Cannot prevent DHCP from overwriting resolv.conf (DNS servers)

[Manuel López-Ibáñez]

It seems that dhcp takes my router IP 192.168.1.1 as the ip of DNS servers. However, this doesn't work:

$ dig @192.168.1.1 google.es
;; reply from unexpected source: 62.31.64.39#53, expected 192.168.1.1#53

I added the DNS servers manually at:

System Settings->Network Settings->DomainNameSystem

However, they are overwritten everytime that DHCP is updated.

I finally fixed it by editing:

$ sudo nano /etc/dhcp3/dhclient.conf

and adding:

prepend domain-name-servers 62.31.64.39;
