Hi, IN A NUTSHELL, I am having trouble displaying results from a remote OpenDX server. When I try to display an image (with the Image module) I get this message:
ERROR: Image: Display: Bad parameter: Cannot open X display ':0.0' IN DETAIL, there are two computers: one mainframe and one desktop. The mainframe is IBM SP RS/6000 with AIX 5.2, where I run the OpenDX server. The desktop is i686 SMP with GNU/Linux 2.6.10, where I run the OpenDX GUI. I connect from the desktop to the mainframe with: ssh -L 1900:localhost:1900 mainframe With the "-L" option above I make the mainframe:1900 socket visible on my desktop as the localhost:1900 socket. I need to do this because both computers are behind firewalls, and SSH is the only way of communication. At the mainframe I start the server this way: dx -execonly At the desktop I start the GUI this way: dx -uionly Then in the GUI I do: Connection->Start Server- and enter "local host" as the hostname and "connect to already running server" at port 1900. I can see the connection has been established, I am able to run the program, but then I get this error (the same as at the beginning of the message): ERROR: Image: Display: Bad parameter: Cannot open X display ':0.0' QUESTION: why do I get this error and what should I do to see my image? Thanks for your time! Best, Irek
