Problem codechicken/wireless redstone error

[eyeball114]

I am hosting this server for a few friends, ite previously ran fine on one of their machines not I am trying to host it from my ubuntu server. I have 4 other servers running fine. The only thing I have done was changed the server properties to one of my open ports and ran the start script.

Ubuntu server 12.04 LTS
Java: OpenJDK Java 7
