DESCRIPTION <\/a> <\/h2>\n

tsig\u2212keygen<\/b> and ddns\u2212confgen<\/b> 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 rndc<\/b> command channel.<\/p>\n

When run as tsig\u2212keygen<\/b>, 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 tsig\u2212key<\/b>.<\/p>\n

When run as ddns\u2212confgen<\/b>, the generated key is accompanied by configuration text and instructions that can be used with nsupdate<\/b> and named<\/b> when setting up dynamic DNS, including an example update\u2212policy<\/b> statement. (This usage similar to the rndc\u2212confgen<\/b> command for setting up command channel security.)<\/p>\n

Note that named<\/b> itself can configure a local DDNS key for use with nsupdate \u2212l<\/b>: it does this when a zone is configured with update\u2212policy local;<\/b>. ddns\u2212confgen<\/b> is only needed when a more elaborate configuration is required: for instance, if nsupdate<\/b> is to be used from a remote system.<\/p>\n

OPTIONS <\/a> <\/h2>\n

\u2212a algorithm<\/i><\/p>\n

Specifies the algorithm to use for the TSIG key. Available choices are: hmac\u2212md5, hmac\u2212sha1, hmac\u2212sha224, hmac\u2212sha256, hmac\u2212sha384 and hmac\u2212sha512. The default is hmac\u2212sha256. Options are case\u2212insensitive, and the “hmac\u2212” prefix may be omitted.<\/p>\n

\u2212h<\/p>\n

Prints a short summary of options and arguments.<\/p>\n

\u2212k keyname<\/i><\/p>\n

Specifies the key name of the DDNS authentication key. The default is ddns\u2212key<\/b> when neither the \u2212s<\/b> nor \u2212z<\/b> option is specified; otherwise, the default is ddns\u2212key<\/b> as a separate label followed by the argument of the option, e.g., ddns\u2212key.example.com.<\/b> The key name must have the format of a valid domain name, consisting of letters, digits, hyphens and periods.<\/p>\n

\u2212q<\/p>\n

(ddns\u2212confgen<\/b> only.) Quiet mode: Print only the key, with no explanatory text or usage examples; This is essentially identical to tsig\u2212keygen<\/b>.<\/p>\n

\u2212r randomfile<\/i><\/p>\n

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.<\/p>\n

\u2212s name<\/i><\/p>\n

(ddns\u2212confgen<\/b> only.) Generate configuration example to allow dynamic updates of a single hostname. The example named.conf<\/b> text shows how to set an update policy for the specified name<\/i> using the “name” nametype. The default key name is ddns\u2212key.name<\/i>. 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 \u2212z<\/b> option.<\/p>\n

\u2212z zone<\/i><\/p>\n

(ddns\u2212confgen<\/b> only.) Generate configuration example to allow dynamic updates of a zone: The example named.conf<\/b> text shows how to set an update policy for the specified zone<\/i> using the “zonesub” nametype, allowing updates to all subdomain names within that zone<\/i>. This option cannot be used with the \u2212s<\/b> option.<\/p>\n
