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.
If ZONEMD resource records are present, one of them needs to match
the zone content.
- -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 (/usr/local/etc/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
- -Z
- Requires a valid ZONEMD RR to be present. When given once, this option
will permit verifying only the ZONEMD RR of an unsigned zone. When given
more than once, the zone needs to be validly DNSSEC signed as well.
- -ZZZ
- When three times a -Z option is given, the ZONEMD RR to be verified
is considered "detached" and does not need to have valid
signatures.
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.
- /usr/local/etc/unbound/root.key
- The file from which trusted keys are loaded for signature chasing, when no
-k option is given.
