Setup Your Linux Box as an NTP Server
I believe that every organization should have a NTP/time server if they have more than one computer on site. Having an NTP server will allow you to keep the times on all of your computers in sync. This helps when comparing the logs from various servers to trace through various events that happened. It’s nice to be assured that the event really happened at the time specified in the log file regardless of what server you’re on.
In this post I will show you how to setup your RedHat Linux AS 3 or 4 machine as an NTP server. You could then take all of your other servers and workstations and have them synchronize their time from your NTP server.
By default, the files necessary to run the ntpd service are installed on a RedHat machine if you installed everything.
