Introduction

There are two distinct ways to get full screen output over the network. One way is to create an X session with the remote machine. In effect your local machine becomes a graphics terminal of the remote machine. Typically, for PCs and X terminals, this is the way to work. You should have already tried this out in the ``Getting Started'' chapter when you logged into PPLXGEN or PPSLGEN from your PC. An alternative way to get remote full screen output is just to make a terminal connection (i.e. SSH to a remote machine) but then get full screen output from the it. For example, suppose you are on one workstation, say workstation A and then to SSH to another computer, say computer B, and want to get full screen output back on A. In general to work like this you must do two things:-

• Tell remote computer B to send its output to local workstation A.

• Tell local workstation A to accept full screen output from remote computer B.

It may seem odd that you have to do this. After all when you first log in remotely the remote computer has no problem sending output back to you although it is only working in line mode (i.e. one line of text at a time). Full screen mode working is far more flexible. You can even login to B and then get it to send its output to yet another computer. As you can imagine, this is not usually a good idea and if, while using a workstation, a strange window pops up that you weren't expecting, its probably that somebody else has directed it there by mistake!
