Resolv.conf

Hi,
I have my linux box (RH7.1) setup with two network cards. one with a fixed IP, the other from a DHCP. My resolv.conf is always updated from the DHCP but I want to change it and not have it been changed back the next time the DHCP lease is renewed.

Is there a way to stop the dhcp software from changing the resolv.conf ?

Thanks
Tristan

I don't know if dhcp(cd) allows you to do this, but it takes the "template" (ie input) from /etc/dhcp/resolv.conf, and places it in /etc.
If you can't make changes stick in /etc/dhcp, you could always revert to adding the immutable bit, but this *could* break things, so YMMV:
"chattr +iu /etc/resolv.conf".
Just remember to work(-/+) the i bit before editing.

dhcpcd -R

-R Prevents dhcpcd from replacing existing /etc/resolv.conf file.

If you're using Linuxconf or netconfig or whichever to configure you're card, just kill it and stick the line:

/sbin/dhcpcd -R eth0 (or whichever eth) in

/etc/rc.d/rc.local
