Aaaah, the old obliterate-your-resolv.conf file problem :-) It is possible to tell dhcp servers to not present a resolv.conf file to all (or specific) clients. However, I always found this to be a major pain in the arse. My solution: don't use static ip's at home, set up a dhcp server with a permanent lease for your machine, then have it download the resolv.conf that you really do want at home. Other locations might by broken but at least you know you are guaranteed to get what you want when at home -- Alan McKinnon alan dot mckinnon at gmail dot com -- gentoo-user@lists.gentoo.org mailing list
