<a name="id2655454"></a><h2>DESCRIPTION</h2>
<p><span><strong class="command">rndc-confgen</strong></span>
      generates configuration files
      for <span><strong class="command">rndc</strong></span>.  It can be used as a
      convenient alternative to writing the
      <code class="filename">rndc.conf</code> file
      and the corresponding <span><strong class="command">controls</strong></span>
      and <span><strong class="command">key</strong></span>
      statements in <code class="filename">named.conf</code> by hand.
      Alternatively, it can be run with the <span><strong class="command">-a</strong></span>
      option to set up a <code class="filename">rndc.key</code> file and
      avoid the need for a <code class="filename">rndc.conf</code> file
      and a <span><strong class="command">controls</strong></span> statement altogether.
    </p>
</div>
<div class="refsect1" lang="en">
<a name="id2655521"></a><h2>OPTIONS</h2>
<div class="variablelist"><dl>
<dt><span class="term">-a</span></dt>
<dd>
<p>
            Do automatic <span><strong class="command">rndc</strong></span> configuration.
            This creates a file <code class="filename">rndc.key</code>
            in <code class="filename">/etc</code> (or whatever
            <code class="varname">sysconfdir</code>
            was specified as when <acronym class="acronym">BIND</acronym> was
            built)
            that is read by both <span><strong class="command">rndc</strong></span>
            and <span><strong class="command">named</strong></span> on startup.  The
            <code class="filename">rndc.key</code> file defines a default
            command channel and authentication key allowing
            <span><strong class="command">rndc</strong></span> to communicate with
            <span><strong class="command">named</strong></span> on the local host
            with no further configuration.
          </p>
<p>
            Running <span><strong class="command">rndc-confgen -a</strong></span> allows
            BIND 9 and <span><strong class="command">rndc</strong></span> to be used as
            drop-in
            replacements for BIND 8 and <span><strong class="command">ndc</strong></span>,
            with no changes to the existing BIND 8
            <code class="filename">named.conf</code> file.
          </p>
<p>
            If a more elaborate configuration than that
            generated by <span><strong class="command">rndc-confgen -a</strong></span>
            is required, for example if rndc is to be used remotely,
            you should run <span><strong class="command">rndc-confgen</strong></span> without
            the
            <span><strong class="command">-a</strong></span> option and set up a
            <code class="filename">rndc.conf</code> and
            <code class="filename">named.conf</code>
            as directed.
          </p>
</dd>
<dt><span class="term">-b <em class="replaceable"><code>keysize</code></em></span></dt>
<dd><p>
            Specifies the size of the authentication key in bits.
            Must be between 1 and 512 bits; the default is 128.
          </p></dd>
<dt><span class="term">-c <em class="replaceable"><code>keyfile</code></em></span></dt>
<dd><p>
            Used with the <span><strong class="command">-a</strong></span> option to specify
            an alternate location for <code class="filename">rndc.key</code>.
          </p></dd>
<dt><span class="term">-h</span></dt>
<dd><p>
            Prints a short summary of the options and arguments to
            <span><strong class="command">rndc-confgen</strong></span>.
          </p></dd>
<dt><span class="term">-k <em class="replaceable"><code>keyname</code></em></span></dt>
<dd><p>
            Specifies the key name of the rndc authentication key.
            This must be a valid domain name.
            The default is <code class="constant">rndc-key</code>.
          </p></dd>
<dt><span class="term">-p <em class="replaceable"><code>port</code></em></span></dt>
<dd><p>
            Specifies the command channel port where <span><strong class="command">named</strong></span>
            listens for connections from <span><strong class="command">rndc</strong></span>.
            The default is 953.
          </p></dd>
<dt><span class="term">-r <em class="replaceable"><code>randomfile</code></em></span></dt>
<dd><p>
            Specifies a source of random data for generating the
            authorization.  If the operating
            system does not provide a <code class="filename">/dev/random</code>
            or equivalent device, the default source of randomness
            is keyboard input.  <code class="filename">randomdev</code>
            specifies
            the name of a character device or file containing random
            data to be used instead of the default.  The special value
            <code class="filename">keyboard</code> indicates that keyboard
            input should be used.
          </p></dd>
<dt><span class="term">-s <em class="replaceable"><code>address</code></em></span></dt>
<dd><p>
            Specifies the IP address where <span><strong class="command">named</strong></span>
            listens for command channel connections from
            <span><strong class="command">rndc</strong></span>.  The default is the loopback
            address 127.0.0.1.
          </p></dd>
<dt><span class="term">-t <em class="replaceable"><code>chrootdir</code></em></span></dt>
<dd><p>
            Used with the <span><strong class="command">-a</strong></span> option to specify
            a directory where <span><strong class="command">named</strong></span> will run
            chrooted.  An additional copy of the <code class="filename">rndc.key</code>
            will be written relative to this directory so that
            it will be found by the chrooted <span><strong class="command">named</strong></span>.
          </p></dd>
<dt><span class="term">-u <em class="replaceable"><code>user</code></em></span></dt>
<dd><p>
            Used with the <span><strong class="command">-a</strong></span> option to set the
            owner
            of the <code class="filename">rndc.key</code> file generated.
            If
            <span><strong class="command">-t</strong></span> is also specified only the file
            in
            the chroot area has its owner changed.
