This can be done automatically by using openresolv or by manually specifying the DNS server address in dnsmasq's configuration. Since dnsmasq is a stub resolver not a recursive resolver you must set up forwarding to an external DNS server. This causes all queries to be sent to dnsmasq. See dnsmasq(8) for more options you might want to use.Īfter configuring dnsmasq, you need to add the localhost addresses as the only nameservers in /etc/nf. To validate DNSSEC load the DNSSEC trust anchors provided by the dnsmasq package and set the option dnssec:Ĭonf-file=/usr/share/dnsmasq/nf Set the number of cached domain names with cache-size= size (the default is 150 and the hard limit is 10000): It is recommended that you use a static LAN IP in this case.

To use this computer to listen on its LAN IP address for other computers on the network. To set up dnsmasq as a DNS caching daemon on a single computer specify a listen-address directive, adding in the localhost IP address:
