CHAPTER Installing a base operating 3 system INFORMATIONINTHISCHAPTER: • Available operating systems for the Beagles • Attributes of a penetration testing Linux distribution • Ubuntu options • New kernel changes • Device trees • Creating a microSD card for your Beagle INTRODUCTION As we learned in the last chapter, the BeagleBoard.org has been shipping open hardware boards since 2008. In this chapter, we will briefly examine some of the operating system options listed at the BeagleBoard.org website. Once we have a feel for what is available, we will talk about what makes a good penetration testing Linux distribution. After selecting an appropriate base operating system, we will discuss particulars and how recent kernel changes affect our decision. Finally, we will conclude this chapter by detailing the procedure for creating a microSD card to house our chosen operating system on our Beagles. NON-Linux OPTIONS Time for a little honesty. Given that we are looking to have some hacking fun and build something for penetration testing, we are fairly certain we will end up with some version of Linux. That said, I wanted to briefly present some non-Linux options available for the Beagles for completeness and to demonstrate the versatility of these boards. Windows CE You might be thinking you can’t run a proprietary operating system on open hardware, but in this case, you can. Given that the BeagleBoard-xM and BeagleBone Black have more computing power than many systems running Windows XP, you might wonder why not run a more full version of Windows than Windows CE (commonly known as WinCE and officially renamed to Windows Embedded Compact). The answer is that Windows CE runs on ARM systems with board support packages Hacking and Penetration Testing with Low Power Devices © 2015 Elsevier Inc. All rights reserved. 27
28 CHAPTER 3 Installing a base operating system (BSPs), while desktop versions of Windows are not ARM-compatible. Adeneo used the unified BSP supplied by Texas Instruments as a base in order to create a BSP for the BeagleBoard-xM (http://www.adeneo-embedded.com/en/Products/Board- Support-Packages/BeagleBoard). Based on comments at the BeagleBoard.org site, people prefer to run something else on the Beagles (http://beagleboard.org/pro ject/WinCE7+BSP+for+BeagleBoard-XM/). Windows CE running on a Beagle- Bone Black with a seven inch Chipsee touchscreen cape is shown in Figure 3.1. QNX The QNX Neutrino Real Time Operating System (RTOS) is available for Beagle family of devices (http://www.qnx.com/products/neutrino-rtos/neutrino-rtos.html). Real-time operating systems are used in embedded devices where the system response time must be deterministic and as short as possible. A typical RTOS is lightweight and tightly integrated with hardware via support for interrupts and timers. The QNX RTOS features a microkernel design. The company provides a few reference designs to demonstrate the capabilities of QNX Neutrino (http://www.qnx.com/ products/reference-design/ti-reference-design.html). The QNX smart energy reference design running on a BeagleBoard is shown in Figure 3.2. FreeBSD FreeBSD is based on the Berkeley Software Distribution (BSD) version of UNIX. Linux is based System V (SysV) UNIX, the other major branch of UNIX. The two flavors of UNIX are just different enough to cause users a bit of grief.
