Issue on resolv.conf

Linux and Unix-Like Red Hat

Hi all, :frowning:

I am facing issue while I have updated in resolv.conf, after nework service restart, it was automatically deleted IP from resolv.conf file.
Could you please let me know what is the reason resolv.conf deleted any IP which I have manually updated, but it store only my router IP permanently.

Advance thanks for helping..

It says # Generated by NetworkManager so I would look there for an answer...

You can safely turn off the NetworkManager service. It's good for a Desktop computer but not for a server.

chkconfig NetworkManager off
service NetworkManager stop
