Test Broadcast/Multicast
Restart
ntpd
to have it begin using the Sonoma as a broadcast or multicast server. Use the NTP util-
ity
ntpq
to check that
ntpd
is able to communicate with the Sonoma. After issuing the command
ntpq
you will see the
ntpq
command prompt:
ntpq>
Use the command
peers
to display the NTP peers which your computer is using. One of them should be the Sonoma server
which you have just configured. You should verify that it is being ‘reached’. (You may have to con-
tinue issuing the peers command for a minute or two before you will see the ‘reach’ count increment.)
If you are using authentication, you can verify that authentication is being used by issuing the com-
mand
associations
to display the characteristics of the client server associations. In the “auth” column of the display,
you should see “OK” for the row corresponding to the Sonoma server. If you see “bad”, you should
wait a few minutes to be sure that there is a problem since “bad” is the initial state of this setting. If
the “bad” indication persists then you must check your configuration for errors. Typically this is due
to a typing error in creating the /etc/ntp.keys file on the client that causes a mismatch 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.
