Thank you for the reply. ntpd will not sync with the broadcast server
unless I open the wildcard interface. So if my ntpd.conf file looks
server ******* minpoll 4 maxpoll 4 iburst burst
fudge ******* stratum 12 refid LCL
tinker panic 10
ntpd selects the local clock. In this state, I've already done a
tcpdump and can see the broadcast messages coming in. Additonally, I
can ping the broadcast servers. I've already checked for firewall
issues and there are none. Again, everything was functionally
correctly when running 4.2.0.
I have to add the following two lines to my .conf file for ntpd to
sync with the broadcast server:
interface listen wildcard
interface listen all
So in my situation, I have to listen on the wildcard interface in
order to sync with the broadcast server.
