1. First check if ntp can set the date from a remote server
$ ntpdate 0.north-america.pool.ntp.org
8 May 08:16:57 ntpdate[77470]: adjust time server 24.130.207.189 offset
-0.018950 sec
2. If you can then setup a basic ntp.conf
server 0.north-america.pool.ntp.org
server 1.north-america.pool.ntp.org
server 2.north-america.pool.ntp.org
server 3.north-america.pool.ntp.org
driftfile /etc/ntp.drift
3. Then start ntpd
# ntpd -c /etc/ntp.conf -p /var/run/ntpd.pid
Check the process table to see if it running, and check your messages file
for errors. On FreeBSD there will be a startup message in the log.
May 8 08:20:37 test3 ntpd[77481]: ntpd 4.2.0-a Thu Nov 3 07:34:18 UTC 2005
(1)
4. If its running run ntpq to see its status
# ntpq -p
remote refid st t when poll reach delay offset
jitter
