Diary - SSH keygen issue

There are cases where connecting to a server with SSH keygen doesn’t work.
I wasted two hours flailing around, so I’m recording this in case it happens again.

1. Typos

• Don’t make typos in authorized_keys
• When copy-pasting id_rsa.pub, make sure you copy the whole thing properly

1. Permissions
   • The .ssh folder should be 700
   • The .ssh/id_rsa file should be 644
   • Other files inside the .ssh folder should be 600
