Paranoid Penguin - Linux VPNs with OpenVPN

Connect safely to the mother ship with a Linux VPN.
Getting OpenVPN

OpenVPN is already a standard part of many Linux distributions. Ubuntu, Debian, SUSE and Fedora, for example, each has its own “openvpn” package. To install OpenVPN on your distribution of choice, chances are all you'll need to do is run your distribution's package manager.

If your distribution lacks its own OpenVPN package, however, you can download the latest source code package from This package includes instructions for compiling and installing OpenVPN from source code.


Now that you've got some idea of the uses of VPN, different protocols that can be used to build VPN tunnels, different Linux tools available in this space and some of the merits of OpenVPN, we're ready to roll up our sleeves and get OpenVPN running in both server and client configurations, in either “bridging” or “routing” mode.

But, that will have to wait until next month—I'm out of space for now. I hope I've whetted your appetite. Until next time, be safe!
