NAME

       pdns_recursor - high-performance, simple and secure recursing nameserver

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_recursor --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/powerdns by default.

       --daemon
              Operate as a daemon.

       --delegation-only
              Which domains we only accept delegations from (a Verisign special).

       --entropy-source=FILE
              Read new entropy from FILE, defaults to /dev/urandom.

       --export-etc-hosts
              If set, this flag will export the hostnames and IP addresses mentioned in /etc/hosts.

       --forward-zones=ZONENAME=ADDRESS[,ZONENAME=ADDRESS]...
              Queries for ZONENAME will be forwarded to ADDRESS.   ADDRESS  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'.

       --quiet
              Suppress logging of questions and answers.

       --server-id=TEXT
              Return TEXT when queried for 'server.id' TXT, defaults to hostname.

       --serve-rfc1918
              On  by   default,   this   makes   the   server   authoritatively   aware   of:   10.in-addr.arpa,
              168.192.in-addr.arpa   and   16-31.172.in-addr.arpa,  which  saves  load  on  the  AS112  servers.
              Individual parts of these zones can still be loaded or forwarded.

       --setgid=GID
              If set, change group id to GID for more security.

       --setuid=UID
              If set, change user id to UID for more security.

       --single-socket
              If set, only use a single socket for outgoing queries.

       --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.

       --version-string=TEXT
              TEXT will be reported on version.pdns or version.bind queries.
