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 -- Wojciech Komornicki
