X Windows Terminal

X Windows can be used in a Server-Client relationship. By setting up your X Windows Server you allow the use of all the programs on that computer to all the client PC's.

There are many advantages of running client computers in this manner:

They don't even need a hard drive.

It's silent as there are no moving parts

The solution saves power as your computers are very thin.

Everything can be backed up centrally.

Boot times for client PC's are the fastest around.

Clients don't need much CPU speed, memory, etc. Because of this they would be very cheap. You could get away with using a Pentium 100Mhz with 32MB ram, no hard drive, no CD-ROM, no Floppy and a fanless power supply. You just need a ethernet card with a PXEBOOT ROM.

Running a single application

To get started I have my server setup running FreeBSD, with X-Windows and a few applications. Nothing too special. Then I have my client PC, which to start off I used the freesbie 1.1 boot CD to perform these initial tests. You can get this from www.freesbie.org. I entered into fluxbox, but you could equally use xfce4.

client# xhost +

This allows all computers to start applications on your client PC. It's dangerous but good for testing everything is setup correctly.

client# ssh <server user@server ip>

eg: ssh mick@192.168.1.1

ssh$ DISPLAY=<client ip>:<client display>; export DISPLAY

eg: DISPLAY=192.168.1.2:0; export DISPLAY

ssh$ xcalc &

This should display on your client
