Hi all,
we've got the situation that some users need passwordless ssh between
compute nodes. Management node is running PCM 4.1.1.1 with xCAT 2.8.2
underneath.
Since it's a comparably small cluster and only few users, they are
administered locally via /etc/passwd on the MN. /home is exported via NFS
and mounted on the CNs. It is possible for a user to log in via ssh on the
MN. However, the same user cannot connect to any CN, neither with password
nor without.
What has to be done to make login on the CNs possible for common users? And
if this works, I assume passwordless login should be possible if the public
key is included in ~/.ssh/authorized_keys with permission 600, is that
correct?
Mit freundlichen Grüßen / Kind regards
