==Installing Raspbian==
 +
 +
#Download Raspbian image from [http://www.raspberrypi.org/downloads/ here].<br />
 +
#Format SD card using FAT32.<br />
 +
#:<pre>sudo mkdosfs -F 32 -v /dev/mmcblk0</pre>

==Raspbian default username & password==
 +
By default the username and password are:<br />
 +
Username: pi<br />
 +
Passowrd:raspberry
 +
 +
==WiFi setup==
 +
===WPA2===
 +
1. Scan wifi networks available:
 +
<nowiki>sudo iwlist wlan0 scan</nowiki>
 +
2. Write down the ESSID (wifi network name) and IE (authentication used)<br />3. Edit /etc/wpa_supplicant/wpa_supplicant.conf, add the following at the bottom of the file.
 +
<br /><syntaxhighlight lang="text">
 +
country=ES
 +
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
 +
update_config=1
 +
network={
 +
    ssid="MyWiFiNetwork"
 +
    psk="MyWiFiPassword"
 +
    key_mgmt=WPA-PSK
 +
}
 +
</syntaxhighlight>
 +
  network={
 +
      ssid="The_ESSID_from_earlier"
 +
      psk="Your_wifi_password"
 +
  }
 +
4. If after a few seconds the Raspberry WiFi isn't connected:
 +
<nowiki>
 +
      sudo ifdown wlan0
 +
      sudo ifup wlan0 </nowiki>
 +
 +
===WPA2 + hidden SSID===
 +

 +
Edit /etc/network/interfaces
 +
<nowiki>
 +
      # /etc/network/interfaces
 +
      allow-hotplug wlan0
 +
      auto wlan0
 +
      iface wlan0 inet dhcp
 +
      wpa-ap-scan 1
 +
      wpa-scan-ssid 1
 +
      wpa-ssid "SSID"
 +
      wpa-proto RSN
 +
      wpa-pairwise CCMP
 +
      wpa-key-mgmt WPA-PSK
 +
      wpa-psk "PASS"</nowiki>
 +
 +
==wpa_suplicant==
 +
Not Working:
 +

 +
<nowiki>auto lo
 +
     
 +
      iface lo inet loopback
 +
      iface eth0 inet dhcp
 +
     
 +
      allow-hotplug wlan0
 +
      auto wlan0
 +
     
 +
      iface wlan0 inet dhcp
 +
              pre-up wpa_supplicant -Dwext -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf -B</nowiki>
 +
Edit /etc/wpa_supplicant/wpa_suplicant.conf
 +
<nowiki>
 +
      ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
 +
      update_config=1
 +
     
 +
      network={
 +
          ssid=NETWORK_NAME # it can be any encryption type, just make sure to add the "scan_ssid=1" line after your settings.
 +
          psk=password_without_double_quotes
 +
          scan_ssid=1
 +
          mode=0
 +
          protp=WPA2
 +
          key_mgmt=WPA-PSK

 +
          id_str="raspII"
 +
          priority=1
 +
     
 +
      } </nowiki>
 +
Another example:
 +
<nowiki>ctrl_interface=/var/run/wpa_supplicant
 +
      update_config=1
 +
      ap_scan=2
 +
      eapol_version=1
 +
      network={
 +
              ssid="YOUR-SSID-GOES-HERE"
 +
              scan_ssid=1
 +
              mode=0
 +
              proto=WPA2
 +
              pairwise=TKIP
 +
              group=TKIP
 +
              key_mgmt=WPA-PSK
 +
              psk="YOUR-PASSWORD-GOES-HERE"
 +
      }</nowiki>
 +
 +
=== WiFi BBVA ===
 +
<syntaxhighlight lang="text">
 +
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
 +
update_config=1
 +
network={
 +
ssid="BBVA"
 +
key_mgmt=WPA-EAP
 +
eap=TTLS
 +
identity="XE505824"
 +
password="********"
 +
phase2="auth=MSCHAPV2"
 +
}
 +
</syntaxhighlight>
 +
 +
==Domain name setup==
 +
To change the domain server:<br />
 +
Edit /etc/hosts<br />
 +
Edit /etc/hostname<br />
 +
Commit changes by runing:<br />
 +
sudo /etc/init.d/hostname.sh<br />
 +
 +
==Use network time server (NTP)==
 +
<syntaxhighlight lang="bash">
 +
sudo systemctl start systemd-timesyncd
 +
sudo systemctl enable systemd-timesyncd
 +
</syntaxhighlight>
 +
 +
==ssh rsa key setup==
 +
1. If you don't have an rsa key generate one by runing:
 +
<nowiki>ssh-keygen -t rsa -C user@domain</nowiki>
 +
2. Upload the .pub rsa key to the raspberry<br />
 +
3. Add the .pub key to ~/.ssh/authorized_keys
 +
<nowiki>cat rsa_key.pub >> ~/.ssh/authorized_keys</nowiki>
 +
 +
==Git server==
 +
1. Install Git:
 +
<nowiki>sudo apt-get install wget git-core</nowiki>
 +
2. Format an USB with FAT32, and connect it to the Raspberry (First turn off the raspberry)<br />
 +
3. Set up a mount point for the USB drive. <br />
 +
3.1 Create directory<br />
 +
3.2 Edit /etc/fstab, add line:
 +
<nowiki>/dev/sda1 /home/pi/usbdrv vfat uid=pi,gid=pi,umask=0022,sync,auto,nosuid,rw,nouser 0 0</nowiki>
 +
note: /dev/sda1 should correspond to usb drive you want to map, pi = user that will own the drieve. umask sets the permissions (substract from 7 the chmod octal value (to set rwx use 0...)<br />
 +
4. reboot Raspberry and check if the usb mounts correctly with lsblk<br />
 +
5. For each repository:<br />
 +
5.1 create a folder and cd into it.<br />
 +
5.2 git init --bare<br />
 +
5.3 add origin to your local git repository. Example:
 +
<nowiki>git remote add pi pi@10.0.1.64:/home/pi/usbdrv/justdiedbot.git</nowiki>
 +
5.4 push your repository into raspberry. Example:
 +
<nowiki>git push pi master</nowiki>
 +
 +
==Disable sleep mode==
 +
The file /etc/kbd/config contains settings for non-x screen blanking.
 +
 +
change the following:
 +
BLANK_TIME=0
 +
BLANK_DPMS=off
 +
POWERDOWN_TIME=0
 +
 +
===Disable Realtek 8192cu WiFi Sleep Mode===
 +
Edit: /sys/module/8192cu/parameters/rtw_power_mgnt
 +
cat /sys/module/8192cu/parameters/rtw_power_mgnt
 +
If the file doesn't exist your WiFi adapter uses a diferent chip.<br />
 +
If it's set to:<br />
 +
1: Power safe is enabled<br />
 +
2: Power safe is disabled<br />
 +
 +
Create a new file:
 +
sudo nano /etc/modprobe.d/8192cu.conf
 +
With the following content:
 +
<nowiki>
 +
      # Disable power management
 +
      options 8192cu rtw_power_mgnt=0</nowiki>
 +
Then reboot. And it's done.
 +
 +
==Print Server==
 +
===Install CUPS===
 +
sudo apt-get update
 +
sudo apt-get install cups
 +
Add your raspberry user to lpadmin group.
 +
sudo usermod -a -G lpadmin <user_name>
 +
Log out and log in again for the changes to take effect.<br />
 +
If you are in a trusted network execute:
 +
cupsctl --remote-any
 +
sudo /etc/init.d/cups restart
 +
Connect to the cups management via web browser:<br />
 +
http://raspberry_ip:631<br />
 +
Configure your printer.<br />
 +
To add scanner compatibility you must follow more steps explained in:<br />
 +
http://www.raspberry-pi-geek.com/Archive/2013/01/Converting-the-Raspberry-Pi-to-a-wireless-print-server
 +
 +
==Keyboard Layout==
 +
sudo nano /etc/default/keyboard
 +
XKBLAYOUT="es"
 +
or
 +
dpkg-reconfigure keyboard-configuration
 +
 +
==Raspberry PI HDMI-VGA Compatibility==
 +
[[Raspberry Pi: HDMI-VGA Converter]]<br />
 +
When Raspberry Pi is using a HDMI-VGA adapter is necessary to add an extra configuration in config.txt file (It must be located in boot partition directory but If it does not exist you need to create it). Add next lines at the begining of the file.
 +
<nowiki>#HDMI-VGA Configuration
 +
      hdmi_force_hotplug=1
 +
      hdmi_group=2
 +
      hdmi_mode=16
 +
      hdmi_drive=2</nowiki>   
 +
 +
This setting will force a screen size of '''1024x768 60 Hz'''. Although the screen does not support the new setting will work.
 +
<br />
 +
<br />
 +
Note: This setting works for '''Kali''' and '''Raspbian''' OS.
 +
 +
==Install Python Pillow==
 +
 +
wget http://www.zlib.net/zlib-1.2.11.tar.gz
 +
wget http://www.ijg.org/files/jpegsrc.v8c.tar.gz
 +
extract both: tar -xzvf ...
 +
./configure
 +
./make
 +
./make install
 +
both...
 +
pip install Pillow

      You have to re-install PIL and also install the needed libraries as well as link them manually. This answer is based on this blog post for a regular ubuntu PIL installation and this askubuntu question, where it is explained how to compile the jpeg encoding:
 +
     
 +
      ### uninstall PIL
 +
      sudo pip uninstall pil
 +
     
 +
      ### download and compile the JPEG library
 +
      wget http://www.ijg.org/files/jpegsrc.v8c.tar.gz   
 +
      tar xvfz jpegsrc.v8c.tar.gz
 +
      cd jpeg-8c
 +
      ./configure --enable-shared --prefix=$CONFIGURE_PREFIX
 +
      make
 +
      sudo make install
 +
     
 +
      ### link the libraries correctly - RASPBERRY PI ONLY
 +
      sudo ln -s /usr/lib/arm-linux-gnueabi/libjpeg.so /usr/lib
 +
      sudo ln -s /usr/lib/arm-linux-gnueabi/libfreetype.so /usr/lib
 +
      sudo ln -s /usr/lib/arm-linux-gnueabi/libz.so /usr/lib
 +
     
 +
      ### install rest of the libraries, as well as freetrype and zlib
 +
      sudo apt-get install libjpeg-dev libfreetype6 libfreetype6-dev zlib1g-dev
 +
     
 +
      ### re-install PIL
 +
      sudo pip install pil</nowiki>

 +
dtoverlay=w1-gpio # One wire for sensors sudo systemctl start systemd-timesyncd
