I have no words.
You couldn't ssh anymore because that command disables using a password when using ssh.
Has anyone told you that you're a dick?
You play the "i'm so much better than you" crap, but you're too immature to see that not everyone has the same experience that you do.
So instead of saying "Hey, you have to have some sort of authentication method, here's a URL for how key exchange works", you post this crap?
Keep this in mind: There's always *someone* better/more experienced than you are.
