Here is the scenario.  My local machine is
            dark.unix with ip address 1.2.3.4
My remote machine, on the universities network is light.unix
I log into light.unix with the command
            ssh -X light.unix
This opens up a terminal as if I had telneted into light.unix.  I then
try to run an application, say emacs, with the command
            emacs -display 1.2.3.4:0
This fails with the error message
            Can't open display 1.2.3.4:0
