c502126b6e8a5d0c5431f0314b4d6eb0d43ab53dStephan Bosch<p><span><strong class="command">rndc</strong></span>
c502126b6e8a5d0c5431f0314b4d6eb0d43ab53dStephan Bosch controls the operation of a name
c502126b6e8a5d0c5431f0314b4d6eb0d43ab53dStephan Bosch server. It supersedes the <span><strong class="command">ndc</strong></span> utility
c502126b6e8a5d0c5431f0314b4d6eb0d43ab53dStephan Bosch that was provided in old BIND releases. If
c502126b6e8a5d0c5431f0314b4d6eb0d43ab53dStephan Bosch <span><strong class="command">rndc</strong></span> is invoked with no command line
c502126b6e8a5d0c5431f0314b4d6eb0d43ab53dStephan Bosch options or arguments, it prints a short summary of the
c502126b6e8a5d0c5431f0314b4d6eb0d43ab53dStephan Bosch supported commands and the available options and their
c502126b6e8a5d0c5431f0314b4d6eb0d43ab53dStephan Bosch arguments.
c502126b6e8a5d0c5431f0314b4d6eb0d43ab53dStephan Bosch </p>
c502126b6e8a5d0c5431f0314b4d6eb0d43ab53dStephan Bosch<p><span><strong class="command">rndc</strong></span>
c502126b6e8a5d0c5431f0314b4d6eb0d43ab53dStephan Bosch communicates with the name server over a TCP connection, sending
c502126b6e8a5d0c5431f0314b4d6eb0d43ab53dStephan Bosch commands authenticated with digital signatures. In the current
c502126b6e8a5d0c5431f0314b4d6eb0d43ab53dStephan Bosch versions of
639bb36b12b9f9bb54c8bb1be50eac623622f8a0Timo Sirainen <span><strong class="command">rndc</strong></span> and <span><strong class="command">named</strong></span>,
639bb36b12b9f9bb54c8bb1be50eac623622f8a0Timo Sirainen the only supported authentication algorithms are HMAC-MD5
639bb36b12b9f9bb54c8bb1be50eac623622f8a0Timo Sirainen (for compatibility), HMAC-SHA1, HMAC-SHA224, HMAC-SHA256
c502126b6e8a5d0c5431f0314b4d6eb0d43ab53dStephan Bosch (default), HMAC-SHA384 and HMAC-SHA512.
c502126b6e8a5d0c5431f0314b4d6eb0d43ab53dStephan Bosch They use a shared secret on each end of the connection.
c502126b6e8a5d0c5431f0314b4d6eb0d43ab53dStephan Bosch This provides TSIG-style authentication for the command
c502126b6e8a5d0c5431f0314b4d6eb0d43ab53dStephan Bosch request and the name server's response. All commands sent
c502126b6e8a5d0c5431f0314b4d6eb0d43ab53dStephan Bosch over the channel must be signed by a key_id known to the
c502126b6e8a5d0c5431f0314b4d6eb0d43ab53dStephan Bosch server.

DNSSEC validation.
Note <span><strong class="command">dnssec-enable</strong></span> also needs to be
set to <strong class="userinput"><code>yes</code></strong> or
<strong class="userinput"><code>auto</code></strong> to be effective.
It defaults to enabled.

<dd>
<p>
Sets a DNSSEC negative trust anchor (NTA)
for <code class="option">domain</code>, with a lifetime of
<code class="option">duration</code>. The default lifetime is
configured in <code class="filename">named.conf</code> via the
<code class="option">nta-lifetime</code> option, and defaults to
one hour. The lifetime cannot exceed one week.
</p>
<p>
A negative trust anchor selectively disables
DNSSEC validation for zones that are known to be
failing because of misconfiguration rather than
an attack. When data to be validated is
at or below an active NTA (and above any other
configured trust anchors), <span><strong class="command">named</strong></span> will
abort the DNSSEC validation process and treat the data as
insecure rather than bogus. This continues until the
NTA's lifetime is elapsed.
</p>
<p>
NTAs persist across restarts of the named server.
The NTAs for a view are saved in a file called
<code class="filename"><em class="replaceable"><code>name</code></em>.nta</code>,
where <em class="replaceable"><code>name</code></em> is the
name of the view, or if it contains characters
that are incompatible with use as a file name, a
cryptographic hash generated from the name
of the view.
</p>
<p>
An existing NTA can be removed by using the
<code class="option">-remove</code> option.
</p>
<p>
An NTA's lifetime can be specified with the
<code class="option">-lifetime</code> option. TTL-style
suffixes can be used to specify the lifetime in
seconds, minutes, or hours. If the specified NTA
already exists, its lifetime will be updated to the
new value. Setting <code class="option">lifetime</code> to zero
is equivalent to <code class="option">-remove</code>.
</p>
<p>
If <code class="option">-dump</code> is used, any other arguments
are ignored, and a list of existing NTAs is printed
(note that this may include NTAs that are expired but
have not yet been cleaned up).
</p>
<p>
Normally, <span><strong class="command">named</strong></span> will periodically
test to see whether data below an NTA can now be
validated (see the <code class="option">nta-recheck</code> option
in the Administrator Reference Manual for details).
If data can be validated, then the NTA is regarded as
no longer necessary, and will be allowed to expire
early. The <code class="option">-force</code> overrides this
behavior and forces an NTA to persist for its entire
lifetime, regardless of whether data could be
validated if the NTA were not present.
</p>
<p>
All of these options can be shortened, i.e., to
<code class="option">-l</code>, <code class="option">-r</code>, <code class="option">-d</code>,
and <code class="option">-f</code>.

<dd>
<p>
Add a zone while the server is running. This
command requires the
<span><strong class="command">allow-new-zones</strong></span> option to be set
to <strong class="userinput"><code>yes</code></strong>. The
<em class="replaceable"><code>configuration</code></em> string
specified on the command line is the zone
configuration text that would ordinarily be
placed in <code class="filename">named.conf</code>.
</p>
<p>
The configuration is saved in a file called
<code class="filename"><em class="replaceable"><code>name</code></em>.nzf</code>,
where <em class="replaceable"><code>name</code></em> is the
name of the view, or if it contains characters
that are incompatible with use as a file name, a
cryptographic hash generated from the name
of the view.
When <span><strong class="command">named</strong></span> is
restarted, the file will be loaded into the view
configuration, so that zones that were added
can persist after a restart.
</p>
<p>
This sample <span><strong class="command">addzone</strong></span> command
would add the zone <code class="literal">example.com</code>
to the default view:
</p>
<p>
<code class="prompt">$ </code><strong class="userinput"><code>rndc addzone example.com '{ type master; file "example.com.db"; };'</code></strong>

configuration text.)

<dd>
<p>
Modify the configuration of a zone while the server
is running. This command requires the
<span><strong class="command">allow-new-zones</strong></span> option to be
set to <strong class="userinput"><code>yes</code></strong>. As with
<span><strong class="command">addzone</strong></span>, the
<em class="replaceable"><code>configuration</code></em> string
specified on the command line is the zone
configuration text that would ordinarily be
placed in <code class="filename">named.conf</code>.
</p>
<p>
If the zone was originally added via
<span><strong class="command">rndc addzone</strong></span>, the configuration
changes will be recorded permanently and will still be
in effect after the server is restarted or reconfigured.
However, if it was originally configured in
<code class="filename">named.conf</code>, then that original
configuration is still in place; when the server is
restarted or reconfigured, the zone will revert to
its original configuration. To make the changes
permanent, it must also be modified in
<code class="filename">named.conf</code>
</p>

<dd>
<p>
Delete a zone while the server is running.
</p>
<p>
If the <code class="option">-clean</code> is specified,
the zone's master file (and journal file, if any)
will be deleted along with the zone. Without the
<code class="option">-clean</code> option, zone files must
be cleaned up by hand. (If the zone is of
type "slave" or "stub", the files needing to
be cleaned up will be reported in the output
of the <span><strong class="command">rndc delzone</strong></span> command.)
</p>
<p>
If the zone was originally added via
<span><strong class="command">rndc addzone</strong></span>, then it will be
removed permanently. However, if it was originally
configured in <code class="filename">named.conf</code>, then
that original configuration is still in place; when
the server is restarted or reconfigured, the zone will
come back. To remove it permanently, it must also be
removed from <code class="filename">named.conf</code>

<dd>
<p>
List, edit, or remove the DNSSEC signing state records
for the specified zone. The status of ongoing DNSSEC
operations (such as signing or generating
NSEC3 chains) is stored in the zone in the form
of DNS resource records of type
<span><strong class="command">sig-signing-type</strong></span>.
<span><strong class="command">rndc signing -list</strong></span> converts
these records into a human-readable form,
indicating which keys are currently signing
or have finished signing the zone, and which NSEC3
chains are being created or removed.
</p>
<p>
<span><strong class="command">rndc signing -clear</strong></span> can remove
a single key (specified in the same format that
<span><strong class="command">rndc signing -list</strong></span> uses to
display it), or all keys. In either case, only
completed keys are removed; any record indicating
that a key has not yet finished signing the zone
will be retained.
</p>
<p>
<span><strong class="command">rndc signing -nsec3param</strong></span> sets
the NSEC3 parameters for a zone. This is the
only supported mechanism for using NSEC3 with
<span><strong class="command">inline-signing</strong></span> zones.
Parameters are specified in the same format as
an NSEC3PARAM resource record: hash algorithm,
flags, iterations, and salt, in that order.
</p>
<p>
Currently, the only defined value for hash algorithm
is <code class="literal">1</code>, representing SHA-1.
The <code class="option">flags</code> may be set to
<code class="literal">0</code> or <code class="literal">1</code>,
depending on whether you wish to set the opt-out
bit in the NSEC3 chain. <code class="option">iterations</code>
defines the number of additional times to apply
the algorithm when generating an NSEC3 hash. The
<code class="option">salt</code> is a string of data expressed
in hexadecimal, a hyphen (`-') if no salt is
to be used, or the keyword <code class="literal">auto</code>,
which causes <span><strong class="command">named</strong></span> to generate a
random 64-bit salt.
</p>
<p>
So, for example, to create an NSEC3 chain using
the SHA-1 hash algorithm, no opt-out flag,
10 iterations, and a salt value of "FFFF", use:
<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
salt, use:
<span><strong class="command">rndc signing -nsec3param 1 1 15 - <em class="replaceable"><code>zone</code></em></strong></span>.
</p>
<p>
<span><strong class="command">rndc signing -nsec3param none</strong></span>
removes an existing NSEC3 chain and replaces it
with NSEC.
</p>
<p>
<span><strong class="command">rndc signing -serial value</strong></span> sets
the serial number of the zone to value. If the value
would cause the serial number to go backwards it will
be rejected. The primary use is to set the serial on
inline signed zones.
