Hi all,
I have upgrade my cluster to 20.11.7 version.However I have found my cgroup
seems to be invalid.In my log files I can see :

...I really didn't want to wade in on this, but why not set up host
based ssh? It's not exactly as if passphraseless keys give better security?

Your mistake is that munge has nothing to do with sshd, which is the
daemon you are connecting to. It can use PAM (hence the ability to use
pam_slurm_adopt), but munge has no pam integration that I am aware of.
As far as your /etc/skel bits, that is something that is done when a
user's home is

We had something similar happen, when we migrated away from a
Rocks-based cluster. We used a script like the one attached, in
/etc/profile.d, which was modeled heavily by something similar in Rocks.
You might need to adapt it a bit for your situation, but otherwise it's
pretty straightforward
Hi Ole,
Thanks for the links.
I have discovered that the users whose /home directories were migrated
from our previous cluster all seem to have a pair of keys which were
created along with files like '~/.bash_profile'. Users who have been
set up on the new cluster don't have these files.

Hi Loris,
I think you need, as pointed out by others, either of:
* SSH keys, see
https://wiki.fysik.dtu.dk/niflheim/SLURM#ssh-keys-for-password-less-access-to-cluster-nodes
* SSH host-base authentication, see
https://wiki.fysik.dtu.dk/niflheim/SLURM#host-based-authentication

Thanks to everyone for their help, much appreciated.
Seems to confirm that things would be much easier if I could just figure
out a way to detect the issue from the prolog/epilog, rather than the
taskprolog/taskepilog!
All the best,

Hi everyone,
Thanks for all the replies.
I think my main problem is that I expect logging in to a node with a job
to work with pam_slurm_adopt but without any SSH keys. My assumption
was that MUNGE takes care of the authentication, since users' jobs start
on nodes with the need for keys.
Can so
