Walker News  Configure Linux NTP Time Synchronization Server In
A Minute  You may not care about time synchronization of a
personal computer, but it’s critical to most server
applications. Hence, server system administrators have to ensure
that NTP server is working at all time! NTP, or Network Time
Protocol, is a TCP/IP protocol used for time synchronization.
NTP client (such as ntpdate) synchronize system time with
designated NTP time servers (such as ntpd of Linux), which are
generally classified in stratum 1 and stratum 2. Stratum 1 NTP
server is using an atomic clock for precise timing, while
stratum 2 NTP server is using non-atomic clock that produce
slightly less accurate timing. NTP.org is generally a creditable
site for reference of public-available, Internet NTP time
servers of both stratum 1 and stratum 2.  Steps to setup Linux
NTP time synchronization  Should be applicable to Redhat,
Debian, Linux / UNIX alike. WalkerNews is a Linux machine in DMZ
segment, running ntpd to synchronize its system ti
