Eero,
where did you installed this nrpe package? is selinux running enforcing
mode (getenforce command), try disabling with setenforce 0. why you are running it under xinetd as usual way is to run it as nrped daemon.
For NRPE I usually do a source install with these flags:
./configure make all make install-plugin make install-daemon make install-daemon-config make install-xinetd
Rather than a yum install. If I install the nrpe package from yum I don't find a check_nrpe script on the system for some reason!
I demonstrate this on another system than the ones I've been working with in this thread:
[root@monitor1:~] #rpm -qa | grep nrpe | grep -v mcollective nrpe-2.15-2.el7.x86_64
[root@monitor1:~] #find / -name "check_nrpe" [root@monitor1:~] #
So I'm more comfortable with a source install.
test against with check_nrpe, not using telnet.
I actually solved the problem by adding the port to tcp instead of udp on the puppet host:
firewall-cmd --permanent --add-port=5666/tcp
Then from the monitoring host:
[root@monitor1:~] #/usr/local/nagios/libexec/check_nrpe -H puppet.mydomain.com NRPE v2.15
So it's all good at this point. I'm not sure why the instructions I followed said to open up the port under UDP.. Had I just done what I did I would have saved a lot of trouble..
Thanks for the input guys!! I'm glad the problem is solved now.

Back on the puppet host I verify that the port is open for UDP:
So why are you opening a UDP port?
