Synopsis
--------

Description
-----------
Knot DNS is a high-performance authoritative DNS server. The `knotd` program is
the DNS server daemon.

Use a textual configuration file (default is :file:`@config_dir@/knot.conf`).
**-C**, **--confdb** *directory*
Use a binary configuration database directory (default is :file:`@storage_dir@/confdb`).
The default configuration database, if exists, has a preference to the default
configuration file.
**-m**, **--max-conf-size** *MiB*
Set maximum size of the configuration database
(default is @conf_mapsize@ MiB, maximum 10000 MiB).
**-s**, **--socket** *path*
Use a remote control UNIX socket path (default is :file:`@run_dir@/knot.sock`).
**-d**, **--daemonize** [*directory*]
Run the server as a daemon. New root directory may be specified

Signals
.......
If the `knotd` process receives a SIGHUP signal, it reloads its configuration and
reopens the log files, if they are configured. When `knotd` receives a SIGUSR1
signal, it reloads all configured zones. Upon receiving a SIGINT signal, `knotd`
exits.
Exit values
-----------
Exit status of 0 means successful operation. Any other exit status indicates
an error.
