Plugin is working but

by: nishith

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.
