How to open port 19132?

sakaki- commented 4 years ago

Hello @mcsim415,

sorry, I don't quite understand what you are asking here? The image, as shipped, does not actively firewall inbound connections (although this can of course be turned on easily enough).

Is there a particular service, using this port, that you'd like to enable?

Best, sakaki

I couldn't find service command. How can i do? Screenshot_20191202-082325

22 port is open. But 19132 port is close..

deveworld commented 4 years ago

In fact, I can't use Linux well..

You need a service listening on this port also. Try running netstat -vatn and netstat -vaun to see which TCP and UDP services are running, on which ports.

I want open my minecraft pe server!

deveworld commented 4 years ago

Ummm

sakaki- commented 4 years ago

OK, from your netstat output, you have a UDP service listening on port 19132, presumably pocket minecraft protocol.

As such, you need to allow inbound connections on that port for UDP (rather than outbound connections for TCP, which is what you did above).

Try:

# iptables -P OUTPUT ACCEPT
# iptables -I INPUT 1 -p udp --dport 19132 -j ACCEPT

verify your ruleset with

# iptables-save

hth, sakaki

OK, so as I suspected, the port is open (you have in fact many rules ^-^ inserted to do that, and also, the default stance for INPUT is ACCEPT too; so nothing on this local firewall is in fact blocking you — which is as I would have expected, unless you had explicitly set up something to the contrary).

You also (per your netstat -vaun output earlier) have a service listening on this port, on all interfaces.

So you should be able to connect to this service OK. Check the IP address of your RPi using ifconfig, and then try to connect from another system on your local network first. Once that works, you can ensure port forwarding etc. on your external router is working.

I'll check it port state soon.

deveworld commented 4 years ago

Oh my gosh...

deveworld commented 4 years ago

It is still close

sakaki- commented 4 years ago

The issue is likely with your external router allowing / forwarding port 22, but not your target port. You need to fix that. The issue is not with the Pi.

Anyway, I am closing this issue and blocking you as a user, since your post above contains inappropriate sexual imagery.

I have reported this also to GitHub.
