Configure NTP
Directory path names are not given in the instructions below because there are multiple ways to
install ntpd and multiple versions of Windows.
After installing ntpd, you must edit the ntp.conf le by adding a line similar to this:
server 192.168.1.120
This line tells ntpd.exe to use the NTP server at address 192.168.1.120 in addition to any other
servers which might also be congured in the ntp.conf le.
Restart ntpd.exe to have it begin using the Sonoma server. By default, the NTP installation pro-
gram installs ntpd.exe as a service called Network Time Protocol, and starts it. You must use the
Services utility in Control Panel to stop the Network Time Protocol service and then restart it.
Use the NTP utility ntpq.exe to check that ntpd.exe is able to communicate with the Sonoma.
From a console window, after issuing the command
ntpq
you will see the ntpq.exe 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 congured. You should verify that it is being ‘reached’. (You may have to
continue issuing the peers command for a minute or two before you will see the ‘reach’ count incre-
ment.) If you have other peers congured, verify that the offset information for the Sonoma server
peer and your other peers is in agreement to within a few milliseconds, assuming that the other peers
are synchronized to that level of accuracy.
It may also be useful to start the NTP daemon in ‘debug’ mode (ntpd -d) to conrm successful con-
guration. Refer to the NTP documentation for detailed usage of these debug utilities.
Windows: MD5 Authenticated NTP Client Setup
MD5 authenticated setup is relatively simple, if:
• You have been able to successfully communicate with the Sonoma on your network.
• Your Sonoma has been congured to perform authentication either by factory default, or by
running the ntpconfig shell script. The example Sonoma authentication conguration shown in
