    Screen is useful for managing multiple SSH windows and also for maintaining an active SSH window even when your connection between you and your server is lost. This is useful is you run Centmin Mod install and/or upgrade commands and you have a flaky ISP connection to your server.

    To install linux screen and setup a dedicated screen for updates etc check out below tutorials

    Install is easy
    Code:
    yum -y install screen
    Screen tutorials
    I use screen alot of times with long term clients of mine, I setup a dedicated screen which I work in and survives when I log out of SSH, so when I return I can pick off where I left off on or check on processes or commands I may have left running for monitoring or analysis.

    Comes in handy :)

    @eva2000, you should look also into autossh, is available in AXIVO repo.
    Yes, I also use Windows, not just Linux. :D

    Actually the white background is default in RHEL6 distributions. :)
    For some reason, black hurts my eyes... probably because I'm to used dealing with text editors. :)

    Check the OQGraph functionality I enabled in MariaDB 10.0.12. :D

    Bringing this thread up for discussion again. Screen allows your SSH connection tasks (i.e. running Centmin Mod install etc) to survive SSH disconnections.

    For long tasks, I always use Screen session so I can return it after exiting SSH session.

    The only time I randomly lost SSH connection was with Putty, but ever since switching to a new SSH client, I've never experienced it. I guess it'll only be beneficial to me if an SSH connection hangs probably from a networking issue.

    I remember starting a thread asking about multiple SSH connections for different servers and someone recommended Screen to me. I found that using Xshell's tabs worked as an alternative too.
