       knotc - Knot DNS control utility


       knotc [parameters] action [action_args]


       If no action is specified, the program is executed in interactive mode.

       -c, –config file
              Use a textual configuration file (default is @config_dir@/knot.conf).

       -C, –confdb directory
              Use  a  binary  configuration database directory (default is @storage_dir@/confdb).
              The default configuration database, if exists, has  a  preference  to  the  default
              configuration file.

       -s, –socket path
              Use a control UNIX socket path (default is @run_dir@/knot.sock).

       -t, –timeout seconds
              Use a control timeout in seconds. Set 0 for infinity (default is 5).

       -f, –force
              Forced operation. Overrides some checks.

       -v, –verbose
              Enable debug output.

       -h, –help
              Print the program help.

       -V, –version
              Print the program version.

       status [detail]
              Check if the server is running. Details are version for the running server version,
              workers for the numbers of worker threads, or configure for the configure summary.

       stop   Stop the server if running.

       reload Reload the server configuration and modified zone files. All open zone transactions
              will be aborted!

       stats [module[.counter]]
              Show  global  statistics counter(s). To print also counters with value 0, use force

       zone-status zone [filter]
              Show the zone status.  Filters  are  +role,  +serial,  +transaction,  +events,  and

       zone-check [zone…]
              Test  if  the  server can load the zone. Semantic checks are executed if enabled in
              the configuration. (*)

       zone-memstats [zone…]
              Estimate memory use for the zone. (*)

       zone-reload [zone…]
              Trigger a zone reload from a disk without checking its modification time. For slave
              zone,  the  refresh  from  a  master  server  is  scheduled;  for  master zone, the
              notification of slave servers is  scheduled.  An  open  zone  transaction  will  be

       zone-refresh [zone…]
              Trigger a check for the zone serial on the zone’s master. If the master has a newer
              zone, a transfer is scheduled. This command is valid for slave zones.

       zone-retransfer [zone…]
              Trigger a zone transfer from the zone’s master. The server doesn’t check the serial
              of the master’s zone. This command is valid for slave zones.

       zone-notify [zone…]
              Trigger  a  NOTIFY  message  to all configured remotes. This can help in cases when
              previous NOTIFY had been lost or the slaves offline.

       zone-flush [zone…] [+outdir directory]
              Trigger a zone journal flush into the  zone  file.  If  output  dir  is  specified,
              instead  of  flushing  the  zonefile, the zone is dumped to a file in the specified

       zone-sign [zone…]
              Trigger a DNSSEC re-sign of the zone. Existing signatures will  be  dropped.   This
              command is valid for zones with automatic DNSSEC signing.

       zone-read zone [owner [type]]
              Get zone data that are currently being presented.

       zone-begin zone…
              Begin a zone transaction.

       zone-commit zone…
              Commit the zone transaction. All changes are applied to the zone.

       zone-abort zone…
              Abort the zone transaction. All changes are discarded.

       zone-diff zone
              Get zone changes within the transaction.

       zone-get zone [owner [type]]
              Get zone data within the transaction.

       zone-set zone owner [ttl] type rdata
              Add  zone record within the transaction. The first record in a rrset requires a ttl
              value specified.

       zone-unset zone owner [type [rdata]]
              Remove zone data within the transaction.

       zone-purge zone… [filter…]
              Purge zone data, file, journal, timers, and kaspdb.  Filters are +expire,  +timers,
              +zonefile, +journal, and +kaspdb.

       zone-stats zone [module[.counter]]
              Show  zone  statistics  counter(s).  To print also counters with value 0, use force

       zone-freeze [zone…]
              Temporarily postpone zone-changing events (load, refresh, update, flush, and DNSSEC

       zone-thaw [zone…]
              Dismiss zone freeze.

       zone-ksk-submitted zone
              Use  when  the  zone’s KSK rollover is in submittion phase. By calling this command
              the user confirms manually that the parent zone contains DS record for the new  KSK
              in submission phase and the old KSK can be retired.

              Initialize the configuration database. (*)

              Check the server configuration. (*)

       conf-import filename
              Import  a  configuration file into the configuration database. Ensure the server is
              not using the configuration database! (*)

       conf-export [filename]
              Export the configuration database into a config file or stdout. (*)

       conf-list [item]
              List the configuration database sections or section items.

       conf-read [item]
              Read the item from the active configuration database.

              Begin a writing configuration database transaction. Only  one  transaction  can  be
              opened at a time.

              Commit the configuration database transaction.

              Rollback the configuration database transaction.

       conf-diff [item]
              Get the item difference in the transaction.

       conf-get [item]
              Get the item data from the transaction.

       conf-set item [data…]
              Set the item data in the transaction.

       conf-unset [item] [data…]
              Unset the item data in the transaction.

       Empty or  zone parameter means all zones or all zones with a transaction.

       Use @ owner to denote the zone name.

       Type item parameter in the form of section[[id]][.name].

       (*) indicates a local operation which requires a configuration.

   Interactive mode
       The  utility  provides  interactive  mode  with  basic line editing functionality, command
       completion, and command history.

       Interactive mode behavior can be customized in ~/.editrc. Refer to editrc(5) for details.

       Command history is saved in ~/.knotc_history.
