Blocked, but pingable?

[Deas_Voice]

Hello, I'm wondering if there is any way to connect to a server with rc or client, even if it appears to be blocked, but i can still ping server's ip and do tracert, netstat ect on it-

i'm wondering this because of that, in school, we have often long breaks that i feel that i can kill some time with doing some work on graal, but i can't because of the "block", it is obvious that we shouldn't game at the schools wifi but cmon, msn works, facebook, etc, so why wouldn't a "text program" like RC work?

any ideas how to "by-pass" this?
