Hello,

NRPE 3.0.1 stopped responding after I upgraded to macOS Sierra.
check_nrpe returns

(No output on stdout) stderr: connect to address 10.x.y.z port 5666: Connection refused

This may be a macOS problem, but any ideas would be appreciated.

I have NRPE running via launchd. I reenabled and restarted it, but still no response. I turned the firewall off and it made no difference.
Here is my launchd file:

</plist>

I see no messages in /var/log/system.log.

Thanks,
Michael

Let's nmap the Mac from the XI server:

nmap <mac IP>

Can you also check over our troubleshooting guide? It is quite extensive:

Other things to confirm:

You can do do a netstat -an | grep 5666 on the Mac Terminal to ensure it's listening.

Also an ipfw list from Terminal will show loaded fw rules.

Note: Those commands may require root access so use sudo if need be.
