I want to duplicate output (and input) of one terminal to another. How can I do this?
Here is an applied scenario: I'm training someone 100 miles away. I can ssh into their system, while he will log in locally. I know how to directly write to another terminal: "echo Hi > /dev/pts/1". How can we share a terminal so that I can at least see what he is typing and what the output is. If I could type as well that would be great. We are talking console only here. However using X is a possibility if there is no console solution. Thanks, Cory
