  70     <para><command>rndc-confgen</command>
  71       generates configuration files
  72       for <command>rndc</command>.  It can be used as a
  73       convenient alternative to writing the
  74       <filename>rndc.conf</filename> file
  75       and the corresponding <command>controls</command>
  76       and <command>key</command>
  77       statements in <filename>named.conf</filename> by hand.
  78       Alternatively, it can be run with the <command>-a</command>
  79       option to set up a <filename>rndc.key</filename> file and
  80       avoid the need for a <filename>rndc.conf</filename> file
  81       and a <command>controls</command> statement altogether.

  93           <para>
  94             Do automatic <command>rndc</command> configuration.
  95             This creates a file <filename>rndc.key</filename>
  96             in <filename>/etc</filename> (or whatever
  97             <varname>sysconfdir</varname>
  98             was specified as when <acronym>BIND</acronym> was
  99             built)
 100             that is read by both <command>rndc</command>
 101             and <command>named</command> on startup.  The
 102             <filename>rndc.key</filename> file defines a default
 103             command channel and authentication key allowing
 104             <command>rndc</command> to communicate with
 105             <command>named</command> on the local host
 106             with no further configuration.

 108           <para>
 109             Running <command>rndc-confgen -a</command> allows
 110             BIND 9 and <command>rndc</command> to be used as

 117             If a more elaborate configuration than that

 119             is required, for example if rndc is to be used remotely,
 120             you should run <command>rndc-confgen</command> without
 121             the
 122             <command>-a</command> option and set up a
 123             <filename>rndc.conf</filename> and
