Is there a way to access/log in to an active session? (using putty?)

pts/0 is running a process on my computer at home, i'd like to see how far a long it is..

You can't with the current session, but in the future, ssh to the remote machine, run 'screen', then run your process inside of screen. use ctrl-a d to detach from screen and your process continues. to check on the process, ssh back to the machine and run 'screen -r' and you'll reattach to the process to check up on it.

Yup, screen is the way to go. There's a lighter alternative called dtach or something like that, but I never bothered to check it.

nohup is also a valid alternative when you dont need an interactive way back to the session. It will log all output to a specified file.
