X Windows on PC Window Machines
Using "Xwin-32" X emulator  with the SSH client "Putty"

Run "Putty", BUT BEFORE you log into the UNIX machine, look at the preferences
and in particular "Security" and "Tunneling".  Look for a checkbox marked 'X11
forwarding' or 'X Window Tunneling'  and enable it.

Complete the rest of the setup for connecting to the remote UNIX machine,
and then SAVE IT as a session configuration.  This will allow you to just
pick this connection again, and automatically have the "X11 Forwarding"
enabled.

Now that you have enabled X windows, and save it, log into the UNIX machine.

Once you are logged into gucis, check that you have a X window connection by
typing...

  echo $DISPLAY

If successfull you will see something like

  gucis:10.0

You don't have to do the every time, just at this point and if you have
problems at a future date.

Now all you have to use an X window program, is start the "Xwin-32".

This should be configured to use "Multiple Client windows", and NOT a "single
window".  Also under "Security"  enable access from "localhost", as that is
where the emulator will see the connection comming from.

Test this with...

    xlogo

After a moment a graphical window with a colorful stylish X should appear, or
you get an error messge in yoru terminal window.  To get rid of the X, go to
the terminal window and type CTRL-C (hold down the 'CTRL' key then press 'C'
at the same time.

You can now run any graphical X window program you like on the UNIX machine.
Just login with "Putty" then when you want to run a X window program launch
"XWin-32" and run the program.
