Can you run the following commands on the 5.5.1 server with debugging enabled and post the output here? Replace xxx.xxx.xxx.xxx with the IP address of the 5.5.2 server.

Code: Select all

/usr/bin/php /usr/local/nagios/libexec/check_nagiosxiserver.php  --address=xxx.xxx.xxx.xxx --url='http://xxx.xxx.xxx.xxx/nagiosxi/' --apikey='r96rbk8p' --mode=iowait --warn="7" --crit="17" --debug=1
/usr/bin/php /usr/local/nagios/libexec/check_nagiosxiserver.php  --address=xxx.xxx.xxx.xxx --url='https://xxx.xxx.xxx.xxx/nagiosxi/' --apikey='r96rbk8p' --mode=iowait --warn="7" --crit="17" --debug=1
You may have run the netstat command on the wrong server. Can you run it again on the 5.5.2 server?

Couple of things that you can look at, login to the 5.5.2 server with the user account that is associated with that APIKey.
Click on the login name and verify that the API key is correct and enabled.

From the 5.5.1 machine can you run the following and report the output

Code: Select all

curl -vvv "http://192.168.4.3/nagiosxi/api/v1/system/statusdetail?apikey=r96rbk8p"

If this is all you are getting I question if there is a firewall between the servers blocking the connection. This curl output basically shows that 192.168.4.3 is not responding to the request.

Apart from the two firewalls on both linux systems, there is nothing blcoking the traffic.

I may have to put an acl on the router facing the 5.5.2 device and see if the traffic is getting there from the 5.5.1 device, but I'm pretty sure that I will see it OK, so the next step would be to do a tcpdump on the 5.5.2 system I guess or maybe start there.

This sounds like a good option, I would check the firewall on 192.168.4.3 also, as well as make sure the routing is correct and the 192.168.4.3 server can send the data back to the calling server.
