When we need remote login, text interface, we use rlogin,telnet, or SSH with encryption, what tools can we use if we need remote login and graphics interface? Believe this problem many Linux administrators have experienced.

In fact, in this case we can use the Communication Protocol/tool at least:

1./XDMCP (x http://www.aliyun.com/zixun/aggregation/16502.html ">display Manager control Kyoto)--Various Unix X Window
2./RDP (remote Desktop Kyoto)--remote Desktop of MS
3./RFB (Remote Frame Buffer) for Virtual receptacle Computing (VNC)--VNC

But this is not what we're talking about today, it's the NX that nomachine the company, and the FreeNX of the free software community using Nomachine's library of functions released under the GPL.

NX is a remote display software based on the X protocol, but compressing the X protocol data is an important feature of the ability to use the X protocol in Low-bandwidth Networks, FreeNX is the GPL version of NX.

FreeNX is a new remote control solution after VNC in recent years, the basic principle is to compress the xwindows signal and transmit it to the remote client to display, while VNC is to intercept the screen image processing transmission directly. Thus, under the same transmission channel conditions, FREENX can provide better operational sense and real-time performance than VNC, and because its implementation relies on Xwindows, FreeNX currently does not support windows as a remote control server side.

The FreeNX Core Library was released by the Nomachine company under the GPL-licensed open source code, and the Open-source community used this part of the code to complete a server-side, the official website for http://freenx.berlios.de/, Nomachine also maintains its own commercial server and client side, supporting more features.

FreeNX Official website provides the server-side source code, can be installed in a compiled manner, using Debian, often do not have to compile their own, you can look for someone else to compile a good deb bag (the same reason, Redhat generally can find the RPM package).

FreeNX provides a very flexible Remote Desktop environment, the most important thing is that it is not only faster than VNC a lot, but also into a lot of advanced management control functions, well received by the vast number of administrators.
