I Cant Connect to my Server

Hello, I have a dell poweredge 1950 with ubuntu installed on it. I set up a bukkit server on it and it starts flawlessly, but when I try to join it in minecraft it gives me the following error message: java.net.SocketExeption: Permission Denied
I can connect to ANY other server. It is only mine that says that when i try to join. Does anyone know the problem? Please help if you know. Thanks.

 

pootieloc First have you portforwarded properly/is it hosted by a company or your self. If hosted by your self how are you trying to connect to it? IP or via localhost/internal IP.

 

tcvs I am hosting it, and i was trying to connect with my local/internal ip so I shouldn't have to port forward (correct me if i'm wrong).

 

pootieloc You are correct. Do you get any message in your console when you try to connect to the server?

 

tcvs No it just said that error in my client and on the actual list it says cannot connect to server. It doesnt say cant reach server like for servers that are offline. I appears that there is something preventing me from being able to connect

 

pootieloc Ok so what do you have in the server address? If it is your IP don't post it just say External IP or Internal IP.

 

tcvs The internal ip

 

pootieloc try using localhost

 

tcvs I dont think that will work because i dont play on the same computer the server is being run on

 

pootieloc right ok.... I will have to dwell on this and think about it.

 

tcvs I got the server running there is a problem with getting worldguard to work though... Here is the message from the console:

I have no idea what is wrong if you can help please do

 

If you are not playing on the same computer that your server is running on then it will not work, and you will have to port forward. It looks like you WorldGuard is corrupt so I would re download a new copy.

 

1. Did you open the firewall in the server?
sudo ufw allow 25565

2. Did you install WorldEdit?
WorldGuard depends on WorldEdit
