Setting up The Raspberry Pi


 Raspberry Pi 




Getting everything working on the Debian “squeeze” image debian6-19-04-2012.zip
To use an image file, you will need to unzip it and write it to a suitable SD card using the UNIX tool dd. Windows users should use Win32DiskImager. Do not try to drag and drop or otherwise copy over the image without using dd or Win32DiskImager – it won’t work. If you’re still not clear on what to do, the community on the Raspberry Pi Wiki has written a guide for beginners on how to set up your SD card. Minimum size 2GB, if bigger than 2GB watch this http://www.youtube.com/watch?v=DztSRaFyaVE
on how to resize the image to use all of the sd card.
login pi
Password raspberry

First change your password
Type passwd , then when it asks for current password type raspberry and hit enter (you wont see any text or * on screen when typing the password).
Now enter your new password, hit enter, next re-enter your password to confirm and hit enter.
All the flowing commands work like this: command followed by hitting enter, each new line is a new command.


How to get ssh working
sudo bash
ssh-keygen -t rsa
sudo mv /boot/boot_enable_ssh.rc /boot/boot.rc
ifconfig -a (to get your Raspberry pi's ip address)
If that didn't work  try this:  sudo /etc/init.d/ssh start 
Now you can shh into your Raspberry pi from any other computer on the same network. In Ubuntu its as simple as opening terminal and typing ssh username@yourip, press enter and then enter your password. Now you can cut and paste commands to save time typing.
If you want to know more about ssh Hak5 are doing some really good videos all about ssh and proxies starting with episode 1108 season 11 Hak5 1108 – Hak5 Special: Proxies – Part 1


Updating Everything
sudo apt-get update
sudo apt-get install ca-certificates
sudo wget http://goo.gl/1BOfJ -O /usr/bin/rpi-update
sudo chmod +x /usr/bin/rpi-update
sudo apt-get install git-core
sudo rpi-update
sudo shutdown -r now

How to get Quake III running
http://myraspberrypiexperience.blogspot.co.uk/p/quake3.html

 

Getting sound working (I don't think this fixes sound in Quake III but it works for mp3s, videos etc)

Sound is disabled by default because the ALSA sound driver is still "alpha" (not fully tested) on the R-Pi. To try out sound, from the command prompt 
 sudo apt-get install alsa-utils
 sudo modprobe snd_bcm2835 
 sudo aplay /usr/share/sounds/alsa/Front_Center.wav
By default output will be automatic (hdmi if hdmi supports audio, otherwise analogue). You can force it with: 
 sudo amixer cset numid=3 <n>
where n is 0=auto, 1=headphones, 2=hdmi.
If you are running Debian, try 
 cd /opt/vc/src/hello_pi/hello_audio
 make ./hello_audio.bin
to test analogue output. And 
 ./hello_audio.bin 1

Fixing screen resolution problems

Big black borders around small image on HD monitors

Out of the box, R-Pi graphics don't necessarily fill the 1080p (ie Full HD) screen. This is due to something called "Underscan", and it can be fixed easily.
Edit the configuration file, see the instructions at R-Pi_ConfigurationFile.
(use sudo nano /boot/config.txt nano is a command line text editor)

Add the following lines to the configuration file...
If your display has no overscan: 
disable_overscan=1
CTRL o flowed by enter to save then CTRL x to exit nano
or if your display has some overscan: 
overscan_left=-20

overscan_right=-20

overscan_top=-20

overscan_bottom=-20

CTRL o followed by enter to save then CTRL x to exit nano
 
Making the R-Pi graphics fill the screen is a matter of experimenting with the numbers you put in the config.txt file. Change the numbers – try jumps of 5 or 10 at a time. Bigger negative numbers reduce the black borders (so -40 means less black border than -20). The numbers do not all have to be the same; you can use this feature to centre the display on the screen.

Playing video

You can install omxplayer a GPU enabled command line video player
wget  http://seyrsnys.myzen.co.uk/rpi/omxplayer_0.0.1-arm.deb

sudo dpkg -i omxplayer_0.0.1-arm.deb

sudo apt-get -f install

To play a video cd /the dicectory your video is in
omxplayer -o hdmi yourvideofile.mp4
if no sound
try omxplayer yourvideofile.mp4

video controls
P Pause, Q quite.

Left, right and down arrows, back, forward restart


setting up wifi


I used a GSKY LINK Model:GS-27USB
When I type lsusb it is reported as
ID 0bda:8187 Realtek Semiconductor Corp. RTL8187 Wireless Adapter
It only works when plugged into a powered usb hub, for this I am using a LOGIK model:LP4HUB10
To get it working install wicd like this sudo apt-get install wicd
Then startx, go to internet in the menu and run wicd, it will scan for networks and when you see your network click on properties and put in your wifi password, type of encryption used and ssid if it is a hidden network.
There are lots of different wifi cards on the market so look on the raspberry pi Forum http://www.raspberrypi.org/phpBB3/ for help setting up other wifi cards.
I hope this helps people get the most out of their raspberry pi. I will post more hows to for the raspberry pi as I learn more, please comment and tell me what you are doing with your raspberry pis.
