Ncrack is a new brute force tool made by nmap, it’s actually a alpha version but the product is really interesting to verify your password policies compliance and security. It support ftp, telnet, ssh, rdp … protocols.
Easy to use in command line, I only tested it with rdp, unfortunately with no success even knowing the password to be found. I assume it’s just an alpha bug. In my point of view the multi protocol implementation makes it an interesting tool for audit automation.
I’m interested by MQTT for two reason, the first one is related to its services and QoS management, the second by its network efficiency because I’d like to use it over a 3G communication system with a small and low cost plan.
MQTT promise is to be network efficient but, i’d like to see it with my eyes, so I’ll try to give you some measures I’ve done to confirm it. My fear is that keep alive communication for subscriber costs could be high and request some software adaptations.

MQTT (MQ Telemetry Transport) is a Message Queuing system for machine to machine communications. It allows communication of mobile systems over high latency, low bandwidth and poor quality networks. It manage communications over TCP (not over Http) to optimize the size of messages and it manages different quality of services. Depending of it, messages can be dropped, received multiple times of you can have the insurance to receive the message one and only one time.
It makes this protocol really interesting for the communication between a raspberry PI and a server when this communication is event driven and the communication link looks like a Edge/3G channel.
Mosquitto is an open source implementation for MQTT.
Here are some tips on how I implemented it, for a demonstration purpose
Tonight, I start working on a third project I have in my hack list for the moment, this one is based on bluetooth and I order some arduino stuff to make it live. The arduino itself is a leonardo and the bluetooth is a hc-05 attached to a larger shield to be connected with arduino board directly.
This article details how to use HC-05 to transfer data between arduino & mobile device based on Bluetooth. It includes HC05 source code for pairing and communicating.

Tonight, the hack objective is to communicate with 433Mhz equipments using Raspberry PI. For this, I use a 433Mhz receiver from Itead Studio bought at hack spark for 4.5€ with an emitter. Cabling is simple : VDD on 5V (I tryed to use 3.3V supply voltage but as a consequence the reception range is limited to a couple of cm) , GND goes to GND and One of the data pin going to pin 13 (gpio21/27). This is following elements found on that site : ninjablocks

The first step is to install a fresh wheezy raspbian environment and get the basis element to work :
Some new hacking on Raspberry PI, the objective is to get a TC74A5 3.3VAT temperature sensor working with a RPI. This sensor is a digital sensor type 2 wires I2C operating at 3.3V with a precision of 2°C.

Here is a quick hack to interface a temperature sensor to a BeagleBone Black unit.
I choose to use a Microship TCN75AVOA component. This SMS component is not really easy to use for prototyping but feasible. This component have a unit cost < 1€ and operate at 5V or 3.3V (as for BeagleBone). A Dip8 version exists. The communication with the CPU is numerical based on a two wire connection type I2C. It measures from -40°C to +125°C on 8b + 4b decimal with +/- 1°C precision.

Tuesday hacking evening is tonight to get start with BeagleBone as my RPI is not available for the project I have in mind. So the objective today is to get a LED blinking on BBB board.
