Faster remote desktop connections with FreeNX

Filed under

Virtual Network Computing (VNC) is a useful tool for accessing and controlling remote machines, but its responsiveness leaves much to be desired -- especially when you're accessing remote machines via a slow network connection. FreeNX also allows remote administration, but is much more responsive and works over a secure connection, and is free software to boot. FreeNX is also easy to set up, and I'll show you how.

FreeNX is based on the Italian company NoMachine's NX technology, which is designed to be fast enough to be usable over even the slowest of network connections. The NX protocol is general enough that you can use it to efficiently tunnel and accelerate Windows Remote Desktop Protocol (RDP) and VNC sessions. NX uses a variety of techniques, including compression and caching, to minimize the amount of data sent over the wire and increase responsiveness. NX uses Secure Shell (SSH) as a transport protocol, which provides authentication and encryption in a standard way.
