I have set up a droplet running ubuntu 14.04 and I have a minecraft server running. Port 25565 appears to be closed to external connections. I have run the command "iptables -I INPUT -p tcp --dport 25565 -j ACCEPT" however I still cannot connect to the minecraft server. Here is the output from "netstat -pln": " Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 774/sshd tcp6 0 0 :::22 :::* LISTEN 774/sshd tcp6 0 0 127.0.1.1:25565 :::* LISTEN 1056/java Active UNIX domain sockets (only servers) Proto RefCnt Flags Type State I-Node PID/Program name Path unix 2 [ ACC ] STREAM LISTENING 10211 1097/tmux /tmp/tmux-1000/default unix 2 [ ACC ] STREAM LISTENING 6942 1/init @/com/ubuntu/upstart unix 2 [ ACC ] STREAM LISTENING 7543 358/dbus-daemon /var/run/dbus/system_bus_socket unix 2 [ ACC ] STREAM LISTENING 8832 778/acpid /var/run/acpid.socket unix 2 [ ACC ] SEQPACKET LISTENING 7326 291/systemd-udevd /run/udev/control unix 2 [ ACC ] STREAM LISTENING 9475 1020/tmux /tmp/tmux-1001/default " I have been advised to listen for connections from all addresses however I'm not sure how to set this up. Could someone help me?

tcp6 0 0 127.0.1.1:25565 :::* LISTEN 1056/java

It's just listening on your loopback device. You need to get it to listen on your public nic.

I run minecraft servers off of droplets all the time. All ports are open unless you installed a firewall or used iptables to block the port. Make sure your server isant listening on the loopback ip (eg localhost/127.0.0.1).d

    I was wondering. Do you have any trouble with the mojang authentication servers? My minecraft server can't reach them and I'm not sure what to do.

sudo iptables -I INPUT -p tcp --dport 25565 --syn -j ACCEPT
sudo service iptables save
