If you are not using MD5 authentication, you would add these lines:
disable auth
broadcastclient
You may remove the line added previously in Windows: Basic NTP Client Setup:
server 192.168.1.120
or the authenticated version added in Windows: MD5 Authenticated NTP Client Setup:
server 192.168.1.120 key 1
Configure NTP Client for Multicast
You must edit the ntp.conf le. Assuming that your Sonoma server has been congured to use key 2
for broadcast authentication as shown in the example in Configuring the NTP Server above, make
sure that key 2 is included in the trustedkey line, and add this line to the end of the ntp.conf le:
multicastclient 224.0.1.1
or for IPv6:
multicastclient ff05::101
If you are not using MD5 authentication, you would add these lines:
disable auth
multicastclient 224.0.1.1
or for IPv6:
disable auth
multicastclient ff05::101
You may remove the line added previously in Windows: Basic NTP Client Setup:
server 192.168.1.120
or the authenticated version added in Windows: MD5 Authenticated NTP Client Setup:
server 192.168.1.120 key 1
Test Broadcast/Multicast
Restart ntpd.exe to have it begin using the Sonoma as a broadcast or multicast server. By default,
the NTP installation program installs ntpd.exe as a service called Network Time Protocol, and starts
it. You must use the Services utility in Control Panel to stop the Network Time Protocol service and
then restart it.
Use the NTP utility ntpq.exe to check that ntpd.exe is able to communicate with the Sonoma.
After issuing the command
ntpq
