Turn on service on boot:

# chkconfig ntpd on

Synchronize the system cloc

k with 0.pool.ntp.org server:

# ntpdate pool.ntp.org

Start the NTP:

# /etc/init.d/ntpd start

You can actually create these settings on our platform in few minutes utilizing our PCS (Private Cloud Solution) which allows you to have VPSie(s) on a private network – NAT – Port forward – traffic control for inbound and outbound – multiple gateway IPs which you could use for the load-balancing and failover.
