Usage

kzonecheck [options] filename

Overview

The utility checks zone file syntax and runs semantic checks on the zone content. The executed checks are the same as the checks run by the Knot DNS server.

Please, refer to the semantic-checks configuration option in knot.conf(5) for the full list of available semantic checks.

Parameters

filename: Path to the zone file to be checked. For reading from stdin use /dev/stdin or just -.

Options

-o, --origin origin: Zone origin. If not specified, the SOA record owner in the zone file is used and the zone file name (without possible .zone suffix) is considered as the initial zone origin in case the owner isn't FQDN.

-d, --dnssec on|off: Also check DNSSEC-related records. The default is to decide based on the existence of a RRSIG for SOA.

-z, --zonemd: Also check the zone hash against a ZONEMD record, which is required to exist.

-t, --time time: Current time specification. Use UNIX timestamp, YYYYMMDDHHmmSS format, or [+/-]time[unit] format, where unit can be Y, M, D, h, m, or s. Default is current UNIX timestamp.

-j, --jobs jobs: The number of threads used for DNSSEC validation. Default is all CPU threads available.

-p, --print: Print the zone on stdout.

-v, --verbose: Enable debug output.

-h, --help: Print the program help.

-V, --version: Print the program version. The option -VV makes the program print the compile time configuration summary.

Exit status

Exit status of 0 means successful operation. Any other exit status indicates an error.
