NRPE Error in a new installation

[steveh]

Hi all,

I'm new to Nagios.
I installed the latest nagiosXI 64bit VM with the OVF file on our ESX server.
I installed the nrpe on a new Cenos 6.6 64 bit OS with yum install after adding the repository.
once done I configured the host on the nagios server and get the error "CHECK_NRPE: Error receiving data from daemon."
looking in /var/logs/massages I see the error "nrpe[11550]: Host 192.168.220.254 is not allowed to talk to us!"
The IP above is not of the nagios XI server but of the FW behind the NagiosXI server.
I added the allowed_hosts with the nagios server IP (in different VLAN then the host to monitor) but I get the same error.

I know that the FW rules allow all traffic from the Nagios VLAN to the host in test and vise versa so no port is blocked.

I appreciate if someone will direct me how to configure the agent correctly as I'm new to Linux and Nagios.

Thanks in advance,

Hi,

I managed to solve the FW issue.
The FW was doing a NAT within the LAN so I disabled the NAT and all was OK.
Now I have to understand why so many of the monitoring options are simply not able to get the service status like SSH server monitoring, HDD Status and so on.

Thanks

Can you show us an example of the error you are receiving?
