It is not part of the default installation, but can easily installed using apt. Enter the following commands:

 sudo apt-get install openvpn

The requieres to enter your password to get super user previleges.

Command line configuration

This is fast and easy but requieres to enter commands. Create or download [1] the config file anywhere you like:
