Before i trundled off to uni, my parents were massively into restricting everything I did... Unfortunately for me, my Dad is a software developer, so he knows just as much about computers as anyone. It became a bit of a silent duel. But we were both constantly trying to outdo each other, he always being on the lookout for better security whilst i was furiously trying to be able to change my MAC address and get the router to accept the new address...without access to the router... I even went as far as rainbow hacking his computer which uses XP. Microsoft really is not safe... Glad thats all behind me though :D
