Linux Terminal: how to capture or watch other terminal session

Question

Let say, I access to a server using ssh. In the same time, there is another person accessing that server.

Is it possible to watch what is going on in that person\'s

Answer 1

To capture what Alice types in a terminal, and then the next day let Bob see what was typed -- without any risk of Bob accidentally typing anything into that terminal -- Alice can type "showterm" ( http://showterm.io ) in her terminal window to start the recording.

To share a terminal so Alice and Bob both see "the same" terminal window and can both type commands into that window, there seems to be three popular methods: Byobu, tmux, or screen.

(tmate is a fork of tmux that works just as well, perhaps better).

• "ask Ubuntu: Share SSH Session at login"
• "Remotely Working Together on a Terminal Session in Linux" (with screen)

Answer 2

You can also try "cat /dev/vcsa1"

Answer 3

If you mean that the other person wants you to see his console, you two can use screen to share a terminal. See http://www.gnu.org/software/screen/manual/html_node/Multiuser-Session.html for a full description of how to do it.
