This document discusses virtualizing networks using VirtualBox and Leonidas virtual machines. It provides instructions on downloading VirtualBox, copying the Leonidas virtual drive image, and installing necessary software onto a master Leonidas image that can then be cloned to create duplicate virtual machines easily. Various terms related to virtualization and virtual machines are defined. Potential practical applications of virtual machines like learning Linux, security testing, and networking are described. The document demonstrates configuring internal networking between cloned virtual machines in VirtualBox.

1. Virtualizing Networks for Fun and Profit Matt Maisel Brian Reitz

2. Download VirtualBox and Leonidas VDI http://www.virtualbox.org/wiki/Downloads Copy Leonidas virtual drive image onto your desktop from a flash drive

3. The 300 LEONIDAS Solution A product of SRA 221, Fall 2008

4. Leonidas InfoSec, LLC Executive Level Leadership

5. Malicious Attackers, Tonight You Dine in Hell!

6. Virtualize the Network with Leonidas Clones

8. Leonidas Fights for the Future of the Free Enterprise Virtualization will move processing power back to the mainframe Virtualization redefines rapid development and disaster recovery Virtualization makes baseline management easy Open Source software is coming to a level of maturity

9. The Cogs of Leonidas Technical Implementation

10. VirtualBox VirtualBox is free, open-source virtualization software developed by Sun, Inc. It creates virtual machines upon which nearly any operating system can be run. Users can customize the amount of RAM, hard drive size, network adapters, etc. as needed. http://virtualbox.org

11. Ubuntu 7.10 Ubuntu is a distribution of Linux that focuses on ease of use, compatibility, and security. Ubuntu 7.10, released in October of 2007, was the operating system detailed in the project outline provided and has since been superseded by Ubuntu 8.10, the Intrepid Ibex. http://ubuntu.com

12. Synaptic Package Manager The APT framework Makes installing popular packages as simple as sudo apt-get install openssh Manages updates and dependencies as well http://wiki.debian.org/Apt

13. The Master Image Install all the necessary software onto a master leonidas. Use Vboxmanage to clone the hard drive image, essentially making duplicate machines. Easy to simulate back-ups. Spend less time installing and configuring software

14. Definitions and terms SRA Club? What’s that mean?

15. Virtualization The abstraction of computer resources Platform Virtualization Virtualization of computers or operating systems. It hides the physical characteristics of computing platform from the users, instead showing another abstract, emulated computing platform.

16. Cloud Computing Internet, "cloud," based development and use of computer technology that provides real-time scalable resources are provided “as a service” over the Internet to users who need not have knowledge of, expertise in, or control over the technology infrastructure that supports them. Google Apps Salesforce.com, Amazon Web Services

17. Host In this context, we’ll use host to refer to the physical computer running the virtual machines, to keep things straight. A host can virtualize one or more virtual machines.

18. Commandline A mechanism for interacting with a computer operating system or software by typing commands to perform specific tasks.

19. Virtualization software VirtualBox Xen VMWare VMWare Server VMWare ESX VMWare Workstation Parallels Desktop for Mac QEMU Microsoft Virtual Server Microsoft Virtual PC

20. VMWare vs. Virtualbox Free, open-source, limited vs free, licensed, and limited?

21. VMWare Appliances Virtual Appliances are pre-built software solutions, comprised of one or more Virtual Machines that are packaged, updated, maintained and managed as a unit. Unlike a traditional hardware appliance, these software appliances let customers easily acquire, deploy and manage, pre-integrated solution stacks. This speeds up time to value and simplifies software development, distribution, and management.

22. Virtualbox and Vboxmanage If you are comfortable with the command line, you can do something similar by duplicating the .vdi, the virtual machine’s hard drive, and creating a new machine. This is the route we took.

23. Which is better? Virtualbox Open-source (partly) Free for personal use Easy to set up Cloned virtual machines can be tuned as needed -Some capabilities require the command-line Networking can be tricky VMWare Many different versions Some are free (Server, Player) Registration is needed for some Appliances can’t be tweaked Appliance Marketplace Easier VM networking Verdict: Hard to say

24. Practical Applications Why bother with virtual machines?

25. 1. Learning Linux without fear Don’t worry about hardware requirements Automatically set up internet access, too! Keep your current operating system Try out different operating systems Use only the tools you need Easily recover from catastrophic failure The infamous “rm –rf /”

26. 2. Try some hacking! Perfectly legal to hack your own (virtualized) computer Damn Vulnerable Linux [http://damnvulnerablelinux.org] Proof of concept exploits and attacks See how fast an unpatched copy of Windows can get exploited. Don’t forget the MSDN Academic Alliance! Brute-force attacks

27. 3. Learn some networking! Equipment is expensive! Easily try differences between OS’s *nix systems: ifconfig Windows systems: ipconfig Because it’s virtual, you can pull it up anytime you need it in minutes. Much more convenient than trying to get in the networking lab.

28. 4. Great for in-class demos

29. Real world implementations Virtual Private Server Hosting Ex: linode.com, slicehost.com Pay for more resources/bandwidth If you screw up big time/get haxxed, just reset the VPS Enterprise systems Legacy systems Come see a speaker from Morgan Franklin on Monday February 2 in the Cybertorium!
