If you are new to networking the graphical configuration tool is your best method for configuring new hardware in Ubuntu.We are going to use GUI tool “network-admin” to configure networking. Remember, you must be root to run network-admin.
There are two ways to start network-admin first thing is you can use your terminal to type “sudo network-admin” it will start up or you can go to System—>Administration —>Networking
Once it opens you should see the following screen

Building House with Box Modeling Using 3DSMAX 7
Hello everyone!
here we will try to build a old looking building which is intended pretty simple modeling method, specially designed for beginners and intermediate user can read it too, box modeling is one of old and common method of modelers and its still powerful method to model something inside any 3d package, when I was learning 3ds max after spending some time my teacher told me to model human figure he made the reference /images and asked me to start modeling, believe me it was my first attempt to model something and before this I never been done any thing, I start working and I was really confused I tried several methods no success, even I tried every thing and idea I had in my mind but still no success, in the meanwhile my teacher visited me and told a few steps and I start working again this time I was surprised of my speed, in few minutes I reached to her torso, and its called box modeling, I hope I am not talking too much sorry guys.
before starting the tutorial I would like to mention, this tutorial is dedicated to www.3dkingdom.org one of my favorite websites in (Computer Graphics).
ok guys lets start the lesson

How To Set Up A Linux Network For DEBIAN 4.0
Before we get into setting up Linux networking on a Debian system, we'll cover the basics of how to set up a network with both Windows and Linux systems and how to make it a "private" network. Here the term "private" may not mean what you think it does. It has to do with the IP addresses you use on your home or business network. You'll then understand the value of having a proxy/NAT server or a firewall system which also performs the proxy/NAT function on your network.
Once we cover the "whys" and "whats" we'll get into the "hows". You'll see how easy it is to set up a home or small-business network including what hardware is needed. We'll briefly mention what you need to look at on Windows PCs and present more in-depth information on which files are used on a Debian system to set up networking. The Network Configuration Files section shows what files are involved in setting up your Debian system to work on a local network and how they need to be configured to enable the various functions involved in networking including being able to connect to the Internet.
Note: Even if you're not familier with TCP/IP networks, try giving the material on this page a shot. It's presented in an introductory manner. Don't be concerned if you don't understand all of the material on OSI layers, subnetting, etc. presented on this page. Understanding this material is not necessary when setting up a network or using the subsequent guide pages on this site. It is merely presented for those who wish more in-depth information.
Even if you don't have a network you can still play around with the material present on this page and on the Proxy/NAT and Firewall pages. See the No-Network Network section below on how to do this.
What's particularly appealing about Linux for small businesses and non-profit organizations is that you can set up both internal (file, print, database) servers, external Internet (Web, e-mail, ftp) servers, firewalls, and routers (yes, you can set up a Linux system to be a router too) for very little cost. The operating system and server applications are free and, given that Debian will run on older hardware, the hardware costs can be minimal. These attributes also make it a great toy for those wishing to learn more about networking. Pick up one CD set and you can set up all the Linux servers, firewalls, and routers you want and experiment your brains out.

Introduction to Computer Networks
What can a Network do For You?
Introduction
A computer network can be two computers connected:
B.computer network can also consist of, and is usually made for, more than two computers:
Characteristics of a Computer Network
The primary purpose of a computer network is to share resources:
* You can play a CD music from one computer while sitting on another computer
* You may have a computer with a CD writer or a backup system but the other computer doesn’t have it; In this case, you can burn CDs or make backups on a computer that has one of these but using data from a computer that doesn’t have a CD writer or a backup system
* You may have a computer that doesn’t have a DVD player. In this case, you can place a movie DVD on the computer that has a DVD player, and then view the movie on a computer that lacks a DVD player
* You can connect a printer (or a scanner, or a fax machine) to one computer and let other computers of the network print (or scan, or fax) to that printer (or scanner, or fax machine)
* You can place a CD with pictures on one computer and let other computers access those pictures
* You can create files and store them in one computer, then access those files from the other computer(s) connected to it
