0d43c6944bbca30d5692d4b02885f007a0c630c8Lennart Poettering<p><span><strong class="command">rndc</strong></span>
0d43c6944bbca30d5692d4b02885f007a0c630c8Lennart Poettering controls the operation of a name
0d43c6944bbca30d5692d4b02885f007a0c630c8Lennart Poettering server. It supersedes the <span><strong class="command">ndc</strong></span> utility
0d43c6944bbca30d5692d4b02885f007a0c630c8Lennart Poettering that was provided in old BIND releases. If
df50185b43916926a72246ab3a80875eda7ad2a3Lennart Poettering <span><strong class="command">rndc</strong></span> is invoked with no command line
e91af489a25e8bb65016a63f533ae28a505119efLennart Poettering options or arguments, it prints a short summary of the
55ee336cdcb57efe2ef9a4152f5b9e1063ec1a06Lennart Poettering supported commands and the available options and their
55ee336cdcb57efe2ef9a4152f5b9e1063ec1a06Lennart Poettering arguments.

0d43c6944bbca30d5692d4b02885f007a0c630c8Lennart Poettering communicates with the name server over a TCP connection, sending
0d43c6944bbca30d5692d4b02885f007a0c630c8Lennart Poettering commands authenticated with digital signatures. In the current
0d43c6944bbca30d5692d4b02885f007a0c630c8Lennart Poettering versions of
0d43c6944bbca30d5692d4b02885f007a0c630c8Lennart Poettering <span><strong class="command">rndc</strong></span> and <span><strong class="command">named</strong></span>,
0d43c6944bbca30d5692d4b02885f007a0c630c8Lennart Poettering the only supported authentication algorithms are HMAC-MD5
0d43c6944bbca30d5692d4b02885f007a0c630c8Lennart Poettering (for compatibility), HMAC-SHA1, HMAC-SHA224, HMAC-SHA256
0d43c6944bbca30d5692d4b02885f007a0c630c8Lennart Poettering (default), HMAC-SHA384 and HMAC-SHA512.
e91af489a25e8bb65016a63f533ae28a505119efLennart Poettering They use a shared secret on each end of the connection.
55ee336cdcb57efe2ef9a4152f5b9e1063ec1a06Lennart Poettering This provides TSIG-style authentication for the command
55ee336cdcb57efe2ef9a4152f5b9e1063ec1a06Lennart Poettering request and the name server's response. All commands sent
0d43c6944bbca30d5692d4b02885f007a0c630c8Lennart Poettering over the channel must be signed by a key_id known to the
0d43c6944bbca30d5692d4b02885f007a0c630c8Lennart Poettering server.

This command requires that the

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

configuration text that would ordinarily be

However, if it was originally configured in
<code class="filename">named.conf</code>, then that original

<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 <span><strong class="command">named</strong></span> 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>,

<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.
