REC_CONTROL(8)

NAME
rec_control - control pdns_recursor

SYNOPSIS

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

DESCRIPTION

rec_control(8) 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

EXAMPLES

To stop the recursor by hand, run:

    # rec_control quit

To dump the cache to disk, execute:

    # rec_control dump-cache /tmp/the-cache

OPTIONS

--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.

COMMANDS

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.
