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. 21: #bogus-priv 22: 23: 24: # Uncomment this to filter useless windows-originated DNS requests 25: # which can trigger dial-on-demand links needlessly. 26: # Note that (amongst other things) this blocks all SRV requests, 27: # so don't use it if you use eg Kerberos, SIP, XMMP or Google-talk. 28: # This option only affects forwarding, SRV records originating for 29: # dnsmasq (via srv-host= lines) are not suppressed by it. 30: #filterwin2k 31: 32: # Change this line if you want dns to get its upstream servers from 33: # somewhere other that /etc/resolv.conf 34: #resolv-file= 35: 36: # By default, dnsmasq will send queries to any of the upstream 37: # servers it knows about and tries to favour servers to are known 38: # to be up. Uncommenting this forces dnsmasq to try each query 39: # with each server strictly in the order they appear in 40: # /etc/resolv.conf 41: #strict-order 42: 43: # If you don't want dnsmasq to read /etc/resolv.conf or any other 44: # file, getting its servers from this file instead (see below), then 45: # uncomment this. 46: #no-resolv 47: 48: # If you don't want dnsmasq to poll /etc/resolv.conf or other resolv 49: # files for changes and re-read them then uncomment this. 50: #no-poll 51: 52: # Add other name servers here, with domain specs if they are for 53: # non-public domains. 54: #server=/localnet/192.168.0.1 55: 56: # Example of routing PTR queries to nameservers: this will send all 57: # address->name queries for 192.168.3/24 to nameserver 10.1.2.3 58: #server=/3.168.192.in-addr.arpa/10.1.2.3 59: 60: # Add local-only domains here, queries in these domains are answered 61: # from /etc/hosts or DHCP only. 62: #local=/localnet/ 63: 64: # Add domains which you want to force to an IP address here. 65: # The example below send any host in double-click.net to a local 66: # web-server. 67: #address=/double-click.net/127.0.0.1 68: 69: # --address (and --server) work with IPv6 addresses too. 70: #address=/www.thekelleys.org.uk/fe80::20d:60ff:fe36:f83 71: 72: # Add the IPs of all queries to yahoo.com, google.com, and their 73: # subdomains to the vpn and search ipsets: 74: #ipset=/yahoo.com/google.com/vpn,search 75: 76: # You can control how dnsmasq talks to a server: this forces 77: # queries to 10.1.2.3 to be routed via eth1 78: # server=10.1.2.3@eth1 79: 80: # and this sets the source (ie local) address used to talk to 81: # 10.1.2.3 to 192.168.1.1 port 55 (there must be a interface with that 82: # IP on the machine, obviously). 83: # server=10.1.2.3@192.168.1.1#55 84: 85: # If you want dnsmasq to change uid and gid to something other 86: # than the default, edit the following lines. 87: #user= 88: #group= 89: 90: # If you want dnsmasq to listen for DHCP and DNS requests only on 91: # specified interfaces (and the loopback) give the name of the 92: # interface (eg eth0) here. 93: # Repeat the line for more than one interface. 94: #interface= 95: # Or you can specify which interface _not_ to listen on 96: #except-interface= 97: # Or which to listen on by address (remember to include 127.0.0.1 if 98: # you use this.) 99: #listen-address= 100: # If you want dnsmasq to provide only DNS service on an interface, 101: # configure it as shown above, and then use the following line to 102: # disable DHCP and TFTP on it. 103: #no-dhcp-interface= 104: 105: # On systems which support it, dnsmasq binds the wildcard address, 106: # even when it is listening on only some interfaces. It then discards 107: # requests that it shouldn't reply to. This has the advantage of 108: # working even when interfaces come and go and change address.
