TO bypass a proxy server is possible LOL and that is hacking
There are a couple of attack ways, but they will get you kicked out of school.
- sniff traffic on your school network to see how the administrators themselves get online.
- portscan the firewall and see what ports are open, abuse or exploit one of those ports.
- try to ping something on the internet, it that works, ICMP isn't blocked;
which implies that if you write your own proxy server and client to hide
traffic in ICMP packets you will get outside
- buy a cellphone with gprs/edge/3g and connect that to the school PC to get online
- buy a hardware keylogger and connect it to your teachers keyboard,
see what his passwords are and if he has internet access with those.
- If the internet is blocked on your pc and not by means of a firewall,
boot your PC from a linux livecd to override any windows 'netnanny' or other tools.
