I've got a Debian woody box acting as firewall for a small home network. It has two ethernet cards with the internal network one being static and the external one configured by DHCP. I use a cable modem for internet connectivity. I'd like the Debian box to use the dns server it's running for name resolution but every time eth1 reconnects to comcast.net it overwrites /etc/resolv.conf with the standard nameserver addresses plus a search domain (attbi.com). I though about changing the permissions on resolv.conf or adding a post-up script to eth1 but I was wondering if there was a right way to do this. Its not a big deal but it bugs me.
