[Solved]Dedicated Server connection issue

[Grimson]

I have been trying to set up a dedicated server on a Linux box on my LAN just for private use in the house. The problem is I can't get the client to connect. I used DoomSlider's update script to update the game install then I run the dedicated server script. If I look at netstat you can see that java is listening on port 4242 and if I run a port scan from my other computer you can see that the port is open and filtered. The problem is that when ever I run the client and try to connect to the server it looks like it connects then errors out when trying to establish the socket connection. I have updated java to the latest version and I am at a loss as to what to do next.
I have java 1.8.0_51, am running Debian wheezy and the client is on Ubuntu 14.04.

Spoiler: Relevant part of Terminal Output

p.s. can you run the client from terminal with the -client argument without harm.

Does it work fine without doomsiders thingy? not sure, but he is adding in some networked stuff iirc, and they may be interfering

I am running doomsiders old version (17.1 lite or something) the only things i had to do to make it work was install java and run the start script. "./starmade/starmaded.sh start"

what does your server.config look like? is it still set to 4242?

I am starting to suspect that it is something with the OS. I was running a Minecraft server on the computer as well but that has started giving the same problem now and it has persisted through a java update.

Got it to work. There was a config for open ports that I didn't know about. So I just spent two days trying to fix a problem that was caused by I firewall. I can't believe it.
