problem.) It is also possible to have a typing error in the /etc/ntp.conf file that causes the needed key
to not be included in the “trustedkey” list.
Unix-like Platforms: Broadcast/Multicast NTP Client Setup
Broadcast/multicast client setup is relatively simple, if:
• You have been able to successfully communicate with the Sonoma on your network.
• Your Sonoma has been configured to perform broadcasts or multicasts by running the
ntpconfig
shell script. (This is not the factory default configuration, so be sure to run
ntpconfig
.) If you are
going to use MD5 authentication, your Sonoma must have been configured to operate with authenti-
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:
