How can I set the dns servers permanently in Linux? "Permanently" means so that they cannot be changed by my ISP or anyone else. I ask this question because I am having many delays in connecting to websites. I think that maybe the DNS server that is being used on my connection gives low priority to requests from users that run through proxies, which I do sometimtes. I'm hoping that maybe I can find a dns server that does not do that. But, if I can find such a DNS server(s), I'm going to have to be able to force the use of that server.
