cation in the broadcast/multicast mode, and you must know which of the trusted keys it is using for
broadcast/multicast operation. The example Sonoma configuration shown in
Configuring the NTP
Server above will be assumed in the example configuration commands shown here.
• You have installed NTP on your client computer.
• You have successfully performed the Unix-like Platforms: MD5 Authenticated NTP Client Setup
on your client computer, if you plan to use MD5 authentication.
Configure NTP Client for Broadcast
You must edit the
ntp.conf
file which
ntpd
, the NTP daemon, looks for by default in the
/etc
direc-
tory. Assuming that your Sonoma server has been configured to use key 2 for broadcast authentica-
tion 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 file:
broadcastclient
If you are not using MD5 authentication, you would add these lines:
disable auth
broadcastclient
You may remove the line added previously in
Unix-like Platforms: Basic NTP Client Setup
:
server 192.168.1.120
or the authenticated version added in Unix-like Platforms: MD5 Authenticated NTP Client Setup :
server 192.168.1.120 key 1
Configure NTP Client for Multicast
You must edit the
ntp.conf
file which
ntpd
, the NTP daemon, looks for by default in the the
/etc
directory. And add these lines for multicast:
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
