Set to 0 for infinity (default is 60). +The control socket operations are also subject to the \fI\%timeout\fP +parameter set on the server side in server\(aqs Control configuration section. +.TP +\fB\-b\fP, \fB\-\-blocking\fP +Zone event trigger commands wait until the event is finished. Control timeout +is set to infinity if not forced by explicit timeout specification. +.TP +\fB\-e\fP, \fB\-\-extended\fP +Show extended output (even empty items in zone status). +.TP +\fB\-f\fP, \fB\-\-force\fP +Forced operation. Overrides some checks. +.TP +\fB\-x\fP, \fB\-\-mono\fP +Don\(aqt generate colorized output. +.TP +\fB\-X\fP, \fB\-\-color\fP +Force colorized output in extended output or to a pipe. +.TP +\fB\-v\fP, \fB\-\-verbose\fP +Enable debug output. +.TP +\fB\-h\fP, \fB\-\-help\fP +Print the program help. +.TP +\fB\-V\fP, \fB\-\-version\fP +Print the program version. +.UNINDENT +.SS Actions +.INDENT 0.0 +.TP +\fBstatus\fP [\fIdetail\fP] +Check if the server is running. Details are \fBversion\fP for the running +server version, \fBworkers\fP for the numbers of worker threads, +\fBconfigure\fP for the configure summary, or \fBcert\-key\fP for the +public key pin of the currently used certificate. +.TP +\fBstop\fP +Stop the server if running. +.TP +\fBreload\fP +Reload the server configuration and modified zone files. All open zone +transactions will be aborted! +.TP +\fBstats\fP [\fImodule\fP[\fB\&.\fP\fIcounter\fP]] +Show global statistics counter(s). To print also counters with value 0, use +force option. +.TP +\fBzone\-check\fP [\fIzone\fP\&...] +Test if the server can load the zone. Semantic checks are executed if enabled +in the configuration. If invoked with the force option, an error is returned +when semantic check warning appears. (*) +.TP +\fBzone\-status\fP [\fIzone\fP\&...] [\fIfilter\fP] +Show the zone status. Filters are \fB+role\fP, \fB+serial\fP, \fB+transaction\fP, +\fB+events\fP, \fB+freeze\fP, and \fB+catalog\fP\&. Empty zone parameters are omitted, +unless the \fB\-\-extended\fP option is used. A single dash in the output represents +an unset value. Automatic colorization can be overruled using the \fB\-\-mono\fP and +\fB\-\-color\fP options. +.sp +The color code is: +\fIgreen\fP \- zone acts as a master / \fIred\fP \- zone acts as a slave, +\fIbold font (highlited)\fP \- zone is active / \fInormal\fP \- zone is empty, +\fIunderscored\fP \- zone is an interpreted catalog member. +.TP +\fBzone\-reload\fP [\fIzone\fP\&...] +Trigger a zone reload from a disk without checking its modification time. For +secondary zone, the refresh event from primary server(s) is scheduled; +for primary zone, the notify event to secondary server(s) is scheduled. An open +zone transaction will be aborted! If invoked with the force option, also zone +modules will be re\-loaded, but blocking mode might not work reliably. (#) +.TP +\fBzone\-refresh\fP [\fIzone\fP\&...] +Trigger a check for the zone serial on the zone\(aqs primary server. If +the primary server has a newer zone, a transfer is scheduled. This command is +valid for secondary zones. (#) +.TP +\fBzone\-retransfer\fP [\fIzone\fP\&...] +Trigger a zone transfer from the zone\(aqs primary server. The server +doesn\(aqt check the serial of the primary server\(aqs zone. This command is valid +for secondary zones. (#) +.TP +\fBzone\-notify\fP [\fIzone\fP\&...] +Trigger a NOTIFY message to all configured remotes. This can help in cases +when previous NOTIFY had been lost or the secondary servers have been +offline. (#) +.TP +\fBzone\-flush\fP [\fIzone\fP\&...] [\fB+outdir\fP \fIdirectory\fP] +Trigger a zone journal flush to the configured zone file. If an output +directory is specified, the current zone is immediately dumped (in the +blocking mode) to a zone file in the specified directory. See +\fI\%Notes\fP below about the directory permissions. (#) +.TP +\fBzone\-backup\fP [\fIzone\fP\&...] \fB+backupdir\fP \fIdirectory\fP [\fIfilter\fP\&...] +Trigger a zone data and metadata backup to a specified directory. +Available filters are \fB+zonefile\fP, \fB+journal\fP, \fB+timers\fP, \fB+kaspdb\fP, +\fB+keysonly\fP, \fB+catalog\fP, \fB+quic\fP, and their negative counterparts +\fB+nozonefile\fP, \fB+nojournal\fP, \fB+notimers\fP, \fB+nokaspdb\fP, \fB+nokeysonly\fP, +\fB+nocatalog\fP, and \fB+noquic\fP\&. With these filters set, zone contents, +zone\(aqs journal, zone\-related timers, zone\-related data in the KASP database +together with keys (or keys without the KASP database), zone\(aqs catalog, +and the server QUIC key and certificate, respectively, are backed up, +or omitted from the backup. By default, filters \fB+zonefile\fP, \fB+timers\fP, +\fB+kaspdb\fP, \fB+nokeysonly\fP, \fB+catalog\fP, \fB+quic\fP, and \fB+nojournal\fP +are set for backup. The same defaults are set for restore, with the only +difference being \fB+noquic\fP\&. Setting a filter for an item doesn\(aqt change +default settings for other items. If zone flushing is disabled, the original +zone file is backed up instead of writing out zone contents to a file. +When backing\-up a catalog zone, it is recommended to prevent ongoing changes +to it by use of \fBzone\-freeze\fP\&. +See \fI\%Notes\fP below about the directory permissions. (#) +.TP +\fBzone\-restore\fP [\fIzone\fP\&...] \fB+backupdir\fP \fIdirectory\fP [\fIfilter\fP\&...] +Trigger a zone data and metadata restore from a specified backup directory. +Optional filters are equivalent to the same filters of \fBzone\-backup\fP\&. +Restore from backups created by Knot DNS releases prior to 3.1 is possible +with the force option. See \fI\%Notes\fP below about the directory +permissions. (#) +.TP +\fBzone\-sign\fP [\fIzone\fP\&...] +Trigger a DNSSEC re\-sign of the zone. Existing signatures will be dropped. +This command is valid for zones with DNSSEC signing enabled. (#) +.TP +\fBzone\-keys\-load\fP [\fIzone\fP\&...] +Trigger a load of DNSSEC keys and other signing material from KASP database +(which might have been altered manually). If suitable, re\-sign the zone +afterwards (keeping valid signatures intact). (#) +.TP +\fBzone\-key\-rollover\fP \fIzone\fP \fIkey_type\fP +Trigger immediate key rollover. Publish new key and start a key rollover, +even when the key has a lifetime to go. Key type can be \fBksk\fP (also for CSK) +or \fBzsk\fP\&. This command is valid for zones with DNSSEC signing and automatic +key management enabled. Note that complete key rollover consists of several steps +and the blocking mode relates to the initial one only! (#) +.TP +\fBzone\-ksk\-submitted\fP \fIzone\fP\&... +Use when the zone\(aqs KSK rollover is in submission 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. (#) +.TP +\fBzone\-freeze\fP [\fIzone\fP\&...] +Trigger a zone freeze. All running events will be finished and all new and pending +(planned) zone\-changing events (load, refresh, update, flush, and DNSSEC signing) +will be held up until the zone is thawed. (#) +.TP +\fBzone\-thaw\fP [\fIzone\fP\&...] +Trigger dismissal of zone freeze. (#) +.TP +\fBzone\-xfr\-freeze\fP [\fIzone\fP\&...] +Temporarily disable outgoing AXFR/IXFR for the zone(s). (#) +.TP +\fBzone\-xfr\-thaw\fP [\fIzone\fP\&...] +Dismiss outgoing XFR freeze. (#) +.TP +\fBzone\-read\fP \fIzone\fP [\fIowner\fP [\fItype\fP]] +Get zone data that are currently being presented. +.TP +\fBzone\-begin\fP \fIzone\fP\&... +Begin a zone transaction. +.TP +\fBzone\-commit\fP \fIzone\fP\&... +Commit the zone transaction. All changes are applied to the zone. +.TP +\fBzone\-abort\fP \fIzone\fP\&... +Abort the zone transaction. All changes are discarded. +.TP +\fBzone\-diff\fP \fIzone\fP +Get zone changes within the transaction. +.TP +\fBzone\-get\fP \fIzone\fP [\fIowner\fP [\fItype\fP]] +Get zone data within the transaction. +.TP +\fBzone\-set\fP \fIzone\fP \fIowner\fP [\fIttl\fP] \fItype\fP \fIrdata\fP +Add zone record within the transaction. The first record in a rrset +requires a ttl value specified. +.TP +\fBzone\-unset\fP \fIzone\fP \fIowner\fP [\fItype\fP [\fIrdata\fP]] +Remove zone data within the transaction. +.TP +\fBzone\-purge\fP \fIzone\fP\&... [\fB+orphan\fP] [\fIfilter\fP\&...] +Purge zone data, zone file, journal, timers, and/or KASP data of specified zones. +Available filters are \fB+expire\fP, \fB+zonefile\fP, \fB+journal\fP, \fB+timers\fP, +\fB+kaspdb\fP, and \fB+catalog\fP\&. If no filter is specified, all filters are enabled. +If the zone is no longer configured, add \fB+orphan\fP parameter (zone file cannot +be purged in this case). When purging orphans, always check the server log for +possible errors. For proper operation, it\(aqs necessary to prevent ongoing changes +to the zone and triggering of zone related events during purge; use of +\fBzone\-freeze\fP is advisable. This command always requires the force option. (#) +.TP +\fBzone\-stats\fP \fIzone\fP [\fImodule\fP[\fB\&.\fP\fIcounter\fP]] +Show zone statistics counter(s). To print also counters with value 0, use +force option. +.TP +\fBconf\-init\fP +Initialize the configuration database. If the database doesn\(aqt exist yet, +execute this command as an intended user to ensure the server is permitted +to access the database (e.g. \fIsudo \-u knot knotc conf\-init\fP). (*) +.TP +\fBconf\-check\fP +Check the server configuration. (*) +.TP +\fBconf\-import\fP \fIfilename\fP [+nopurge] +Import a configuration file into the configuration database. If the database +doesn\(aqt exist yet, execute this command as an intended user to ensure the server +is permitted to access the database (e.g. \fIsudo \-u knot knotc conf\-import ...\fP). +An optional filter \fB+nopurge\fP prevents possibly existing configuration +database from purging before the import itself. +Also ensure the server is not using the configuration database at the same time! (*) +.TP +\fBconf\-export\fP [\fIfilename\fP] +Export the configuration database into a config file or stdout. (*) +.TP +\fBconf\-list\fP [\fIitem\fP] +List the configuration database sections or section items. +.TP +\fBconf\-read\fP [\fIitem\fP] +Read the item from the active configuration database. +.TP +\fBconf\-begin\fP +Begin a writing configuration database transaction. Only one transaction +can be opened at a time. +.TP +\fBconf\-commit\fP +Commit the configuration database transaction. +.TP +\fBconf\-abort\fP +Rollback the configuration database transaction. +.TP +\fBconf\-diff\fP [\fIitem\fP] +Get the item difference in the transaction. +.TP +\fBconf\-get\fP [\fIitem\fP] +Get the item data from the transaction. +.TP +\fBconf\-set\fP \fIitem\fP [\fIdata\fP\&...] +Set the item data in the transaction. +.TP +\fBconf\-unset\fP [\fIitem\fP] [\fIdata\fP\&...] +Unset the item data in the transaction. +.UNINDENT +.SS Notes +.sp +Empty or \fB\-\-\fP \fIzone\fP parameter means all zones or all zones with a transaction. +.sp +Use \fB@\fP \fIowner\fP to denote the zone name. +.sp +Type \fIitem\fP parameter in the form of \fIsection\fP[\fB[\fP\fIid\fP\fB]\fP][\fB\&.\fP\fIname\fP]. +.sp +(*) indicates a local operation which requires a configuration. +.sp +(#) indicates an optionally blocking operation. +.sp +The \fB\-b\fP and \fB\-f\fP options can be placed right after the command name. +.sp +Responses returned by \fIknotc\fP commands depend on the mode: +.INDENT 0.0 +.IP \(bu 2 +In the blocking mode, \fIknotc\fP reports if an error occurred during processing +of the command by the server. If an error is reported, a more detailed information +about the failure can usually be found in the server log. +.IP \(bu 2 +In the non\-blocking (default) mode, \fIknotc\fP doesn\(aqt report processing errors. +The \fIOK\fP response to triggering commands means that the command has been successfully +sent to the server. To verify if the operation succeeded, it\(aqs necessary to +check the server log. +.UNINDENT +.sp +Actions \fBzone\-flush\fP, \fBzone\-backup\fP, and \fBzone\-restore\fP are carried out by +the \fIknotd\fP process. The directory specified must be accessible to the user account +that \fIknotd\fP runs under and if the directory already exists, its permissions must be +appropriate for that user account. +.SS Interactive mode +.sp +The utility provides interactive mode with basic line editing functionality, +command completion, and command history. +.sp +Interactive mode behavior can be customized in \fI~/.editrc\fP\&. Refer to +\fBeditrc(5)\fP for details. +.sp +Command history is saved in \fI~/.knotc_history\fP\&. +.SH EXIT VALUES +.sp +Exit status of 0 means successful operation.
