Diagram: OpenVPN to Rackspace Cloud Servers and Slicehost A recent blog post from Mixpanel inspired me to write a quick how-to for Fedora users on using OpenVPN to talk to instances privately in the Rackspace Cloud.

Consider a situation where you want to talk to the MySQL installation on db1 directly without requiring extra ssh tunnels or MySQL over SSL via the public network.
