CHECK_NRPE: Receive header underflow - only -1 bytes receive
Posted: Tue Jun 14, 2022 6:34 pm
Hello everyone!
I am currently facing some issues with my Nagios and NRPE configuration. When i try to run a check from my Nagios server, I get the following errors, where the 172.17.0.4 is the IP of my remote host (nrpe.cfg has my Nagios server IP in allowed hosts and also the port 5666 is listening):
Also, I have tried different ways of installing nrpe on my remote hosts, but I still cannot find one from one single place that works, I ussually combined them, due to the fact that I got errors. Could you also recommend me a trustworthy site or guide for nrpe installation?
Thank you and please let me know if I need to provide something additional.
