Admin a screen multiuser

1. The host starts screen in a local xterm, using the command screen -S SessionName. The -S switch gives the session a name, which makes multiple screen sessions easier to manage. Code:

screen -S screen-test

2. The remote user (bjones) uses SSH to connect to the host computer (jsmith). Code:

ssh bjones@jsmith.computer.ip.address

3. The host (jsmith) then has to allow multiuser access in the screen session via the command CTRL-A :multiuser on (all 'screen' commands start with the screen escape sequence, CTRL-A). Code:

CTRL-A
:multiuser on

4. Next, the host (jsmith) must grant permission to the remote user (bjones) to access the screen session using the commadn CTRL-A :acladd user_name where user_name is the remote user's login ID. Code:

CTRL-A
:acladd bjones

5. The remote user can now connect to the hosts 'screen' session. The syntax to connect to another user's screen session is screen -x host_username/sessionname. Code:

screen -x jsmith/screen-test
