11
13 pdns_recursor(1) is a high performance, simple and secure recursing
14 nameserver. It currently powers over two million internet connections.
15 The recursor is configured via a configuration file, but each item in
17 that file can be overridden on the command line.
18 This manpage lists the core set of features needed to get the PowerDNS
20 recursor working, for full and up to date details head to
21 http://doc.powerdns.com/built-in-recursor.html
22
24 To listen on 1.2.3.4 and allow the 1.2.3.0/8 subnet to recurse, and run
25 as a daemon, execute:
26 # pdns_recursor --local-address=1.2.3.4 --allow-from=1.2.3.0/8 --daemon
28 To stop the recursor by hand, run:
30 # rec_control quit
32 Alternatively, use the init.d script provided.
34
36 For authoritative listing of options, consult the documentation
37 referenced above.
38 --aaaa-additional-processing
40 turn on to do AAAA additional processing (slow)
41 --allow-from
43 If set, only allow these comma separated netmasks to recurse
44 --auth-can-lower-ttl
46 Authoritative zones can transmit a TTL value that is lower than
47 that specified in the parent zone. This is called a delegation
48 inconsistency. To follow RFC 2181 paragraphs 5.2 and 5.4 to the
49 letter, enable this feature. This will mean a slight deterioration
50 of performance, and it will not solve any problems, but does make
51 the recursor more standards compliant. Not recommended unless you
52 have to tick an RFC 2181 compliant box. Off by default.
53 --auth-zones
55 Comma separated list of zonename=filename pairs. Zones read from
56 these files are served authoritatively. Example: auth-zones=
57 ds9a.nl=/var/zones/ds9a.nl, powerdns.com=/var/zones/powerdns.com.
58 Available since 3.1.
59 --chroot
61 switch to chroot jail
62 --client-tcp-timeout
64 Timeout in seconds when talking to TCP clients
65 --config-dir
67 Location of configuration directory (recursor.conf)
68 --daemon
70 Operate as a daemon
71 --delegation-only
73 Which domains we only accept delegations from
74 --entropy-source
76 Where to read new entropy from, defaults to /dev/urandom.
77 --export-etc-hosts
79 If set, this flag will export the host names and IP addresses
80 mentioned in /etc/hosts. Available since 3.1.
81 --fork
83 If set, fork the daemon for possible double performance
84 --forward-zones
86 Comma separated list of zonename=IP pairs. Queries for zones listed
87 here will be forwarded to the IP address listed. forward-zones=
88 ds9a.nl=213.244.168.210, powerdns.com=127.0.0.1. Available since
89 3.1. For more details, see the manual.
90 --forward-zones-file
92 listed here will be forwarded to the IP address listed. One zone
93 per line, like: ds9a.nl=213.244.168.210 Available since 3.1.5. For
94 more details, see the manual.
95 --hint-file
97 If set, load root hints from this file
98 --local-address
100 IP addresses to listen on, separated by spaces or commas
101 --local-port
103 port to listen on
104 --log-common-errors
106 If we should log rather common errors
107 --max-cache-entries
109 If set, maximum number of entries in the main cache
110 --max-negative-ttl
112 maximum number of seconds to keep a negative cached entry in memory
113 --max-tcp-clients
115 Maximum number of simultaneous TCP clients
116 --max-tcp-per-client
118 If set, maximum number of TCP sessions per client (IP address)
119 --query-local-address
121 Source IP address for sending queries
122 --query-local-address6
124 Send out local IPv6 queries from this address. Disabled by default,
125 which also disables outgoing IPv6 support. A useful setting is ::0.
126 --quiet
128 Suppress logging of questions and answers
129 --remotes-ringbuffer-entries
131 maximum number of packets to store statistics for
132 --server-id
134 Returned when queried for server.id TXT, defaults to hostname
135 --serve-rfc1918
137 On by default, this makes the server authoritatively aware of:
138 10.in-addr.arpa, 168.192.in-addr.arpa and 16-31.172.in-addr.arpa,
139 which saves load on the AS112 servers. Individual parts of these
140 zones can still be loaded or forwarded.
141 --setgid
143 If set, change group id to this gid for more security
144 --setuid
146 If set, change user id to this uid for more security
147 --single-socket
149 If set, only use a single socket for outgoing queries
150 --socket-dir
152 Where the controlsocket will live
153 --spoof-nearmiss-max
155 If non-zero, assume spoofing after this many near misses
156 --trace
158 if we should output heaps of logging
159 --version-string
161 string reported on version.pdns or version.bind
162
164 None known. File new ones at http://wiki.powerdns.com.
