Several steps need to be taken to properly configure the NTP daemon.

1. First, create or update the file /etc/ntp.conf.  Several
   example configuration files can be found here:

     /usr/local/share/examples/ntp

2. Now xntpd can be started with:

     /etc/rc.d/xntpd start

   Or to start 'xntpd' at every boot, add it to pkg_scripts in
   /etc/rc.conf.local.

#vi /etc/rc.conf.local

Add as following :

pkg_scripts="xntpd"

Edit /etc/ntp.conf as following :

server 3.my.pool.ntp.org
server 0.asia.pool.ntp.org
server 3.asia.pool.ntp.org

This will affect on your next reboot. To start xntpd simply type :

#/etc/rc.d/xntpd start

Building a KVM Proxy

Traditionally we seldomly connect our KVM from the port directly to the server that consists of usb for keyboard and mouse, vga cable for display purposes. More advanced you may have an experience using the iKVM which connect all you kvm port from the internet where you can have a remote location as long as you have the internet connection. When technology evolve, physical server are becoming obsolete since we have the virtualization technology. Since that to access your virtual machine (vm) are more easier. Instead of using SSH, like a Xen hypervisor, the Xen itself can host as a KVM server and map to the vm on different port as configured from the config file.

Warning Nuffnanger's!

Dear Nuffnangers, As you might already know, there are 2 different types of campaigns from Nuffnang: Metered (mCPM) Campaigns , which pay according to the number of visitors who see the ads; and Cost-Per-Click (CPC) campaigns, which pay bloggers based on the number of clicks generated on the ads. It has come to our attention that certain groups have been committing click fraud, which is defined as clicking on CPC advertisements intentionally just to generate earnings for a blog's owner. Do note that this act is an abuse of our Terms & Conditions under Section 6. Banner ads are only supposed to be clicked on if the viewer is interested to find out more about the advertising campaign, and not for the intention of earning extra money. Should this situation worsen, the frequency of ad campaigns might be significantly reduced as we'll only be able to sell ad spaces on blogs with no click fraud record. Our system is capable of tracking these illegal actions...
