Thread: how does a server without a dedicated monitor work?

  1. #1

    Default how does a server without a dedicated monitor work?

    When you need to change something on the server you can hook up a monitor and a keyboard and do it through the console.

    I would like to hook up an external monitor in this fashion for a desktop. The current video card can only support a single display. So I was hoping there was someway to use a second monitor as just a permanent console since simple text shouldn't require a video card?

    Am I way off base here? or could someone point me in the right direction?

    Hi
    Don't even need to do that, login from another machine via ssh, or if you want a GUI my preference is to use NX from nomachine, but the is VNC, RDP etc. You can also use a serial connection if you want with something like minicom.

    I always managed servers using ssh (as malcomlewis suggests). The only time I needed to consider connecting a monitor or an old fashioned ascii terminal, was if there was a hardware problem that prevented it from fully booting up, or if installing a new operating system release.

    I realise you can ssh in, but that doesn't help me.

    I want to connect a monitor to a desktop, probably via a usb video adapter, and use it as a permanent console (text only monitor). hoping that the simplicity of text only will not require a video card.

    servers don't have video cards, do they? so how do you run a monitor without a video card?

    Hi
    Not sure about a USB device and what linux support is like, most have a VGA card of some description. If you have a terminal you would use a serial port.

    so I can just plug the monitor into the serial port and a console/terminal would display on the monitor? (assuming a keyboard is plugged into the server to type with)

    I apologise if this is confusing or I am explaining it badly.

    I want to use the extra monitor to display a text only console/terminal that I can use on the desktop computer while another monitor has a gnome/gui/window system up.

    If by a monitor you mean just some CRT or LCD display then you need a video
    card of some sort to generate the signal. It need not be a fancy card. If
    you mean a dumb terminal (e.g. VT100) then you can just connect it to a
    serial port.

    its an LCD. Can you explain more about the VT100. I've wikipedia'd it, but don't quite understand. Does VT100 refer to the hardware? or is it software, like a dumb version of bash? What do you mean by dumb terminal?

    As venzkep hinted, a dumb terminal is more than a screen. It has its own microprocessor, graphics, and serial communication circuitry built in. The DEC VT100 is just one of many types that were available (and many others could emulate it). They were commonplace in the era of mainframe computing. If you really want to have an adjacent console, you could use an old laptop. I used to service Wyse teminals about 20 years ago.

    This link shows a VT100:
    http://en.wikipedia.org/wiki/VT100

    There are a number of programs that can emulate a VT100. Windows came with a
    terminal emulator and I'm sure there is a Linux version. As deano ferrari
    wrote you can use an old computer (It need not be a laptop) with a serial
    port to use as a terminal. But, of course, it has the video card you need.

    PS: My last terminal was a Qume QVT-102A. It died about 20years ago, probably
    right after deano farrari, and everyone else, stopped repairing them.
