###How to share a terminal session with Screen

# install screen
apt-get install screen

# create a user 
adduser demo
# if need be, set the new user password
# passwd demo

Then in a terminal session

# connect as the new user
ssh demo@130.56.249.78

# start a new screen session
screen -d -R shared_session

Then in a new terminal session, connect as the same user

ssh demo@130.56.249.78

# join the current session
screen -x shared_session

To adjust all shared users to the dimensions of the current terminal

(Ctrl + a) F

Note that typing exit will kill the screen session for all parties :( Detach is the way to go if you want to exit...
