Installing and Config GNS3 on Windows 7  PDF Guide for GNS3 installation: Download GNS3 PDF guide     Before learning how to install the Graphic Network Simulator or GNS3 on a computer, it is important to understand what the application is, how it works, and where it can be used. GNS3 is a GUI-based software application that is used by most networking scholars and network professionals to learn and establish Cisco-based network topologies in a virtual environment. In other words, GNS3 can be compared to VMware Workstation or Microsoft Virtual PC with the difference that in these 2 scholars and administrators can create and use the virtual machines having Windows, Mac, or Linux as guest operating systems, whereas in the GNS3 they can create and use virtual routers. Virtual routers created and configured in the application can be mapped with the physical NIC (the LAN card on the host computer) so that the virtual router topology can interact with the physical

Step 1: The first thing you should do is head to http://www.ubuntu.com/download/ubuntu/download and download Ubuntu 11.10 LiveCD. Just click the big orange Start download box. Step 2: Using your disc burning software, burn the .iso you downloaded to a CD. Step 3: Before you go any further, ensure all important data is backed up in case of data loss on your drives. This guide assumes you have media backups of your Windows partitioned hard drive and you are safe to proceed. ***Warning: Installing another operating system without first ensuring you have backups of your current files and operating system is a big risk. If you have no data to lose or you’ve backed up important data, you’re ready to proceed. YOU are responsible if you lose data.For those of you using Windows, and installing Linux for the first time I recommend you either use a separate hard disk that does not contain the Windows OS, or create a partition big enough for Linux within Windows using Disk Management in

Steps 1 Download the live image from the fedoraproject website. If you are a KDE Fan, go here . 2 Burn the . iso image to a CD, DVD or a USB stick. Make sure that you write it at a slow speed so that nothing gets broken in the process. 3 Change the BIOS settings. If you are using a live USB, you might need to go into your BIOS and change the boot priority in order to boot from your USB. You can access your computer's BIOS by pressing ‘F2’ or ‘Delete’ on most computers when the computer is booting up. If you are using a CD or DVD, ignore this step as generally CDs are first in boot priority. 4 Be sure to select "Live Drive" when the option screen first appears. If you select to install it, it can potentially delete everything from your system. 5 Explore the system. The most notable thing about you should toy with is the window manager which allows you to see pretty cool effects. You should also explore around the applications already installed in the OS

#1 Dual-boot Windows 7 and Kali Linux This article is a step-by-step guide on how to dual-boot Windows 7 and Kali Linux on a single hard disk drive (HDD). Kali Linux is what used to be BackTrack Linux, a distribution designed for penetration testing and security professionals. It ships with about 300 penetration testing and hacking applications installed. While BackTrack is based on Ubuntu, Kali Linux is based on Debian, and uses the complete Debian Installer. As a result, the installation process is different from that of BackTrack, which uses Ubuntu’s graphical installation program. The objective here is to show how to install it on an HDD alongside an existing installation of Windows 7, with the Windows 7 boot manager as the “master” boot loader, so that at the end, when the computer is (re)booted, you will be presented with a boot menu that looks just like the one shown below. Selecting Windows 7 boots the system into Windows 7 and choosing Kali Linux will, by default,
