Nagios Support Forum

I'm very sorry, but this ended up being a firewall issue. Our next-gen firewall was doing some inconsistent things that weren't getting logged, so I missed it. I really appreciate your time on this. FYI for anyone running PAN-OS firewalls, entering "nagios" as the application and "app...

Also keep in mind that this worked before I made a change. The only change that was made was to the IP address.

NMAP shows it open. [root@nagiosxi libexec]# nmap 10.33.16.39 -p 5666 Starting Nmap 6.47 ( http://nmap.org ) at 2017-11-29 10:51 CST Nmap scan report for redrad01.uark.edu (10.33.16.39) Host is up (0.0012s latency).

ScottG , Are you able to nmap the nrpe client server from the Nagios server? nmap <target IP> -p 5666 What happens when you run service nrpe status on the remote server? Do you get any errors? I've seen some old bug where nrpe.pid file would not get properly created/replaced. So if you're able to f...

Hey ScottG, just checking in to see if your issue is resolved? Did you have any more questions? Or did you figure this out? I apologize. I have not circled back around to this yet. I can say that the troubleshooting tips in that link did not solve my issue. I need to do more looking at it though. I...

Hi, I migrated a host from one network to another and subsequently had to change the IP address. Now, my check_nrpe commands return SSL error on the Nagios XI server: CHECK_NRPE: Error - Could not complete SSL handshake. And on the client syslog: Nov 13 15:50:54 redrad01 nrpe[28397]: Error: Network ...

Go for it. Thanks again.

Looks like an issue in your ssl.conf. Specifically this line: RewriteRule nagiosxi/api/v1/(.*)$ /usr/local/nagiosxi/html/api/v1/index.php?request=$1[QSA,NC,L] Has no space at the end of the request which is going to do some potentially nasty things to the rewrite. Add a space to the end and see if ...
