Hi,
Hope you are having a good day!! ...

I have attached the latest NCPA rpm package, let try remove your current NCPA package and re-install again.

As "root", please run the below command on your NCPA agent machine: Please answer "y" when prompted.

Now, please download the "NCPA.tar" file and put that on "/tmp" of your NCPA agent machine.
Please remember to copy it as "binary" package.

Please run the below command on the NCPA agent machine: Please anwer "y" when prompted.

Now, please follow the below KB for setting up your NCPA agent:
https://assets.nagios.com/downloads/ncp ... g-NCPA.pdf

Please run the below command to check status of ncpa_listener:
Best Regards,
Vinh

Thanks for provideing the installer and the steps.

It did install appropriately, additionally we had to add the firewall rules as below, then the communication was also fixed.

firewall-cmd --zone=public --add-port=5693/tcp
firewall-cmd --zone=public --add-port=5693/tcp --permanent

Great!! .... glad that NCPA is working ...

May I close this thread?


Best Regards,
Vinh
