    Is there any way to connect to an existing SSH session terminal?

    My main PC crashed whilst I was working on my Linux box in the background in an SSH window. Now I've got a lot of work in that terminal window (unsaved of course) that I need to get back. I need to be able to connect to that teminal (pts/0)

    Anyone know if it's even possible?

    What were you working in? most text editors autosave every so often so you could be fine.

    Nah, was writing my make file for a new install of Gentoo. Lots of options and I hadn't saved once :(
    Bugger.

    Anyway it seems (...) that once a session dies it's gone, unfortunately.

    I use screen for this very reason. If your SSH session crashes/hangs, you can reconnect to the screen session from another/new SSH session.. very handy.

    Answer that question.
    Most decent editors will allow recovery from a crashed session.

    Like cgarvey, I tend to use screen in those situations too.
    It's a major help when you want to be able to let your modem hang up...

    screen makes baby jesus smile. It is one of the things I absolutely love about Linux/Unix. It has saved me so many times, and has also made my work alot easier. To start screen, just type screen and hit enter to get rid of the welcome message. To detach a screen session just type "ctrl + a + d" To resume a screen session then type "screen -r". If the session is already attached you can do "screen -x" to attach to it, even it it's already attached. This is useful when you are connected to a UNIX server, but you get disconnected on dialup or whatever. Screen is alot more useful than this and it's worth reading up on it. Also, when in screen you can open up more windows by typing "ctrl +a +c" and switch between windows in screen with "ctrl +a +p". Of course, when I say + here I just mean and, you don't hit the + key :)

    I will be setting this up when the machine is up and running, I've only used it before to parallel fetch and emerge. I didn't realise it was so versatile.

    I was using nano to write my makefile. I managed to get it back anyway, and am on my way again. (Had a busy day at work yesterday so didn't get a chance to work at it)
