Ports used in Nagios infrastructure

[Ford, Andy]

Depending on your setup, you might want to give yourself some way to send configs to the distributed collectors like ssh/scp.



Some folks also like to run all web servers on SSL, so you might want to make sure port 443 is open too.

Subject: [Nagios-users] Ports used in Nagios infrastructure

Hi,

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,
Jerry
