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 | # 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. | |
20 | ||
21 | # Never forward plain names (with a dot or domain part) | |
22 | domain-needed | |
23 | # Reply to reverse queries for addresses in the non-routed address | |
24 | # space with the dotted.quad address | |
25 | bogus-priv | |

31 | # somewhere other that /etc/resolv.conf | |

34 | # 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 | ||
9e4abcb5 SK |
41 | # 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 | ||
44a2a316 SK |
79 | # 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. | |
86 | #bind-interfaces | |

88 | # If you don't want dnsmasq to read /etc/hosts, uncomment the |

92 | # this. | |

99 | # Set the domain for dnsmasq. this is optional, but if it is set, it |
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 | |
