I think that the piece you may be missing is --pty, but I also don't
think that salloc is necessary.
The most simple command that I typically use is:
srun -N1 -n1 --pty bash -i

Hi,
I am trying to get interactive jobs to work from the machine we use as a login
node, i.e., where the users of the cluster log into and from where they
typically submit jobs.
I submit the job as follows:
vsc40075@test2802 (banette) ~> /bin/salloc -N1 -n1 /bin/srun bash -i
salloc: Granted job allocation 41
salloc: Waiting for resource configuration
salloc: Nodes node2801 are ready for job
…
hangs
On node2801, the slurmd log has the following information:

We are running slurm 17.11.4.
When I change to the same user on both the master node (running slurmctld) and
worker nodes (running slurmd), things work just fine. I would assume I need not
run slurmd on the login node for this to work?
Any pointers are appreciated,
