+.SS Commands
+.INDENT 0.0
+.TP
+\fBlist\fP [\fItimestamp_format\fP]
+Prints the list of key IDs and parameters of keys belonging to the zone.
+.TP
+\fBgenerate\fP [\fIarguments\fP\&...]
+Generates new DNSSEC key and stores it in KASP database. Prints the key ID.
+This action takes some number of arguments (see below). Values for unspecified arguments are taken
+from corresponding policy (if \fI\-c\fP or \fI\-C\fP options used) or from Knot policy defaults.
+.TP
+\fBimport\-bind\fP \fIBIND_key_file\fP
+Imports a BIND\-style key into KASP database (converting it to PEM format).
+Takes one argument: path to BIND key file (private or public, but both MUST exist).
+.TP
+\fBimport\-pub\fP \fIBIND_pubkey_file\fP
+Imports a public key into KASP database. This key won\(aqt be rolled over nor used for signing.
+Takes one argument: path to BIND public key file.
+.TP
+\fBimport\-pem\fP \fIPEM_file\fP [\fIarguments\fP\&...]
+Imports a DNSSEC key from PEM file. The key parameters (same as for the generate action) need to be
+specified (mainly algorithm, timers...) because they are not contained in the PEM format.
+.TP
+\fBimport\-pkcs11\fP \fIkey_id\fP [\fIarguments\fP\&...]
+Imports a DNSSEC key from PKCS #11 storage. The key parameters (same as for the generate action) need to be
+specified (mainly algorithm, timers...) because they are not available. In fact, no key
+data is imported, only KASP database metadata is created.
+.TP
+\fBnsec3\-salt\fP [\fInew_salt\fP]
+Prints the current NSEC3 salt used for signing. If \fInew_salt\fP is specified, the salt is overwritten.

+.TP
+\fBlocal\-serial\fP [\fInew_serial\fP]
+Print SOA serial stored in KASP database when using on\-secondary DNSSEC signing.
+If \fInew_serial\fP is specified, the serial is overwritten. After updating the serial, expire the zone
+(\fBzone\-purge +expire +zonefile +journal\fP) if the server is running, or remove corresponding zone file
+and journal contents if the server is stopped.
+.TP
+\fBmaster\-serial\fP [\fInew_serial\fP]
+Print SOA serial of the remote master stored in KASP database when using on\-secondary DNSSEC signing.
+If \fInew_serial\fP is specified, the serial is overwritten (not recommended).
+.TP
+\fBset\fP \fIkey_spec\fP [\fIarguments\fP\&...]
+Changes a timing argument (or ksk/zsk) of an existing key to a new value. \fIKey_spec\fP is either the
+key tag or a prefix of the key ID, with an optional \fI[id=|keytag=]\fP prefix; \fIarguments\fP
+are like for \fBgenerate\fP, but just the related ones.
+.TP
+\fBds\fP [\fIkey_spec\fP]
+Generate DS record (all digest algorithms together) for specified key. \fIKey_spec\fP
+is like for \fBset\fP, if unspecified, all KSKs are used.

+.sp
+The configuration consists of several fixed sections and optional module
+sections. There are 16 fixed sections (\fBmodule\fP, \fBserver\fP, \fBxdp\fP, \fBcontrol\fP,
+\fBlog\fP, \fBstatistics\fP, \fBdatabase\fP, \fBkeystore\fP, \fBkey\fP, \fBremote\fP,
+\fBremotes\fP, \fBacl\fP, \fBsubmission\fP, \fBpolicy\fP, \fBtemplate\fP, \fBzone\fP).
+Module sections are prefixed with the \fBmod\-\fP prefix (e.g. \fBmod\-stats\fP).
+.sp
+Most of the sections (e.g. \fBzone\fP) are sequences of settings blocks. Each
+settings block begins with a unique identifier, which can be used as a reference
+from other sections (such an identifier must be defined in advance).
+.sp
+A multi\-valued item can be specified either as a YAML sequence:

+If an item value contains spaces or other special characters, it is necessary
+to enclose such a value within double quotes \fB"\fP \fB"\fP\&.
+.SH COMMENTS
+.sp
+A comment begins with a \fB#\fP character and is ignored during processing.
+Also each configuration section or sequence block allows a permanent
+comment using the \fBcomment\fP item which is stored in the server beside the
+configuration.

+.sp
+\fIDefault:\fP \fB5000\fP (milliseconds)
+.SS tcp\-reuseport
+.sp
+If enabled, each TCP worker listens on its own socket and the OS kernel
+socket load balancing is employed using SO_REUSEPORT (or SO_REUSEPORT_LB
+on FreeBSD). Due to the lack of one shared socket, the server can offer
+higher response rate processing over TCP. However, in the case of
+time\-consuming requests (e.g. zone transfers of a TLD zone), enabled reuseport
+may result in delayed or not being responded client requests. So it is
+advisable to use this option on secondary servers.

+Change of this parameter requires restart of the Knot server to take effect.
+.sp
+\fIDefault:\fP \fBoff\fP
+.SS tcp\-fastopen
+.sp
+If enabled, use TCP Fast Open for outbound TCP communication (client side):
+incoming zone transfers, sending NOTIFY, and DDNS forwarding. This mode simplifies
+TCP handshake and can result in better networking performance. TCP Fast Open
+for inbound TCP communication (server side) isn\(aqt affected by this

+.SH SYNOPSIS
+.sp
+\fBknotc\fP [\fIparameters\fP] \fIaction\fP [\fIaction_args\fP]
+.SH DESCRIPTION
+.sp
+This program controls a running \fIknotd\fP process using a socket.
+.sp
+If an \fIaction\fP is specified, it is performed and \fIknotc\fP exits, otherwise the program
+is executed in the interactive mode.
+.SS Options
+.INDENT 0.0
+.TP
+\fB\-c\fP, \fB\-\-config\fP \fIfile\fP
+Use a textual configuration file (default is \fB@config_dir@/knot.conf\fP).
+.TP
+\fB\-C\fP, \fB\-\-confdb\fP \fIdirectory\fP
+Use a binary configuration database directory (default is \fB@storage_dir@/confdb\fP).
+The default configuration database, if exists, has a preference to the default
+configuration file.
+.TP
+\fB\-m\fP, \fB\-\-max\-conf\-size\fP \fIMiB\fP
+Set maximum size of the configuration database
+(default is @conf_mapsize@ MiB, maximum 10000 MiB).
+.TP
+\fB\-s\fP, \fB\-\-socket\fP \fIpath\fP
+Use a control UNIX socket path (default is \fB@run_dir@/knot.sock\fP).
+.TP
+\fB\-t\fP, \fB\-\-timeout\fP \fIseconds\fP
+Use a control timeout in seconds. Set to 0 for infinity (default is 60).
+The control socket operations are also subject to the timeout
+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,
+or \fBconfigure\fP for the configure summary.
+.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+catalog\fP, and their negative counterparts \fB+nozonefile\fP, \fB+nojournal\fP,
+\fB+notimers\fP, \fB+nokaspdb\fP, and \fB+nocatalog\fP\&. With these filters set,
+zone contents, zone\(aqs journal, zone related timers, zone related data in the
+KASP database together with keys, and zone\(aqs catalog, respectively, are backed up,
+or omitted from the backup. By default, filters \fB+zonefile\fP, \fB+timers\fP,
+\fB+kaspdb\fP, \fB+catalog\fP, and \fB+nojournal\fP are set. Setting a filter
+for an item doesn\(aqt change default settings for other items. If zone flushing
+is disabled, original zone file is backed up instead of writing out zone
+contents to a file. 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. 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
+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).
+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\&.
