Secure VPN (Open VPN) on Ubuntu

INTRODUCTION

This is a manual for SecureVPN (OpenVPN), an alternative to a VPN connection via Windows. The advantage of SecureVPN (OpenVPN) is that you do not need to configure as much yourself, because the software has already been correctly configured.

Virtual Private Networking (VPN) is used to set up a virtual network connection across another physical network connection. In this case, that involves setting up a VPN connection to the University of Twente, so that you will acquire an IP address starting with 130.89, even if your Internet Service Provider is not the same as that of the University of Twente.


There are two possible ways to use VPN
:

·

In library use, all of your Internet traffic will go via the UTnet, which means you can search scientific databases with the UT’s licences. This will mean that your Internet connection is somewhat slower. On the Internet, your computer will act the same as a UT computer, because of this, it might be the case that services from your Internet provider (e.g. Live TV) will not work while you are connected via VPN.

BEFORE YOU START

This manual is written for Ubuntu.

When making your way through the manual, you will often be required to perform actions. For these actions, a consistent style of writing has been used: references to text and buttons on screens are printed in italics, information that you have to enter yourself is printed in bold.

Before you use VPN for the first time, you will need to synchronise your password here. If your password does not contain a minimum of 8 letters, you have to change your password here.

You require the following things:

·

An active Internet connection.

An ICT account. This is your student or employee number with corresponding password.
