pdns_recursor

       nameserver

SYNOPSIS
       pdns_recursor [--daemon] [--local-address] [--help, -h] [--allow-from]

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 1.2.3.4 and allow the 1.2.3.0/8 subnet to recurse, and run
       as a daemon, execute:

           # pdns_recursor --local-address=1.2.3.4 --allow-from=1.2.3.0/8 --daemon

       To stop the recursor by hand, run:

           # rec_control quit

           Alternatively, use the init.d script provided.

OPTIONS
       For authoritative listing of options, consult the documentation
       referenced above.

       --aaaa-additional-processing
           turn on to do AAAA additional processing (slow)

       --allow-from
           If set, only allow these comma separated netmasks to recurse

       --auth-can-lower-ttl
           Authoritative zones can transmit a TTL value that is lower than
           that specified in the parent zone. This is called a delegation
           inconsistency. To follow RFC 2181 paragraphs 5.2 and 5.4 to the
           letter, enable this feature. This will mean a slight deterioration
           of performance, and it will not solve any problems, but does make
           the recursor more standards compliant. Not recommended unless you
           have to tick an RFC 2181 compliant box. Off by default.

       --auth-zones
           Comma separated list of zonename=filename pairs. Zones read from
           these files are served authoritatively. Example: auth-zones=
           ds9a.nl=/var/zones/ds9a.nl, powerdns.com=/var/zones/powerdns.com.
           Available since 3.1.

       --chroot
           Which domains we only accept delegations from

       --entropy-source
           Where to read new entropy from, defaults to /dev/urandom.

       --export-etc-hosts
           If set, this flag will export the host names and IP addresses
           mentioned in /etc/hosts. Available since 3.1.

       --fork
           If set, fork the daemon for possible double performance

       --forward-zones
           Comma separated list of zonename=IP pairs. Queries for zones listed
           here will be forwarded to the IP address listed. forward-zones=
           ds9a.nl=213.244.168.210, powerdns.com=127.0.0.1. Available since
           3.1. For more details, see the manual.

       --forward-zones-file
           listed here will be forwarded to the IP address listed. One zone
           per line, like: ds9a.nl=213.244.168.210 Available since 3.1.5. For
           more details, see the manual.

       --hint-file
           If set, load root hints from this file

       --local-address
           IP addresses to listen on, separated by spaces or commas

       --local-port
           port to listen on

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

       --max-cache-entries
           If set, maximum number of entries in the main cache

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

       --max-tcp-clients
           Maximum number of simultaneous TCP clients

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

       --query-local-address
           Source IP address for sending queries

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

           which saves load on the AS112 servers. Individual parts of these
           zones can still be loaded or forwarded.

       --setgid
           If set, change group id to this gid for more security

       --setuid
           If set, change user id to this uid for more security

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

       --socket-dir
           Where the controlsocket will live

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

       --trace
           if we should output heaps of logging

       --version-string
           string reported on version.pdns or version.bind
