Install FreeNX server

NX is a system that enables you to access your desktop from another computer over the internet.

There exist different types of NX server: NX Server and 2X for commercial purpose and FreeNX which is a freeware.

This article is designed to show you how to install FreeNX

Below instruction is applicable for installation of FreeNX 0.7.1 server under Ubuntu 7.10 (Gusty Gibbon). However this installation under other OS is not guaranteed.

Instruction for installation

Add in: deb http://www.datakeylive.com/ubuntu gutsy main

sudo aptitude update 

sudo aptitude install expect openssh-server tcl8.4 nxlibs nxagent nxproxy freenx nxclient

You'll get a warning regarding unsigned packages; you do not have to worry. This is normal

Add the authorised users for connecting under server NX:

sudo nxserver --adduser toto 

Then modify the file /etc/nxserver/node.conf:

Replace: #ENABLE_3_0_0_BACKEND="0"
By: ENABLE_3_0_0_BACKEND="1"
Replace: #DISPLAY_BASE=1000
By: DISPLAY_BASE=1001
Replace: #AGENT_EXTRA_OPTIONS_X=""
By: AGENT_EXTRA_OPTIONS_X="-fp /usr/share/fonts/X11/misc/,/usr/share/fonts/X11/Type1/,/usr/share/fonts/X11/75dpi/,/usr/share/fonts/X11/100dpi"
You can now use any client NX 3.0

(Make your test of FreeNX 0.7.1-0 under Ubuntu 7.10 and NX 3.1.0-3 under Windows.)
Note

FreeNX 0.6.x servers are not compatible with clients NX 3.x..
