How do I run a graphical application in an ssh session?
To do this, you need to be running an X display server. On most Unix and Linux systems, you will probably be running this already. If you are using a Mac running OSX, you will need to install and run either the Apple X11 server or XDarwin. On Windows systems, there are numerous choices available, including Hummingbird Exceed and Cygwin/X. Most ssh clients can be configured to automatically set up a remote X display as part of the login session. This may happen without any action on your part; if you log into an OSC machine and the command “echo $DISPLAY” gives you more than a blank line, you need do nothing else. To configure this automated behavior with OpenSSH on a Unix/Linux/OSX system, you will need to either login in with the -X option or add the following to $HOME/.ssh/config on your local machine: Host * ForwardX11 yes ForwardX11Trusted yes Note that some visualization programs, such as AVS/Express, require an X server which supports the GLX extension for OpenGL compatibility.
