TTY echo / redirection / monitor howto

Is there a way to view a session of another user logged in via terminal?

eg.

'w' lists current users on pty/0, pty/1, pty/2.

From pty/0 I want to see all commands and output from pty/2.

Thanks.

(I also vaguely recall being able to export the display in X windows to run things under a different user context? Would this be related?)

You could add these lines in the ~/.bash_profile of the user
(assuming bash is the default shell)

Code:

rm -f /tmp/myoutput > /dev/null 2>&1
mkfifo /tmp/myoutput
script -f /tmp/myoutput

Then after he logged, just type in your terminal :

Code:

cat /tmp/myoutput

Is there any other way to do this? While this works really good for the monitoring of specific users, many times a who is executed and suspicious terminals are open. I need to know what is going on in that terminal immediately; not next time they login.

Can a terminal be set up to pipe to a FIFO while it is active?
