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 \(dqhmac\-\(dq prefix may be omitted. +.TP +.B \fB\-h\fP +This option prints a short summary of options and arguments. +.TP +.B \fB\-k keyname\fP +This option specifies the key name of the DDNS authentication key. The +default is \fBddns\-key\fP when neither the \fB\-s\fP nor \fB\-z\fP option is +specified; otherwise, the default is \fBddns\-key\fP as a separate label +followed by the argument of the option, e.g., \fBddns\-key.example.com.\fP +The key name must have the format of a valid domain name, consisting of +letters, digits, hyphens, and periods. +.TP +.B \fB\-q\fP +This option enables quiet mode, which prints only the key, with no +explanatory text or usage examples. This is essentially identical to +\fBtsig\-keygen\fP\&. +.TP +.B \fB\-s name\fP +This option generates a configuration example to allow dynamic updates +of a single hostname. The example \fBnamed.conf\fP text shows how to set +an update policy for the specified name using the \(dqname\(dq nametype. The +default key name is \fBddns\-key.name\fP\&. Note that the \(dqself\(dq 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\fP option. +.TP +.B \fB\-z zone\fP +This option generates a configuration example to allow +dynamic updates of a zone. The example \fBnamed.conf\fP text shows how +to set an update policy for the specified zone using the \(dqzonesub\(dq +nametype, allowing updates to all subdomain names within that zone. +This option cannot be used with the \fB\-s\fP option. +.UNINDENT +.SH SEE ALSO +.sp +\fBnsupdate(1)\fP, \fBnamed.conf(5)\fP, \fBnamed(8)\fP, BIND 9 Administrator Reference Manual. +.SH AUTHOR +Internet Systems Consortium +.SH COPYRIGHT +2023, Internet Systems Consortium +.\" Generated by docutils manpage writer. +. |
