Every machine on the the Internet has a unique number assigned to it, called an IP address. Without a unique IP address on your machine, you will not be able to communicate with other devices, users, and computers on the Internet. You can look at your IP address as if it were a telephone number, each one being unique and used to identify a way to reach you and only you.
The Address Itself
An IP address always consists of 4 numbers seperated by periods, with the numbers having a possible range of 0 through 255. An example of how an ip address appears is: 192.168.1.10
MRTG(The Multi Router Traffic Grapher) will monitor SNMP network devices and draw pretty pictures showing how much traffic has passed through each interface.
Installing packages
Webmin is a web-based interface for system administration for Unix. Using any modern web browser, you can setup user accounts, Apache, DNS, file sharing and much more. Webmin removes the need to manually edit Unix configuration files like /etc/passwd, and lets you manage a system from the console or remotely.
You can install webmin for your server web interface to configure apache,mysql servers.Now we will see how to install webmin in Ubuntu 8.04
I prefer to use VirtualBox rather than VMware as it seems to be rather faster and less resource hungry than VMware Server (the only free version of VMware with a GUI). Also VirtualBox seems to have better Linux host support (sound, etc.). However, there is one thing that VMware is better at - setting up the guest network on the same network as the host. Under VirtualBox this is called “Host Interface Networking” and, with a Linux host anyway, is a right royal pain to set up. This is because VirtualBox uses the powerful and flexible bridging capabilities of Linux - but they have no easy GUI setup!
Another approach is to add a Google AdSense banner on top of every module. You can include the AdSense Javascript code in a separate file, call it adsense.php, and then just include this file from your module, as we did for the News sections above.
