This may be confusing because I have to SSH twice to reach the computer I work on. On my home computer, I begin by starting the X server. I run the command: bash-3.2$ echo $DISPLAY :0.0 And so it seems to be working fine. I then do: ssh -X computer #2 Warning: untrusted X11 forwarding setup failed: xauth key data not generated Warning: No xauth data; using fake authentication data for X11 forwarding. And that is returned. ssh -Y computer #2 returns no errors. When I do [mcoughlin AT lisa ~]$ echo $DISPLAY localhost:12.0 is returned for logging in with either the -X or -Y method. When I finally log into my work computer with either the -X or -Y method, -bash-3.2$ echo $DISPLAY returns nothing. And so when I attempt to use octave to plot, octave:2> plot(x) gnuplot: unable to open display '' gnuplot: X11 aborted. Obviously nothing happens. Can someone give me a clue?
