Configuring NTP

Figure 4-4 shows the peer, server, and broadcast statements that are
configured for all the servers.
Figure 4-4 Example Configurations
You must configure the time server in the client system. For example, if
Penelope is a client for Bonita, you must configure the name or IP
address of Bonita on Penelope. You need not configure Penelope as a
client on Bonita.
Configuring a Driftfile
The xntpd daemon computes the clock frequency error for a local host,
and stores the frequency error in a driftfile. xntpd computes an
accurate estimate of the frequency error after running for one or more
days. When xntpd restarts, the driftfile allows xntpd to reinitiate itself
to the estimate stored in the driftfile; thus, helping xntpd to save time in
recomputing the frequency estimate. You can specify a name and path
for the driftfile.
NOTE xntpd must be running continuously; if you wish to stop xntpd, it must
be for a short duration.
You can use the following option to specify the driftfile:
Gordo
Penelope Golden
Hugo
server bonita
peer golden
broadcast 193.100.255.255
