between the keys being used by the server and client. (If you transfer the file by
ftp
or
scp
, this
shouldn’t be a 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 Meridian II on your network.
• Your Meridian II has been configured to perform broadcasts or multicasts by running the
ntp-
config
shell script. (This is not the factory default configuration, so be sure to run
ntpconfig
.) If
you are going to use MD5 authentication, your Meridian II must have been configured to operate with
authentication in the broadcast/multicast mode, and you must know which of the trusted keys it is us-
ing for broadcast/multicast operation. The example Meridian II 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
directo-
ry. Assuming that your Meridian II 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:
