NTP synchronization in Debian

[Super Moderator]

Install tzdata in order to set the proper timezone. (Check here for your correct time zone). Install ntp-date which acts as a client to the NTP server.

Code:

# apt-get install ntpdate tzdata

Set your system to the correct timezone and follow the screen to select

Code:

# dpkg-reconfigure tzdata

Current default timezone: ‘Etc/GMT-4′
Local time is now: Tue Mar 30 17:15:10 GMT-4 2010.
Universal Time is now: Tue Mar 30 13:15:10 UTC 2010.
Edit configuration file for ntpdate

Code:

# vi /etc/default/ntpdate

Use these minimal settings for the ntpdate configuration file

Quote:NTPDATE_USE_NTP_CONF=no
NTPSERVERS="IP Address or Hostname of the NTP server”
NTPOPTIONS=”"

Check the current time for reference

Code:

# date

Tue Mar 30 17:16:50 GMT-4 2010
Run ntpdate-debian to update the time with the NTP Server and check the time again to check if indeed the time is set.

Code:

# ntpdate-debian

30 Mar 15:08:45 ntpdate[16335]: step time server 192.168.1.10 offset -7698.937783 sec

Code:

# date

Tue Mar 30 15:08:47 GMT-4 2010
Include ntpdate in the cron jobs in order to have the client synchronize with NTP server every week.

Code:

#vi /etc/cron.weekly/ntpdate

Edit the file with these content:

Quote:#!/bin/bash
set -e
[ -x /usr/sbin/ntpdate-debian ] || exit 0
/usr/sbin/ntpdate-debian

Apply the correct file permission

Code:

# chmod 755 /etc/cron.weekly/ntpdate

It is important to understand that without proper time synchronization in the IT infrastructure, tracking security breaches, network utilization, or problems affecting a large number of devices can be nearly impossible if timestamps in logs are incorrect. Time is often the critical component that allows an event on one node on the network to be linked to a corresponding event on another.
