Hello,
well, this is a difficult point to discuss - since I'm working as a school admin for the moment, too.
As an admin, I should warn you, that you are about to do evil things - but things are often not that simple...
However - as a humanist I really do hate this kind of censorship. And I'd like to encourage you solve this problem non-technical. You probably live in a (more or less) free country and this issues propably affecting your whole school - do something! Therefore, as a humanist I really to think that censorship should be stopped an information ought to be free for all!
And last - as a computer geek - I've never seen filter system, that is unable to break.
For your situation I recommend using jap. ( http://anon.inf.tu-dresden.de/index_en.html )
Features:
- Written in Java, useable on a many OS'es without installation - BSD license - Nice GUI.
- Can connect to the internet by proxy (if your school doesn't allow direct connections)
- The 600KB progam acts as a local proxy
- Your whole traffic is encrypted locally and sent to some proxy networks (called cascade), located around the world (in theory) / in Germany (since the system is in development) - Some cascades use 80/tcp.
- The ssl-backend assures you, that your communication is not intercepted in your school's network - if your workstation is not observed. (Teachers look at your screen or use vnc (etc.) to so)
- Allows P2P-Connecting - useful if your firewall blocks specific servers / proxies. It even implements some get-some-peer-adress-per-mail function.
Drawback: In past, the system had been watched by german authorities (at least one case is documented [sadly, the german law allows direct interception of traffic for crimes like terrorism, child abuse, etc - but it also gives you the right to communicate anonymously....] - however, if the system is used across the world this will no longer be possible).
Thus, if you need strong anonymity I recommend using JAP in conjuction with tor. Therefore you can be sure, that your communication is not intercepted or traced within the tor network and that German authorities are unable to backtrace your traffic.
Keep smiling
