fb27aa740466280f820e13e238bc6dd0b477eb37vboxsync<p><code class="filename">rndc.conf</code> is much simpler than
9719c70242335a826a49f05c1a1f7c2cfd6a38cevboxsync <code class="filename">named.conf</code>. The file uses three
29e18dff973632afcdb1ebf98dbc9d38f80a7792vboxsync statements: an options statement, a server statement
29e18dff973632afcdb1ebf98dbc9d38f80a7792vboxsync and a key statement.
29e18dff973632afcdb1ebf98dbc9d38f80a7792vboxsync </p>
29e18dff973632afcdb1ebf98dbc9d38f80a7792vboxsync<p>
fb27aa740466280f820e13e238bc6dd0b477eb37vboxsync The <code class="option">options</code> statement contains five clauses.
The <code class="option">default-server</code> clause is followed by the
name or address of a name server. This host will be used when
no name server is given as an argument to
<span><strong class="command">rndc</strong></span>. The <code class="option">default-key</code>
clause is followed by the name of a key which is identified by
a <code class="option">key</code> statement. If no
<code class="option">keyid</code> is provided on the rndc command line,
and no <code class="option">key</code> clause is found in a matching
<code class="option">server</code> statement, this default key will be
used to authenticate the server's commands and responses. The
<code class="option">default-port</code> clause is followed by the port
to connect to on the remote name server. If no
<code class="option">port</code> option is provided on the rndc command
line, and no <code class="option">port</code> clause is found in a
matching <code class="option">server</code> statement, this default port
will be used to connect.
The <code class="option">default-source-address</code> and
<code class="option">default-source-address-v6</code> clauses which
can be used to set the IPv4 and IPv6 source addresses
respectively.
</p>
<p>
After the <code class="option">server</code> keyword, the server
statement includes a string which is the hostname or address
for a name server. The statement has three possible clauses:
<code class="option">key</code>, <code class="option">port</code> and
<code class="option">addresses</code>. The key name must match the
name of a key statement in the file. The port number
specifies the port to connect to. If an <code class="option">addresses</code>
clause is supplied these addresses will be used instead of
the server name. Each address can take a optional port.
If an <code class="option">source-address</code> or <code class="option">source-address-v6</code>
of supplied then these will be used to specify the IPv4 and IPv6
source addresses respectively.
</p>
<p>
The <code class="option">key</code> statement begins with an identifying
string, the name of the key. The statement has two clauses.
<code class="option">algorithm</code> identifies the encryption algorithm
for <span><strong class="command">rndc</strong></span> to use; currently only HMAC-MD5
is
supported. This is followed by a secret clause which contains
the base-64 encoding of the algorithm's encryption key. The
base-64 string is enclosed in double quotes.
</p>
<p>
There are two common ways to generate the base-64 string for the
secret. The BIND 9 program <span><strong class="command">rndc-confgen</strong></span>
can
be used to generate a random key, or the
<span><strong class="command">mmencode</strong></span> program, also known as
<span><strong class="command">mimencode</strong></span>, can be used to generate a
base-64
string from known input. <span><strong class="command">mmencode</strong></span> does
not
ship with BIND 9 but is available on many systems. See the
EXAMPLE section for sample command lines for each.
</p>

<pre class="programlisting">
options {
default-server localhost;
default-key samplekey;
};
</pre>
<p>
</p>
<pre class="programlisting">
server localhost {
key samplekey;
};
</pre>
<p>
</p>
<pre class="programlisting">
server testserver {
key testkey;
addresses { localhost port 5353; };
};
</pre>
<p>
</p>
<pre class="programlisting">
key samplekey {
algorithm hmac-md5;
secret "6FMfj43Osz4lyb24OIe2iGEz9lf1llJO+lz";
};
</pre>
<p>
</p>
<pre class="programlisting">
key testkey {
algorithm hmac-md5;
secret "R3HI8P6BKw9ZwXwN3VZKuQ==";
}
</pre>
<p>
</p>
<p>
In the above example, <span><strong class="command">rndc</strong></span> will by
default use
the server at localhost (127.0.0.1) and the key called samplekey.
Commands to the localhost server will use the samplekey key, which
must also be defined in the server's configuration file with the
same name and secret. The key statement indicates that samplekey
uses the HMAC-MD5 algorithm and its secret clause contains the
base-64 encoding of the HMAC-MD5 secret enclosed in double quotes.
</p>
<p>
If <span><strong class="command">rndc -s testserver</strong></span> is used then <span><strong class="command">rndc</strong></span> will
connect to server on localhost port 5353 using the key testkey.
</p>
<p>
To generate a random secret with <span><strong class="command">rndc-confgen</strong></span>:
</p>
<p><strong class="userinput"><code>rndc-confgen</code></strong>
</p>
<p>
A complete <code class="filename">rndc.conf</code> file, including
the
randomly generated key, will be written to the standard
output. Commented out <code class="option">key</code> and
<code class="option">controls</code> statements for
<code class="filename">named.conf</code> are also printed.
</p>
<p>
To generate a base-64 secret with <span><strong class="command">mmencode</strong></span>:
</p>
<p><strong class="userinput"><code>echo "known plaintext for a secret" | mmencode</code></strong>
</p>

<p>
The name server must be configured to accept rndc connections and
to recognize the key specified in the <code class="filename">rndc.conf</code>
file, using the controls statement in <code class="filename">named.conf</code>.
See the sections on the <code class="option">controls</code> statement in the
