displaying.
+#
+# The tests run "dig" against an authoritative server configured with a minimal
+# root zone and nothing else.  As a result, all queries will result in an
+# NXDOMAIN.  The server will return the qname sent, which "dig" will display
+# according to the options selected.  This returned string is compared with
+# the qname originally sent.
+#
+# In the comments below, the following nomenclature (taken from RFC 5890) is
+# used:
+#
+# A-label: Label comprising ASCII characters that starts xn-- and whose
+#          characters after the xn-- are a valid output of the Punycode
+#          algorithm.
+#
+# Fake A-label: An A-label whose characters after the xn-- are not valid
+#          Punycode output.
+#
+# U-label: Unicode (native character) form of a label.
+#
+# For the purpose of this test script, U-labels do not include labels that
+# comprise purely ASCII characters, which are referred to as "ASCII-labels"
+# here. Valid ASCII-labels comprise letters, digits and hyphens and do not
+# start with a hyphen.

+This is for testing managed-keys, in particular with problems
+with RFC 5011 Automated Updates of DNSSEC Trust Anchors.
+
+ns1 is the root server that offers new KSKs and hosts one record for
+testing. The TTL for the zone's records is 2 seconds.
+
+ns2 is a validator that uses managed-keys.  "-T mkeytimers=2/20/40"
+is used so it will attempt do automated updates frequently. "-T tat=1"
+is used so it will send TAT queries once per second.
+
+ns3 is a validator with a broken key in managed-keys.
+
+ns5 is a validator which is prevented from getting a response from the
+root server, causing key refresh queries to fail.

+# Dynamic update test suite.
+#
+# Usage:
+#
+#   perl update_test.pl [-s server] [-p port] zone
+#
+# The server defaults to 127.0.0.1.
+# The port defaults to 53.
+#
+# The "Special NS rules" tests will only work correctly if the
+# zone has no NS records to begin with, or alternatively has a
+# single NS record pointing at the name "ns1" (relative to
+# the zone name).
+#
+# Installation notes:
+#
+# This program uses the Net::DNS::Resolver module.
+# You can install it by saying
+#
+#    perl -MCPAN -e "install Net::DNS"

+# This is a tool for sending an arbitrary packet via UDP or TCP to an

+# the standard input, in the form of a series of bytes in hexidecimal.
+# Whitespace is ignored, as is anything following a '#' symbol.
+#
+# For example, the following input would generate normal query for 
+# isc.org/NS/IN":
+#
+#     # QID:
+#     0c d8
+#     # header:
+#     01 00 00 01 00 00 00 00 00 00

+#     # qclass IN:
+#     00 01

+
+These tests check RPZ recursion behavior (including skipping
+recursion when appropriate).
+
+The general structure of the tests is:
+
+* The resolver (ns2) with an unqualified view containing the policy
+  zones, the response-policy statement, and a root hint zone
+
+* The auth server that contains two authoritative zones, l1.l0 and
+  l2.l1.l0, both delegated to itself. l2.l1.l0 specifies a non-existent
+  zone data file and so will generate SERVFAILs for any queries to it.
+
+The l2.l1.l0 zone was chosen to generate SERVFAIL responses because RPZ
+evaluation will use that error response whenever it encounters it during
+processing, thus making it a binary indicator for whether or not
+recursion was attempted.  This also allows us to not worry about having
+to craft 'ip', 'nsdname', and 'nsip' rules that matched the queries.
+
+Each test is intended to be fed a number of queries constructed as
+qXX.l2.l1.l0, where XX is the 1-based query sequence number (e.g. the
+first query of each test is q01.l2.l1.l0).
+
+For all the tests the triggers are constructed as follows:
+client-ip - match 127.0.0.1/32
+ip - match 255.255.255.255/32 (does not matter due to SERVFAIL)
+nsdname - match ns.example.org (also does not matter)
+nsip - match 255.255.255.255/32 (also does not matter)
+qname - match qXX.l2.l1.l0, where XX is the query sequence number that
+is intended to be matched by this qname rule.
+
+Here's the detail on the test cases:
+
+Group 1 - testing skipping recursion for a single policy zone with only
+records that allow recursion to be skipped
+
+Test 1a:
+    1 policy zone containing 1 'client-ip' trigger
+    1 query, expected to skip recursion
+
+Test 1b:
+    1 policy zone containing 1 'qname' trigger (q01)
+    2 queries, q01 is expected to skip recursion, q02 is expected to
+      recurse
+
+Test 1c:
+    1 policy zone containing both a 'client-ip' and 'qname' trigger (q02)
+    1 query, expected to skip recursion
+
+Group 2 - testing skipping recursion with multiple policy zones when all
+zones have only trigger types eligible to skip recursion with
+
+Test 2a:
+    32 policy zones, each containing 1 'qname' trigger (qNN, where NN is
+       the zone's sequence 1-based sequence number formatted to 2 digits,
+       so each of the first 32 queries should match a different zone)
+    33 queries, the first 32 of which are expected to skip recursion
+       while the 33rd is expected to recurse
+
+Group 3 - Testing interaction of triggers that require recursion when in
+a single zone, both alone and with triggers that allow recursion to be
+skipped
+
+Test 3a:
+    1 policy zone containing 1 'ip' trigger
+    1 query, expected to recurse
+
+Test 3b:
+    1 policy zone containing 1 'nsdname' trigger
+    1 query, expected to recurse
+
+Test 3c:
+    1 policy zone containing 1 'nsip' trigger
+    1 query, expected to recurse
+
+Test 3d:
+    1 policy zone containing 1 'ip' trigger and 1 'qname' trigger (q02)
+    2 queries, the first should not recurse and the second should recurse
+
+Test 3e:
+    1 policy zone containing 1 'nsdname' trigger and 1 'qname' trigger
+      (q02)
+    2 queries, the first should not recurse and the second should recurse
+
+Test 3f:
+    1 policy zone containing 1 'nsip' trigger and 1 'qname' trigger (q02)
+    2 queries, the first should not recurse and the second should recurse
+
+Group 4 - contains 32 subtests designed to verify that recursion is
+skippable for only the appropriate zones based on the order specified in
+the 'response-policy' statement
+
+Tests 4aa to 4bf:
+    32 policy zones per test, one of which is configured with 1 'ip'
+       trigger and one 'qname' trigger while the others are configured
+       only with 1 'qname' trigger.  The zone with both triggers starts
+       listed first and is moved backwards by one position with each
+       test.  The 'qname' triggers in the zones are structured so that
+       the zones are tested starting with the first zone and the 'ip'
+       trigger is tested before the 'qname' trigger for that zone.
+    33 queries per test, where the number expected to skip recursion
+       matches the test sequence number: e.g. 1 skip for 4aa, 26 skips
+       for 4az, and 32 skips for 4bf
+
+Group 5 - This test verifies that the "pivot" policy zone for whether or
+not recursion can be skipped is the first listed zone with applicable
+trigger types rather than a later listed zone.
+
+Test 5a:
+    5 policy zones, the 1st, 3rd, and 5th configured with 1 'qname'
+      trigger each (q01, q04, and q06, respectively), the 2nd and 4th
+      each configured with an 'ip' and 'qname' trigger (q02 and q05,
+      respectively for the 'qname' triggers
+    6 queries, of which only q01 and q02 are expected to skip recursion

+# Framework for starting test servers.
+# Based on the type of server specified, check for port availability, remove
+# temporary files, start the server, and verify that the server is running.
+# If a server is specified, start it. Otherwise, start all servers for test.
+
+use strict;
+use Cwd;
+use Cwd 'abs_path';
+use Getopt::Long;
+
+# Usage:
+#   perl start.pl [--noclean] [--restart] [--port port] test [server [options]]
+#
+#   --noclean       Do not cleanup files in server directory.
+#
+#   --restart       Indicate that the server is being restarted, so get the
+#                   server to append output to an existing log file instead of
+#                   starting a new one.
+#
+#   --port port     Specify the default port being used by the server to answer
+#                   queries (default 5300).  This script will interrogate the
+#                   server on this port to see if it is running. (Note: for
+#                   "named" nameservers, this can be overridden by the presence
+#                   of the file "named.port" in the server directory containing
+#                   the number of the query port.)
+#
+#   test            Name of the test directory.
+#
+#   server          Name of the server directory.  This will be of the form
+#                   "nsN" or "ansN", where "N" is an integer between 1 and 8.
+#                   If not given, the script will start all the servers in the
+#                   test directory.
+#
+#   options         Alternate options for the server.
+#
+#                   NOTE: options must be specified with '-- "<option list>"',
+#                   for instance: start.pl . ns1 -- "-c n.conf -d 43"

+#                   of the first non-commented/non-blank line of args in a file
+#                   called "named.args" in an ns*/ subdirectory. Only the FIRST

+# This is the name server from hell.  It provides canned
+# responses based on pattern matching the queries, and
+# can be reprogrammed on-the-fly over a TCP connection.
+#
+# The server listens for control connections on port 5301.
+# A control connection is a TCP stream of lines like
+#
+#  /pattern/
+#  name ttl type rdata
+#  name ttl type rdata
+#  ...
+#  /pattern/
+#  name ttl type rdata
+#  name ttl type rdata
+#  ...
+#
+# There can be any number of patterns, each associated
+# with any number of response RRs.  Each pattern is a
+# Perl regular expression.
+#
+# Each incoming query is converted into a string of the form
+# "qname qtype" (the printable query domain name, space,
+# printable query type) and matched against each pattern.
+#
+# The first pattern matching the query is selected, and
+# the RR following the pattern line are sent in the
+# answer section of the response.
+#
+# Each new control connection causes the current set of
+# patterns and responses to be cleared before adding new
+# ones.
+#
+# The server handles UDP and TCP queries.  Zone transfer
+# responses work, but must fit in a single 64 k message.
+#
+# Now you can add TSIG, just specify key/key data with:
+#
+#  /pattern <key> <key_data>/
+#  name ttl type rdata
+#  name ttl type rdata
+#
+#  Note that this data will still be sent with any request for
+#  pattern, only this data will be signed. Currently, this is only
+#  done for TCP.

+This is copied from ../system.
+
+This test suite uses a virtual time, gettimeofday(), select(),
+poll(), kevent() and epoll_wait() Unix system calls are redirected:
+gettimeofday() returns a date in virtual/exponentially inflated
+delay from an epoch, select(), poll(), kevent() and epoll_wait()
+timeouts are deflated down to at least 10ms.
+
+These tests depends on LD_PRELOAD being supported by the runtime
+loader.
+
+Beware BIND clock uses unsigned integer, in 22 seconds isc_time_now()
+overflows and breaks assertions. Note 22 real seconds is 136 virtual
+years...

+.SH "NAME"
+isc-hmac-fixup \- fixes HMAC keys generated by older versions of BIND
+.SH "SYNOPSIS"
+.HP \w'\fBisc\-hmac\-fixup\fR\ 'u
+\fBisc\-hmac\-fixup\fR {\fIalgorithm\fR} {\fIsecret\fR}
+.SH "DESCRIPTION"
+.PP
+Versions of BIND 9 up to and including BIND 9\&.6 had a bug causing HMAC\-SHA* TSIG keys which were longer than the digest length of the hash algorithm (i\&.e\&., SHA1 keys longer than 160 bits, SHA256 keys longer than 256 bits, etc) to be used incorrectly, generating a message authentication code that was incompatible with other DNS implementations\&.
+.PP
+This bug was fixed in BIND 9\&.7\&. However, the fix may cause incompatibility between older and newer versions of BIND, when using long keys\&.
+\fBisc\-hmac\-fixup\fR
+modifies those keys to restore compatibility\&.
+.PP
+To modify a key, run
+\fBisc\-hmac\-fixup\fR
+and specify the key\*(Aqs algorithm and secret on the command line\&. If the secret is longer than the digest length of the algorithm (64 bytes for SHA1 through SHA256, or 128 bytes for SHA384 and SHA512), then a new secret will be generated consisting of a hash digest of the old secret\&. (If the secret did not require conversion, then it will be printed without modification\&.)
+.SH "SECURITY CONSIDERATIONS"
+.PP
+Secrets that have been converted by
+\fBisc\-hmac\-fixup\fR
+are shortened, but as this is how the HMAC protocol works in operation anyway, it does not affect security\&. RFC 2104 notes, "Keys longer than [the digest length] are acceptable but the extra length would not significantly increase the function strength\&."

+\fBmdig\fR [@server] {global\-opt...} {{local\-opt...}\ {query}...}
+.SH "DESCRIPTION"
+.PP
+\fBmdig\fR
+is a multiple/pipelined query version of
+\fBdig\fR: instead of waiting for a response after sending each query, it begins by sending all queries\&. Responses are displayed in the order in which they are received, not in the order the corresponding queries were sent\&.
+.PP
+\fBmdig\fR
+options are a subset of the
+\fBdig\fR
+options, and are divided into "anywhere options" which can occur anywhere, "global options" which must occur before the query name (or they are ignored with a warning), and "local options" which apply to the next query on the command line\&.
+.PP
+The
+{@server}
+option is a mandatory global option\&. It is the name or IP address of the name server to query\&. (Unlike
+\fBdig\fR, this value is not retrieved from
+/etc/resolv\&.conf\&.) It can be an IPv4 address in dotted\-decimal notation, an IPv6 address in colon\-delimited notation, or a hostname\&. When the supplied
+\fIserver\fR
+argument is a hostname,
+\fBmdig\fR
+resolves that name before querying the name server\&.
+.PP
+\fBmdig\fR
+provides a number of query options which affect the way in which lookups are made and the results displayed\&. Some of these set or reset flag bits in the query header, some determine which sections of the answer get printed, and others determine the timeout and retry strategies\&.
+.PP
+Each query option is identified by a keyword preceded by a plus sign (+)\&. Some keywords set or reset an option\&. These may be preceded by the string
+no
+to negate the meaning of that keyword\&. Other keywords assign values to options like the timeout interval\&. They have the form
+\fB+keyword=value\fR\&.
+.SH "ANYWHERE OPTIONS"
+.PP
+The
+\fB\-f\fR
+option makes
+\fBmdig\fR
+operate in batch mode by reading a list of lookup requests to process from the file
+\fIfilename\fR\&. The file contains a number of queries, one per line\&. Each entry in the file should be organized in the same way they would be presented as queries to
+\fBmdig\fR
+using the command\-line interface\&.
+.PP
+The
+\fB\-h\fR
+causes
+\fBmdig\fR
+to print the detailed help with the full list of options and exit\&.
+.PP
+The
+\fB\-v\fR
+causes
+\fBmdig\fR
+to print the version number and exit\&.
+.SH "GLOBAL OPTIONS"
+.PP
+The
+\fB\-4\fR
+option forces
+\fBmdig\fR
+to only use IPv4 query transport\&.
+.PP
+The
+\fB\-6\fR
+option forces
+\fBmdig\fR
+to only use IPv6 query transport\&.
+.PP
+The
+\fB\-b\fR
+option sets the source IP address of the query to
+\fIaddress\fR\&. This must be a valid address on one of the host\*(Aqs network interfaces or "0\&.0\&.0\&.0" or "::"\&. An optional port may be specified by appending "#<port>"
+.PP
+The
+\fB\-m\fR
+option enables memory usage debugging\&.
+.PP
+The
+\fB\-p\fR
+option is used when a non\-standard port number is to be queried\&.
+\fIport#\fR
+is the port number that
+\fBmdig\fR
+will send its queries instead of the standard DNS port number 53\&. This option would be used to test a name server that has been configured to listen for queries on a non\-standard port number\&.
+.PP
+The global query options are:
+.PP
+\fB+[no]additional\fR

+.PP
+\fB+[no]crypto\fR
+.RS 4
+Toggle the display of cryptographic fields in DNSSEC records\&. The contents of these field are unnecessary to debug most DNSSEC validation failures and removing them makes it easier to see the common failures\&. The default is to display the fields\&. When omitted they are replaced by the string "[omitted]" or in the DNSKEY case the key id is displayed as the replacement, e\&.g\&. "[ key id = value ]"\&.
+.RE
+.PP
+\fB+dscp[=value]\fR

+.PP
+Reverse lookups \(em mapping addresses to names \(em are simplified by the
+\fB\-x\fR

+\fIaddr\fR
+is an IPv4 address in dotted\-decimal notation, or a colon\-delimited IPv6 address\&.
+\fBmdig\fR
+automatically performs a lookup for a query name like

+\fB+[no]adflag\fR
+.RS 4
+Set [do not set] the AD (authentic data) bit in the query\&. This requests the server to return whether all of the answer and authority sections have all been validated as secure according to the security policy of the server\&. AD=1 indicates that all records have been validated as secure and the answer is not from a OPT\-OUT range\&. AD=0 indicate that some part of the answer was insecure or not validated\&. This bit is set by default\&.

+
+    <para><command>mdig</command>
+      is a multiple/pipelined query version of <command>dig</command>:
+      instead of waiting for a response after sending each query,
+      it begins by sending all queries. Responses are displayed in
+      the order in which they are received, not in the order the
+      corresponding queries were sent.
+    </para>
+
+    <para>
+      <command>mdig</command> options are a subset of the
+      <command>dig</command> options, and are divided into "anywhere
+      options" which can occur anywhere, "global options" which must
+      occur before the query name (or they are ignored with a warning),
+      and "local options" which apply to the next query on the command
+      line.
+    </para>
+
+    <para>
+      The <arg choice="req" rep="norepeat">@server</arg> option is a mandatory global
+      option.  It is the name or IP address of the name server to query.
+      (Unlike <command>dig</command>, this value is not retrieved from
+      <filename>/etc/resolv.conf</filename>.)  It can be an IPv4 address
+      in dotted-decimal notation, an IPv6 address in colon-delimited
+      notation, or a hostname.  When the supplied
+      <parameter>server</parameter> argument is a hostname,
+      <command>mdig</command> resolves that name before querying
+      the name server.
+    </para>
+
+    <para><command>mdig</command>
+      provides a number of query options which affect
+      the way in which lookups are made and the results displayed.  Some of
+      these set or reset flag bits in the query header, some determine which
+      sections of the answer get printed, and others determine the timeout
+      and retry strategies.
+    </para>
+
+    <para>
+      Each query option is identified by a keyword preceded by a plus
+      sign (<literal>+</literal>).  Some keywords set or reset an
+      option.  These may be preceded by the string <literal>no</literal>
+      to negate the meaning of that keyword.  Other keywords assign
+      values to options like the timeout interval.  They have the
+      form <option>+keyword=value</option>.
+    </para>
+  </refsection>
+
+  <refsection><info><title>ANYWHERE OPTIONS</title></info>
+
+
+    <para>
+      The <option>-f</option> option makes <command>mdig</command>
+      operate in batch mode by reading a list of lookup requests to
+      process from the file <parameter>filename</parameter>.  The file
+      contains a number of queries, one per line.  Each entry in the
+      file should be organized in the same way they would be presented
+      as queries to <command>mdig</command> using the command-line interface.
+    </para>
+
+    <para>
+      The <option>-h</option> causes <command>mdig</command> to
+      print the detailed help with the full list of options and exit.
+    </para>
+
+    <para>
+      The <option>-v</option> causes <command>mdig</command> to
+      print the version number and exit.
+    </para>
+  </refsection>
+
+  <refsection><info><title>GLOBAL OPTIONS</title></info>
+
+
+    <para>
+      The <option>-4</option> option forces <command>mdig</command> to
+      only use IPv4 query transport.
+    </para>
+
+    <para>
+      The <option>-6</option> option forces <command>mdig</command> to
+      only use IPv6 query transport.
+    </para>
+
+    <para>
+      The <option>-b</option> option sets the source IP address of the
+      query to <parameter>address</parameter>.  This must be a valid
+      address on one of the host's network interfaces or "0.0.0.0" or
+      "::".  An optional port may be specified by appending
+      "#&lt;port&gt;"
+    </para>
+
+    <para>
+      The <option>-m</option> option enables memory usage debugging.
+    </para>
+
+    <para>
+      The <option>-p</option> option is used when a non-standard port
+      number is to be queried.
+      <parameter>port#</parameter> is the port number
+      that <command>mdig</command> will send its queries instead of
+      the standard DNS port number 53.  This option would be used to
+      test a name server that has been configured to listen for
+      queries on a non-standard port number.

+
+    <p><span class="command"><strong>mdig</strong></span>
+      is a multiple/pipelined query version of <span class="command"><strong>dig</strong></span>:
+      instead of waiting for a response after sending each query,
+      it begins by sending all queries. Responses are displayed in
+      the order in which they are received, not in the order the
+      corresponding queries were sent.
+    </p>
+
+    <p>
+      <span class="command"><strong>mdig</strong></span> options are a subset of the
+      <span class="command"><strong>dig</strong></span> options, and are divided into "anywhere
+      options" which can occur anywhere, "global options" which must
+      occur before the query name (or they are ignored with a warning),
+      and "local options" which apply to the next query on the command
+      line.
+    </p>
+
+    <p>
+      The {@server} option is a mandatory global
+      option.  It is the name or IP address of the name server to query.
+      (Unlike <span class="command"><strong>dig</strong></span>, this value is not retrieved from
+      <code class="filename">/etc/resolv.conf</code>.)  It can be an IPv4 address
+      in dotted-decimal notation, an IPv6 address in colon-delimited
+      notation, or a hostname.  When the supplied
+      <em class="parameter"><code>server</code></em> argument is a hostname,
+      <span class="command"><strong>mdig</strong></span> resolves that name before querying
+      the name server.
+    </p>
+
+    <p><span class="command"><strong>mdig</strong></span>
+      provides a number of query options which affect
+      the way in which lookups are made and the results displayed.  Some of
+      these set or reset flag bits in the query header, some determine which
+      sections of the answer get printed, and others determine the timeout
+      and retry strategies.
+    </p>
+
+    <p>
+      Each query option is identified by a keyword preceded by a plus
+      sign (<code class="literal">+</code>).  Some keywords set or reset an
+      option.  These may be preceded by the string <code class="literal">no</code>
+      to negate the meaning of that keyword.  Other keywords assign
+      values to options like the timeout interval.  They have the
+      form <code class="option">+keyword=value</code>.
+    </p>
+  </div>
+
+  <div class="refsection">
+<a name="id-1.8"></a><h2>ANYWHERE OPTIONS</h2>
+
+
+    <p>
+      The <code class="option">-f</code> option makes <span class="command"><strong>mdig</strong></span>
+      operate in batch mode by reading a list of lookup requests to
+      process from the file <em class="parameter"><code>filename</code></em>.  The file
+      contains a number of queries, one per line.  Each entry in the
+      file should be organized in the same way they would be presented
+      as queries to <span class="command"><strong>mdig</strong></span> using the command-line interface.
+    </p>
+
+    <p>
+      The <code class="option">-h</code> causes <span class="command"><strong>mdig</strong></span> to
+      print the detailed help with the full list of options and exit.
+    </p>
+
+    <p>
+      The <code class="option">-v</code> causes <span class="command"><strong>mdig</strong></span> to
+      print the version number and exit.
+    </p>

+\fBnamed\-journalprint\fR
+prints the contents of a zone journal file in a human\-readable form\&.
+.PP
+Journal files are automatically created by
+\fBnamed\fR
+when changes are made to dynamic zones (e\&.g\&., by
+\fBnsupdate\fR)\&. They record each addition or deletion of a resource record, in binary format, allowing the changes to be re\-applied to the zone when the server is restarted after a shutdown or crash\&. By default, the name of the journal file is formed by appending the extension
+\&.jnl
+to the name of the corresponding zone file\&.
+.PP
+\fBnamed\-journalprint\fR
+converts the contents of a given journal file into a human\-readable text format\&. Each line begins with "add" or "del", to indicate whether the record was added or deleted, and continues with the resource record in master\-file format\&.
