Hi,

I'm trying to get broadcasts to work.

Situation:

stratum 1 server 192.168.64.80
------------------------------
driftfile /var/lib/ntp/ntp.drift

server ntp.nmi.nl prefer
peer timekast2 iburst prefer
peer timekast3 iburst prefer
peer timekast4 iburst prefer

server 127.127.22.0 minpoll 4 maxpoll 4 flag2 1
fudge 127.127.22.0  refid PPS

restrict -4 default kod notrap nomodify nopeer
restrict -6 default kod notrap nomodify nopeer

restrict 127.0.0.1
restrict ::1

disable auth
broadcastclient

broadcast 192.168.64.255
broadcast 224.0.1.1


client 192.168.64.150
---------------------
driftfile /var/lib/ntp/ntp.drift

restrict -4 default kod notrap nomodify nopeer
restrict -6 default kod notrap nomodify nopeer

restrict 127.0.0.1
restrict ::1

disable auth
broadcastclient



Resulting in:
------------
received at client:
21:40:17.604135 IP 192.168.64.80.123 > 192.168.64.255.123: NTPv4, Broadcast, length 48

client ntpq -c pe -n:
root at bachinabox:/home/folkert# ntpq -c pe -n
No association ID's returned


So I wonder: what am I doing wrong? what could be the cause?
