Hallo everyone
we have recently noticed that when running nodes in configless and
dynamic mode, pam_slurm_adopt does not work properly, denying ssh access
when the user has a running job. We traced down the issue to the fact
that the dynamic nodes are registered with FQDN (e.g. c01.psi.ch), while
pam_slurm_adopt uses this routine
(https://github.com/SchedMD/slurm/blob/master/src/common/stepd_api.c#L181)
to guess the stepd hostname, using the host short name (so, c01). If we
use gethostname instead of gethostname_short then it works again. Has
anybody experience with this, and is there a way to have dynamic
configless nodes registering with the short hostname?
Thanks!
cheers
leo
