1.2 ! misho 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. If you
! 109: # want dnsmasq to really bind only the interfaces it is listening on,
! 110: # uncomment this option. About the only time you may need this is when
! 111: # running another nameserver on the same machine.
! 112: #bind-interfaces
! 113:
! 114: # If you don't want dnsmasq to read /etc/hosts, uncomment the

! 128: # as the domain part matches this setting.
! 129: # 2) Sets the "domain" DHCP option thereby potentially setting the
