However this particular server has power to stop internet access for
that particular client.
To do so suppose I will send block internet message on that machine.
There's no way for one computer to block another computer's network
access. That would be considered a denial-of-service attack.
You would have to write a program that was installed on the client
computer, and when it received a message from the server it would do
something to reconfigure the client's network settings to block access.
I have no idea what that something would be, and you haven't given
details. What exactly do you want to block? All network protocols or
just HTTP? All destinations or just ones outside the local network?
Should this apply to just the currently logged-in user or to all users
of the machine? Should incoming connections be allowed?
This sounds pretty difficult. It would at least require using root
privileges to mess with system configuration settings, and might
require a kernel extension. Are you sure you want to get involved in
this? I think it would require a real low-level OS X guru.
