Fix Recommendation

The ntpdate service sets the local hardware clock by polling NTP servers when the system boots. It synchronizes to the NTP servers listed in "/etc/ntp/step-tickers" or "/etc/ntp.conf" and then sets the local hardware clock to the newly synchronized system time. The "ntpdate" service can be disabled with the following commands:

# chkconfig ntpdate off
# service ntpdate stop

Check Contents

To check that the "ntpdate" service is disabled in system boot configuration, run the following command:

# chkconfig "ntpdate" --list

Output should indicate the "ntpdate" service has either not been installed, or has been disabled at all runlevels, as shown in the example below:

# chkconfig "ntpdate" --list
"ntpdate" 0:off 1:off 2:off 3:off 4:off 5:off 6:off

Run the following command to verify "ntpdate" is disabled through current runtime configuration:

# service ntpdate status

If the service is disabled the command will return the following output:

ntpdate is stopped

If the service is running, this is a finding.
