How do I setup a "KA-Pi"?

3 - Download the "KA-Pi" image.

Think of the image as an exact copy of the whole hard drive of your PC or Mac, everything in just one file. In this case you will use this "image" file to then burn it, or write it, to your own SD card, making so an exact clone of an original KA-Pi server SD card I have with me. You are going to download it by FTP:

• FTP connection: Host = ftp.mujica.org , Username = anonymous@mujica.org, Password: anonymous, port = 21 (default).

Example: FTP download on Windows:

A very good and free FTP client for Windows, Mac and Linux is FileZilla ( filezilla-project.org). It has very important features (Keep-alive, auto reconnect) for downloading very large files like this.

Sample FTP login using FileZilla:

 

Once connected you'll see the files in the server available for FTP download. Go to the "pi" folder and drag the kaos_pi_16_20130921.img file to a folder in your computer. Example using FileZilla on Windows:

 

 

The FTP download will start.

 

Linux Example: FTP command line download:

 

 

Download from Linux using wget. Example:

wget ftp://anonymous%40mujica.org:anonymous@ftp.mujica.org/pi/kaos_pi_16_20130921.img

 

 

 

WARNING: This is a very large file, which may take a very long time to download, even hours if you don't have a fast Internet connection.

 

Important: if you want to verify the integrity of this very large downloaded file, which is strongly recommended to make sure that it has arrived intact during the long download process, this is the file md5 checksum:

• For the kaos_pi_16_20130921.img file: 7778f4caa756897f2044d4ba44820cc3

To verify if the MD5 checksum of the downloaded file matches the checksum of the original file (listed above) you can use on Windows a free tool like WinMD5Free (www.winmd5.com). Sample screenshot:

 

 

On Linux/UNIX you can just run the md5sum command, like: $ md5sum kaos_pi_16_20130921.img

 

4 - Write the downloaded KA-Pi image to your SDHC memory card.

This is what you need to do (example on Windows):

• Download Win32DiskImager, a free Windows software, from http://sourceforge.net/projects/win32diskimager/files/latest/download
• Unzip it and install it in your PC/laptop.
• Plug your SD card into your PC.
• Start the Win32DIskImager software (Win32DiskImager.exe)
• Select the downloaded ka_pi.img file and the drive where the SD card is inserted. Then click the "Write" button:

 

Now you have a card with the OS and the pre-configured KA-Pi package ready for action.

 

5 - Setup your KA-Pi server.

• Insert the SD card into the Raspberry Pi slot
• With the Raspberry Pi already plugged to your network or wireless router start the Pi, just plugging the power (If you want to login to this KA-Pi distribution please use username: pi , password: rachel . Of course you can change the password afterwards to anything you want..).

Sample setup with a $45 consumer wireless router:

 

• Find out the IP address of the Raspberry Pi:
• If you plug a TV to the Pi via an HDMI cable or composite cable you'll see the IP address at the bottom of the boot messages on the screen.
• Or from a terminal on the pi use the ifconfig command:

pi@raspberrypi ~ $ ifconfig
eth0      Link encap:Ethernet  HWaddr b8:27:eb:ce:67:31
          inet addr:10.0.1.20  Bcast:10.0.1.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

The IP address in the example above is 10.0.1.20
• If you have the Pi plugged to the router you can use another computer or device connected to the same network to see what IP address the Pi was assigned.
  For instance you can just you a phone connected to the same wi-fi network and use an app to scan it and find out the connected computers. The one which vendor name is "Raspberry Pi Foundation" is your Raspberry Pi. Make note of the IP address, 10.0.1.20 in this example. (Using the Scany iPhone app for this screenshot on the right).
• You can also use the router interface to find our the connected devices and get the IP from there.
• Note: later, if you use this solution in a semi-permanent setup, like in a school, you can assign in the router a static IP to the KA-Pi server, so the IP will be always the same, and the users/students can just bookmark it in their browsers.
