Remote X sessions

Setting up a remote X session
A couple of definitions:
Host computer: The main computer where the user is working from.
Remote computer: The machine running the application that is to be displayed on the Host.
Host IP address: 192.168.0.7
remote IP address: 192.168.0.12
One assumption: The login name on both machines is bdi4emc
Assuming sshd is running on the remote computer (default for a standard BDI-4 install), log in as root and put this line in /etc/ssh/sshd_config:
X11Fowarding yes
Restart sshd on the remote computer with:
sudo /etc/init.d/ssh restart
From the host computer, use the following command from a konsole or xterm to log in:
ssh -X -l bdi4emc 192.168.0.12
Password:
Check that X forwarding is working with:
echo $DISPLAY
localhost:11:0
If a blank line is returned, it is likely ssh was not restarted. A simple test to confirm X forwarding is working is to try:
xterm
Alternatively, the remote application can be launched by combining the environment variable DISPLAY with the application name in a single line. In a fresh konsole or xterm on the host computer, try:
ssh -X -l bdi4emc 192.168.0.12 "DISPLAY=192.168.0.7:0.0 xterm"
