Update content is read from a file (if the parameter \fIfilename\fP is given) or from the standard input. .sp The format of updates is textual and is made up of commands. Every command is placed on the separate line of the input. Lines starting with a semicolon are comments and are not processed. .SS Options .INDENT 0.0 .TP \fB\-d\fP Enable debug messages. .TP \fB\-h\fP, \fB\-\-help\fP Print the program help. .TP \fB\-k\fP \fIkeyfile\fP Use the TSIG key stored in a file \fIkeyfile\fP to authenticate the request. The file should contain the key in the same format, which is accepted by the \fB\-y\fP option. .TP \fB\-p\fP \fIport\fP Set the port to use for connections to the server (if not explicitly specified in the update). The default is 53. .TP \fB\-r\fP \fIretries\fP The number of retries for UDP requests. The default is 3. .TP \fB\-t\fP \fItimeout\fP The total timeout (for all UDP update tries) of the update request in seconds. The default is 12. If set to zero, the timeout is infinite. .TP \fB\-v\fP Use a TCP connection. .TP \fB\-V\fP, \fB\-\-version\fP Print the program version. .TP \fB\-y\fP [\fIalg\fP:]\fIname\fP:\fIkey\fP Use the TSIG key with a name \fIname\fP to authenticate the request. The \fIalg\fP part specifies the algorithm (the default is hmac\-sha256) and \fIkey\fP specifies the shared secret encoded in Base64. .UNINDENT .SS Commands .INDENT 0.0 .TP \fBserver\fP \fIname\fP [\fIport\fP] Specifies a receiving server of the dynamic update message. The \fIname\fP parameter can be either a host name or an IP address. If the \fIport\fP is not specified, the default port is used. The default port value can be controlled using the \fB\-p\fP program option. .TP \fBlocal\fP \fIaddress\fP [\fIport\fP] Specifies outgoing \fIaddress\fP and \fIport\fP\&. If no local is specified, the address and port are set by the system automatically. The default port number is 0. .TP \fBzone\fP \fIname\fP Specifies that all updates are done within a zone \fIname\fP\&. If not used, the default zone is the root zone. .TP \fBorigin\fP \fIname\fP Specifies fully qualified domain name suffix which is appended to non\-fqd owners in update commands. The default origin is the root zone. .TP \fBclass\fP \fIname\fP Sets \fIname\fP as the default class for all updates. If not used, the default class is IN. .TP \fBttl\fP \fIvalue\fP Sets \fIvalue\fP as the default TTL (in seconds). If not used, the default value is 0. .TP \fBkey\fP [\fIalg\fP:]\fIname\fP \fIkey\fP Specifies the TSIG \fIkey\fP named \fIname\fP to authenticate the request. An optional \fIalg\fP algorithm can be specified. This command has the same effect as the program option \fB\-y\fP\&. .TP [\fBprereq\fP] \fBnxdomain\fP \fIname\fP Adds a prerequisite for a non\-existing record owned by \fIname\fP\&. .TP [\fBprereq\fP] \fByxdomain\fP \fIname\fP Adds a prerequisite for an existing record owned by \fIname\fP\&. .TP [\fBprereq\fP] \fBnxrrset\fP \fIname\fP [\fIclass\fP] \fItype\fP Adds a prerequisite for a non\-existing record of the \fItype\fP owned by \fIname\fP\&. Internet \fIclass\fP is expected. .TP [\fBprereq\fP] \fByxrrset\fP \fIname\fP [\fIclass\fP] \fItype\fP [\fIdata\fP] Adds a prerequisite for an existing record of the \fItype\fP owned by \fIname\fP with optional \fIdata\fP\&. Internet \fIclass\fP is expected. .TP [\fBupdate\fP] \fBadd\fP \fIname\fP [\fIttl\fP] [\fIclass\fP] \fItype\fP \fIdata\fP Adds a request to add a new resource record into the zone. Please note that if the \fIname\fP is not fully qualified domain name, the current origin name is appended to it. .TP [\fBupdate\fP] \fBdel\fP[\fBete\fP] \fIname\fP [\fIttl\fP] [\fIclass\fP] [\fItype\fP] [\fIdata\fP] Adds a request to remove all (or matching \fIclass\fP, \fItype\fP or \fIdata\fP) resource records from the zone. There is the same requirement for the \fIname\fP parameter as in \fBupdate add\fP command. The \fIttl\fP item is ignored. .TP \fBshow\fP Displays current content of the update message. .TP \fBsend\fP Sends the current update message and cleans the list of updates. .TP \fBanswer\fP Displays the last answer from the server. .TP \fBdebug\fP Enable debugging. This command has the same meaning as the \fB\-d\fP program option. .TP \fBquit\fP Quit the program. .UNINDENT .SH NOTES .sp Options \fB\-k\fP and \fB\-y\fP can not be used simultaneously. .sp Dnssec\-keygen keyfile format is not supported. Use \fBkeymgr(8)\fP instead. .sp Zone name/server guessing is not supported if the zone name/server is not specified. .sp Empty line doesn\(aqt send the update. .SH EXAMPLES .INDENT 0.0 .IP 1. 3 Send one update of the zone example.com to the server 192.168.1.1.
