NTP

CactiEZ – configuration basics

Every time I install CactiEZ or Cacti on another platform, I am searching for the commands to basically install the most common parameters, like static IP addressing, NTP sync and time zones.

Several times I thought about writing a simple article with the necessary commands and final I had time to create it.

Networking

netconfig
service network restart

Time Sync

ntpdate –u ntp1.nl.net

Time Zone

yum install system-config-date
system-config-date

This will make my life so much easier.

NTP Configuration

The right time synchronization is very important while troubleshooting different kind of problems. Most network components have the option to synchronize their time with a time server on the internal network or the internet. This post shows how to configure NTP with the right time zone on Cisco and HP ProCurve components. The example configurations use the NTP servers from pool.ntp.org.
