Add an ssh key

• Create new key from your local machine (if you don’t have one):
  • On Windows: ssh-keygen works but it’s fussy
  • I named it id_rsa_test_user (but then I reverted to my personal id_rsa!)
  • I didn’t use a password
• scp the key to the server
  • scp -i ~/path/to/do4ds-lab-key.pem ~/path/to/id_rsa.pub ubuntu@@$SERVER_ADDRESS:/home/ubuntu
• On server:
  • mv & chown to user
  • su test-user & cd ~
  • mkdir -p .ssh, chmod 700 .ssh, cat id_rsa.pub >> .ssh/authorized_keys
  • chmod 600 .ssh/authorized_keys
  • rm id_rsa.pub
