When you invoke the NTP client at the command line, use the following options:
– b
to turn on broadcast reception
– k /etc/ntp.keys
to specify the name and location of the keys file
– d
for debugging.
An example command line might look like:
ntpd –d –d –d –b –k /etc/ntp.keys
Important lines in the ntp.conf file of the ntp client (not server) are:
trusted key 1 2
If you do not use MD5 authentication, remove # from “#disable auth”.
