Short MIIMETIQ definition

Reading time: 2 – 3 minutes

M2MCF and MIIMETIQ

Last months in M2M Cloud Factory we have been working on MIIMETIQ. Last weeks I’ve been thinking about how to define MIIMETIQ shortly and this is my definition, please tell if you can understand something. Of course, you have to know we’re focused in Internet of Things and M2M market.

  • MIIMETIQ is an IoT/M2M framework, so this is the first step to setup to develop your vertical solution.
  • Framework: With a well defined architecture a framework is a set of functions ready to create any application. Everything else is open and adaptable.
  • MIIMETIQ architecture is service oriented and it uses AMQP as a message broker to connect the services.
  • MIIMETIQ has several modules, we define a module as a set of services. Basicly MIIMETIQ have 5 modules:
    • Identity Manager: manage users, groups, roles and all kind of entities the project needs and its security.
    • Assets Manager: a data model manager, the integrator creates the business logics and data models here.
    • Distribution System: this is a set of agnostitc connectivity layers to different types of devices.
    • A E N M: several time series and other signals flow through the AMQP, this data are events and using rules those events could be converted in alarms and some alarms have to be notified to proper services, systems or people.
    • Control Panel UI: this is an administration dashboard, in form of a UI to setup and monitor the most common uses of MIIMETIQ.
  • Using those modules usually the integrators create their own user interface to satisfy customer requiremests. In M2MCF we create those UI using ADUX (Advanced Development User Experience).
  • After configuring MIIMETIQ the integrator has 2 customized APIs to connect their code with MIIMETIQ. One of them is an API REST and another one is AMQP.
  • Finally everything inside MIIMETIQ could be customized, because the flexibility is very important when you have an horizontal solution.

sslsnoop – hacking OpenSSH

Reading time: < 1 minute

Using sslsnoop you can dump SSH keys used in a session and decode ciphered traffic. Supported algorithms are: aes128-ctr, aes192-ctr, aes256-ctr, blowfish-cbc, cast128-cbc.

Basic sslsnoop information:

 $ sudo sslsnoop # try ssh, sshd and ssh-agent… for various things
 $ sudo sslsnoop-openssh live `pgrep ssh` # dumps SSH decrypted traffic in outputs/
 $ sudo sslsnoop-openssh offline –help # dumps SSH decrypted traffic in outputs/ from a pcap file
 $ sudo sslsnoop-openssl `pgrep ssh-agent` # dumps RSA and DSA keys

Take a look into the project in sslsnoop github page.

Routerboard CRS125-24G-1S-2HnD-IN (Mikrotik) Cloud Switch

Reading time: 1 – 2 minutes

I bought this product a few weeks ago and finally I can enjoy it at home. With this product you have a firewall, gateway, switch and wireless box with:

  • 25x Gigabit Ethernet ports
  • 1x Fiber channel
  • 3G, 4G or any optional USB modem
  • With RouterOS inside you can manage: gateway, firewall, VPN and ad-hoc switching and routing configurations
  • 1000mW high power 2.4GHz 11n wireless AP
CRS125-24G-1S-2HnD-IN

CRS125-24G-1S-2HnD-IN

The official product page is here where you can find brochure in PDF and other useful information.

If you are looking for a powerful product for your SOHO network this is the solution as I like to say ‘this is one of the best communications servers’. It will be very difficult to find some feature or functionality that you can not get from this product. The product is robust and stable with the flexibility of RouterOS.

Conferència: La revolució dels mini-PC: Raspberry PI, Arduino i més

Reading time: 1 – 2 minutes

Ahir al vespre vaig fer una conferència a la FIB (Facultat d’Informàtica de Barcelona) dins de la UPC (Universitat Politècnica de Catalunya). En aquesta xerra vaig estar explicant què és i en que es diferència Arduino i Raspberry PI. A més de presentar tot un conjunt de solucions alternatives i experiències en el tema.

En aquest enllaç podeu trobar les transparències de:  La revolució dels mini-PC: Raspberry PI, Arduino i més. i el video el teniu disponible al servidor de la FIB.

Ara també teniu disponible el video a youtube:

i podeu veure les transparències des d’aquest mateix post:
