10.4.3.2. Telnet and X
If you would want to use telnet to
display graphical applications running on a remote machine, you
first need to give the remote machine access to your display (to
your X server!) using the xhost command, by
typing a command similar to the one below in a terminal window on
your local machine:
davy:~> xhost +remote.machine.com
After that, connect to the remote host and tell it to display
graphics on the local machine by setting the environment variable
After completing this step, any application started in this
terminal window will be displayed on your local desktop, using
remote resources for computing, but your local graphical resources
(your X server) for displaying the application.
This procedure assumes that you have some sort of X server
(XFree86, X.org, Exceed, Cygwin) already set up on the machine where
you want to display images. The architecture and operating system
of the client machine are not important as long as they allow you
to run an X server on it.
Mind that displaying a terminal window from the remote machine
is also considered to be a display of an image.
