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.

Having SSH open to the internet is normal. Don't use password authentication with weak passwords.

yeah no I should have considered that. didn't lick the most secure password. will change when I get home

Don't use passwords for public SSH in the first place. Disable password authentication and use pubkeys.

And disable ssh to root. Hell, just disable root login altogether and use sudo.
