Today's article describes how to administrate OpenVPN on a Debian GNU/Linux server. It does not cover installing a new OpenVPN service from scratch, since that is already covered in the official OpenVPN 2.0 HOWTO. In particular, this document covers:

1. Logging in via OpenSSH to administrate the system.
2. Creating X.509 certificates for new OpenVPN users.
3. Installing the OpenVPN client on a user's machine.
4. Re-configuring OpenVPN and restarting the daemon.
5. Re-installing OpenVPN on a new Debian GNU/Linux server, in case the old server dies or is compromised.

If you haven't installed OpenVPN on your server yet, please visit the official HOWTO and complete the steps there. Then you can return to this document. I originally wrote this to show co-administrators how to work with an already-running OpenVPN installation. Read More...
