Connecting: Logging In to Another Computer: ssh, SSH Keys and ~/.ssh/config.

Updated

  1. Logging In to Another Computer: ssh (Journeyman): ssh user@host opens a shell on another computer right in your own terminal, asks the first time whether that computer is really the one you meant by showing its fingerprint, and exit brings you home; you can practice for free on your own computer with ssh localhost.
  2. SSH Keys and ~/.ssh/config (Journeyman): An SSH key pair logs you in without a password: ssh-keygen makes a private key that stays on your computer and a public key you hand out, ssh-copy-id puts the public key on a server, and a Host block in ~/.ssh/config gives the server a short name.
