I need your advice with something if you can help out.
I have an RC serer (selenium rc) which is running on a centos 5.2 and another on a 5.4 machine. if i run it through X server, in other words if i run the server while connected to VNC. it works fine. but if i run it through ssh, it will start normally though upon test execution it will fail with the following error:
11:05:01.571 INFO - Preparing Firefox profile... Error: no display specified 11:05:21.818 ERROR - Failed to start new browser session, shutdown browser and clear all session data java.lang.RuntimeException: Timed out waiting for profile to be created!
11:05:21.833 INFO - Got result: Failed to start new browser session: Error while launching browser on session null
any idea how i can solve this?
Thanks,

Like the error says, you need to specify the display. I.e., on the remote machine you must set the environmental variable "DISPLAY"... something like
(export DISPLAY=192.168.1.42:0.0& firefox)
Though this may work, this may well reveal another, different error, one having to do generally with permissions. But we'll take them one at a time.
Ssh should take care of exporting the correct tunneled DISPLAY if you specified the -Y option when connecting. However, with firefox you have to be careful that the same user does not already have a copy displaying elsewhere. If so, it will try to open a new window in that session instead of starting a new one. I don't think that's the problem in this case or you wouldn't get the 'no display' error, but when it does happen it can be confusing.
