I just setup a minecraft server on an old laptop, but to make it acessible i needed to open up a port. Currently, these are the ufw rules i have. when my friends want to connect, i will have them find their public ip and ill whilelist only them. is this secure enough? thanks

`Status: active

To Action From


22/tcp ALLOW Anywhere Anywhere ALLOW my.pcs.local.ip`

also, minecraft is installed under a separate user, without root privlege

Why is port 22 open? Is this on your router as well or just the server?

This is SSH, which you should pretty much never have open (to the internet! Local is fine) MC is by default 25565. You will have every bot on the internet probing that port.

ssh is local only. so I should change all ports from default then huh

Your ssh rule says it's from anywhere. You want to change port 22 to 25565, and run /op username on your Minecraft server to whitelist your friends. Make sure your whitelist flag is turned on with your server config.

Instead of allowing traffic over your port from anywhere, you can specify your friend's external IP.

You can test it out by running 'telnet ' to check if the port is open. This is best done from another network.
