+ <title>DESCRIPTION</title>
+ <para><command>rndc</command>
+ controls the operation of a name
+ server. It supersedes the <command>ndc</command> utility
+ that was provided in old BIND releases. If
+ <command>rndc</command> is invoked with no command line
+ options or arguments, it prints a short summary of the
+ supported commands and the available options and their
+ arguments.
+ </para>
+ <para><command>rndc</command>
+ communicates with the name server
+ over a TCP connection, sending commands authenticated with
+ digital signatures. In the current versions of
+ <command>rndc</command> and <command>named</command>,
+ the only supported authentication algorithm is HMAC-MD5,
+ which uses a shared secret on each end of the connection.
+ This provides TSIG-style authentication for the command
+ request and the name server's response. All commands sent
+ over the channel must be signed by a key_id known to the
+ server.
+ </para>
+ <para><command>rndc</command>
+ reads a configuration file to
+ determine how to contact the name server and decide what
+ algorithm and key it should use.

+ Use <replaceable class="parameter">key-file</replaceable>
+ as the key file instead of the default,
+ <filename>/etc/rndc.key</filename>. The key in
+ <filename>/etc/rndc.key</filename> will be used to

+ does not exist.

+ </varlistentry>
+
+ <varlistentry>
+ <term>-s <replaceable class="parameter">server</replaceable></term>
+ <listitem>
+ <para><replaceable class="parameter">server</replaceable> is
+ the name or address of the server which matches a
+ server statement in the configuration file for
+ <command>rndc</command>. If no server is supplied on the
+ command line, the host named by the default-server clause
+ in the options statement of the <command>rndc</command>
+ configuration file will be used.

+ <term>-p <replaceable class="parameter">port</replaceable></term>
+ <listitem>
+ <para>

+ <term>-y <replaceable class="parameter">key_id</replaceable></term>
+ <listitem>
+ <para>
+ Use the key <replaceable class="parameter">key_id</replaceable>
+ from the configuration file.
+ <replaceable class="parameter">key_id</replaceable>
+ must be
+ known by named with the same algorithm and secret string
+ in order for control message validation to succeed.
+ If no <replaceable class="parameter">key_id</replaceable>
+ is specified, <command>rndc</command> will first look
+ for a key clause in the server statement of the server
+ being used, or if no server statement is present for that
+ host, then the default-key clause of the options statement.
+ Note that the configuration file contains shared secrets
+ which are used to send authenticated control commands
+ to name servers. It should therefore not have general read
+ or write access.
