Setting up passwordless SSH in 2 easy steps

There are times when you really want to get rid of SSH password authentication, however SSH is VERY picky about permissions etc. I just found out that there's a tool for that in all Linux boxes!

As promised, the two simple steps:

  1. Create your keypair (assuming you don't already have it ready)
    $ ssh-keygen -t rsa
    Make sure NOT to enter a passphrase, or you'll have to enter that every time you use the keypair!
  2. Copy it over to the server and make all necessary adjustments (create directory, fix permissions, etc)
    $ ssh-copy-id -i
    You'll be prompted for your password, and then notified that you can now try logging into the server.
  3. Enjoy!
