I’m trying to find out all the ports used by Nagios infrastructure components in a distributed architecture. The idea is to identify the firewall changes required for the implementation. As per documentation and information on web I notice the following ports. Please let me know if I missed anything
Port 80 for Console Access on Primary Nagios server (including web server)
Port 5667 for NSCA on Primary Nagios server
Port 12489 on Windows clients for NSClient++
Port 5666 on Linux clients for NRPE daemon
Is there any other port on the Primary Nagios server which is listening for reports from clients?
Also, is there any port opening required for any port on the distributed Nagios server which sends reports to the Primary Nagios server.
Thanks in advance
