Hello, I am a Senior at high school, and i want to hack the network to make a prank that will earn my legacy. I would like to send a broadcast, or anything else you can think of that would be fun and doesn't cause destruction (I would like to graduate). Since I am currently enrolled in a CCNA class, I will not be pulling off the prank until late May (I would like to keep my Tech. privileges). Now I do not have many rights on the computers as I am a student, but due to our crappy tech. officials, I have found a few ports unused, that they forgot to disable (I could bring in my laptop). I know the Broadcast IP, but am clueless to the program I would need to send the message. I don't have to worry about getting caught while I'm doing it (my teacher will turn his head), but I know I will be caught within minutes of the broadcast taking place. Thanks for your help, I will try and video tape the broadcast for some youtube fun.
P.S. This is not one of the many messages trying to get around the school philters, I don't care how to, I can look at nasty sites on my own time.
