+lpd.conf \- configuration file for the LPRng line printer spooler system
+.fi
+.SH DESCRIPTION
+The file \fBlpd.conf\fR is used to provide configuration information for
+the LPRng Printer spooler system and defaults for printcap information.
+Leading spaces on lines are ignored,
+and blank lines and lines whose first nonblank character is a sharp
+(``#'') are ignored.
+Trailing blanks and tabs (whitespace) for an option value
+are deleted unless the last one is escaped with a backslash
+(``\\'').
+All other lines
+specify parameters and should be of the following form:
+.RS
+.nf
+keyword
+keyword@
+keyword#value
+keyword=value
+.RE
+.fi
+Note that these values are the same format as
+.BR printcap (5)
+values.
+Values in the configuration can contain
+host or machine dependent information;
+to assist with this,
+the following
+.I "escape sequences"
+in the configuration information are
+replaced as follows:
+.TP
+\fB%h\fR
+the short form
+of the host name
+(i.e.- non fully qualified).
+.TP
+\fB%H\fR
+the fully qualified host name.
+.TP
+\fB%a\fR
+the abbreviated architecture name,
+\fIsun4\fR, \fIsol2\fR, \fIhpux\fR, \fIaix\fR, \fIirix5\fR, etc.
+This value can be set using the \fBarchitecture\fR
+keyword in the configuration file and is set to a
+default value at compile_time.
+.TP
+\fB%P\fR
+the printer name from the printcap entry
+(see below).
+.TP
+\fB%R\fR
+the remote printer name from the printcap entry.
+.TP
+\fB%M\fR
+the remote host name from the printcap entry.
+This is truncated to the short host name.
+.PP
+For example,
+on host
+.I dickory.sdsu.edu,
+the strings
+.I "short=\fB%h\fR"
+.I "long=\fB%H\fR"
+.I "arch=\fB%a\fR"
+would be expanded as
+.I "short=dickory"
+.I "long=dickory.sdsu.edu"
+.I "arch=sun4" .
+.PP
+The P, R, and M tags are provided for use with combined
+configuration and printcap information.
+These values are not expanded when the printcap information is
+initially processed,
+and can be used only in a limited number of printcap or
+other entries.
+Currently only the
+printcap :sd: (spool directory)
+and :forward_server: (forward server) entries use these.
+.PP

+Name of the lock file.
+.TP
+\fBlocalhost\fR
+(default "localhost")
+The name of the localhost entry to be used for the TCP/IP
+loopback interface.
+The TCP/IP connection may originate from the local host;
+use this name to check to see if the local host address
+is in the IP address database,
+and use it as the origination address for local connections.
+This is done to avoid problems with multi-homed hosts
+who originate connections from different interfaces.
+.TP
+\fBlockfile\fR (default: /var/spool/lpd/lpd)
+The file used to indicate the presence of an \fBlpd\fR
+server running on the host. The lpd_port value is appended
+to the lockfile value to provide a unique lockfile
+even when different versions of LPRng are running
+on the same system.
+.TP
+\fBlogger_destination\fR
+(default: "")
+This specifies a destination for logger information generated by the lpd server.
+The formation of the destination specification is
+host[%port][,(TCP|UDP)].
+For example,
+localhost%2001,UDP would send logger information to the localhost IP address,
+on port 2001 using the UPD protocol.
+The default port and protocol are set by the
+default_logger_port and default_logger_protocol configuration variables respectively.
+.TP
+\fBlongnumber\fR
+(default: no)
+RFC1179 requires 3 digit job numbers;
+setting longnumber to yes allows 6 digit numbers.
+If the backwards_compatible flag is set,
+only 3 digit numbers will be used.
+.TP
+\fBlpd_listen_port\fR (default: =off) [ipaddr%]port
+The port that \fBlpd\fR binds to. If the parameter is set to off then
+\fBlpd\fR does not listen to any TCP port. See \fBlpd_port\fR for

+If this is not set at all, then \fBlpd\dP will listen on \fBlpd_port\fP.
+.TP
+\fBlpd_port\fR (default: \fIprinter\fR) [ipaddr%]port
+The port that \fBlpr\fR and
+the other client programs send their requests to.
+The specification has the format ipaddr%port.
+If the IP address is specified then a bind to only this address and
+port is done.
+If the port value is not a number
+a service lookup is performed and the corresponding
+service port is used; see services(5).
+This parameter is useful for debugging a new
+installation of LPRng, in that running LPRng on
+a different port from the default will not
+interfere with a previous installation of
+LPD or LPRng.
+.TP
+\fBlpd_printcap_path\fR (default: "")
+The location of
+.B lpd
+server only printcap database information.
+If this is nonblank the \fBprintcap_path\P will not be used by the
+.B lpd
+server.
+.TP
+\fBmail_operator_on_error\fR (default: "")
+Put this person on the CC-list of the mail, if it is not
+a success mail. (So in addition to the person who made the
+printer request, also this person gets error messages, but
+no success messages.)

+.TP
+\fBmax_status_size\fR (default: 10 (Kbytes))
+An integer value specifying (in K bytes)
+the maximum size of the status file
+to be generated during printing operations.
+A 0 value will create unlimited size status files.
+When the file size exceeds this value,
+it is truncated to
+.B min_status_size
+K bytes.
+.TP
+\fBmc\fR (default: 1)
+See \fBprintcap\fP(5) for details.
+.TP
+\fBmin_status_size\fR (default: 0 (Kbytes))

+.TP
+\fBminfree\fR (default: 0)
+The amount of free space (in Kbytes)
+needed in the spool directory in order
+for a job to be accepted.
+If 0, there is no limit;
+if the parameter is the name of a file rather than a number,
+the file must contain a numerical minimum free value (in Kbytes).
+This value is overridden by the printcap
+.I mi
+field value.
+.TP
+\fBms_time_resolution\fR
+(default: FALSE)
+This flag causes the time information to be printed to millisecond
+accuracy.
+This is overkill for most purposes.
+.TP
+\fBof_filter_options\fR
+(default: "")
+If this is not set,
+the value defaults to the same as the filter_options value.
+This string is appended to a OF filter specification,
+and the string expanded with values from the printcap information
+and job information.
+If the "bkf" (backwards compatible filter) flags is set in the
+printcap entry,
+of bk_of_filter_options value is appended instead

+.TP
+\fBoriginate_port\fR
+(default: "721 731")
+A range of port numbers to originate requests from.
+When sending service requests,
+the software will try to open and bind to these ports to
+originate a request to a server.
+If no port is given,
+or all of the requested ports are unavailable or cannot be
+bound to,
+then a normal use port is requested.
+Note that on UNIX systems,
+if a port in the range 0-1023 is requested the EUID of the
+process must be root for the request to be granted.
+Note that RFC1179 specifies that requests must
+originate from ports in the range 721-731.
+.TP
+\fBpass_env\fR
+(default: "LANG,LC_CTYPE,LC_NUMERIC,LC_TIME,LC_COLLATE,LC_MONETARY, LC_MESSAGES,LC_PAPER,LC_NAME,LC_ADDRESS,LC_TELEPHONE,LC_MEASUREMENT, LC_IDENTIFICATION,LC_ALL")
+Client programs such as LPR, LPC, etc., will pass these
+environment variables to any filter programs they start.
+.TP
+\fBpoll_time\fR (default: 6000)
+Interval in seconds at which LPD checks for queues with jobs and no
+server active.
+See

+If a file or filter does not exist, it is considered a fatal error.
+All valid entries in these files will be used.
+See PRINTCAP LOOKUP for details.
+.TP
+\fBperms_path\fR
+(default: /etc/lpd.perms:/usr/etc/lpd.perms: /var/spool/lpd/lpd.perms.%h)
+The location of the printer permissions database.

+Save a job in the spool queue after completion
+rather than removing it.
+.TP
+\fBsend_data_first\fR
+(default: no)
+Send data files of a job first,
+followed by the control file.
+.TP
+\fBsend_failure_action\fR (default: "")
+The lpd server uses this to determine the action to take when
+unable to print or process a job.
+The keyword
+\fIabort\fR
+will cause it to terminate operations,
+leaving the job in the queue,
+\fIremove\fR
+will cause it to remove the job,
+\fIretry\fR
+will cause it to retry the job,
+and
+\fIhold\fR
+will cause it to hold the job with an error indication.
+If the value is a filter,
+then the filter will be invoked and the exit status of the
+filter used to determine the actions.
+.TP
+\fBsend_job_rw_timeout\fR (default: 6000)
+When printing or sending a job to a remote printer,
+use this as a write to the device or remote host timeout value.
+If a timeout occurs,
+then a FAIL status is returned and
+the send_failure_action value is used to determine what to do on failure.
+.TP
+\fBsend_try\fR (default: 3)
+Numbers of times to try to send a job to the printer or remote host.
+A 0 value means an infinite number of times.
+.TP
+\fBsendmail\fR (default: "/usr/lib/sendmail -oi -t")

+jobs in different ways,
+depending on the name of the queue.
+.TP
+\fBuse_shorthost\fR (default: no)
+By default, names of lpr job files used the
+originating host fully qualified domain name.
+This can exceed 14 characters,
+the limit of file names on some UNIX systems.

+
+.SH "PRINTCAP LOOKUP, DATABASE FILES AND FILTERS"
+.PP
+The printcap_path
+and
+printer_perms_path
+variables specify a list of either data base files or filters to use to
+get printcap or permission entries for a printer.
+To get information,
+the filter is started and a single line with the printer name is
+sent to it.
+Note that the printer name
+.I all
+is used to request information either about all printers,
+or a specific printer entry that has a list of
+all printers.
+See
+.BR printcap (5)
+for more details.
+.PP
+To find the printcap information,
+LPRng programs will read the database files specified in the
+.I printcap_path
+entry.
+The
+.I lpd
+server will read any additional files specified in the
+.I lpd_printcap_path
+entry.
+If any of the files is missing or non-readable a fatal error will result.
+After having searched the various files,
+if a filter has been specified the filter will be started and
+the required printer name will be sent to the filter.
+The output from the filter will be used as the printcap information.
+.SH "SECURITY-RELATED PARAMETERS"
+.PP
+Environment variables are sanitized by \fBlpd\fR and the other
+executables, in that the variables \fIIFS\fR, \fILD_PRELOAD\fR
+and \fILD_PROFILE\fR are all deleted from the environment passed
+to filters and any other sub_processes.
+For more reliability,
+script filters should set their own
+PATH and LD_LIBRARY_PATH variables.
+.PP
+All filters will run as the user and group specified by the
+group and user variables.
