How to disable Internet (or block all ports)?
-
I am trying to create an application that will shut down all ports and disable internet access but I have not been able to do so. First of all I don't know how to go about blocking ports at all; while I did try to use blocking sockets they won't work if port is already in use WSAALREADYINUSE or something. Second of all I don't think that that would be efficient method to block internet access as I would probably have to open thousands of sockets in order to block thousands of ports. What I realy need is a way to disable internet (dial-up AND LAN) access by simple click of a button even if computer already has internet and server applications running, while preserving LAN operational, and also to be able to enable internet access by simple click. Please help me with this, I was searching net and books for weeks now but I still didn't come up with satisfying solution. Thank you, Sasha.
