Configuration

Install xntp (btw I am sure you have already).

# rpm -ihv xntp-4.2.0a-46.i586.rpm

Edit /etc/ntp.conf

# Restrict NTP access in default

          restrict default ignore

          # Allow NTP access from localhost

          restrict 127.0.0.1

          # Allow access from LAN

          restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap

          # Allow access to external NTP servers

          restrict 210.173.160.57 mask 255.255.255.255 nomodify notrap noquery

          restrict 210.173.160.27 mask 255.255.255.255 nomodify notrap noquery

          # External NTP servers

          server 210.173.160.57

          server 210.173.160.27

          # CMOS clock

          server 127.127.1.0

          fudge 127.127.1.0 stratum 10

          # Drift file

          driftfile /var/lib/ntp/drift/ntp.drift

          # Alternate logfile

          logfile /var/log/ntp

Start ntpd

# chkconfig ntp on

          # /etc/init.d/ntp start

After sometime (more than 15 minutes), verify the ntp server

# ntpq -p
