Setting up the NTP time sync service on PurdData for Analytics

Troubleshooting


Problem

How do I set up the NTP time sync service on my N100x N200x N300x appliance?

Resolving The Problem

1. In a text editor, like vi, open the file /etc/ntp.conf for editing and comment out the current server and fudge lines. This will need to be applied to both hosts.
2. Add the following line to the file, specifying the IP address of your NTP time server:

server ipAddress

Alternatively, you can use one of the public Internet time servers listed at NTP.Servers Web.

3. Save and close the /etc/ntp.conf file.
4. Once you've added the server IP address to /etc/ntp.conf, run the following commands:
/etc/init.d/ntpd stop
/etc/init.d/ntpd start

5. You should be synchronized shortly thereafter. To confirm this, wait approximately 30 minutes and run the following command:

/usr/sbin/ntpq -p

The output should be similar to the following, listing the new remote server:

[root@netezzan ~]# /usr/sbin/ntpq -p
