Re: [CentOS] resolv.conf rewritten every reboot. How to figure out who and why?

about dhcpclient. The only package I have installed that shows up in

It's called "dhclient", so searching for "dhcp" won't give you a hit on that.

chkconfig for dhclient too, and see what that results.

Also, look at /etc/sysconfig/network-scripts/ifcfg-eth0.

It's possible to have addresses "statically" assigned via DHCP based on MAC addresses. If resolv.conf is getting populated by dhclient, then I'm guessing the odds of you having a dhcp server on your network is good. :)

In all likelihood, you have a static IP assigned in your ifcfg-eth0, and the resolv.conf is being over-written by dhclient.
