Hi
I built Beuwolf cluster using OpenMPI reading the following link.
http://techtinkering.com/2009/12/02/setting-up-a-beowulf-cluster-using-open-mpi-on-linux/
I can do ssh to my slave nodes without the slave mpiuser's password before
mounting my slaves.
But when I mount my slaves and do ssh, the slaves ask again their passwords.
Master and slaves' ssh directory and authorized_keys have permission 700, 600
respectively and
they owned only by owner mpiuser through chown.RSA has no passphrase.
Please help me on this matter.
