Sharing terminal with screen

From Akvo Labs

Screen is a program that allows two users to share a terminal session, both entering commands and seeing the others typing.

If screen isn't installed the is the first step.

sudo aptitude install screen

Then we need to change permissions to allow sharing. This is done once.

sudo chmod u+s /usr/bin/screen
sudo chmod 755 /var/run/screen

Now one user initiates

screen

When screen has launched a pair of commands starting with Ctrl-A are entered

Ctrl-A :multiuser on
Ctrl-A :acladd gabriel

Finally the other user logs on to the screen session with the first user's name

screen -x paul/
