I've LAN'd starcraft, Doom 2 (ZDaemon), and Quake 2 at school. My school doesn't have that program, but they have some methods of finding things. And I have methods of getting around it. They think to little of us; the password to the BIOS is the chipset's default.
My sneaky-assed way is: Ask to work in the Library for Advisory (before or after lunch. Its what you do when the other half of the school is at lunch), then sneak through the top floor. Using a stolen Janitor key, I get into the conference rooms. Librarians will let you in, but you have to have doors open, blinds up, lights on, and they come by every 5 mins or so if there's people in them. About 4 of us do this every day. We get 2 people into each room, then open the retractable wall and push the comps together. We log into keylogged school accounts so they aren't traceable to us, plug in our thumbdrives, and install + run the game. We unplug the comps from the school LAN and hook up our own ethernet. At the end we clear the files, registry keys, and then pull the plug on the comp. If you normally shut down, a few unkillable processes will report logs to the admins, and red-flag them if anything is installed. Between advisory and lunch, that's about 1/4th of the school day spent gaming. And on thursdays, school starts late so we game then too. Except you're actually allowed to at that time, so we don't need to be stealthy. I love thurdsays; 2 hours and 25 minutes of gaming
. Never been caught either. Proxies and such have been blocked and one was even shut down, but they're quite oblivious. They don't even have cameras in there, and they sometimes leave computers lying on the floor and such. I wouldn't take anything though, because then they'd set up cameras. D'oh.
One guy even brings a USB hub and fills it with flash-ram...
Nothing more fun than LANning at school. Note to anyone who is going to try to game at school: Make sure the game can alt+tab.
