    Default SSH sessions keep disconnecting

    I doubt any of you can help, but I'm desperate.

    I'm trying to use a SSH client to run a simulation program on a Linux server. The simulations take many hours to complete, and so they have to execute unsupervised. However, well before the simulations can complete, the SSH clients I've been using have disconnected early.

    I didn't have this problem on my lab computer, which was running XP I think. But I no longer have access to it, so I'm trying to run them from home, running Windows 7, and now I'm running into this problem.

    I've tried using both Putty and another client called Private Shell Agent, and I tried fiddling with the settings, but to no avail.

    Any ideas?

    I was going to suggest putty but yeah.
    I don't have it installed at the moment so I can't look at the settings for you, but I suspect if you are having this problem while remote connecting and not in the lab, maybe its a setting server side, disconnect any remote connections that are inactive for a certain period of time.
    Speak with system admin I guess (lol generic response is relevant).

    failing that, dual boot linux? can you set up the program on your own machine?

    Maybe too late, but...

    If you're running a command on a server you can use the screen utility or something like tmux to start the command. From there you can safely log off from the server and be assured that the session will continue to run.

    This will start a new session:
    > screen -r

    When you're in the second session you can use the key combination 'control+a+control+d' to return to your actual ssh session. From there you should see a message that you've detached the screen. You can then type `screen -r` again to return to your session. Between logging on and off of the server the session should persist.

    I love your work with Subway, Jared =0

    But thanks, yeah I fiddled around with "screen," and I figured out that I have detach the window from the terminal session in order to not have it end when the terminal session ended.

    So it works! Thanks.
