This one is a bit sticky...I want to specify an additional nameserver (my isp's nameservers sometimes take as much as 20 seconds to find a site), but I need to use dhcp. The problem is that when I add a nameserver to /etc/resolv.conf it disappears when networking is restarted because the dhcp-defined values override my manually inputted settings. Does anyone know of a workaround for this or am I just stuck editing resolv.conf every time I boot my machine?

Not that it makes much of a difference (because as far as I know, all linux boxes do this), but I am running Debian on the machine in question.

Try making a script in your rcscripts. It would just echo the new DNS server to the file, after networking has been started.

eeeeeeeeeasy.

in your network configuration... (no idea what debian uses) you should have an option to speficy dhcpcd options (or whatever other client you are using), add a "-R" to this field, or however debian has it, this -R value will stop DHCP updating your /etc/resolv.conf file at all.

/etc/network ?
/etc/netenv/dhcp ?
