  36 <p><span><strong class="command">rndc</strong></span>
  37       controls the operation of a name
  38       server.  It supersedes the <span><strong class="command">ndc</strong></span> utility
  39       that was provided in old BIND releases.  If
  40       <span><strong class="command">rndc</strong></span> is invoked with no command line
  41       options or arguments, it prints a short summary of the
  42       supported commands and the available options and their
  43       arguments.
  44     </p>
  45 <p><span><strong class="command">rndc</strong></span>
  46       communicates with the name server
  47       over a TCP connection, sending commands authenticated with
  48       digital signatures.  In the current versions of
  49       <span><strong class="command">rndc</strong></span> and <span><strong class="command">named</strong></span>,
  50       the only supported authentication algorithm is HMAC-MD5,
  51       which uses a shared secret on each end of the connection.
  52       This provides TSIG-style authentication for the command
  53       request and the name server's response.  All commands sent
  54       over the channel must be signed by a key_id known to the
  55       server.
  56     </p>
  57 <p><span><strong class="command">rndc</strong></span>
  58       reads a configuration file to
  59       determine how to contact the name server and decide what
  60       algorithm and key it should use.

  68             Use <em class="replaceable"><code>source-address</code></em>
  69             as the source address for the connection to the server.
  70             Multiple instances are permitted to allow setting of both

  77             <code class="filename">/etc/rndc.conf</code>.

  79 <dt><span class="term">-k <em class="replaceable"><code>key-file</code></em></span></dt>
  80 <dd><p>
  81             Use <em class="replaceable"><code>key-file</code></em>
  82             as the key file instead of the default,
  83             <code class="filename">/etc/rndc.key</code>.  The key in
  84             <code class="filename">/etc/rndc.key</code> will be used to
  85             authenticate
  86             commands sent to the server if the <em class="replaceable"><code>config-file</code></em>
  87             does not exist.
  88           </p></dd>
  89 <dt><span class="term">-s <em class="replaceable"><code>server</code></em></span></dt>
  90 <dd><p><em class="replaceable"><code>server</code></em> is
  91             the name or address of the server which matches a
  92             server statement in the configuration file for
  93             <span><strong class="command">rndc</strong></span>.  If no server is supplied on the
  94             command line, the host named by the default-server clause
  95             in the options statement of the <span><strong class="command">rndc</strong></span>
  96             configuration file will be used.

 102             instead
 103             of BIND 9's default control channel port, 953.

 109 <dt><span class="term">-y <em class="replaceable"><code>key_id</code></em></span></dt>
 110 <dd><p>
 111             Use the key <em class="replaceable"><code>key_id</code></em>
 112             from the configuration file.
 113             <em class="replaceable"><code>key_id</code></em>
 114             must be
 115             known by named with the same algorithm and secret string
 116             in order for control message validation to succeed.
 117             If no <em class="replaceable"><code>key_id</code></em>
 118             is specified, <span><strong class="command">rndc</strong></span> will first look
 119             for a key clause in the server statement of the server
 120             being used, or if no server statement is present for that
 121             host, then the default-key clause of the options statement.
 122             Note that the configuration file contains shared secrets
 123             which are used to send authenticated control commands
 124             to name servers.  It should therefore not have general read
 125             or write access.

 129       For the complete set of commands supported by <span><strong class="command">rndc</strong></span>,
 130       see the BIND 9 Administrator Reference Manual or run
 131       <span><strong class="command">rndc</strong></span> without arguments to see its help
 132       message.

 137 <p><span><strong class="command">rndc</strong></span>
 138       does not yet support all the commands of
 139       the BIND 8 <span><strong class="command">ndc</strong></span> utility.
 140     </p>
 141 <p>
 142       There is currently no way to provide the shared secret for a
 143       <code class="option">key_id</code> without using the configuration file.
 144     </p>
 145 <p>
 146       Several error messages could be clearer.
