I'm running a Unix server with NTPD version 4.2.7. I have various clients using this as its main NTP server such as other unix servers, cameras, IOT devices, etc. I want to get a list of which IPs are using this NTP server to find out which clients would be affected if this UX server went down. The below is what I get when running ntpdc -c monlist, not what I expected, expected information on clients using this as their NTP server.
server# ntpdc -c monlist ***Server reports data not found
Thank you all.
