VNC to view a window open on display :0

By smtkr

  1. Hello all. I have some processes running at work on the physical machine that are going to take hours. I want to go home and then check the results that are displayed in a window on the physical machine ($DISPLAY is :0). It is a RH:EL machine and I can VNC into it from home via a secure tunnel. Is there any way for me to get a window on display :0 to show in a window on my VNC session (i.e. $DISPLAY is :2)?

    tools like pcAnywhere, but you better check with the IT folks - - this can be
    a security issue.

    No way you can do it now :p

    You can configure X to allow VNC connections to the real :0 display instead of the virtual VNC displays, but you should have done that before. You need to load the "vnc" module in X configuration and set up a password. Then restart X.

    What you could to is to grab a screenshot of :0 and look at that.

    Depending on the specific program you may be able to open another session using your home computer as the X server and get the window on your local screen.

    Thanks for the info. Someone from work actually came in over the weekend and snagged the required data for me because he wanted to run some other tests.
