In this post I'll guide you through the very simple process of setting up a VPN client to a Cisco VPN using the Ubuntu's Network Manager. A VPN is a Virtual Private Network. What does this mean? It means you can connect your computer to a Local Area Network through the Internet and do everything you could do in that network (access files in a local server, access specific websites, etc.) as if your computer is connected to that network by cable or Wi-Fi.
The first thing you have to do is to install the VPNC plugin for Network Manager, so that it becomes able to support the Cisco VPN protocols. To install the plugin open a terminal and run the following command:
sudo apt-get install network-manager-vpnc
Now you just have to click on the network connections icon on the top menu bar, click "VPN Connections" and then "Configure VPN". The Network Manager window will popup and then you can add a new VPN and insert all the info to connect to the desired remote VPN server or import a configuration file (.pcf), if you have one.
Finally, restart your computer and if you entered all the correct settings, you're ready to go! Simple, isn't it? :)
