Blocking users from using vnc and ssh

Hi Pascal!
For what sort of system are you trying to write this script? From what it's supposed to do, I'm guessing it's a Linux or Unix system.

In any case, I guess there are two parts to the problem:
1. having a script to block ssh and vnc and one for unblocking them again and
2. starting the scripts at the right times

If you're using Linux, the first part seems to be an issue of setting iptables and the second is creating a cron job. You can find tutorials on both topics via Google.

If you're using Windows, the 2. issue wouldn't be a problem (there's something similar to cron in Windows), but the first one would very much depend on your firewall. If the Windows Firewall is up and running, you may be able to use that, but I have no experience in that area, so you'd better search with Google and hope that something comes up. Of course, you could always ask in our Windows Forum.

Greetings,
Nepomuk
