NCPA 2.1.8 changing permissions of /usr/local/ncpa/var

[Sampath.Basireddy]

Hi There,

Does NCPA 2.1.8 upgrade change permissions of "/usr/local/ncpa/var"?

We recently started upgrading all agents to 2.1.8 and if not all but most of the agents are not coming up any more.

Here is the error when we try to start the agent and how we are able to fix it. I am trying to understand is this an expected behavior?

Code: Select all

[root@server1 root] # service ncpa_listener start

Starting NCPA Listener: 2019-08-23 10:12:35,842 14965 ERROR failed to start due to an exception

No, it is not.

What were the permissions of the "/usr/local/ncpa/var" PRIOR to upgrading the NCPA agent? What is the version of the agent that you upgraded from? What OS/architecture?

How the "old" agent was installed, and how it was upgraded, e.g. via rpm/deb installer or using the Nagios repo?

Have you hardened/modified the server in any way? Is SELinux running?

We will try to recreate the issue in-house, when you get back all of the information that I requested. Thank you!
