Easiest way to cut off net access?
Okay my parents asked me if it would be possible to write a program that can limit the time frame during which the internet can be accessed from my sisters computers. I haven't done any type of real network programming in C++ (some in Java) and figured this would be a good project to get a little bit ahead of my classes and to not forget everything I learned over the summer. The problem is, as far as actually blocking the internet I don't know where to begin at all. I can make the interface and set it up for my parents to access the settings and change what times they can use the net but I don't know how to actually cut it off. I'm sure there are many ways I was just looking for any easy suggestions.
Thanks
