I have a computer running Linux Mint 16 and my brother uses a Windows 7 Home Premium. For some reason, when I start a LAN world, it doesn't show up in the Multiplayer thing, but when he starts a LAN world, it shows up for me. I need help for I want to play with him.
I have two linux laptops, one running Ubuntu 14.04 and the other running Simplicity Linux. On both, I can run Minecraft OK, and can get onto servers e.g. Meepcraft.com, however I can't open a LAN. On Ubuntu 14.04, I can see the LAN opened by the Simplicity Linux machine, but when I try to enter it, I get a message "Failed to connect to server" and "java.net.ConnectException: Connection refused:". I'm not sure what to do about this and it seems similar to the threat above. I'd appreciate any help.
This kind of issue is generally a firewall problem. It can be on either machine, but in this case I would guess that the Simplicity Linux machine is blocking the inbound connection attempt.
Check your firewall on the server: sudo iptables -L
should give you a list of opened ports, 25565 should be one of them sudo netstat -nltpu
should show you a java application listening on that same port
