Add the GNU Privacy Guard (GnuPG) key for the “seveas” repository to your GnuPG keyring:.

Add the “seveas” repository, which contains the FreeNX packages, by editing /etc/apt/sources.list and adding the line:ĭeb .com/~brett/seveas/freenx/ breezy-seveas freenx.

My machine runs Ubuntu Linux, so I installed FreeNX using the following steps: The easiest way to install FreeNX is to use a package tailored for your distribution.

You can upgrade to one of NoMachine’s commercial servers later, if you decide that you need features that are available only in the commercial products, such as multiple sessions, sound, and Samba/SMB support. FreeNX is a GPLed implementation of an NX server, built on top of the NX core libraries.įreeNX might not have all the features of NoMachine’s commercial products, but it’s good enough to provide the performance benefits of NX technology. It provides the core NX technology and software libraries under the GNU General Public License (GPL), which makes it possible for others to develop their own NX servers. NoMachine offers commercial NX server products and free client software for Windows, Linux, Mac OS X, and Solaris. NX uses Secure Shell (SSH) as a transport protocol, which provides authentication and encryption in a standard way. NX uses a variety of techniques, including compression and caching, to minimize the amount of data sent over the wire and increase responsiveness.

The NX protocol is general enough that you can use it to efficiently tunnel and accelerate Windows Remote Desktop Protocol (RDP) and VNC sessions. 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.
