ldns-verify-zone — read a DNSSEC signed zone and verify it.

Synopsis

ldns-verify-zone ZONEFILE

Description

ldns-verify-zone reads a DNS zone file and verifies it.

RRSIG resource records are checked against the DNSKEY set at the zone apex.

Each name is checked for an NSEC(3), if appropriate.

Options

-h
Show usage and exit
-a
Apex only, check only the zone apex
-e period
Signatures may not expire within this period. Default no period is used.
-i period
Signatures must have been valid at least this long. Default signatures should just be valid now.
-k file

A file that contains a trusted DNSKEY or DS rr. This option may be given more than once.

Alternatively, if -k is not specified, and a default trust anchor (/var/lib/unbound/root.key) exists and contains a valid DNSKEY or DS record, it will be used as the trust anchor.

-p [0-100]
Only check this percentage of the zone. Which names to check is determined randomly. Defaults to 100.
-S
Chase signature(s) to a known key. The network may be accessed to validate the zone's DNSKEYs. (implies -k)
-t YYYYMMDDhhmmss | [+|-]offset
Set the validation time either by an absolute time value or as an offset in seconds from the current time.
-v
Show the version and exit
-V number

Set the verbosity level (default 3):

0: Be silent
1: Print result, and any errors
2: Same as 1 for now
3: Print result, any errors, and the names that are
being checked
4: Same as 3 for now
5: Print the zone after it has been read, the result,
any errors, and the names that are being checked

periods are given in ISO 8601 duration format:

P[n]Y[n]M[n]DT[n]H[n]M[n]S

If no file is given standard input is read.

Files

/var/lib/unbound/root.key
The file from which trusted keys are loaded for signature chasing, when no -k option is given.
