30 yesterday I also discovered that the default mysql port is blocked at school thus I need to change the port my server uses and I have no idea what ports are open at school. Last year they even said they would set the network more open as they can't stop us from "miss using" it anyway and this types of problems are just stupid.
/me slowclaps
let me guess, monday I will discover that both the default port for git and ssh are blocked because at this point that wouldn't surprise me >_<
