If X11 forwarding is set up properly then this command should display a string like "h02.uit.tufts.edu:10.0". If X11 forwarding is not set up properly then it will just return a blank line.
Sometimes I get X11 related errors about the .Xauthority file, what to do?
All accounts have home directories with 200mb quotas. If you are near the limit and try to login or use X based software, you may not be able to. Clean up by deleting some files, also delete the .Xauthority file, logout and back in and you should be all set.
I get an error about Mathematica missing fonts,etc... What does this mean?
