kzonecheck - Knot DNS zone check tool
kzonecheck [options] filename
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.
- filename
- Path to the zone file to be checked. For reading from stdin use
/dev/stdin or just -.
- -o, --origin
origin
- Zone origin. If not specified, the origin is determined from the file name
(possibly removing the .zone suffix).
- -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 of 0 means successful operation. Any other exit status
indicates an error.
