ummorpg network_listen/accept/bind failed

I was able to follow the n00btuts tutorial to get ummorpg running on a dedicated server but I made some changes to the game(just swapped out a character prefab and took out the point to click using a tutorial online) and now I'm getting these weird errors that prevent the server from working properly. Calling all linux gurus! What do these errors mean, and where can I fix them? bindings.h? I have no clue where this resides. The game works fine on a local host. I'm not sure where to apply pressure.
