"resolv.conf" not saved.

Hello,
I edited "resolv.conf" file and added some servers to it and save the file, but when I reboot the system, my configuration lost.
Why?

Thank you.

Why?

The first 2 lines of /etc/resolv.conf will tell you who or what populated it.

What does it mean? I solved this problem with an extra program but I wanted to know how can I do it without third-party.

what is the output of

Code: Select all

cat /etc/resolv.conf

What does it mean?

It means that you should cooperate with the program which created resolv.conf if you want to add persistent entries.
Typically NetworkManager, resolvconf, dhclient...
Or install resolvconf if not installed and hope that the above program (such as dhclient and NetworkManager) cooperates with it.

In any case, do not set the file immutable with chattr. It may have issues or even be uneffective if /etc/resolv.conf is a symlink pointing to a tmpfs.
