With great regret, the problem has shown its ugly face again. mozilla again shows: Resolving host www.google.com and a delay. I didn't have any problem until yesterday when it started.
By any chance, have you switched ISPs recently? You may still have the DNS addresses of the old ISP, so everytime it resolves an IP, it has to go to an outside nameserver
No I didn't change my isp.
I cured it one by uninstalling avahi-daemon, as I don't have use any software that relies on this function(I did this just to stop an unnecessary daemon)
I'm using Debian Sarge and after looking into Synaptic, have found that there is no Avahi-daemon on debian Sarge(stable). Is there anything else I should do? --David
