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

   Code Block
   ssh-keygen -b 4096 -t rsa

   
   

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

   Code Block
   cat ~/.ssh/id_rsa.pub

   Connect to a cluster frontend node (izar, helvetios, fidis, deneb1).epfl.ch and paste the public key in the authorized_keys file:

   Code Block
   mkdir .ssh chmod 700 .ssh echo 'ssh-rsa AAAAXXX[...]' >> .ssh/authorized_keysssh-copy-id <username>@fidis.epfl.ch

   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.
