For example, consider a scenario where you need to install the adapter on a remote HPUX machine (named itaska). Because you have a Solaris 5.6 machine (named
alaska) that has a video card and monitor installed, you can run an X-window application on it. So you decide to use telnet to connect to
itaska from
alaska.
When you telnet to itaska, you would not get access to
itaska's monitor and would be unable to display an X-window application. That is why you must set the
DISPLAY variable, which instructs the X-server to redirect all windows to the computer set in the variable. Before doing so, the computer (specified in the
DISPLAY variable) must give permissions to share its monitor.
