b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync verifies that the DNSSEC keys for a given zone or a set of zones

b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync have timing metadata set properly to ensure no future lapses in DNSSEC

b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync coverage.

b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync If <option>zone</option> is specified, then keys found in

b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync the key repository matching that zone are scanned, and an ordered

b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync list is generated of the events scheduled for that key (i.e.,

b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync publication, activation, inactivation, deletion). The list of

b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync events is walked in order of occurrence. Warnings are generated

b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync if any event is scheduled which could cause the zone to enter a

b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync state in which validation failures might occur: for example, if

b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync the number of published or active keys for a given algorithm drops

b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync to zero, or if a key is deleted from the zone too soon after a new

b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync key is rolled, and cached data signed by the prior key has not had

b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync time to expire from resolver caches.

b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync <para>

b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync Sets the directory in which keys can be found. Defaults to the

b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync current working directory.

<varlistentry>

<term>-f <replaceable class="parameter">file</replaceable></term>

<listitem>

<para>

If a <option>file</option> is specified, then the zone is

read from that file; the largest TTL and the DNSKEY TTL are

determined directly from the zone data, and the

<option>-m</option> and <option>-d</option> options do

not need to be specified on the command line.

</para>

</listitem>

</varlistentry>

<varlistentry>

<term>-l <replaceable class="parameter">duration</replaceable></term>

<listitem>

<para>

The length of time to check for DNSSEC coverage. Key events

scheduled further into the future than <option>duration</option>

will be ignored, and assumed to be correct.

</para>

<para>

The value of <option>duration</option> can be set in seconds,

or in larger units of time by adding a suffix: 'mi' for minutes,

'h' for hours, 'd' for days, 'w' for weeks, 'mo' for months,

'y' for years.

</para>

</listitem>

</varlistentry>

<varlistentry>

<term>-m <replaceable class="parameter">maximum TTL</replaceable></term>

<listitem>

<para>

Sets the value to be used as the maximum TTL for the zone or

zones being analyzed when determining whether there is a

possibility of validation failure. When a zone-signing key is

deactivated, there must be enough time for the record in the

zone with the longest TTL to have expired from resolver caches

before that key can be purged from the DNSKEY RRset. If that

condition does not apply, a warning will be generated.

</para>

<para>

The length of the TTL can be set in seconds, or in larger units

of time by adding a suffix: 'mi' for minutes, 'h' for hours,

'd' for days, 'w' for weeks, 'mo' for months, 'y' for years.

</para>

<para>

This option is mandatory unless the <option>-f</option> has

been used to specify a zone file. (If <option>-f</option> has

been specified, this option may still be used; it will overrde

the value found in the file.)

</para>

</listitem>

</varlistentry>

<varlistentry>

<term>-d <replaceable class="parameter">DNSKEY TTL</replaceable></term>

<listitem>

<para>

Sets the value to be used as the DNSKEY TTL for the zone or

zones being analyzed when determining whether there is a

possibility of validation failure. When a key is rolled (that

is, replaced with a new key), there must be enough time

for the old DNSKEY RRset to have expired from resolver caches

before the new key is activated and begins generating

signatures. If that condition does not apply, a warning

will be generated.

</para>

<para>

The length of the TTL can be set in seconds, or in larger units

of time by adding a suffix: 'mi' for minutes, 'h' for hours,

'd' for days, 'w' for weeks, 'mo' for months, 'y' for years.

</para>

<para>

This option is mandatory unless the <option>-f</option> has

been used to specify a zone file, or a default key TTL was

set with the <option>-L</option> to

<command>dnssec-keygen</command>. (If either of those is true,

this option may still be used; it will overrde the value found

in the zone or key file.)

</para>

</listitem>

</varlistentry>

<varlistentry>

<term>-r <replaceable class="parameter">resign interval</replaceable></term>

<listitem>

<para>

Sets the value to be used as the resign interval for the zone

or zones being analyzed when determining whether there is a

possibility of validation failure. This value defaults to

22.5 days, which is also the default in

<command>named</command>. However, if it has been changed

by the <option>sig-validity-interval</option> option in

<filename>named.conf</filename>, then it should also be

changed here.

</para>

<para>

The length of the interval can be set in seconds, or in larger

units of time by adding a suffix: 'mi' for minutes, 'h' for hours,

'd' for days, 'w' for weeks, 'mo' for months, 'y' for years.
