Make sure the Banana Pi is switched off to prevent any possible damage. Software Setup Double check the wiring and boot the device.

As you may have noticed the BPi has a green LED, which starts blinking as soon as the Pi is powered on: i.e. as soon as something happens with the SD card. It is possible to program the behavior of the LED such as switching it off. To list the available options open a terminal and enter cat /sys/class/leds/green :ph24 :led1 /trigger . The default value is heartbeat . If you want to permanently switch it off the trigger needs to be set to none . user@lemaker ~ $ cat /sys/class/leds/green:ph24:led1/trigger none battery-charging-or-full battery-charging battery-full battery-charging-blink-full-solid ac-online usb-online mmc0 timer [heartbeat] backlight gpio cpu0 cpu1 default-on user@lemaker ~ $ sudo su root@lemaker:~# echo none > /sys/class/leds/green:ph24:led1/trigger The LED may be manually turned on and off using the brightness file.

Given that I finally received my Banana Pi, it is time for a little review of the Chinese Raspberry Pi "competitor". Before I tell you about my first experiences with the board, let's have a quick look at its hardware specs and how they compare to the newly released Raspberry Model B +.   Hardware The first thing that sticks out is the Banana Pi's much faster dual-core, Cortex-A7-based Allwinner A20 system-on-chip running at 1GHz, which definitely beats the Raspberry's "well-known" 700MHz, ARM11-based Broadcom BCM2835 processor. The Banana Pi is also equipped with 1GB of RAM and built-in Ethernet that can handle up to 1Gbps, which is approximately ten-times as fast as the Raspberry Pi's. Raspberry Pi Model B+ The only area where the new Model B+ can really shine, next to the 4 x 2.0 USB ports, is the additional GPIO headers. There are now 40 compared to 26 on the Model B. The Banana Pi's GPIO layout is the same as the Raspber

Steps should be performed with root access: i.e. sudo su Add the following lines to /etc/apt/sources.list.d/i2p.list nano /etc/apt/sources.list.d/i2p.list      deb http://deb.i2p2.no/ stable main   deb-src http://deb.i2p2.no/ stable main  Download the key used to sign the repository and add it to apt apt-key add debian-repo.pub   Update repositories and install i2p apt-get update   apt-get install i2p i2p-keyring   Run i2p ( NEVER AS ROOT! ) i2prouter start  

Mate is forked from the unmaintained code base of GNOME 2 and has become quite popular. To install it on your debian wheezy, the following steps are required. sudo su   add-apt-repository  'deb http://repo.mate-desktop.org/debian wheezy main'    apt-get update   apt-get --yes --quiet --allow-unauthenticated install mate-archive-keyring   apt-get update   Install MATE core, the MATE desktop environment and the extras. sudo apt-get install mate-desktop-environment-extra  

This is a rather annoying "feature". Simply disable it by typing the following in a terminal. gsettings set org.gnome.desktop.interface enable-animations false

First thing you have to do is attach a jumper wire to GPIO 4. That's it for the hardware part. The Software The Code that does the job is called Pifm by icrobotics.co.uk . wget www.icrobotics.co.uk/wiki/images/c/c3/Pifm.tar.gz   tar -xvf Pifm.tar.gz   Start Broadcasting sudo ./pifm sound.wav 100.5   - sound.wav - the audio file which you would like to broadcast. only .wav will work. - 100.5 - the FM frequency. usually between 87.5 and 108.0 MHz.

Couldn't get my SD card reader to work.

It should be automatically mounted.

It is actually pretty easy to  send emails with python. The smtplib module provides the necessary "tools" to send mail to any Internet machine with an SMTP or ESMTP listener daemon.

No need to install anything. Just open a terminal and execute the following command to get the temperature of your RasPi. /opt/vc/bin/vcgencmd measure_temp Automate the process The below script will automatically reboot your Raspberry Pi should it reach a specified threshold (maxtemp). First of all make sure you can reboot/shutdown your raspi without linux asking you for a password.  user@user:~$ sudo visudo Add the following to the sudoers file.  user ALL=NOPASSWD: /sbin/shutdown The script Save as temp.sh. Maxtemp specifies the temperature cut-off point, at which the Raspi will reboot.  #!/bin/bash #title :temp.sh #description :Checks Temperature of Raspberry Pi and reboots at maxtemp. #author :Mike M | www.linuxx.eu #notes :Add "user ALL=NOPASSWD: /sbin/shutdown" to sudoers file temp=`/opt/vc/bin/vcgencmd measure_temp | cut -c 6-7` maxtemp=75 if [ $temp -ge $maxtemp ]; then xmessage "Alert!

This is a tutorial on how to securely host and run your own Tor hidden service. First thing that's required is your own web server and secondly you need to  configure the server in such a way as to prevent any possible information leaks (most importantly your location!). This tutorial makes use of whonix , which means any accidental leaks (DNS, IP etc.) are highly unlikely. For even better security consider using a dedicated machine for running your web server. So go ahead, download Whonix Workstation + Gateway . Download VirtualBox ,  import the .ova files and fire up your machines.  On the Whonix Gateway sudo nano /etc/tor/torrc #make sure to add the following 2 lines to file, save and exit HiddenServiceDir /var/lib/tor/hidden_service/ HiddenServicePort 80 10.152.152.11:80 Restart Tor sudo service tor@default reload A a hostname (e.g. 123xuadfuhqwer.onion) has been created! You can obtain it by displaying the contents of the  "hostname" file. sudo cat

Python 2.7.3 In order to geolocate an IP address with Python you will need a database to match an IP to a location.

Yes, Unetbootin is a great tool, but for some reason I can't get it to work in Debian. Fortunately you can achieve the same by using the command line and it is nearly as straightforward as using unetbootin. First, we want to get the exact name of our USB device. sudo fdisk -l The output should be similar to mine. Disk /dev/sdb : 2013 MB, 2013265920 bytes  Now that we now the location, we want to write our .iso or .img file to the USB. dd if='/home/user/Downloads/linuxmint-201403-mate-dvd-64bit.iso' of=/dev/sdb This will take some time, so be patient and do not interrupt the process.

The Problem For several reason I do not have access to LAN and thus have to rely on WIFI for my mining rigs. It is fine for most of the time, but the shit hits the fan, when the connection drops for one reason or another. The Solution #!/bin/bash wlan=`/sbin/ifconfig wlan1 | grep inet\ addr | wc -l` if [ $wlan -eq 0 ]; then service network-manager restart else echo WIFI IS UP fi Note: It's either wlan0 or wlan1. Check with sudo ifconfig . Save the script and make it executable. sudo chmod +x filename.sh Now there are several ways of making sure that our script is being executed every x minutes. The easiest way of accomplishing that I think is by using the command watch . sudo su watch -n 600 sh filename.sh What it does is execute our filename.sh script every 600 seconds. Or you implement a so called cron job   sudo crontab -e Add the following PATH=/usr/sbin:/usr/bin:/sbin:/bin */5 * * * * sh /home/username/filename.sh */5 * * * * means that

Crypt module I am using the crypt module here, which is a one-way hash function based upon a modified DES algorithm. You can easily adjust the script to crack secure hash algorithms (SHA1, SHA224, SHA256, SHA384, and SHA512 (defined in FIPS 180-2) as well as RSA’s MD5 algorithm ) by using the hashlib   module.
