Hi everybody, me and my bro recently bought minecraft BETA and it's an awesome game:)
But we want to play together on our local network(LAN). I perfectly created a server with my ip adres and port 25565. When I start the server, I don't have any problems and I can join it easly by typing ip:25565, but when my brother tries the server says: blablabla joined game but 10 secs later he disconnects, reason: internal exception: java.net.SocketException: connection reset.
 
here's the server log:
2011-01-21 21:40:26 [WARNING] **** SERVER IS RUNNING IN OFFLINE/INSECURE MODE!
2011-01-21 21:40:26 [WARNING] The server will make no attempt to authenticate usernames. Beware.
2011-01-21 21:40:26 [WARNING] While this makes the game possible to play without internet access, it also opens up the ability for hackers to connect with any username they choose.
2011-01-21 21:40:26 [WARNING] To change this, set "online-mode" to "true" in the server.settings file.
