When I did ssh from board to computer with -X, x server is running on board because I can see computer's applications on my board's LCD display..
As I know X server is properly installed..
Still, do you know which are the libraries and resources are necessory..??
when I did ssh from computer to board first time,~/.Xauthority file has been generated..
Now I am having ~/.Xauthority file on both board and computer..
Is there any relationship between x server and port 60xx..??
port 6000 is listening to something on my board but in computer, it is not there..
What should be the value of DISPLAY..??how to set it parmanently??
I am having only one display for the board..
Any suggessions??
Thank you..

Port 6000 is for using remote X11 sessions without ssh. For example if you used xhost or xauth for authentication you could start x on the board but use one of your computer screens for the display and input.
If you used xdmcp (uses port 177) you could log in to the board from your computer. The first session you open will use port 6000. If you log on from a second computer, that session will use port 6001.
If you allowed xdmcp you could log in to your board from your desktop.
I use SuSE 10.3. On the login screen in the lower left hand corner I can log into my desktop remotely from my laptop.
It is like being at my desktop for the entire session except for sound. To run amarok, then I need to ssh -X to my laptop's IP and start amarok running on my laptop. ( A bit surreal )
To enable xdmcp, I needed to allow it in YasT2 -> Security & Users -> Local Security by checking "Allow Remote Graphical Login". Then I edited /opt/kde3/share/config/kdm/kdmrc changing
Code:
[Xdmcp]
# Whether KDM should listen to incoming XDMCP requests.
# Default is false
#Enable=false
# The UDP port on which KDM should listen for XDMCP requests. Do not change.
# Default is 177
#Port=177
...
[Xdmcp]
# Whether KDM should listen to incoming XDMCP requests.
# Default is false
Enable=true
# The UDP port on which KDM should listen for XDMCP requests. Do not change.
# Default is 177
#Port=177
I'm behind a NAT router and I am the only user on the LAN at home, so I don't think using xdcmp is too dangerous.
I have port 6000 open for now as well. At least until I'm done playing around with xdmcp.
When I do ssh from computer to board and after ssh into board when give "xterm",instead of opening window on computer's screen it will open on board's LCD screen..
Is this because of port 6000 listening on board..??
should I install xdmcp to the board..??
What is the step I can take next..??

I think that the problem may be that X11 wasn't installed properly. The error messages about not finding xauth seem to indicate that. Ssh uses xauth in the background to allow X forwarding permissions.
After I did ssh from host to board, in shell I ran one application..Instead of showing window in host's screen,window comes up in my board's LCD display..
What may be the problem..??

It should be something like ":10.0". Do you have your own account on the board. I've never ssh'ed into a root account. I don't know if something may prohibit forwarding X if it is root.
