hi

what i will do this for my daughters… playing minecraft use with two computer linux (opensuse 15.0 and opensuse 15.2 beta)…
thank you
Minecraft uses TCP 25565 for communication, so you’ll need to open that port in your firewall on the system where you are hosting the minecraft server on.
You can open a port in firewall’s public zone by issuing:
sudo firewall-cmd --zone=public --add-port=25565/tcp
It will ask for your root password. See if this helps, if not - let’s try to debug why not.
ok i did comand firewall… but not works…nothing list of lan
Hi
Just tested here, minecraft server on Leap 15.1, client on Tumbleweed. Opening the port worked fine on the server side…
Can you confirm the rule on the server took, you might also want to switch to root user rather than sudo via su -
firewall-cmd --list-all
public (active)

Hi
Did you add the server ip address to the client?
i try restart firewall but there isone list in search minecraft lan: LAN WORLD but error message: https://paste.opensuse.org/48480590
but i click REFRESH result list is empty…but i restart firewall and back the list but 2 seconds after is empty (refresh)…what is problem from…?
Hi
Did you check the firewall command again, since you restarted the firewall;
firewall-cmd --list-all
I had to disable the firewall using
systemctl stop firewalld systemctl disable firewalld
like "The authentication are currently down for maintenance" in Minecraft Java Edition when connecting to a LAN IP address - Arqade describes, then set the subnet mask of my static IP address to 255.255.255.0 rather than 255.255.255.255, so MINECRAFT JAVA EDITION on LAN: opensuse 15, not works... - #2 by Miuku is probably correct if your network configuration is too, @manuel_songokuh.
