Hi.. I am developing the utility that will block Im messanger. I am able to block yahoo,msn,edonkey,irc and many other protocols using tcp reset methods.But for fasttrack i am not getting any signature to whom i will send the tcp reset packet.I am not able to block it but I am able to detect the fasttrack(kazaa) using UDP signature.but i am not able to block it? can anyone suggest me how to block kazaa programatically. thanks in advance..
