I remember a Linux script was made that would remove internet access (or restrict it) on pair with the one you suggest (it could do a lot of other things too - most importently it removed the admin access).
Ultimetly they all fail because they are to easy to cheat (you have physical access to the machine, you can hack it) and while the internet restriction did not need happend on you computer (just one in the path of yours) you will properly have access to that one too (unless you are at your job).
It seams, unfortunetly that the only thing that works is willpower. |
