Ensure that the service is enabled with:

chkconfig ntpd on

Ensure that if you have firewall enabled, you allow traffic to the ntp port.

Also, after a restart, will take some time before the NTP service is provided. Use the ntpq -pn command to identify when the NTP service is provided. You should see an "*" in front of an NTP server when NTP is ready.

Shalom,

ps -ef | grep ntp

Is there a process running.

If not:

Start it:

/etc/init.d/ntpd start

chkconfig ntpd on
# To set up auto start.

If you recently upgraded your configuration file may have been archived with the ending rpmsave or rpmnew. Check that.

Don't forget to tail your messages file for helpful info:

'tail -f /var/log/messages'

While doing the tail, restart ntp from a different terminal:

service ntpd restart

or

/etc/init.d/ntpd restart
