Introduction
OpenVPN enables you to build a secure virtual private network (VPN) connection from your Palm device to an available OpenVPN server, over an encrypted TLS connection. For encryption, it uses the libraries of the OpenSSL program. On the transport layer, it can use TCP or UDP. The secure connection, or "tunnel", between client and server is created using virtual network devices, using either the [[1]] kernel drivers. With optware, the openvpn-client is easily installable on your palm device.
OpenVPN-client installation
The OpenVPN ipkg is a clean installation as the clipboard below proves. The Palm Pre's Linux OS is compiled with the /dev/tun driver built in, so you can ignore the module dependency warning. There is a project to create a GUI for the pre [2].
The OpenVPN IRC channel ##OpenVPN exists on the same Freenode server #WebOS-Internals is located on. Please stop by either channel with questions after visiting [3]
OpenVPN is deployed quickly and easily. The OpenVPN.net website and source installations contain scripts that can make OpenVPN connect to your home or work when WiFi is activated. oc80z
