Re: [CentOS] resolv.conf question

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

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.
