Raspberry Pi Tutorial 2
Date: 2/20/2014
1. John Mosser will demonstrate a motion sensor using a Raspberry Pi.
2. Alain Tschanz will demonstrate how to access and monitor your
Raspberry Pi from anywhere in the world via the Internet.
Tutorial 2:
The second Raspberry Pi tutorial will cover the recommended
Raspberry Pi operating system called “Raspbian.” We will learn how to
update the RasberryPi firmware, the operating system and how to
install additional software from an external software repository.

Remote Access to Raspberry Pi
Method 1: SSH (Secure Connection)
- Home router configured to accept SSH traffic
- Raspberry Pi: SSH enabled
- Know your router’s Internet IP address (To find your routers
Internet IP address, go to http://ip-lookup.net/)
- Have SSH client installed (for ex. Putty) on computer
- Command to run:
[email protected] $ > ssh <username>@<host>
For example: > ssh [email protected]

Method 2: RaspCTL is an
application that lets you
control you Raspberry
Pi through a web
URL: http://raspctl.com/
To access your Raspberry Pi,
go to:
(8086 is the default port)
Remote Monitoring Raspberry Pi
Method 1: Rpi-Monitor
Access your Raspberry Pi via a
web browser or a phone*:

Upgrade Raspberry Pi Firmware
• [email protected] $ > sudo apt-get install rpi-update
[email protected] $ > wget http://goo.gl/1BOfJ -O /usr/bin/rpiupdate && sudo chmod +x /usr/bin/rpi-update
Note: If wget is not installed run the following command:
[email protected] $ > sudo apt-get install wget
Update and Upgrade Raspbian
Step 1: Update the repositories
[email protected] $ > sudo apt-get update
Step 2: Upgrade the packages
[email protected] $ > sudo apt-get upgrade
Installing and Uninstalling Software
Step 1: Search for the package
[email protected] $ > sudo apt-cache search xeyes
Step 2: Install a package
[email protected] $ > sudo apt-get install tuxeyes
To verify installation, run this command: [email protected] $ > tuxeyes
Step 3: Uninistall a package
[email protected] $ > sudo apt-get remove tuxeyes
To verify removal of software, run this command: [email protected] $ > tuxeyes
Basic Command line Commands
