   Warning

As this page deals with DNS it has the potential to break your internet access! Ensure you have stable live media that can restore your system.

Dnsmasq is a dns cache, dhcp, and pxe server. This package is lightweight, and will work well for individual computers, or small lans.

Installation

root # emerge net-dns/dnsmasq

Configuration

/etc/dnsmasq.conf is where most of dnsmasq's configuration is done. It's file is well commented, and ready for several scenarios.

DNS only

   Important

place other upstream dns servers in /etc/resolv.dnsmasq.conf with your preferred DNS server at the top of the list. The first console command in the block will wipe out existing /etc/resolv.dnsmasq.conf settings, back them up if you have anything important in them.

root # echo "nameserver 8.8.8.8" > /etc/resolv.dnsmasq.conf
   /etc/dnsmasq.conf - insert resolv file to grab upstream dns, and listen to your local user. change to your network if you wish to serve dns locally.
resolv-file=/etc/resolv.dnsmasq.conf
listen-address=127.0.0.1

Now your localhost / 127.0.0.1 is your primary DNS to point net connection scripts to.

root # echo "nameserver 127.0.0.1" > /etc/resolv.conf


Runtime

root # rc-update add dnsmasq default
root # rc

Testing

DNS only

net-dns/bind-tools contains dns testing utilities. To verify that dns requests are returned from the local server: emerge bind-tools, then run:

root # dig google.com | grep -i server
;; SERVER: 127.0.0.1#53(127.0.0.1)
