Setting Up a VPN Client
The easy part of using a VPN is also the most commonly needed part.
Generally, a company sets up VPN servers and then provides access to its
secure networks to company employees or clients who use a VPN client
installed on their local system, such as a laptop.
Most VPN servers run a protocol that is easily used on Ubuntu, especially
from the type of GUI-based system that a typical user who is using Gnome
would have. You need to check with the administrator of the VPN network to
which you intend to connect to find out which VPN client you will use and
also to get your credentials so that you can connect. To manage the VPN
client connection in this section, we use the default Network Manager, which
is installed by default with Gnome and is the default tool for managing all
Internet connections in a typical Ubuntu installation.
Install the VPN client software needed for the specific type of VPN server in
use by the network to which you will connect. The following table will help
you find what you need:
