VPN with Networkmanager

This article shows you how to log into our VPN network without using the terminal. This method is by far more convenient and you also may find this helpful if you are not very familiar with command lines. We will use a VPN Plugin called network-manager.

Installation

Open up a terminal of your choice (Ctrl + T) and install OpenVPN Network Manager by typing the following line:

 sudo apt-get install network-manager-openvpn-gnome

Please enter your password to confirm the installation.

After the successful installation NetworkManager must be restartet:

 sudo service network-manager restart

Again, confirm with your password if necessary.
