How to securely and automaticaly login via ssh without typing password

  1. On the server, e.g. server, create a .ssh folder:
mkdir -p ~/.ssh
  1. On your client, generate a SSH key pair (ie public key, id_rsa.pub, and private key, id_rsa):
ssh-keygen -t rsa

Just hit "ENTER" for the passphrase. This selects the default behavior.

  1. From your client, copy the public key, id_rsa.pub, to the server:
cat ~/.ssh/id_rsa.pub | ssh server 'cat >> ~/.ssh/authorized_keys'

Note: keep your private key, ~/.ssh/id_rsa, PRIVATE !
