b8014c3bbb8a0f9d16e82278eabba771cbfd9b2evboxsync <para><command>rndc</command>

b8014c3bbb8a0f9d16e82278eabba771cbfd9b2evboxsync controls the operation of a name

b8014c3bbb8a0f9d16e82278eabba771cbfd9b2evboxsync server. It supersedes the <command>ndc</command> utility

b8014c3bbb8a0f9d16e82278eabba771cbfd9b2evboxsync that was provided in old BIND releases. If

b8014c3bbb8a0f9d16e82278eabba771cbfd9b2evboxsync <command>rndc</command> is invoked with no command line

b8014c3bbb8a0f9d16e82278eabba771cbfd9b2evboxsync options or arguments, it prints a short summary of the

b8014c3bbb8a0f9d16e82278eabba771cbfd9b2evboxsync supported commands and the available options and their

b8014c3bbb8a0f9d16e82278eabba771cbfd9b2evboxsync arguments.

b8014c3bbb8a0f9d16e82278eabba771cbfd9b2evboxsync communicates with the name server over a TCP connection, sending

b8014c3bbb8a0f9d16e82278eabba771cbfd9b2evboxsync commands authenticated with digital signatures. In the current

b8014c3bbb8a0f9d16e82278eabba771cbfd9b2evboxsync versions of

b8014c3bbb8a0f9d16e82278eabba771cbfd9b2evboxsync <command>rndc</command> and <command>named</command>,

b8014c3bbb8a0f9d16e82278eabba771cbfd9b2evboxsync the only supported authentication algorithms are HMAC-MD5

b8014c3bbb8a0f9d16e82278eabba771cbfd9b2evboxsync (for compatibility), HMAC-SHA1, HMAC-SHA224, HMAC-SHA256

b8014c3bbb8a0f9d16e82278eabba771cbfd9b2evboxsync (default), HMAC-SHA384 and HMAC-SHA512.

b8014c3bbb8a0f9d16e82278eabba771cbfd9b2evboxsync They use a shared secret on each end of the connection.

b8014c3bbb8a0f9d16e82278eabba771cbfd9b2evboxsync This provides TSIG-style authentication for the command

b8014c3bbb8a0f9d16e82278eabba771cbfd9b2evboxsync request and the name server's response. All commands sent

b8014c3bbb8a0f9d16e82278eabba771cbfd9b2evboxsync over the channel must be signed by a key_id known to the

b8014c3bbb8a0f9d16e82278eabba771cbfd9b2evboxsync server.

<listitem>

<para>

Sets a DNSSEC negative trust anchor (NTA)

for <option>domain</option>, with a lifetime of

<option>duration</option>. The default lifetime is

configured in <filename>named.conf</filename> via the

<option>nta-lifetime</option> option, and defaults to

one hour. The lifetime cannot exceed one week.

</para>

<para>

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), <command>named</command> will

abort the DNSSEC validation process and treat the data as

insecure rather than bogus. This continues until the

NTA's lifetime is elapsed.

</para>

<para>

NTAs persist across restarts of the <command>named</command> server.

The NTAs for a view are saved in a file called

<filename><replaceable>name</replaceable>.nta</filename>,

where <replaceable>name</replaceable> 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.

</para>

<para>

An existing NTA can be removed by using the

<option>-remove</option> option.

</para>

<para>

An NTA's lifetime can be specified with the

<option>-lifetime</option> 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 <option>lifetime</option> to zero

is equivalent to <option>-remove</option>.

</para>

<para>

If <option>-dump</option> 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).

</para>

<para>

Normally, <command>named</command> will periodically

test to see whether data below an NTA can now be

validated (see the <option>nta-recheck</option> 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 <option>-force</option> 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.

</para>

<para>

All of these options can be shortened, i.e., to

<option>-l</option>, <option>-r</option>, <option>-d</option>,

<listitem>

<para>

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

<command>sig-signing-type</command>.

<command>rndc signing -list</command> 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.

</para>

<para>

<command>rndc signing -clear</command> can remove

a single key (specified in the same format that

<command>rndc signing -list</command> 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.

</para>

<para>

<command>rndc signing -nsec3param</command> sets

the NSEC3 parameters for a zone. This is the

only supported mechanism for using NSEC3 with

<command>inline-signing</command> zones.

Parameters are specified in the same format as

an NSEC3PARAM resource record: hash algorithm,

flags, iterations, and salt, in that order.

</para>

<para>

Currently, the only defined value for hash algorithm

is <literal>1</literal>, representing SHA-1.

The <option>flags</option> may be set to

<literal>0</literal> or <literal>1</literal>,

depending on whether you wish to set the opt-out

bit in the NSEC3 chain. <option>iterations</option>

defines the number of additional times to apply

the algorithm when generating an NSEC3 hash. The

<option>salt</option> is a string of data expressed

in hexadecimal, a hyphen (`-') if no salt is

to be used, or the keyword <literal>auto</literal>,

which causes <command>named</command> to generate a

random 64-bit salt.

</para>

<para>

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:

<command>rndc signing -nsec3param 1 0 10 FFFF <replaceable>zone</replaceable></command>.

To set the opt-out flag, 15 iterations, and no

salt, use:

<command>rndc signing -nsec3param 1 1 15 - <replaceable>zone</replaceable></command>.

</para>

<para>

<command>rndc signing -nsec3param none</command>

removes an existing NSEC3 chain and replaces it

with NSEC.

</para>

<para>

<command>rndc signing -serial value</command> 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.
