Login VIA SSH to existing session.

[waxed]

I am in the process of emerging my system at home. I started SSH so i am able to login to the system. Is there a way to login to the session that is running on the box? I.E. i want to be able to watch the emerge install process via a SSH terminal. am i making scence here? lol

I think this is a dupe i found something similar to this sometime ago in the forums it mentioned something about using screen and backgrounding the session so that when u logged out and logged backed in it would be right there were u left off! or u could just start ssh and emerge from there

If you want to watch an emerge from a remote terminal, you have to start a screen session (you can do this from your computer at home, or remote comp after logging in through ssh),
type 'screen' at the terminal.
then start your emerge, or whatever...
If you want to log out while compiling your program, you have to detach screen.
To do this, type ctrl-a, then hit 'd'

You can now log out of system and have process continue. If you would like to reattach screen, type screen -ls (this will list all the running screen's)

then type screen -r screen.to.attach
