Generating SSH keys at the local host: super simplified

 

Some installations require us to “ssh” to the same host. I spent numerous hours troubleshooting though this process is supposed to be very simple and easy.

I learned these steps after quite a few unsuccessful attempts. I have been using them ever since and they always worked for me. Please add your comments / remarks / observations.

  1. cd      (go to home directory)
  2. ssh-keygen -t rsa; cp ~/.ssh/id_rsa.pub ~/.ssh/authorized_keys    (copy to keys)
  3. chmod 700 .ssh
  4. chmod 644 .ssh/*.pub
  5. chmod 600 .ssh/id_rsa
  6. chmod g-w,o-w ~

Problems with “ssh” keys is mostly to do with file / directory permissions.
