1N/A<
p><
span><
strong class="command">ddns-confgen</
strong></
span>
1N/A generates a key for use by <
span><
strong class="command">nsupdate</
strong></
span>
1N/A and <
span><
strong class="command">named</
strong></
span>. It simplifies configuration
1N/A of dynamic zones by generating a key and providing the
1N/A <
span><
strong class="command">nsupdate</
strong></
span> and <
span><
strong class="command">
named.conf</
strong></
span>
1N/A syntax that will be needed to use it, including an example
1N/A <
span><
strong class="command">update-policy</
strong></
span> statement.
1N/A If a domain name is specified on the command line, it will
1N/A be used in the name of the generated key and in the sample
1N/A <
span><
strong class="command">
named.conf</
strong></
span> syntax. For example,
1N/A <
span><
strong class="command">ddns-confgen
example.com</
strong></
span> would
1N/A <
span><
strong class="command">
named.conf</
strong></
span> command that could be used
1N/A Note that <
span><
strong class="command">named</
strong></
span> itself can configure a
1N/A local DDNS key for use with <
span><
strong class="command">nsupdate -l</
strong></
span>.
1N/A <
span><
strong class="command">ddns-confgen</
strong></
span> is only needed when a
1N/A more elaborate configuration is required: for instance, if
1N/A <
span><
strong class="command">nsupdate</
strong></
span> is to be used from a remote system.

1N/A Specifies the key name of the DDNS authentication key.
1N/A The default is <
code class="constant">ddns-key</
code> when neither
1N/A the <
code class="option">-s</

code class="option">-z</
code> option is
1N/A specified; otherwise, the default
1N/A is <

1N/A followed by the argument of the option,
e.g.,
1N/A The key name must have the format of a valid domain name,
1N/A consisting of letters, digits, hyphens and periods.

1N/A Specifies a source of random data for generating the
1N/A authorization. If the operating system does not provide a
1N/A <
code class="filename">/
dev/
random</
code> or equivalent device, the
1N/A default source of randomness is keyboard input.
1N/A <
code class="filename">randomdev</
code> specifies the name of a
1N/A character device or file containing random data to be used
1N/A instead of the default. The special value
1N/A <
