I am running Mac OS X 10.7 on a MBP and OS X 10.8 on a Mac Mini. I can connect to the Mini via ssh without any issues.
I am running GNS3 (Network simulation) on the Mini and have configured it so that when I connect to one of my routers via the console, a Terminal window is opened.

On Linux I can connect to a remote terminal sessions if it's using screen or by connecting to the tty.

I would like to connect to the remote Terminal already open on my Mini from my MBP.

Do I need to run the equivalent of screen to be able to do this?

When I do a ps -aux on the Mini I get:

885   0.0  0.4  2622240  18368   ??  S     2:19pm   0:16.27 /Applications/Utilities/Terminal.app/Contents/MacOS/Terminal

Is there a way to connect to this terminal from a remote computer when I am connected via ssh?

What does -psn_0_561289 mean?

Can this identifier be used to connect to this terminal?

    The equivalent of screen on the Mac is screen. Have you tried doing it the same way you do it on Linux? Nov 13, 2013 at 15:39

Screen is the best way to do it. The command is available under both Mac OS X 10.7 and 10.8.

I configured the console sessions in GNS3 to use Terminal and screen with the following command:

/usr/bin/osascript -e 'tell application "terminal" to do script with command "screen telnet %h %p ; exit"'

This can be found in GNS3>Preferences>General>Terminal Settings

Then I list the screen sessions in my remote ssh session with the command:

screen -list

and... finally connect to the required router with:

screen -D -r <name of session obtained with "screen -list" above>
