  35 <a name="id2543432"></a><h2>DESCRIPTION</h2>
  36 <p><span><strong class="command">rndc-confgen</strong></span>
  37       generates configuration files
  38       for <span><strong class="command">rndc</strong></span>.  It can be used as a
  39       convenient alternative to writing the
  40       <code class="filename">rndc.conf</code> file
  41       and the corresponding <span><strong class="command">controls</strong></span>
  42       and <span><strong class="command">key</strong></span>
  43       statements in <code class="filename">named.conf</code> by hand.
  44       Alternatively, it can be run with the <span><strong class="command">-a</strong></span>
  45       option to set up a <code class="filename">rndc.key</code> file and
  46       avoid the need for a <code class="filename">rndc.conf</code> file
  47       and a <span><strong class="command">controls</strong></span> statement altogether.
  48     </p>
  49 </div>
  50 <div class="refsect1" lang="en">
  51 <a name="id2543477"></a><h2>OPTIONS</h2>
  52 <div class="variablelist"><dl>
  53 <dt><span class="term">-a</span></dt>
  54 <dd>
  55 <p>
  56             Do automatic <span><strong class="command">rndc</strong></span> configuration.
  57             This creates a file <code class="filename">rndc.key</code>
  58             in <code class="filename">/etc</code> (or whatever
  59             <code class="varname">sysconfdir</code>
  60             was specified as when <acronym class="acronym">BIND</acronym> was
  61             built)
  62             that is read by both <span><strong class="command">rndc</strong></span>
  63             and <span><strong class="command">named</strong></span> on startup.  The
  64             <code class="filename">rndc.key</code> file defines a default
  65             command channel and authentication key allowing
  66             <span><strong class="command">rndc</strong></span> to communicate with
  67             <span><strong class="command">named</strong></span> on the local host
  68             with no further configuration.
  69           </p>
  70 <p>
  71             Running <span><strong class="command">rndc-confgen -a</strong></span> allows
  72             BIND 9 and <span><strong class="command">rndc</strong></span> to be used as
  73             drop-in
  74             replacements for BIND 8 and <span><strong class="command">ndc</strong></span>,
  75             with no changes to the existing BIND 8
  76             <code class="filename">named.conf</code> file.
  77           </p>
  78 <p>
  79             If a more elaborate configuration than that
  80             generated by <span><strong class="command">rndc-confgen -a</strong></span>
  81             is required, for example if rndc is to be used remotely,
  82             you should run <span><strong class="command">rndc-confgen</strong></span> without
  83             the
  84             <span><strong class="command">-a</strong></span> option and set up a
  85             <code class="filename">rndc.conf</code> and
  86             <code class="filename">named.conf</code>
  87             as directed.

  92             Specifies the size of the authentication key in bits.
  93             Must be between 1 and 512 bits; the default is 128.

 105 <dt><span class="term">-k <em class="replaceable"><code>keyname</code></em></span></dt>
 106 <dd><p>
 107             Specifies the key name of the rndc authentication key.
 108             This must be a valid domain name.
 109             The default is <code class="constant">rndc-key</code>.

 111 <dt><span class="term">-p <em class="replaceable"><code>port</code></em></span></dt>

 114             listens for connections from <span><strong class="command">rndc</strong></span>.
 115             The default is 953.

 117 <dt><span class="term">-r <em class="replaceable"><code>randomfile</code></em></span></dt>
 118 <dd><p>
 119             Specifies a source of random data for generating the
 120             authorization.  If the operating
 121             system does not provide a <code class="filename">/dev/random</code>
 122             or equivalent device, the default source of randomness
 123             is keyboard input.  <code class="filename">randomdev</code>
 124             specifies
 125             the name of a character device or file containing random
 126             data to be used instead of the default.  The special value
 127             <code class="filename">keyboard</code> indicates that keyboard
 128             input should be used.
 129           </p></dd>
 130 <dt><span class="term">-s <em class="replaceable"><code>address</code></em></span></dt>
 131 <dd><p>
 132             Specifies the IP address where <span><strong class="command">named</strong></span>
 133             listens for command channel connections from
 134             <span><strong class="command">rndc</strong></span>.  The default is the loopback

 139             Used with the <span><strong class="command">-a</strong></span> option to specify
 140             a directory where <span><strong class="command">named</strong></span> will run
 141             chrooted.  An additional copy of the <code class="filename">rndc.key</code>
 142             will be written relative to this directory so that
 143             it will be found by the chrooted <span><strong class="command">named</strong></span>.
 144           </p></dd>
 145 <dt><span class="term">-u <em class="replaceable"><code>user</code></em></span></dt>
