Not only is this stupid, but it is a really bone-headed move that can land you in prison. Do you feel l337 that you want to open a backdoor on your school's network, or hack them for that matter? That is totally lame, and highly disliked. We can't stop you from breaking the law, but for your own good, don't try anything like that. Also, for your own good, don't post questions like this here because we really don't like reading them. Hope I helped, and please reconsider.
