Name

rec_control - control pdns_recursor

rec_control [--help] [--socket-dir] [--socket-pid] command ..

rec_control(1) allows the operator to control a running instance of the pdns_recursor.

The commands that can be passed to the recursor are described on http://doc.powerdns.com/rec-control.html

To stop the recursor by hand, run:

# rec_control quit

To dump the cache to disk, execute:

# rec_control dump-cache /tmp/the-cache

--help

provide this helpful message
--socket-dir: Where the controlsocket will live
--socket-pid: When running in SMP mode, pid of pdns_recursor to control
--timeout: Number of seconds to wait for the remote PowerDNS Recursor to respond. Set to 0 for infinite.

dump-cache filename

Dumps the entire cache to the filename mentioned. This file should not exist already, PowerDNS will refuse to overwrite it. While dumping, the recursor will not answer questions.
get statistic: Retrieve a statistic. For items that can be queried, see http://doc.powerdns.com/recursor-stats.html
get-all: Retrieve all known statistics.
ping: Check if server is alive.
quit: Request shutdown of the recursor
reload-zones: Reload authoritative and forward zones. Retains current configuration in case of errors.
top-remotes: Shows the top-20 most active remote hosts. Statistics are over the last remotes-ringbuffer-entries queries, which defaults to 0.
wipe-cache domain0 [domain1]: Wipe entries from the cache. This is useful if, for example, an important server has a new IP address, but the TTL has not yet expired. Multiple domain names can be passed. Note that you must terminate a domain with a .! So to wipe powerdns.org, issue rec_control wipe-cache powerdns.org.. Versions beyond 3.1 don't need the trailing dot. Consider not only wiping www.domain.com. but also domain.com., as the cached nameservers or target of CNAME may continue to be undesired.

None known. File new ones at http://wiki.powerdns.com.
