I can not get wifi working on my Banana Pro with Bananian 15.01. 15.01. should actually support the onboard wifi chip, but I couldn't also find a complete tutorial. I changed to hardware-layout to "Banana Pro" via bananian-config, I added "ap6210" to /etc/modules (which is mentioned here: https://www.bananian.org/hardware) and I configured /etc/network/interfaces (like here: http://www.canox.net/2015/01/banana-pro-wlan-einrichten/):

1. auto wlan0
   
2. allow-hotplug wlan0
   
3. iface wlan0 inet dhcp
   
4. wpa-ap-scan 1
   
5. wpa-scan-ssid 1
   
6. wpa-ssid "WLAN-NAME"
   
7. wpa-psk "WLAN-KEY"

Copy the Code

After a reboot, wlan0 is found, ifconfig shows wlan0 and the ap6210 driver is loaded, but the DHCP discovery fails (nothing received). When I run "iwlist wlan 0 scan", no networks are displayed, but an error message: "Wireless Event too big".

Has someone a idea how this can get solved or what I could try to get it running?

Thank you in advance.

To install X-window, lets first update our resource lists with

  apt-get update

Then, to install X-window

  apt-get install x-window-system

I started using the XFCE window manager and its one of the most lightweight WMs on Linux. It has the look of Gnome and the lightweight of IceWM and X.

To install XFCE 4,

  apt-get install xfce4 xfce4-themes

To install other window managers like IceWM, Fluxbox, GNOME)

  apt-get install icewm fluxbox gnome

I like gdm (Gnome Desktop Manager) as my graphical login program, so

  apt-get install gdm

However you can also try xdm (X Desktop Manager) or kdm (KDE Desktop Manager)

  apt-get install xdm kdm

Changing your screen resolution

  dpkg-reconfigure xserver-xfree86

Choose your resolution and restart your X with either

  /etc/init.d/gdm restart

or

  startx

Removing graphical login

You are finally tired of graphical logins. To turn off the graphical logins (default in Sarge), you have to remove X startup from all run levels.

  update-rc.d xdm remove

X won't start again when your computer boots up. You'll be greeted by the console.

Hello !

I'm using Aircrack-ng on my BPI running Raspian v3

Quick installation tutorial for beginners :

Get root :

1. sudo su -

Copy the Code

Download required packages :

1. apt-get update
   
2. apt-get install libnl1 libnl-dev libnl-3-dev libnl-genl-3-dev iw

Copy the Code

Download aircrack-ng sources (grab last version) :

1. wget http://download.aircrack-ng.org/aircrack-ng-1.2-beta3.tar.gz

Copy the Code

Uncompress :

1. tar xvzf aircrack-ng-1.2-beta3.tar.gz

Copy the Code

Compile & install :

1. cd aircrack-ng-1.2-beta3
   
2. make

Bananian: GUI mit LXDE

LXDE steht für “Lightweight X11 Desktop Enviroment”, wobei “LX” gleichzeitig auf Linux hindeutet. LXDE ist eine freie Desktop-Umgebung für Unix Systeme. Unter dem Raspberry Pi wird dieses Tool am meisten genutzt, um mit einem Desktopmodus zu arbeiten. Für den Banana Pi, speziell für Bananian Linux erfolgt die Installation gleichermaßen mit folgenden Befehlen.
Zunächst bringen wir unser System auf den neusten Stand.
apt-get update
apt-get upgrade
Anschließend wir die Installation von LXDE gestartet.
sudo apt-get install task-lxde-desktop -y
Damit die Einstellungen übernommen werden erfolgt ein Neustart des Systems.
sudo reboot

Bananian: GUI mit Xfce

Alternativ zu LXDE kann ein Desktop durch das Tool Xfce entstehen. Diese Tool stellt ebenfalls eine Desktop-Umgebung bereit und ist für Unix Systeme. Weitere Informationen zu Xfce findet man unter Wikipedia. Xfce ist im Vergleich zu LXDE etwas schneller und ressourcenschonender.
Vor der Installation bringen wir ebenfalls unser System auf den neusten Stand.
apt-get update
apt-get upgrade
Danach erfolgt die Installation von Xfce mit folgendem Befehl.
apt-get install xorg xfce4 xfce4-goodies hicolor-icon-theme gnome-icon-theme xfce4-power-manager
Damit die Einstellungen übernommen werden erfolgt ein Neustart des Systems.
sudo reboot
