54 \fBddns\-confgen\fR, the generated key is accompanied by configuration text and instructions that can be used with
58 when setting up dynamic DNS, including an example
60 statement. (This usage similar to the
62 command for setting up command channel security.)
66 itself can configure a local DDNS key for use with
67 \fBnsupdate \-l\fR: it does this when a zone is configured with
68 \fBupdate\-policy local;\fR.
70 is only needed when a more elaborate configuration is required: for instance, if
72 is to be used from a remote system.
77 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.
82 Prints a short summary of options and arguments.
87 Specifies the key name of the DDNS authentication key. The default is
93 option is specified; otherwise, the default is
95 as a separate label followed by the argument of the option, e.g.,
96 \fBddns\-key.example.com.\fR
97 The key name must have the format of a valid domain name, consisting of letters, digits, hyphens and periods.

109 Specifies a source of random data for generating the authorization. If the operating system does not provide a
111 or equivalent device, the default source of randomness is keyboard input.
113 specifies the name of a character device or file containing random data to be used instead of the default. The special value
115 indicates that keyboard input should be used.
121 only.) Generate configuration example to allow dynamic updates of a single hostname. The example
123 text shows how to set an update policy for the specified
