Simon Kelley9e4abcb2004-01-22 19:47:41 +00001# Configuration file for dnsmasq.

3# Format is one option per line, legal options are the same
4# as the long options legal on the command line. See
5# "/usr/sbin/dnsmasq --help" or "man 8 dnsmasq" for details.
6
7# Change these lines if you want dnsmasq to serve MX records.
8# Only one of mx-host and mx-target need be set, the other defaults
9# to the name of the host running dnsmasq.
10#mx-host=
11#mx-target=
12#selfmx
13#localmx
14
15# The following three options make you a better netizen, since they
16# tell dnsmasq to filter out queries which the public DNS cannot
17# answer, and which load the servers (especially the root servers)
18# uneccessarily. If you have a dial-on-demand link they also stop
19# these requests from bringing up the link uneccessarily.

31# somewhere other that /etc/resolv.conf
32#resolv-file=
33
Simon Kelley1ab84e22004-01-29 16:48:35 +000034# By default, dnsmasq will send queries to any of the upstream
35# servers it knows about and tries to favour servers to are known
36# to be up. Uncommenting this forces dnsmasq to try each query
37# with each server strictly in the order they appear in
38# /etc/resolv.conf
39#strict-order
40
Simon Kelley9e4abcb2004-01-22 19:47:41 +000041# If you don't want dnsmasq to read /etc/resolv.conf or any other
42# file, getting its servers for this file instead (see below), then
43# uncomment this
44#no-resolv
45
46# If you don't want dnsmasq to poll /etc/resolv.conf or other resolv
47# files for changes and re-read them then uncomment this.
48#no-poll
49
50# Add other name servers here, with domain specs if they are for
51# non-public domains.
52#server=/localnet/192.168.0.1
53
54# Add local-only domains here, queries in these domains are answered
55# from /etc/hosts or DHCP only.
56#local=/localnet/
57
58# Add domains which you want to force to an IP address here.
59# The example below send any host in doubleclick.net to a local
60# webserver.
61#address=/doubleclick.net/127.0.0.1
62
63# You no longer (as of version 1.7) need to set these to enable
64# dnsmasq to read /etc/ppp/resolv.conf since dnsmasq now uses the
65# "dip" group to achieve this.
66#user=
67#group=
68
69# If you want dnsmasq to listen for requests only on specified interfaces
70# (and the loopback) give the name of the interface (eg eth0) here.
71# Repeat the line for more than one interface.
72#interface=
73# Or you can specify which interface _not_ to listen on
74#except-interface=
75# Or which to listen on by address (remember to include 127.0.0.1 if
76# you use this.)
77#listen-address=
78
Simon Kelley44a2a312004-03-10 20:04:35 +000079# On systems which support it, dnsmasq binds the wildcard address,
80# even when it is listening on only some interfaces. It then discards
81# requests that it shouldn't reply to. This has the advantage of
82# working even when interfaces come and go and change address. If you
83# want dnsmasq to really bind only the interfaces it is listening on,
84# uncomment this option. About the only time you may need this is when
85# running another nameserver on the same machine.

Simon Kelley9e4abcb2004-01-22 19:47:41 +000088# If you don't want dnsmasq to read /etc/hosts, uncomment the

92# this.
93#addn-hosts=/etc/banner_add_hosts

100# does the following things.
101# 1) Allows DHCP hosts to have fully qualified domain names, as long
102# as the domain part matches this setting.
103# 2) Sets the "domain" DHCP option thereby potentially setting the
104# domain of all systems configured by DHCP
105# 3) Provides the domain part for "expand-hosts"
