Scenario:
Nagios deployed on top of LXD using fan-networking (Nagios host IP: 10.66.0.15 in this deployment)
Host running on OpenStack, with both fan-252 and tenant interfaces well defined
Fan-network in itself seems to be working since Nagios can ssh into host; host can ssh into Nagios with no problem.
I can see on Host's nrpe-server service:
Aug 01 13:11:33 juju-d3ac24-kubernetes-1 nrpe[9406]: Host 10.66.0.15 is not allowed to talk to us!
Aug 01 13:11:59 juju-d3ac24-kubernetes-1 nrpe[10866]: Host 10.66.0.15 is not allowed to talk to us!
Which means nrpe-server is not aware that Nagios is reaching out through its own host IP |
