pdns_control - Control the PowerDNS nameserver


pdns_control [OPTION]... COMMAND


pdns_control is used to send commands to a running PowerDNS nameserver.


--help : Show summary of options.

--chroot=DIR : Directory where PowerDNS is chrooted.

--config-dir=DIR : Location of configuration directory (pdns.conf).

--config-name=NAME : Name of this virtual configuration - will rename the binary image.

--remote-address=ADDRESS : Remote address to query.

--remote-port=PORT : Remote port to query.

--secret=SECRET : Secret needed to connect to remote PowerDNS.

--socket-dir=DIR : Where the controlsocket lives.


bind-add-zone DOMAIN FILENAME : When using the bindbackend, add a zone. This zone is added in-memory and served immediately. Note that this does not add the zone to the bind-config file. FILENAME must be an absolute path.

bind-domain-status [DOMAIN...] : When using the bindbackend, list status of all domains. Optionally, append DOMAINs to get the status of specific zones.

bind-list-rejects : When using the bindbackend, get a list of all rejected domains.

bind-reload-now DOMAIN [DOMAIN...] : When using the bindbackend, immediately reload DOMAIN from disk.

ccounts : Show the content of the cache.

current-config : Show the currently running configuration. The output has the same format as pdns_server --config. You'll notice that all the are uncommented. This is because PowerDNS simply has values, and the default isn't known at runtime.

cycle : Restart the nameserver so it reloads its configuration. Only works when the server is running in guardian mode.

list : Dump all variables and their values in a comma separated list, equivalent to show *.

list-zones [master,slave,native] : Show a list of zones, optionally filter on the type of zones to show.

notify DOMAIN : Adds DOMAIN to the notification list, causing PowerDNS to send out notifications to the nameservers of a domain. Can be used if a slave missed previous notifications or is generally hard of hearing. Use * to notify for all domains. (Note that you may need to escape the * sign in your shell.)

notify-host DOMAIN ADDRESS : Same as above but with operator specified IP ADDRESS as destination, to be used if you know better than PowerDNS.

ping, rping : Check if the server is still alive. Will return 'PONG' when it is. ping works when running inside a guardian, whereas rping works when running without a guardian.

purge [RECORD] : Purge entries from the cache. If RECORD ends with a dollar ($) all entries that end with that name are removed. If no record is specified the entire cache is purged.

qtypes : Get a count of queries per qtype on standard out.

quit : Tell a running pdns_server to quit.

rediscover : Instructs backends that new domains may have appeared in the database, or, in the case of the Bind backend, in named.conf.

reload : Instruct the server to reload all its zones, this will not add new zones.

remotes : Get the top number of remote addresses (clients).

respsizes : Get a histogram of the response sizes.

retrieve DOMAIN : Retrieve slave DOMAIN from its master. Done nearly immediately.

set VARIABLE VALUE : Set the configuration parameter VARIABLE to VALUE. Currently only the query-logging can be set.

show VARIABLE : Show a single statistic, as present in the output of the list command.

status : Show usage statistics. This only works if the server is running in guardian mode.

token-login MODULE SLOT PIN : Log on to a PKCS#11 slot. You only need to login once per slot, even if you have multiple keys on single slot. Only available if PowerDNS was compiled with PKCS#11 support.

uptime : Show the uptime of the running server.

version : Print the version of the running pdns daemon.
