pdns_recursor

SYNOPSIS
       pdns_recursor [OPTION]...

DESCRIPTION
       pdns_recursor(1) is a high performance,  simple  and  secure  recursing
       nameserver.  It currently powers over two million internet connections.

       The  recursor  is configured via a configuration file, but each item in
       that file can be overridden on the command line.

       This manpage lists the core set of features needed to get the  PowerDNS
       recursor   working,   for   full   and  up  to  date  details  head  to
       http://doc.powerdns.com/built-in-recursor.html

EXAMPLES
       To listen on 192.0.2.53 and allow the 192.0.2.0/24 subnet  to  recurse,
       and run as a daemon, execute:

       # pdns_recur-
       sor --local-address=192.0.2.53 --allow-from=192.0.2.0/24 --daemon

       To stop the recursor by hand, run:

       # rec_control quit

       However, the recommended way of starting and stopping the  recursor  is
       to use the init.d script provided.

OPTIONS
       For  authoritative listing of options, consult the online documentation
       at http://doc.powerdns.com/md/recursor/settings/

       --allow-from=NETWORK[,NETWORK]...
              If set, only allow these comma separated NETWORKs, with  network
              mask to recurse.  For example: 192.0.2.0/24,203.0.113.128/25.

       --auth-zones=ZONENAME=FILENAME[,ZONENAME=FILENAME]...
              Serve  ZONENAME  from  FILENAME  authoritatively.   For example:
              ds9a.nl=/var/zones/ds9a.nl,powerdns.com=/var/zones/powerdns.com.

       --chroot=DIRECTORY
              chroot the process to DIRECTORY.

       --client-tcp-timeout=NUM
              Timeout in seconds when talking to TCP clients.

       --config-dir=DIRECTORY
              Location of configuration directory  (recursor.conf),  /etc/pow-
              erdns by default.

       --daemon
              Operate as a daemon.

       --delegation-only
              should be an IP address, not a hostname (to prevent chicken  and
              egg problems).  Example: forward-zones= ds9a.nl=213.244.168.210,
              powerdns.com=127.0.0.1.

       --forward-zones-file=FILENAME
              Similar to --forward-zones, but read the options from  FILENAME.
              FILENAME    should    contain   one   zone   per   line,   like:
              ds9a.nl=213.244.168.210.

       --help Show a summary of options.

       --hint-file=FILENAME
              Load root hints from this FILENAME

       --local-address=ADDRESS[,ADDRESS]...
              Listen on ADDRESS, separated by spaces or commas.

       --local-port=PORT
              Listen on PORT.

       --log-common-errors
              If we should log rather common errors.

       --max-cache-entries=NUM
              Maximum number of entries in the main cache.

       --max-negative-ttl=NUM
              maximum number of seconds to keep a  negative  cached  entry  in
              memory.

       --max-tcp-clients=NUM
              Maximum number of simultaneous TCP clients.

       --max-tcp-per-client
              If set, maximum number of TCP sessions per client (IP address).

       --query-local-address=ADDRESS
              Use ADDRESS as Source IP address when sending queries.

       --query-local-address6=ADDRESS
              Send  out local IPv6 queries from ADDRESS.  Disabled by default,
              which also disables outgoing IPv6 support.  A useful setting  is
              '::0'.

       --socket-dir=DIRECTORY
              The controlsocket will live in DIRECTORY.

       --spoof-nearmiss-max=NUM
              If non-zero, assume spoofing after this many near misses.

       --trace
              if we should output heaps of logging.
