I'm looking to setup a Minecraft LAN server on my college's computers (I do a game development course and am currently on networking so this is relevant). Also, just before I get started, I own a legitimate Minecraft account.
There is one slight problem. I think Java may be blocked in the firewall (which I can't access because I'm a student) because when I try to login to the launcher it throws this error:
ConnectException: Connection refused: Connect
My question is this: Is it possible to launch the game without having to log in? I already have the game files from AppData copied over onto a flash drive (which I'm trying to run it from.
I heard from this question that you could launch it with a command while getting a username and session ID from here:
https://login.minecraft.net?user=<username>&password=<password>&version=13 but as that is a request to the login servers, it may or may not work at college. Is there any better way to launch it?
P.S. Counter-Strike and Cube 2 multiplayer worked so I know the LAN server will be okay. It's just launching the game I need help with.
