RTAI – the RealTime Application Interface for Linux – which lets you write applications with strict timing constraints for your favourite operating system. Like Linux itself this software is a community effort. If you are interested in what it does just join our mailing list and help our team!
RTAI supports several architectures:
* x86 (with and without FPU and TSC)
* x86_64
* PowerPC
* ARM (StrongARM; ARM7: clps711x-family, Cirrus Logic EP7xxx, CS89712, PXA25x)
* m68k (supporting both MMU and NOMMU cpus)
The RTAI distribution includes RTAI-Lab, a tool chain to convert block diagrams into RTAI executables and to monitor their operation on various targets.

FreeRTOS is a portable, open source, royalty free, mini Real Time Kernel – a free to download and free to deploy RTOS that can be used in commercial applications without any requirement to expose your proprietary source code.
FreeRTOS Features:
* Free RTOS kernel – preemptive, cooperative and hybrid configuration options.
* The SafeRTOS derivative product provides a high level of confidence in the code integrity.
* Official support for 23 architectures (counting ARM7 and ARM Cortex M3 as one architecture each).
* FreeRTOS-MPU supports the Cortex M3 Memory Protection Unit (MPU).
* Designed to be small, simple and easy to use. Typically a kernel binary image will be in the region of 4K to 9K bytes.
* Very portable code structure predominantly written in C.
* Supports both tasks and co-routines.
* Powerful execution trace functionality.
* Stack overflow detection options.
* No software restriction on the number of tasks that can be created.
* No software restriction on the number of priorities that can be used.
* No restrictions imposed on priority assignment – more than one task can be assigned the same priority.
* Queues, binary semaphores, counting semaphores, recursive semaphores and mutexes for communication and synchronisation between tasks, or between tasks and interrupts.
* Mutexes with priority inheritance.
* Free development tools (Cortex-M3, ARM7, MSP430, H8/S, AMD, AVR, x86 and 8051 ports).
* Free embedded software source code.
* Royalty free.
* Cross development from a standard Windows host.
* Pre-configured demo applications for selected single board computers allowing ‘out of the box’ operation and fast learning curve.

Testing a Cisco Aironet 1250 series I needed to enable WPA, so these are the steps I did it via web GUI:
In SECURITY > Encryption Manager
Set Cipher: TKIP
Set Encryption Keys clean
in SECURITY > SSID Manager > Client Authenticated Key Management
Set Key Management: Mandatory
Enable WPA with you preferred version, and create your WPA Pre-shared Key as you want
And that’s all..

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.

How to see the process tree with ps command?
There’s some options:
ps -ejH
ps axjf
Or also we can use other command:
pstree
More info:
http://www.linfo.org/pstree.html
http://linux.die.net/man/1/ps
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.
More info
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
