Hi,
I would check for established VNC connections this way:
netstat -tape | grep ESTABLISHED | grep Xvnc
As for warning connected users. If you see there is an established vnc session on port 5902, you could simply do:
export DISPLAY=:2.0; xmessage -center -timeout 60 -file shutdown.txt
/dev/null 2>&1
How can I determine what the user responds, is there errorlevels or anything like that? Hundred years ago I was making a lot of advanced BAT-files in msdos, but have not done much of those things in Linux yet. I could or maybe should find out reading man-pages, but have already asked. :)
What is the reason for doing ' > /dev/null 2>&1'
You could create a list of established connections, translate it to active displays (5902 -> 2.0 | 5903 -> 3.0 ...) and send out a message.
Hope it helps Olivier
It helps a lot, Thanks
