NRDP / NSCA not working

Hi all,
We've already set up all the config to let it work, but still no retrieving data from our deployed Nagios.
There's any restriction about versions to work together?
Thanks!

Anything that isn't ancient should work. What versions of everything are you running?
Also, is this related to
https://support.nagios.com/forum/viewto ... 55#p265755 ? Can we close one thread to avoid duplication?

Yes please close the other topic, I duplicated by mistake.
I'll check the versions and post it here ASAP.
Thanks!

Nagios deployed version 5.4.1
Nagios Central 5.5.5
I've already followed the tutorial and still not retrieving data.
Server restarted several times with no luck.

I've already updated the deployed Nagios to the latest version 5.5.5 and still not working.
Thanks

Both machines are now at 5.5.5, correct? Make sure that the remote machine can communicate with the central machine by running the following on the remote machine's command line:
curl https://central_xi_ip/nrdp -kv
Have you configured any hosts besides localhost so far? The Global outbound options(Admin > Check Transfers > Outbound Transfers) on the remote server will filter these out.
Also, you would be seeing new hosts and services come in under Admin > Monitoring Config > Unconfigured Objects) and in the /usr/local/nagios/var/nagios.log on the central server you would see entries like "Error: Got host checkresult for 'test', but no such host can be found". Make sure you're checking both of these locations.

In addition to what cdienger posted:
You're not seeing them in
Admin > Unconfigured Objects?
Please post your
/etc/xinetd.d/nsca file.
Did you restart xinetd after making the changes (if you updated it)?
What is the output of these commands (some of the commands may fail, send me the working ones):
Code: Select all
ss -nlp | grep 5667
netstat -ano | grep 5667
iptables -L
firewall-cmd --list-ports
sestatus
Can you go to
http://YOURXISERVER/nrdp/ or
https://YOURXISERVER/nrdp/ just fine through a web browser?

Thanks for your replies!
I've already made it work, and now I'm feeling so dumb
On remote machines, all the hosts were correctly set up.
I also tried with the direct IP just to check if it was a DNS problem - Not solved
Then Googleing a little I've found the same issue with another user, finish the URL with a simple /
Thanks for your time and patience and hope this helps another user.
