PHP: Hey folks, Just moved into a dorm in the past few months and am on my school's wireless network and as it happens, I'm a lifelong PC user who bought a mac in July...meaning I don't know my way around anything. (Also a little nooby anyway.) But here's the deal. A stranger's computer shows up on my connections ('shared'). Are they actually connecting to my computer, or are they just innocently using the school's wireless as well? Bear in mind, I'm in a dorm of about 2000 students, so my instinct is that more than just that one have got to be connecting to the wireless. What's going on? And more importantly...if this Michael Kennedy is deliberately connecting to my computer... how can I mess with 'im?
