Step by step guide

  1. On your local machine, generate an SSH key, ensuring a good key length and type :

    ssh-keygen -b 4096 -t rsa

  2. Copy the public key from your computer to any of the clusters

    ssh-copy-id <username>

    As the /home  is shared can be done by connecting to any of the clusters and will then work for all of them.

    You should now be able to login without a password on all the clusters including the data nodes.
