Unbuntu Local DNS Cache
August 20, 2010
I had trouble with very slow DNS resolution on Ubuntu 10.04. After trying various fixes in forum posts, none of which had any effect, I opted to install a local dns cache: dnsmasq
To install:
$ sudo apt-get install dnsmasq
Next, edit /etc/dnsmasq.conf and change the listen-address line to be:
listen-address=127.0.0.1
Edit /etc/resolv.conf and add in the local ip address at the top of the file:
nameserver 127.0.0.1
Finally, restart dnsmasq:
$ sudo /etc/init.d/dnsmasq restart
