How to unzip very large files

Some windows programs use a compression for larger files that is not compatible with the linux unzip command. Resulting in the following error:

need PK compat. v4.5 (can do v2.1)

There is a special program for handling these large files: p7zip

Run these commands to install and run:

$ curl -o p7zip_4.20_src.tar.bz2 http://internap.dl.sourceforge.net/sourceforge/p7zip/p7zip_4.20_src.tar.bz2

$ bunzip2 p7zip_4.20_src.tar.bz2

$ tar xvf p7zip_4.20_src.tar

$ cd p7zip_4.20_src

$ make

$ make install

$ 7za x largefilename.zip

This saved my ass… let me know how it works for you.

launchd: Better than sliced bread – Chris Hanson

Chris Hanson – launchd: Better than sliced bread
Simply put, launchd is what makes it easy to get tasks launched on-demand on Mac OS X 10.4 and later. It obviates lots of different archaic Unix infrastructure — init.d, cron, inetd — in favor of a single self-consistent and easy to use mechanism. Dave Zarzycki’s post Where to begin? describes the launchd design philosophy in some depth.

Processes launched at startup on Mac OS X are managed by launchd. There’s no careful balancing of init.d or SystemStarter scripts on modern releases of the operating system. Instead, launchd jobs have property list entries in the LaunchAgents and LaunchDaemons directories in the system and local domains. Some specify that launchd should keep them alive indefinitely, others simply provide conditions under which they should be launched.

For instance, the standard finger daemon indicates that it should be run whenever something connects to the socket corresponding to the finger service; it doesn’t run all the time, nor does it rely upon a separate “network service daemon” to launch. Similarly, the Bluetooth daemon is only run only when a particular Mach port is connected to; it doesn’t need to be running all the time, and a framework interacting with it can easily just connect to it and start using it, without worrying about the mechanics of launching it, ensuring only one instance is running, and so on.

Where launchd really shines is in the level of integration it lets developers offer between frameworks and daemons or agents when it comes to managing shared state.

How To Crack WEP

Here are a few much better links which use a variety of tools including Aircrack:

How To Crack WEP – Part 1: Setup & Network Recon
Introduction : How To Crack WEP – Part 1: Setup & Network Recon
Hundreds, perhaps thousands of articles have been written about the vulnerability of WEP (W ired E quivalent P rivacy), but how many people can actually break WEP encryption? Beginners to WEP cracking have often been frustrated by the many wireless cards available and their distribution-specific commands. And things are further complicated when the beginner is not familiar with Linux.

In this three part series, we will give you a step by step approach to breaking a WEP key. The approach taken will be to standardize as many variables as possible so that you can concentrate on the mechanics of WEP cracking without being hindered by hardware and software bugs. The entire attack is done with publicly available software and doesn’t require special hardware – just a few laptops and wireless cards.

Professor Messer – Using Nmap to Find Rogue Devices

Professor Messer – Using Nmap to Find Rogue Devices
Nmap is one of the best port scanners in the world, but did you know that Nmap can tell you the exact application name and version number hiding behind each port? More importantly, Nmap can tell you about the applications that you DONT want to see Nmaps version detection capabilities can provide you with an easy method of identifying rogue devices.

What is Version Detection?

Nmaps version detection feature identifies applications by performing intelligent queries of open ports. Even if the application is using a non-standard port, Nmap will correctly determine the application type.

Nmap uses a huge database of applications contained in the service file nmap-service-probes. This is constantly growing, so you may find additional services identified as time goes on. If youve found a new application, you will be given instructions on how to contribute your discovery to the next Nmap version
