y default, my ntpd/NTP server listens on all interfaces or IP address i.e 0.0.0.0:123. How do I make sure ntpd only listen on a specific IP address such as localhost or 192.168.1.1:123 on a Linux or FreeBSD Unix server?
‘ve setup an NTP (Network Time Protocol) client and/or server
to manage the system clock over a network. But, how do I verify that it is working correctly?
