1 # Configuration file for dnsmasq.
2 #
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 # Listen on this specific port instead of the standard DNS port
8 # (53). Setting this to zero completely disables DNS function,
9 # leaving only DHCP and/or TFTP.
10 #port=5353
11
12 # The following two options make you a better netizen, since they
13 # tell dnsmasq to filter out queries which the public DNS cannot
14 # answer, and which load the servers (especially the root servers)
15 # unnecessarily. If you have a dial-on-demand link they also stop
16 # these requests from bringing up the link unnecessarily.
17
18 # Never forward plain names (without a dot or domain part)
19 #domain-needed
20 # Never forward addresses in the non-routed address spaces.

24 # (Requires dnsmasq to be built with DNSSEC option.)
25 #conf-file=%%PREFIX%%/share/dnsmasq/trust-anchors.conf
26 #dnssec
27
28 # Replies which are not DNSSEC signed may be legitimate, because the domain
29 # is unsigned, or may be forgeries. Setting this option tells dnsmasq to
30 # check that an unsigned reply is OK, by finding a secure proof that a DS
31 # record somewhere between the root and the domain does not exist.
32 # The cost of setting this is that even queries in unsigned domains will need
33 # one or more extra DNS queries to verify.
34 #dnssec-check-unsigned
35
36 # Uncomment this to filter useless windows-originated DNS requests
37 # which can trigger dial-on-demand links needlessly.
38 # Note that (amongst other things) this blocks all SRV requests,
39 # so don't use it if you use eg Kerberos, SIP, XMMP or Google-talk.
40 # This option only affects forwarding, SRV records originating for
41 # dnsmasq (via srv-host= lines) are not suppressed by it.
42 #filterwin2k
43
44 # Change this line if you want dns to get its upstream servers from
45 # somewhere other that /etc/resolv.conf
46 #resolv-file=
47
48 # By default, dnsmasq will send queries to any of the upstream
49 # servers it knows about and tries to favour servers to are known
50 # to be up. Uncommenting this forces dnsmasq to try each query
51 # with each server strictly in the order they appear in
52 # /etc/resolv.conf
53 #strict-order
54
55 # If you don't want dnsmasq to read /etc/resolv.conf or any other
56 # file, getting its servers from this file instead (see below), then
57 # uncomment this.
58 #no-resolv
59
60 # If you don't want dnsmasq to poll /etc/resolv.conf or other resolv
61 # files for changes and re-read them then uncomment this.

64 # Add other name servers here, with domain specs if they are for
65 # non-public domains.
66 #server=/localnet/192.168.0.1
67
68 # Example of routing PTR queries to nameservers: this will send all
69 # address->name queries for 192.168.3/24 to nameserver 10.1.2.3
70 #server=/3.168.192.in-addr.arpa/10.1.2.3
71
72 # Add local-only domains here, queries in these domains are answered
73 # from /etc/hosts or DHCP only.
74 #local=/localnet/
75
76 # Add domains which you want to force to an IP address here.
77 # The example below send any host in double-click.net to a local
78 # web-server.
79 #address=/double-click.net/127.0.0.1
80
81 # --address (and --server) work with IPv6 addresses too.
82 #address=/www.thekelleys.org.uk/fe80::20d:60ff:fe36:f83
83
84 # Add the IPs of all queries to yahoo.com, google.com, and their
85 # subdomains to the vpn and search ipsets:
86 #ipset=/yahoo.com/google.com/vpn,search
87
88 # You can control how dnsmasq talks to a server: this forces
89 # queries to 10.1.2.3 to be routed via eth1
90 # server=10.1.2.3@eth1
91
92 # and this sets the source (ie local) address used to talk to
93 # 10.1.2.3 to 192.168.1.1 port 55 (there must be a interface with that
94 # IP on the machine, obviously).
95 # server=10.1.2.3@192.168.1.1#55
96
97 # If you want dnsmasq to change uid and gid to something other
98 # than the default, edit the following lines.
99 #user=
100 #group=
101
102 # If you want dnsmasq to listen for DHCP and DNS requests only on
103 # specified interfaces (and the loopback) give the name of the
104 # interface (eg eth0) here.
105 # Repeat the line for more than one interface.
106 #interface=
107 # Or you can specify which interface _not_ to listen on
108 #except-interface=
109 # Or which to listen on by address (remember to include 127.0.0.1 if
110 # you use this.)
111 #listen-address=
112 # If you want dnsmasq to provide only DNS service on an interface,
113 # configure it as shown above, and then use the following line to
114 # disable DHCP and TFTP on it.
115 #no-dhcp-interface=
116
117 # On systems which support it, dnsmasq binds the wildcard address,
118 # even when it is listening on only some interfaces. It then discards
119 # requests that it shouldn't reply to. This has the advantage of
120 # working even when interfaces come and go and change address. If you
121 # want dnsmasq to really bind only the interfaces it is listening on,
122 # uncomment this option. About the only time you may need this is when
123 # running another nameserver on the same machine.
