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.
