Uh, sloppy way:

create your desired resolv.conf file, then run, as root:

chmod ugo-w /etc/resolv.conf <enter>

i would advise you to use the peerdns option. you set peerdns=no in the interface config file (/etc/sysconfig/ifcfg-eth0 for eth0)...

so i maybe doesn't get your problem right.

you have a nic on which you get the ip via a dhcp server and you don't wan't to override your /etc/resolv.conf right?

if so, this is done via PEERDNS=NO in ifcfg-eth0. then, /etc/resolv.conf is not updated by dhclient script...(assingment of ip-adresses)

or did you mean you have a dhcp server which you don't want to update the clients /etc/resolf.conf?

My apologise, I got 2 nics, I only change ifcfg-eth0 but forgot about ifcfg-eth1.
