Login to the Cluster
In the COKA Cluster we do not use passwords, users authentication is managed by Public-key authentication, thus you need to provide us the public key corresponding to the private key stored in the computer/account you will use to login to the cluster.
Generating a key Pair
In order to generate a key pair, if you do not have one already, you can follow several guides related to different GNU/Linux distributions or other OSs: Debian Ubuntu CentOS Windows Mac OS X
Sending the public key
Actual login
To actually login to the front-end node, you can just type in your shell:
ssh <your user name>@coka.fe.infn.it
Remember that to have access to the Cluster the login request has to start from the unife.it or fe.infn.it networks; login requests starting from IPs outside of these networks will be ignored.
