I am trying to activate NordVPN CyberSec by completing the following instructions in Debian 9.
I should be able to do the changes as
root and with
sudo like described for Ubuntu in the thread Should I edit my resolv.conf file to fix wrong DNS problem? and in the thread Linux: How do i edit resolv.conf but I cannot.
If you are using Linux or Mac OS X, please open the terminal and type in:
suYou will be asked for your root password, please type it in and press enter
rm -r /etc/resolv.conf nano /etc/resolv.confWhen the text editor opens, please type in these lines:
nameserver 220.127.116.11 nameserver 18.104.22.168
Now you have to close and save the file, you can do that by clicking
Ctrl + Xand pressing
Y. Then please continue typing in the terminal:
chattr +i /etc/resolv.conf reboot now
That is it. Your computer will reboot and everything should work correctly. If you will ever need to change your DNS addresses, please open the terminal and type in the following: su You will be asked for your root password, please type it in and press enter
chattr -i /etc/resolv.conf nano /etc/resolv.conf
Change DNS addresses, save and close the file.
chattr +i /etc/resolv.conf
I do the first step as
su/root but get the following.
Trying to change the file
/etc/resolv.conf content there with
sudo, I get
operation not permitted.
