Sharing a Terminal Or SSH session using screen

Objective : I want to access a ssh session of  user1 on server  and see what all command he types in there using the same user  user1 on server

Solution : We can  do this using the multiuser function of screen.Assuming you use the same user name to ssh in and connect as the other user is using.

Step 1 :  One person needs to  create the screen by selecting a name for the session and then typing

# screen -L -S <SESSIONNAME>

Then other user  can ssh into the machine, and join this screen

sudo screen -x <SESSIONNAME>

And even after the session ends  you can view all the commands that were typed by the user1 looking at the .screenlog
