For my cluster, I have set it up this way:
- on the mater node, set up /etc/ssh/ssh_known_hosts
so that it has a line for each node in the cluster, the key
taken from /etc/ssh/ssh_host_rsa_key.pub
- copy master:/etc/ssh to each node in the cluster
- the new user script only adds the user to the master node
and then pushes passwd and shadow and possibly group onto
the other cluster nodes.
That's it. Hope that helps.
Best regards.
