I am following this tutorial: https://www.spigotmc.org/threads/best-practices-for-minecraft-linux-in-general.4223/ I tried disabling the ability to login to root. I am sudoed atm. I typed: "nano /etc/ssh/sshd_config" It brought up this screen: https://gyazo.com/182fceb8ee43741cd905e2c0ec15a193 https://gyazo.com/8fd32e1e25d1f4ded4ab12a78595a13c (idk why it's typing the ^C as I haven't done anything..) Why is it different then what the tutorial said I was supposed to find? How can I correctly do it? Note: I'm new to this so please don't use your fancy words I won't understand The tutorial says: Modify your SSHd config: Now you're probably thinking "Why would I need to do this? It works, right?" and you'd be right, however a nice touch always is changing a few basic things to boost your security. First of all disable root. You have no idea how many times I have to tell people, disable fucking root, you have sudo so why would you need to login as root? First of all, open up your sshd config: nano /etc/ssh/sshd_config Once you've done that, look for the words "PermitRootLogin" If it says "PermitRootLogin yes", change it to "PermitRootLogin no" What this will do is disable SSH logins to the user root, you have sudo -s, so who cares, you certainly don't .
