I've tracked down a bug that prevents sending requests.  With no requests 
going out, there are no answers coming back.  A simple peers display can't 
distinguish that case from things like a dead server or bogus filtering.

ntpq doesn't have any easy way to display the underlying condition.  (or I 
haven't looked in the right place)

I think it only happens for IPv6 addresses and it may need something like 
stepping time to trigger it.

I'll have a fix out after some more testing.

These are my opinions.  I hate spam.
