970N/A<

970N/A controls the operation of a name
970N/A server. It supersedes the <
span><
strong class="command">ndc</
strong></
span> utility
970N/A that was provided in old BIND releases. If
970N/A <
span><
strong class="command">rndc</
strong></
span> is invoked with no command line
970N/A options or arguments, it prints a short summary of the
970N/A supported commands and the available options and their
970N/A<
p><
span><
strong class="command">rndc</
strong></
span>
970N/A communicates with the name server over a TCP connection, sending
970N/A commands authenticated with digital signatures. In the current
970N/A <
span><
strong class="command">rndc</
strong></
span> and <
span><
strong class="command">named</
strong></
span>,
970N/A the only supported authentication algorithms are HMAC-MD5
970N/A (for compatibility), HMAC-SHA1, HMAC-SHA224, HMAC-SHA256
1130N/A (default), HMAC-SHA384 and HMAC-SHA512.
970N/A They use a shared secret on each end of the connection.
970N/A This provides TSIG-style authentication for the command
970N/A request and the name server's response. All commands sent
970N/A over the channel must be signed by a key_id known to the
970N/A<
p><
span><
strong class="command">rndc</
strong></
span>
970N/A reads a configuration file to
970N/A determine how to contact the name server and decide what
970N/A algorithm and key it should use.

970N/A List, edit, or remove the DNSSEC signing state records
970N/A for the specified zone. The status of ongoing DNSSEC
970N/A operations (such as signing or generating
970N/A NSEC3 chains) is stored in the zone in the form
970N/A of DNS resource records of type
970N/A <
span><
strong class="command">sig-signing-type</
strong></
span>.
970N/A <
span><
strong class="command">rndc signing -list</
strong></
span> converts
970N/A these records into a human-readable form,
1423N/A indicating which keys are currently signing
1423N/A or have finished signing the zone, and which NSEC3
970N/A chains are being created or removed.
970N/A <
span><
strong class="command">rndc signing -clear</
strong></
span> can remove
970N/A a single key (specified in the same format that
970N/A <
span><
strong class="command">rndc signing -list</
strong></
span> uses to
970N/A display it), or all keys. In either case, only
970N/A completed keys are removed; any record indicating
970N/A that a key has not yet finished signing the zone
970N/A <
span><
strong class="command">rndc signing -nsec3param</
strong></
span> sets
970N/A the NSEC3 parameters for a zone. This is the
970N/A only supported mechanism for using NSEC3 with
1172N/A <
span><
strong class="command">inline-signing</
strong></
span> zones.
970N/A Parameters are specified in the same format as
970N/A an NSEC3PARAM resource record: hash algorithm,
970N/A flags, iterations, and salt, in that order.
970N/A Currently, the only defined value for hash algorithm
1207N/A is <
code class="literal">1</
code>, representing SHA-1.
1207N/A The <
code class="option">flags</
code> may be set to
1207N/A <
code class="literal">0</
code> or <
code class="literal">1</
code>,
1207N/A depending on whether you wish to set the opt-out
1207N/A bit in the NSEC3 chain. <
code class="option">iterations</
code>
1207N/A defines the number of additional times to apply
970N/A the algorithm when generating an NSEC3 hash. The
970N/A <
code class="option">salt</
code> is a string of data expressed
1447N/A in hexadecimal, a hyphen (`-') if no salt is
1447N/A to be used, or the keyword <
code class="literal">auto</
code>,
970N/A which causes <
span><
strong class="command">named</
strong></
span> to generate a
1463N/A So, for example, to create an NSEC3 chain using
1463N/A the SHA-1 hash algorithm, no opt-out flag,
1463N/A 10 iterations, and a salt value of "FFFF", use:
1463N/A <
span><
strong class="command">rndc signing -nsec3param 1 0 10 FFFF <
em class="replaceable"><
code>zone</
code></
em></
strong></
span>.
To set the opt-out flag, 15 iterations, and no
<
span><
strong class="command">rndc signing -nsec3param 1 1 15 - <
em class="replaceable"><
code>zone</
code></
em></
strong></
span>.
