DDNS-CONFGEN(8)                                     BIND9                                    DDNS-CONFGEN(8)



NAME
       ddns-confgen - ddns key generation tool

SYNOPSIS
       ddns-confgen [-a algorithm] [-h] [-k keyname] [-r randomfile] [-s name | -z zone] [-q] [name]

DESCRIPTION
       ddns-confgen generates a key for use by nsupdate and named. It simplifies configuration of dynamic
       zones by generating a key and providing the nsupdate and named.conf syntax that will be needed to use
       it, including an example update-policy statement.

       If a domain name is specified on the command line, it will be used in the name of the generated key
       and in the sample named.conf syntax. For example, ddns-confgen example.com would generate a key
       called "ddns-key.example.com", and sample named.conf command that could be used in the zone
       definition for "example.com".

       Note that named itself can configure a local DDNS key for use with nsupdate -l.  ddns-confgen is only
       needed when a more elaborate configuration is required: for instance, if nsupdate is to be used from
       a remote system.

OPTIONS
       -a algorithm
           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.

       -h
           Prints a short summary of the options and arguments to ddns-confgen.

       -k keyname
           Specifies the key name of the DDNS authentication key. The default is ddns-key when neither the
           -s nor -z option is specified; otherwise, the default is ddns-key as a separate label followed by
           the argument of the option, e.g., ddns-key.example.com.  The key name must have the format of a
           valid domain name, consisting of letters, digits, hyphens and periods.

       -q
           Quiet mode: Print only the key, with no explanatory text or usage examples.

       -r randomfile
           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.

       -s name
           Single host mode: The example named.conf text shows how to set an update policy for the specified
           name using the "name" nametype. The default key name is ddns-key.name. 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 -z option.

       -z zone
           zone mode: The example named.conf text shows how to set an update policy for the specified zone
           using the "zonesub" nametype, allowing updates to all subdomain names within that zone. This
           option cannot be used with the -s option.
