LightBlue is a cross-platform Bluetooth API for Python which provides simple access to Bluetooth operations. It is available for Mac OS X, GNU/Linux and Nokia’s Python for Series 60 platform for mobile phones.
LightBlue provides simple access to:
* Device and service discovery (with and without end-user GUIs)
* Standard socket interface for RFCOMM and L2CAP sockets (currently L2CAP client sockets only, and not on PyS60)
* Sending and receiving files over OBEX
* Advertising of RFCOMM and OBEX services
* Local device information

coreboot (formerly known as LinuxBIOS) is a Free Software project aimed at replacing the proprietary BIOS (firmware) you can find in most of today’s computers. It performs just a little bit of hardware initialization and then executes a so-called payload.
With this separation of hardware initialization and later boot logic, coreboot is capable of scaling from specialized applications run directly from firmware, operating systems in Flash, and custom bootloaders to implementations of firmware standards like PCBIOS and EFI without having to carry features not necessary in the target application, reducing the amount of code and flash space required.

If you want to know the speed and type of your computer RAM module, it’s a method who helps you.
So lets begin, we need to use biosdecode command, and this is the correct option:
dmidecode --type 17

Aletheia (ἀλήθεια) is the Greek word for “truth”, and like the English word implies sincerity as well as factuality or reality. The literal meaning of the word ἀ–λήθεια is, “the state of not being hidden; the state of being evident”.

trapper is a sniffer & ARP poisoning tool made in perl. The current version supports sniffing protocols like HTTP, FTP, telnet POP3, IMAP, SMTP, MSN, IRC, SMB, SIP, TeamSpeak and VCN. Also this tool include the attack known as APR ( ARP Poison Routing ). More protocols and types of attacks will be added in the future. The development of Trapper was inspired in the excellent tool Cain, but we wanted a tool that also worked under Linux/Unix.
Features:
1. Supported protocols: HTTP, SMPT, IMAP, SMB, SIP, POP3, FTP, Telnet, IRC
2. HTTP Cookie Sniffing
3. IRC Chat Sniffing
4. SMPT sniffing (attachments supported)
5. MSN Chat Sniffing
6. ARP poison tool
7. Different types of ARP attack
8. Fake MAC tool
9. Firefox cookie injector
10. Passwords are saved automatically
11. Lenght of the packet option
12. Automatic Network Detection
13. Trapper.conf: You can add your own parameters to sniff HTTP values (yes like Cain); also choose if you wanna save or not the sniffed data and put your own ports on supported protocols

JWChat is a full featured, web-based Jabber™ client. Written using AJAX technology it relies on JavaScript and HTML at the client-side only. It supports basic
jabber instant messaging, roster management and groupchats based on the
MUC protocol.
JWChat is an advanced instant messenger (IM) just like AIM, MSN
Messenger, Yahoo! Messenger or ICQ. This means you can manage your
contacts, communicate with other users in 1:1 chat sessions or join a groupchat room for
collaborative communication. Unlike other IMs you can use this with your
web browser without having to install any additional software at
all.

If you want to see all rules of you firewall with PF using terminal you can do it with:
pfctl -s rules
We need to do it because the web manager of pfSense only shows the rules that you add by yourself, but there’s more roles created by default.

Some times there’s too many attacks who come from other countries, specially China, USA or Russia and we don’t need that these countries access to our network(or fuck our Internet BW), so then we need block it (yes I know, the best rule for our firewall is block all by default and permit the services and networks, but we’re going to think that we need to permit all and block only some countries).
So, for make it, we need to know the IP address networks of each country who we want to block (or accept in the ideal scenario), and we can use these sites:
http://blogama.org/country_query.php?country=ISO 3166
http://www.ipdeny.com/ipblocks/data/countries
The codes (ISO 3166) of the country are available in http://www.blogama.org/country.txt

If you want to know how’s the signal with your bluetooth device maybe you want to make a ping to it, like common ping used in IP networks.
So, for make it in bluetooth networks we have to use l2ping, for example:
# l2ping 00:11:C0:19:C9:C1
Ping: 00:11:C0:19:C9:C1 from 00:1A:6B:DC:F1:A1 (data size 44) ...
44 bytes from 00:11:C0:19:C9:C1 id 0 time 14.61ms
44 bytes from 00:11:C0:19:C9:C1 id 1 time 48.58ms

Motion is a program that monitors the video signal from one or more cameras and is able to detect if a significant part of the picture has changed. Or in other words, it can detect motion.
The program is written in C and is made for the Linux operating system.
Motion is a command line based tool. It has absolutely no graphical user interface. Everything is setup either via the command line or via a set of configuration files (simple ASCII files that can be edited by any ASCII editor).
The output from motion can be:
* jpg files
* ppm format files
* mpeg video sequences

I was searching something about integration of Arduino with Asterisk PBX and I found this interesting article:
Using Asterisk to Control your Arduino
This article is how to control Arduino over Ethernet using Asterisk PBX, making a call and controlling over it comm channel.
So then, you can make a IVR and control your Arduino calling it wherever you are.

n2n is a layer-two peer-to-peer virtual private network (VPN) which allows users to exploit features typical of P2P applications at network instead of application level. This means that users can gain native IP visibility (e.g. two PCs belonging to the same n2n network can ping each other) and be reachable with the same network IP address regardless of the network where they currently belong. In a nutshell, as OpenVPN moved SSL from application (e.g. used to implement the https protocol) to network protocol, n2n moves P2P from application to network level.
The main n2n design features are:
* An n2n is an encrypted layer two private network based on a P2P protocol.
* Encryption is performed on edge nodes using open protocols with user-defined encryption keys: you control your security without delegating it to companies as it happens with Skype or Hamachi.
* Each n2n user can simultaneously belong to multiple networks (a.k.a. communities).
* Ability to cross NAT and firewalls in the reverse traffic direction (i.e. from outside to inside) so that n2n nodes are reachable even if running on a private network. Firewalls no longer are an obstacle to direct communications at IP level.
* n2n networks are not meant to be self-contained, but it is possible to route traffic across n2n and non-n2n networks.
