Plugin is working but
by nishith, December 31, 2019

Below are the simple steps that I've performed: 1) Downloaded the plugin in "/usr/local/nagios/libexec" directory. 2) chmod +x /usr/local/nagios/libexec/nagios_ntp.sh 3) RUN: /usr/local/nagios/libexec/nagios_ntp.sh RESULT: It is giving output as; NTP OK - Server: 5.103.139.163 Offset: 0.965 Jitter: 0.470; | Offset=0.965ms;10;20 Jitter=0.470ms;; The plugin works well but would like to know where this IP Address "5.103.139.163" comes from? I'm from INDIA & local NTP Server is "in.pool.ntp.org" only. I just want to check my NTP Service/Server is listeninig on port 123 or not. That's it.
