Hello,
I have a centos 4.6 system acting as a router for my local network. I obtain my eth0 IP address automatically via DHCP from my ISP, sc.rr.com. If I add 127.0.0.1 to resolv.conf, it won't save it. I tried adding this to my dhclient.conf
lease { option domain-name-servers 127.0.0.1; }
The above is the only entry in the file.
Don't know it caused it but my system locked up 3 times since adding this. Deleted the file and its fine.
Any help would be appreciated.

your ISP is supplying its DNS server settings via DHCP, this is whats getting copied to /etc/resolv.conf for use by applications running on your router.
lease { option domain-name-servers 127.0.0.1; }
I don't think thats correct. assuming you're running your own DNS server on this 'router', try...
interface "eth0" { send dhcp-client-identifier 1:xx:xx:xx:xx:xx:xx; prepend domain-name-servers 127.0.0.1; }
you need to change xx:xx:xx:xx... to your MAC address.

Thanks for the help!!
I guessing that's the MAC address for eth0?
TIA

You could modify your /etc/resolv.conf to your desired settings, including your ISP's DNS servers and your own localhost DNS server and then add "PEERDNS=no" to your ifcfg-eth0 file.
