No keys for the user, a common used ssh_known_hosts file and a central place to look for errors. Passphraseless ssh-keys I just dislike as they tempt the user to copy them to all remote location (especially the private part) to get more comfort while using ssh between two remote clusters, but using an ssh-agent would in this case be a more secure option. -- Reuti > ___ > users mailing list > us...@open-mpi.org > http://www.open-mpi.org/mailman/listinfo.cgi/users

You need to create id_dsa and id_dsa.pub on the client, as above. But it is the client's id_dsa.pub that needs to go into /home/user/.ssh/authorized_keys on the server, which seems to be not what the above recipe does. If that doesn't help, try adding -v or even -v -v to the ssh command to see what the connection is trying to do w.r.t. your keys.
