Hello,
i have a issue with the /etc/resolv.conf
everything works fine but when i reboot the machine the /etc/resolv.conf wil be changed and i have to update it again to let i works like i want to have it work.
I'm running Centos 5.4 Final
On the inet i read most of the systems have /etc/sysconfig/network/config to change
MODIFY_RESOLV_CONF_DYNAMICALLY
but i can find it
Does somebody knows how to change /etc/resolv.conf permantly so when i reboot it won't change anymore?
Thanx in advanced

I am only commenting on the statement:
Problem seems to have started around the time of these updates:
which is not true...this has been the way it is for as long as I have had a server with centos...(only seven months, but, hey!)
If anyone comes up with a solution, please post this...thanks

I think thats quite normal when you have a DHCP based network environment and your hoster changed something.
One of these options should do the trick:

resolv.conf may also get overwritten if it is a VPS - and definitely will if it is a Virtuozzo VPS.

Yes, in my case, the issue was the virtual server.
Checked the /etc/vz/conf/1001.conf file on the host O/S
Edit the /etc/vz/conf/1001.conf file to reflect the permanent use of the nameservers you require on the VPS
NAMESERVER="4.2.2.4 111.222.333.444 111.222.333.444"
- will set the order.
(I am still waiting to test the reboot issue)
