Exceed is an X Server program that you run on your Microsoft Windows personal
computer. It provides the graphical features of an X
Server for use with remote UNIX machines.
The X Windows system is a GUI -- graphical user interface -- that allows you
to display on your local system -- in the case, your personal computer -- the
graphical output from commands that are run on a remote UNIX system. This allows
your personal computer to do what it does best -- display graphical ouput --
while the remote UNIX system is doing what it does best -- running programs
or number crunching.
There are two classes of UNIX programs that benefit from
using a X Windows display: number crunching programs which produce graphical
output, such as SAS, SPSS,
Octave (a MATLAB
clone), and Maple; and utility programs
such as ghostview (a PostScript
document viewer), xrn (a newsreader), and
info (online IBM manuals on tigger).
These documents give step-by-step instructions on how to setup and
use the Exceed X Server in two different modes:
- Using the
unsecure Xhost security
-- where persmissions are given
based on the remote host's name, allowing anyone logged on to that
remote host to open an X Window on your personal computer and
worse -- to read anything that's in any X Window on your
personal computer and to change your X Server settings -- and
- Using SSH X11 tunneling,
which limits acess to your X server
only to X Windows programs that you start, and which is much
easier to set up, too.
