DNSSEC-COVERAGE(8) | BIND 9 | DNSSEC-COVERAGE(8) |
NAME¶
dnssec-coverage - checks future DNSKEY coverage for a zone
SYNOPSIS¶
dnssec-coverage [-Kdirectory] [-llength] [-ffile] [-dDNSKEY TTL] [-mmax TTL] [-rinterval] [-ccompilezone path] [-k] [-z] [zone...]
DESCRIPTION¶
dnssec-coverage verifies that the DNSSEC keys for a given zone or a set of zones have timing metadata set properly to ensure no future lapses in DNSSEC coverage.
If zone is specified, then keys found in the key repository matching that zone are scanned, and an ordered list is generated of the events scheduled for that key (i.e., publication, activation, inactivation, deletion). The list of events is walked in order of occurrence. Warnings are generated if any event is scheduled which could cause the zone to enter a state in which validation failures might occur: for example, if the number of published or active keys for a given algorithm drops to zero, or if a key is deleted from the zone too soon after a new key is rolled, and cached data signed by the prior key has not had time to expire from resolver caches.
If zone is not specified, then all keys in the key repository will be scanned, and all zones for which there are keys will be analyzed. (Note: This method of reporting is only accurate if all the zones that have keys in a given repository share the same TTL parameters.)
OPTIONS¶
-K directory
-f file
-l duration
The value of duration 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.
-m maximum TTL
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.
This option is not necessary if the -f has been used to specify a zone file. If -f has been specified, this option may still be used; it will override the value found in the file.
If this option is not used and the maximum TTL cannot be retrieved from a zone file, a warning is generated and a default value of 1 week is used.
-d DNSKEY TTL
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.
This option is not necessary if -f has been used to specify a zone file from which the TTL of the DNSKEY RRset can be read, or if a default key TTL was set using ith the -L to dnssec-keygen. If either of those is true, this option may still be used; it will override the values found in the zone file or the key file.
If this option is not used and the key TTL cannot be retrieved from the zone file or the key file, then a warning is generated and a default value of 1 day is used.
-r resign interval
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.
