Procedure
1. Log on to the SMW as root.
2. Stop the NTP server by issuing the
systemctl stop ntpd
command.
smw:~ #
systemctl stop ntpd
3. Edit the
/etc/ntp.conf
file on the SMW to point to the new server.
4. Update the clocks
smw:~ #
ntpdate timeserver
5. Restart the NTP server by issuing the
systemctl start ntpd
command:
smw:~ #
systemctl start ntpd
The SMW can continue to update the rest of the system by proxy. By default, the SMW qualifies as a stratum
3 (local) NTP server. For more information about NTP, refer to the Linux documentation.
6. Sync the hardware clock
smw:~ #
hwclock --systohc
7. Verify that the SMW has jitter from the NTP server
smw:~ #
ntpq -p
