I have Raspberry Pi Model-B with the Raspbian Wheezy OS and a local NTP server. I want to synchronise my Raspberry Pi board with my local NTP server (not using the Internet). All the process must be offline, not using the Internet.
What is the step-by-step process to do this? How can I add my server's IP address?
This answer is OBSOLETE. Debian 9 uses
systemd-timesyncd.service
In /etc/ntpd.conf, replace the existing "server" entries with one for your server. You can use the hostname or IP address of your server.
For example:
server 192.168.1.15
After changing the file,
sudo service ntp restart
will restart the NTP daemon using your updated configuration.
Use
$ sudo ntpq
ntpq> peers
to verify that it's using your host as a peer. If everything is working, you should see non-zero values in the "when" and "reach" columns.
