KZONESIGN(1)

NAME
kzonesign - DNSSEC signing utility

SYNOPSIS

kzonesign [config_option] [options] zone_name

DESCRIPTION

This utility reads the zone's zone file, signs the zone according to given configuration, and writes the signed zone file back. An alternative mode is DNSSEC validation of the given zone. The signing or validation can run in parallel if enabled in the configuration (see policy.signing-threads and zone.adjust-threads).

  Parameters

zone_name
    A name of the zone to be signed.

  Config options

-c, --config file
    Use a textual configuration file (default is /usr/local/etc/knot/knot.conf).

-C, --confdb directory
    Use a binary configuration database directory (default is /usr/local/var/lib/knot/confdb). The default configuration database, if exists, has a preference to the default configuration file.

  Options

-o, --outdir dir_name
    Write the output zone file to the specified directory instead of the configured one.

-r, --rollover
    Allow key roll-overs and NSEC3 re-salt. In order to finish possible KSK submission, set the KSK's active timestamp to now (+0) using keymgr.

-v, --verify
    Instead of (re-)signing the zone, just verify that the zone is correctly signed.

-t, --time timestamp
    Sign/verify the zone (and roll the keys if necessary) as if it was at the time specified by timestamp.

-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 VALUES

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