I just recently added a pfSense router running a local ntp server and I'm seeing a lot of ntpd entries in my system log that i haven't noticed before-

Tried Google but didn't really find any answers. Not sure if this indicates some problem or just normal activity. Haven't seen any issues yet with time settings. Full diagnostics is attached just in case it's helpful.

By default ntpd will listen on all available interfaces, there is nothing wrong with that though not really needed.

 

unRAID 6.4 limits ntpd listening to the loopback and main interfaces only.

Thanks. Guess I just never noticed so many interfaces.
