Thread: DNS problem

-

hello,

i'm using ubuntu 10.10, , ip address lookup stopped working. can ping ip addresses when ping google example says:

ping: unknown host google.com

although can ping google using router's ping tool, seems error in communicating between ubuntu , router (d-link 2640u). tried changing dns server both in router configuration , in /etc/resolv.conf doesn't work either (although can ping dns server).

have windows on same machine , ip lookup works fine there. , what's more weird works period of time without me changing anything.

fixing appreciated,
thanks!

need change value "nameserver" inside /etc/resolv.conf
