  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.

  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>
