378N/A <title>DESCRIPTION</title>

183N/A <para><command>ddns-confgen</command>

183N/A generates a key for use by <command>nsupdate</command>

183N/A and <command>named</command>. It simplifies configuration

427N/A of dynamic zones by generating a key and providing the

427N/A <command>nsupdate</command> and <command>named.conf</command>

183N/A syntax that will be needed to use it, including an example

98N/A <command>update-policy</command> statement.

493N/A </para>

493N/A

493N/A <para>

98N/A If a domain name is specified on the command line, it will

493N/A be used in the name of the generated key and in the sample

493N/A <command>named.conf</command> syntax. For example,

493N/A <command>ddns-confgen example.com</command> would

98N/A generate a key called "ddns-key.example.com", and sample

156N/A <command>named.conf</command> command that could be used

156N/A in the zone definition for "example.com".

98N/A </para>

98N/A

493N/A <para>

493N/A Note that <command>named</command> itself can configure a

156N/A local DDNS key for use with <command>nsupdate -l</command>.

156N/A <command>ddns-confgen</command> is only needed when a

98N/A more elaborate configuration is required: for instance, if

98N/A <command>nsupdate</command> is to be used from a remote system.

98N/A choices are: hmac-md5, hmac-sha1, hmac-sha224, hmac-sha256,

98N/A hmac-sha384 and hmac-sha512. The default is hmac-sha256.

493N/A <para>

493N/A Specifies the key name of the DDNS authentication key.

493N/A The default is <constant>ddns-key</constant> when neither

493N/A the <option>-s</option> nor <option>-z</option> option is

98N/A specified; otherwise, the default

493N/A is <constant>ddns-key</constant> as a separate label

493N/A followed by the argument of the option, e.g.,

493N/A <constant>ddns-key.example.com.</constant>

493N/A The key name must have the format of a valid domain name,

493N/A consisting of letters, digits, hyphens and periods.

<term>-r <replaceable class="parameter">randomfile</replaceable></term>

<listitem>

<para>

Specifies a source of random data for generating the

authorization. If the operating system does not provide a

<filename>/dev/random</filename> or equivalent device, the

default source of randomness is keyboard input.

<filename>randomdev</filename> specifies the name of a

character device or file containing random data to be used

instead of the default. The special value

<filename>keyboard</filename> indicates that keyboard input

should be used.

<varlistentry>

<term>-s <replaceable class="parameter">name</replaceable></term>

<listitem>

<para>

Single host mode: The example <command>named.conf</command> text

shows how to set an update policy for the specified

<replaceable class="parameter">name</replaceable>

using the "name" nametype.

The default key name is

ddns-key.<replaceable class="parameter">name</replaceable>.

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 <option>-z</option> option.

</para>

</varlistentry>

<varlistentry>

<term>-z <replaceable class="parameter">zone</replaceable></term>

<listitem>

<para>

zone mode: The example <command>named.conf</command> text

shows how to set an update policy for the specified

<replaceable class="parameter">zone</replaceable>

using the "zonesub" nametype, allowing updates to all subdomain

names within

that <replaceable class="parameter">zone</replaceable>.

This option cannot be used with the <option>-s</option> option.
