[slurm-users] network/communication failure

[Turner, Heath]

Attached are iptables from master/hosts.  I think they look normal.

No firewall (as far as I know).

Is there a firewall turned on? What does "iptables -L -v" report on the three hosts?

If anyone has advice, I would really appreciate...

I am running (just installed) slurm-11.17.6, with a master + 2 hosts.  It works locally on the master (controller + execution).  However, I cannot establish communication from master [triumph01] with the 2 hosts [triumph02,triumph03].  Here is some more info:

1. munge is running, and munge verification tests all pass.
2. system clocks are in sync on master/hosts.
3. identical slurm.conf files are on master/hosts.
4. configuration of resources (memory/cpus/etc) are correct and have been confirmed on all machines (all hardware is identical).
5. I have attached:
        a) slurm.conf
        b) log file from master slurmctld
        c) log file from host slurmd

Any ideas about what to try next?
