NAME

       pdns_recursor - The PowerDNS Recursor binary

SYNOPSIS

       pdns_recursor [OPTION]...

DESCRIPTION

       pdns_recursor is a high performance, simple and secure recursing nameserver. It currently powers hundreds
       of millions 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 https://doc.powerdns.com/.

EXAMPLES

       To listen on 192.0.2.53 and allow the 192.0.2.0/24 subnet to recurse,  and  run  as  in  the  background,
       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 or
       systemctl(1).

OPTIONS

       For authoritative listing of options, consult the online documentation at <https://doc.powerdns.com/>

       --allow-from=<networks>
              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=<authzones>
              Where  authzone  is  <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), the default depends on the SYSCONFDIR  option
              at  build-time,  which  is  usually  /etc/powerdns.  The  default  can be found with pdns_recursor
              --config | grep ' config-dir='.

       --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=<forwardzones>
              Where forwardzone is <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>
              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=<num>
              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 'id.server' 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.
