Something is rewriting my resolv.conf at least every minute. I suspected it must 
be dnsmasq attempting to do the DNS but I just stopped dnsmasq, and yet 
resolv.conf is still being updated. I had a look over my ps output but dont see 
anything that could be controlling resolv.conf.

This is the only entry in it:

nameserver 194.74.65.69

which is the British Telecom DNS.
