Man1 - ldns-verify-zone.1

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

ldns-verify-zone ZONEFILE

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.

-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 (/etc/trusted-key.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

/period/s 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.

/etc/trusted-key.key

The file from which trusted keys are loaded for signature chasing, when no -k option is given.
