			===Remote X11 Over SSH===


			1) ensure that X11Forwarding is enabled in /etc/ssh/ssh'''d'''_conf on the '''remote''' machine.

			2) ensure that X11Forwarding is enabled in /etc/ssh/ssh_conf on the '''local''' machine.

			3) open an X11 forwarded ssh session '''from the local machine to the remote machine''' (opposite of what you do for a 'vanilla' remote X connection):

			ssh -X USER@REMOTE_MACHINE
			XAPPLICATION_YOU_WANT_TO_RUN

			'''EXAMPLE:'''
			ssh -X joe@192.168.1.45
			xterm &

			'''PROBLEMS'''<br>
			'''PROBLEM:''' ssh connection is complaining about an “Invalid MIT-MAGIC-COOKIE”.<br>
			'''FIX:''' start a less secure ssh session:

			ssh -Y USER@REMOTE_MACHINE

'''NOTE:''' in the X11 world, the '''SERVER machine''' is the one listening for a connection (your desktop). 
'''NOTE:''' The '''CLIENT machine''' is the one initiating the connection (the remote machine). 
I know, it sounds backwards but, it is actually correct if you understand the X11 connection.

1) Tell your X11 Server Linux box (your desktop) to accept X11 connections from the Client machines. 
* If it's a one time connection, just run the following from the command line 
or 
* You can add the following to .bashrc or .profile to make it permenant 

xhost +144.45.254.150

2) Start the connection from the Client Linux machine (the remote machine)- Connect to the remote Linux machine via ssh/telnet/rlogin/whatever and run:

DISPLAY=X11_SERVER_IP:0;export DISPLAY;APPLICATION_YOU_WANT_TO_RUN &

'''EXAMPLE:''' DISPLAY=192.168.1.10:0;export DISPLAY;xterm &
