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.
