  54 <p><span><strong class="command">rndc-confgen</strong></span>
  55       generates configuration files
  56       for <span><strong class="command">rndc</strong></span>.  It can be used as a
  57       convenient alternative to writing the
  58       <code class="filename">rndc.conf</code> file
  59       and the corresponding <span><strong class="command">controls</strong></span>
  60       and <span><strong class="command">key</strong></span>
  61       statements in <code class="filename">named.conf</code> by hand.
  62       Alternatively, it can be run with the <span><strong class="command">-a</strong></span>
  63       option to set up a <code class="filename">rndc.key</code> file and
  64       avoid the need for a <code class="filename">rndc.conf</code> file
  65       and a <span><strong class="command">controls</strong></span> statement altogether.

  72 <dd>
  73 <p>
  74             Do automatic <span><strong class="command">rndc</strong></span> configuration.
  75             This creates a file <code class="filename">rndc.key</code>
  76             in <code class="filename">/etc</code> (or whatever
  77             <code class="varname">sysconfdir</code>
  78             was specified as when <acronym class="acronym">BIND</acronym> was
  79             built)
  80             that is read by both <span><strong class="command">rndc</strong></span>
  81             and <span><strong class="command">named</strong></span> on startup.  The
  82             <code class="filename">rndc.key</code> file defines a default
  83             command channel and authentication key allowing
  84             <span><strong class="command">rndc</strong></span> to communicate with
  85             <span><strong class="command">named</strong></span> on the local host
  86             with no further configuration.
  87           </p>
  88 <p>
  89             Running <span><strong class="command">rndc-confgen -a</strong></span> allows
  90             BIND 9 and <span><strong class="command">rndc</strong></span> to be used as
  91             drop-in
  92             replacements for BIND 8 and <span><strong class="command">ndc</strong></span>,
  93             with no changes to the existing BIND 8
  94             <code class="filename">named.conf</code> file.
  95           </p>
  96 <p>
  97             If a more elaborate configuration than that
  98             generated by <span><strong class="command">rndc-confgen -a</strong></span>
  99             is required, for example if rndc is to be used remotely,
 100             you should run <span><strong class="command">rndc-confgen</strong></span> without
 101             the
 102             <span><strong class="command">-a</strong></span> option and set up a
 103             <code class="filename">rndc.conf</code> and
 104             <code class="filename">named.conf</code>
 105             as directed.
