Heh, I actually already made a nogui version that hosts on port 9876 for my own personal use (hosting on my linux VPS) but didn't post it. Remote hosting exploits doesn't work very well anyways.Like a few others I was in desperate need for "nogui + on specific port" version of HaxServer so I can host it on my linux headless server.
I started from The Real Jdbye's version and added two command line arguments.
ex: java -jar HaxServer.jar --nogui --port=8888
The jar is available here : https://mega.nz/#!x98wjAiJ!JxsEzxr2_zkl1QQYbRsp9Z5BN5GeBwBZIqArT45PwVw
