h2>DESCRIPTION</
h2>
1N/A<
p><
code class="filename">
rndc.conf</
code> is the configuration file
1N/A for <
span><
strong class="command">rndc</
strong></
span>, the BIND 9 name server control
1N/A utility. This file has a similar structure and syntax to
1N/A <
code class="filename">
named.conf</
code>. Statements are enclosed
1N/A in braces and terminated with a semi-colon. Clauses in
1N/A the statements are also semi-colon terminated. The usual
1N/A comment styles are supported:
1N/A C++ style: // to end of line
1N/A Unix style: # to end of line
1N/A<
p><
code class="filename">
rndc.conf</
code> is much simpler than
1N/A statements: an options statement, a server statement
1N/A and a key statement.
1N/A The <
code class="option">options</
code> statement contains five clauses.
1N/A The <
code class="option">default-server</
code> clause is followed by the
1N/A name or address of a name server. This host will be used when
1N/A no name server is given as an argument to
1N/A <
span><
strong class="command">rndc</
strong></
span>. The <
code class="option">default-key</
code>
1N/A clause is followed by the name of a key which is identified by
1N/A a <
code class="option">key</
code> statement. If no
1N/A <
code class="option">keyid</
code> is provided on the rndc command line,
1N/A and no <
code class="option">key</
code> clause is found in a matching
1N/A <
code class="option">server</
code> statement, this default key will be
1N/A used to authenticate the server's commands and responses. The
1N/A <
code class="option">default-port</
code> clause is followed by the port
1N/A to connect to on the remote name server. If no
1N/A <
code class="option">port</
code> option is provided on the rndc command
1N/A line, and no <
code class="option">port</
code> clause is found in a
1N/A matching <
code class="option">server</
code> statement, this default port
1N/A will be used to connect.
1N/A The <
code class="option">default-source-address</
code> and
1N/A <
code class="option">default-source-address-v6</
code> clauses which
1N/A can be used to set the IPv4 and IPv6 source addresses
1N/A After the <
code class="option">server</
code> keyword, the server
1N/A statement includes a string which is the hostname or address
1N/A for a name server. The statement has three possible clauses:
1N/A <
code class="option">key</
code>, <
code class="option">port</
code> and
1N/A <
code class="option">addresses</
code>. The key name must match the
1N/A name of a key statement in the file. The port number
1N/A specifies the port to connect to. If an <
code class="option">addresses</
code>
1N/A clause is supplied these addresses will be used instead of
1N/A the server name. Each address can take a optional port.
1N/A If an <
code class="option">source-address</
code> or <
code class="option">source-address-v6</
code>
1N/A of supplied then these will be used to specify the IPv4 and IPv6
1N/A source addresses respectively.
1N/A The <
code class="option">key</
code> statement begins with an identifying
1N/A string, the name of the key. The statement has two clauses.
1N/A <
code class="option">algorithm</
code> identifies the encryption algorithm
1N/A for <
span><
strong class="command">rndc</
strong></
span> to use; currently only HMAC-MD5
1N/A supported. This is followed by a secret clause which contains
1N/A the base-64 encoding of the algorithm's encryption key. The
1N/A base-64 string is enclosed in double quotes.
1N/A There are two common ways to generate the base-64 string for the
1N/A secret. The BIND 9 program <
span><
strong class="command">rndc-confgen</
strong></
span>
1N/A be used to generate a random key, or the
1N/A <
span><
strong class="command">mmencode</
strong></
span> program, also known as
1N/A <
span><
strong class="command">mimencode</
strong></
span>, can be used to generate a
1N/A string from known input. <
span><
strong class="command">mmencode</
strong></
span> does
1N/A ship with BIND 9 but is available on many systems. See the
1N/A EXAMPLE section for sample command lines for each.

1N/A Commands to the localhost server will use the samplekey key, which
1N/A must also be defined in the server's configuration file with the
1N/A same name and secret. The key statement indicates that samplekey
1N/A uses the HMAC-MD5 algorithm and its secret clause contains the
1N/A base-64 encoding of the HMAC-MD5 secret enclosed in double quotes.
