PDNS_RECURSOR(1) [FIXME: manual] PDNS_RECURSOR(1)
NAME
pdns_recursor - high-performance, simple and secure recursing 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
switch to chroot jail
--client-tcp-timeout
Timeout in seconds when talking to TCP clients
--config-dir
Location of configuration directory (recursor.conf)
--daemon
Operate as a daemon
--delegation-only
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.
--quiet
Suppress logging of questions and answers
--remotes-ringbuffer-entries
maximum number of packets to store statistics for
--server-id
Returned 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
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
