For Purposes of this Discussion …• A “Complete” Computer• Small in Size (Credit Card) • Inexpensive < $100• Geared Toward Education• Large User Community• Relatively Easy to Use• Significant Teaching/Learning Materials• Significant 3rd Party Add-ons Accessories

About the BBB …

About the RPi …Note: In April Banana Pi, a more powerful Chinese clone was announce along with the HummingBoard.

The inside story of the Raspberry Pi

• SD Card 8GB (recommend class 10)• Keyboard & Mouse• Micro USB Power Supply• HDMI Cable• Display

Optional – Case

Getting Started – Hardware … (not quite a $45 computer)

3rd Party Bundles• 8 GB SD Card (Class 4) with NOOBS• Micro USB Power Supply• Case with GPIO Access• HDMI Cable• Breadboard• Jumper Cables, GPIO Interface/Ribbon• LEDs, Resistors, Switches

Storage, Connectivity and Printing Options …

Headless ConnectivityStorage

Printing

Getting Started – Software … (Raspbian)

• Format the SD card with SD Formatter 4.0 (sdcard.org)• Download & extract NOOBS (raspberrypi.org/downloads)• Copy extracted NOOBS files to the SD card• Put SD card in the RPi and plug in keyboard, mouse, and monitor• Plug in USB power to boot• Install Raspbian (and any other OSs you’d like) configure as prompted• Login username = pi password = raspberry• Load GUI with startx

Raspberry Pi Desktop – Raspbian (based on Debian) Linux with LXDE GUI

Raspberry Pi Software• Accessories• Education• Graphics• Internet• Programming• Sound & Video• System Tools

Note: The Advanced Packaging Tool (apt-get) can be used to install lots of software not included with NOOBS

General Purpose & Educational ApplicationsAccessories• Text Editors

• Nano (Terminal)

• Vim (Terminal)

• Leafpad (GUI)

• Image Viewer• LXTerminal• File Manager (GUI)

Internet• Midori• Other Browsers

Educational• Mathematica• Scratch• Sonic Pi

Why Use Single Board Computers?Student Benefits:• “Worry free” trial and error interaction with the device• Complete control over the device hardware & software• Low-level programming that wouldn’t be advisable on other platforms

Faculty Benefits:• Ability to configure special class distributions• More class time spent on teaching/learning rather than configuring

Programming Curriculum• Python (2.7 & 3)

• PyPy

• Wolfram

• Ruby

• Bash (and Dash)

• Squeak Smalltalk

• C (gcc)

• GDB GNU Debugger

• Java

• Perl

• C++ (g++)Many Others …

• MySQL

• Erlang

• APL

• TinyBASIC

Operating System CurriculumOperating Systems• Multiple Linux (Android, Arch,

Chromium, Debian, Firefox, etc.)• Unix (FreeBSD & NetBSD)• RISC• Windows CE• Plan 9 from Bell Labs• ChibiOS/RT

Sample Areas• Device Management• File Systems• Performance• Scheduling & Dispatch• Scripting• Security• Forensics• Server Services

Networking & Security CurriculumSoftware• Raspbian• Apache & Cherokee Webservers• Nmap (Zenmap)• Wireshark• Netcat• Iperf• NetHogs

Sample Areas• Protocols - TCP, DNS, SMTP, etc.• System Vulnerabilities• Techniques & Tools – Detection

& Defense• Security Principles – Sandboxing

& isolation• Attacks – DoS, DDoS, SQL

Injection, etc.

General Purpose Input Output (GPIO)

• Electronics• Adafruit Tutorials• OpenSprinkler

• Robotics• Udemy PiBot Course • FishPi

• Microprocessor & Board Control (ARMv6 Assembler)

Non-Academic HE Purposes• Security

• Penetration Testing (PwnPi)• Web Honey Pot (Glastopf Pi) (KippoPi)

• Small Server (Web) (BitTorrent) (FTP) (SFTP and Samba) (Web Cam)• Automation• Streaming Media (XBMC)• Digital Signage (Concerto Digital Signage from EDUCAUSE listserv)

Nefarious Purposes?Let’s face it. They’re small $35 - $45 (disposable) Linux computers with very low power consumption that can operate off of AA batteries and have WiFi/Ethernet capability!• Man-in-the-middle Attacks RPi running PwnPi Linux distribution• Tor Relay• Trojan Horse (Phoning Home Using a Reverse Remote Ssh Tunnel)• Wireless Sniffing (Kismet)• Limited Only to the Hackers Imagination ...
