Nagios Support Forum

Hi All,

I have installed Nagios core 3.3.1 on Linux server. And have install NAGIOS NRP on the client machine i.e WINDOWS server. This Windows server has NAT IP. The problem is we are not receiving alerts after 5mins.

Getting error as " Connection Refused by host".

Can anybody help me?.

Thanks in advance.

What do you mean you don't receive alerts after 5 minutes? So you got alerts for 5 minutes and then they stopped coming?

The issue here may be that you have not added the IP address of your Nagios server to the list of allowable hosts in your Windows NSClient++ config. This page explains how to configure NSClient++. The option you're looking for is called allowed_hosts.
