Here are the summaries to my NTP related questions:
(1). Do I need to build and install the NTP programs on the client
machines just like I did it on the server machine?
It depends. If you use UNIX command 'rdate' to sync the time, you don't
need ntp programs on the client machines. Otherwise you need them.
However, if all the machines run the same OS, you can just copy over the
binaries to the clients instead of rebuilding on each client.
(2). I'm confused about the configuration files (/etc/ntp.conf...),
Does somebody have sample files for both server and client
that is suitable for the Class C network?
Here are a very good example I got from the replies:
For the time server (called machine_0):
#server www.xxx.yyy.zzz # some external stratum 1 or stratum 2
#peer machine_1 # local peer (sync'ed to external stratum
#peer machine_2 # local peer (sync'ed to external stratum
server 127.127.1.0 # local clock
fudge 127.127.1.0 stratum 10 # keep local clock humble
For the client:
This tells them to look to "machine_0" for time service.
(3). Besides the NTP programs, do I need special hardware devices such as
modem, radio clock, GPS clock server..., etc to successfully
No. An internet connection is sufficient.
