"X11 connection rejected because of wrong authentication"

if this happens when you try to run an X program remotely:

You need to ssh -Y fnalmachine.fnal.gov to get X forwarding
You also need to have $HOME/.ssh/config set up correctly.

Host 131.225. .fnal.gov ForwardX11 yes ForwardX11Trusted yes GSSAPIAuthentication yes GSSAPIDelegateCredentials yes

Apparently it can also happen when your home area is full, so if the above don't help, try removing a file in your home area.
