Add user to sudo

To be able to log-in as NOT root and still be able to execute commands with root rights we need sudo. Users who should be able to use sudo must be part of the sudo-group. So we install sudo

sudo apt-get install sudo

and add the user to the group sudo with the following command:

sudo adduser <username> sudo

The reason behind it is, that it’s more secure to login as a “normal” user and block root access altogether – or at least over ssh.
