I am setting up a cluster with OpenPBS 20. I want the authentication to be handled by Munge. I installed Munge on all nodes and activated the service. Then I created a Munge key, copied it to all nodes (
/etc/munge/munge.key), added the line
/etc/pbs.conf on all nodes and restarted the nodes.
Now when I run
qstat -a it gives me the following error:
# qstat -a
auth: error returned: 15029
auth: Failed to send auth request
No support for requested service.
qstat: cannot connect to server node01 (errno=15029)
Any idea what’s wrong?
Please check the /etc/pbs.conf file and see whether PBS_SUPPORTED_AUTH_METHOD=pwd
If not please set it and restart the pbs services.
It still doesn’t work. My head node acts as a compute node too. I have the following in /etc/pbs.conf:
@dambuduk please set PBS_SUPPORTED_AUTH_METHODS=munge not pwd
qstat: cannot connect to server node01 (errno=111)
@dambuduk Please change key name from
PBS_SUPPORTED_AUTH_METHODS then restart pbs
Thank you @hirenvadalia . For everyone’s information , a snippet from the PBS Professional 2020.1 Big Book documentation:
Thank you @adarsh and @hirenvadalia ! Authentication with Munge works now.
