How to tell if someone is connected via vnc

[Henning Larsen]

Thanks for the answer :)


I have made a file "ww" that is executable containing:

"netstat -an | grep ESTABLISHED | grep -v 127.0.0.1".

Is this sufficient to tell if any are connected / logged in?
Is there any way to tell people logged in via vnc that I am going to
reboot the system? something like 'wall'?
