Can I retrieve my disconnected SSH session?

[Atheus]

Hi all

my SSH (PuTTY) session disconnected halfway through an apt full-upgrade on a debian Etch box. I still have to hit enter and 'y' a few times before the process can complete and I really don't want to just kill the process and start all over again...

Any ideas how I can get that session back?

I do also have physical access to the machine if nescesary.

Not that I know of. Once tcp is broken you'd have to do a key exchange/session start.
I wouldn't kill the session unless you were absolutely sure.

Do you know if aptitude is even running still?

In the future you should use screen if you plan on having a long running job in a shell!

I never do anything like that outside of tmux (or screen if I'm desperate). Had to restart too many long running processes due to bad connections to ever be without one of those programs.

Oh damn you're right - aptitude died with the session 🙁

Thanks for the recommendations anyway I'll look into screen.

Yea, when a shell dies all of it's children get a HUP signal which, unless the app does something special to handle the signal, causes it to exit.
