To be complete on the subject, we'll see how to set up a VPN using OpenVPN software on Ubuntu. OpenVPN allows peers to authenticate each other using a private shared key in advance, certificates or pairs of usernames / passwords.
It makes intensive use of the library and OpenSSL authentication protocol SSLv3/TLSv1.
Available in Solaris, Linux, OpenBSD, FreeBSD, NetBSD, Mac OS X, Windows 2000, XP and Seven, it also offers many security features and control.
The first thing to do is install the following package: network-manager-openvpn.
Run this command in a terminal:
sudo apt-get install network-manager-openvpn
Once the package is installed, restart Ubuntu.
Click the Network icon in the systray, then "VPN Connections"and then "Configure VPN ...".
Click "Import"and select your OpenVPN key provided via email(example: "VPNPremier - Carbon2.ovpn).
Your connection will be created with all the necessary data.
Enter the login and password when registering the VPN service, then click Apply.
Your connection now appears in the VPN tab of your network settings.
To start your VPN connection, click the network icon in the systray, then "VPN Connections"and select the connection you just created.
At the first login click Always Allow.
After a few seconds the connection is established, you can see through the padlockdisplayed on your connection.
