On your local machine, generate an SSH key, ensuring a good key length and type :
ssh-keygen -b 4096 -t rsa
Copy the public key from your computer :to any of the clusters
Connect to a cluster frontend node (izar, helvetios, fidis, deneb1).epfl.ch and paste the public key in the authorized_keys file:
mkdir .ssh chmod 700 .ssh echo 'ssh-rsa AAAAXXX[...]' >> .ssh/authorized_keysssh-copy-id <username>@fidis.epfl.ch
/homeis 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.
