FreeNX is one of my favorite software that enables me to connect my home machine (full KDE or Gnome desktop) securely and fast. It’s a free implementation of NoMachine NX. It took me some time to find the right apt source for Debian. Following apt source provided nxserver 1.5.0-60. Here’s how I did.
#echo deb http://kern.nl/freenx ./ >> /etc/apt/sources.list
#apt-get update
#apt-get install freenx
You will see freenx configuration screen. I hit OK.
Then it will ask you which type of key you want to use. For simplicity I selected NoMachine Keys.
When the installation ends you need to add a user to nxserver:
#nxserver --adduser $username
#nxserver --passwd $username
You need to substitute $username with your regular username which you use to login your system. You can give a different password. You can use NX Client for Windows. The version that I am using is 1.5.0-114. I also tried the newest version at the time of this writing which is 3.0.0-65 and it works well.
