SSH authentication with keys

If you have a ssh server but you were wondering what these “keys” were and why the server kept saying that you weren’t authenticating with them, here’s the answer.

  • only support connections through the 2nd version of the SSH protocol (SSH-2)
  • use 2048-bit DSA keys for user authentication, without permitting authentication with passwords
  • allow only a specific group of users to authenticate

This tutorial will basically make it so that you don’t ever have to sign in via passwords and any hacker will need to break a 2048-bit DSA key to get into the account. A lot safer than a lot of password authentication.
And if you have no clue what I’m talking about… that’s okay. One day.. you too will see the light. Or not.
