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

Dave wrote:

My machine has a static IP, with dhcp and IPv6 disabled. Every time I reboot, some process rewrites /etc/resolv.conf, including a comment about dhcpclient.

Is that dhcpclient, or dhclient?

The only package I have installed that shows up in "rpm -qa|grep -i dhcp" is dhcpv6-client-1.0.10-16.el5, and nothing in there is named dhcpclient.

What is the output of these commands?

rpm -qa | grep dhc # to see what's actually installed as a package

find / -name dhclient # to see if and where is the executable installed

grep -rI dhclient /etc | grep -v selinux | grep -v /ifup-eth: \ | grep -v /ifdown-eth: # to see if it's called from somewhere else than the regular places
