636c1d4a4a3c99faa799d834c46ef21923302da6vboxsync generates a key for use by <span><strong class="command">nsupdate</strong></span>
9d05cb8900409d466af41f602362f191bcd9e042vboxsync and <span><strong class="command">named</strong></span>. It simplifies configuration
9d05cb8900409d466af41f602362f191bcd9e042vboxsync of dynamic zones by generating a key and providing the
9d05cb8900409d466af41f602362f191bcd9e042vboxsync <span><strong class="command">nsupdate</strong></span> and <span><strong class="command">named.conf</strong></span>
636c1d4a4a3c99faa799d834c46ef21923302da6vboxsync syntax that will be needed to use it, including an example
636c1d4a4a3c99faa799d834c46ef21923302da6vboxsync <span><strong class="command">update-policy</strong></span> statement.
8b6d7e3d5672f9db05a27b3991948c7949f7bd57vboxsync If a domain name is specified on the command line, it will
1910146bc46e3eee5b8668806da594107fe9aabfvboxsync be used in the name of the generated key and in the sample
8b6d7e3d5672f9db05a27b3991948c7949f7bd57vboxsync <span><strong class="command">named.conf</strong></span> syntax. For example,
8b6d7e3d5672f9db05a27b3991948c7949f7bd57vboxsync <span><strong class="command">ddns-confgen example.com</strong></span> would
96248301537904df08dc56e1cf08d2f754457063vboxsync generate a key called "ddns-key.example.com", and sample
96248301537904df08dc56e1cf08d2f754457063vboxsync <span><strong class="command">named.conf</strong></span> command that could be used
96248301537904df08dc56e1cf08d2f754457063vboxsync in the zone definition for "example.com".
ecefceaf288db07aa576745c298dca85e162aea2vboxsync Note that <span><strong class="command">named</strong></span> itself can configure a
ecefceaf288db07aa576745c298dca85e162aea2vboxsync local DDNS key for use with <span><strong class="command">nsupdate -l</strong></span>.
af62929dce3cc5e14c75438cd2b893f82ae6dbc8vboxsync <span><strong class="command">ddns-confgen</strong></span> is only needed when a
af62929dce3cc5e14c75438cd2b893f82ae6dbc8vboxsync more elaborate configuration is required: for instance, if
2cd11b9eb48274eb1e6fd5a6d348f7c508d97851vboxsync <span><strong class="command">nsupdate</strong></span> is to be used from a remote system.

ecefceaf288db07aa576745c298dca85e162aea2vboxsync Specifies the algorithm to use for the TSIG key. Available
ecefceaf288db07aa576745c298dca85e162aea2vboxsync choices are: hmac-md5, hmac-sha1, hmac-sha224, hmac-sha256,
ecefceaf288db07aa576745c298dca85e162aea2vboxsync hmac-sha384 and hmac-sha512. The default is hmac-sha256.

ecefceaf288db07aa576745c298dca85e162aea2vboxsync Specifies the key name of the DDNS authentication key.
ecefceaf288db07aa576745c298dca85e162aea2vboxsync The default is <code class="constant">ddns-key</code> when neither
ecefceaf288db07aa576745c298dca85e162aea2vboxsync the <code class="option">-s</code> nor <code class="option">-z</code> option is
ecefceaf288db07aa576745c298dca85e162aea2vboxsync specified; otherwise, the default
ecefceaf288db07aa576745c298dca85e162aea2vboxsync is <code class="constant">ddns-key</code> as a separate label
ecefceaf288db07aa576745c298dca85e162aea2vboxsync followed by the argument of the option, e.g.,
636c1d4a4a3c99faa799d834c46ef21923302da6vboxsync <code class="constant">ddns-key.example.com.</code>
636c1d4a4a3c99faa799d834c46ef21923302da6vboxsync The key name must have the format of a valid domain name,
636c1d4a4a3c99faa799d834c46ef21923302da6vboxsync consisting of letters, digits, hyphens and periods.

8b6d7e3d5672f9db05a27b3991948c7949f7bd57vboxsync Specifies a source of random data for generating the
8b6d7e3d5672f9db05a27b3991948c7949f7bd57vboxsync authorization. If the operating system does not provide a
1910146bc46e3eee5b8668806da594107fe9aabfvboxsync <code class="filename">/dev/random</code> or equivalent device, the
8b6d7e3d5672f9db05a27b3991948c7949f7bd57vboxsync default source of randomness is keyboard input.
8b6d7e3d5672f9db05a27b3991948c7949f7bd57vboxsync <code class="filename">randomdev</code> specifies the name of a
96248301537904df08dc56e1cf08d2f754457063vboxsync character device or file containing random data to be used
1910146bc46e3eee5b8668806da594107fe9aabfvboxsync instead of the default. The special value
1910146bc46e3eee5b8668806da594107fe9aabfvboxsync <code class="filename">keyboard</code> indicates that keyboard input
d9d070cfd2c99624fe6974842b7ad4a30d5b71e7vboxsync should be used.
