Installation and Configuration

2Replace the defaults with your preferred time server. You can specify multiple time servers and use either IPv4 or IPv6 addresses. For example, the new section should look similar to the following:

#Use public servers from the pool.ntp.org project.

#Please consider joining the pool (http://www.pool.ntp.org/join.html). server 192.168.2.22

3Save and close the file.

4To set up the NTP daemon to start every time the server starts, at the command line, type: chkconfig ntpd on

Changes to the NTP settings do not take affect until you restart the NTP daemon or the entire server.

To restart the NTP daemon:

1At the command line, type: service ntpd restart

To check the time source connection status:

1At the command line, type: ntpq -p

The result of this command should be similar to the following:

remote

refid

st

t

when poll reach

delay

offset

jitter

The fields described in Table 11 can help you determine if there is a time sync problem.

Table 11 ntpq -p command output

Field

Description

remote

IP address of the NTP server.

st (stratum)

A stratum value of 16 indicates a time synchronization failure.

when

Number of seconds since the last poll. This value should be less than or equal to

 

the poll value. A “when” value that exceeds the “poll” value indicates a time sync

 

problem.

poll

Polling interval in seconds. The “poll” value will be greater than the “when” value

 

when the time server is synchronizing successfully.

jitter

A value of 4000.00 indicates a time synchronization failure.

 

 

The ETKMS server may initially report as unsynchronized. The synchronization may take several minutes. After multiple attempts, if the output of the ntpq -pcommand continues to indicate a time synchronization problem check the following:

●Verify that the NTP server IP address is a valid address

●If you are using a local NTP server, check to see if the NTP server is powered on

●Check for network problems that may prevent the ETKMS from reaching the NTP server
