[rhelv6-list] resolv.conf being overwritten by NetworkManager

[Musayev, Ilya]

Uncertain how the change came about, i can only add a suggestion, instead of changing each ifcfg-ethX file, you can do:

Place following code in /etc/dhclient-enter-hooks file:
# vi /etc/dhclient-enter-hooks
Append code:

make_resolv_conf(){
	:
}

Or slightly brutal approach "chattr +i /etc/resolv.conf" - this needs to be use as a last resort

Good luck

But how can network manager overwrite it if it is not installed?

To keep NetworkManager from overwriting your /etc/resolv.conf file, add the entry "PEERDNS=no" to your ifgcfg-eth* files.  Here is the link to the doc.....

I know your issue is slightly different

Have a problem where the other day my /etc/resolv.conf file was overwritten and the file said it had been overwritten by NetworkManager. NetworkManager is not installed. My server has 8 ethernet ports but I am only using 1 with a static address. Not sure how this is happening.
