For those of you who have no clue what is all of this about, Aircrack-ng is a command line tool that allows you to bruteforce WEP and WPA wi-fi password protections.

WEP being the easiest protection to break, and WPA the hardest. The difference?. WEP can be broken in… two days, give or take (probably less than that), while WPA could take months… without results!. Personally, everytime i needed to break a WEP protection, i had to boot a linux system. If you’re like me, and you’d rather staying in OSX, this is juuuuust for you.

I don’t wanna forget about this, so i’m writing this short guide, right here!

1. Install Macports.
2. Install aircrack-ng:
   sudo port install aircrack-ng
3. Install the latest Xcode, with the Command Line Tools.
4. Create the following symlink:
   sudo ln -s /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport /usr/sbin/airport
5. Figure out which channel you need to sniff:
   sudo airport -s
6. Open up a terminal and type:
   sudo airport en1 sniff [CHANNEL]
7. Open up a seecond terminal and type:
   aircrack-ng -1 -a 1 -b [TARGET_MAC_ADDRESS] [CAP_FILE]

Notes: the cap_file will be located in the /tmp/airportSniff*.cap.
Nice, right?

Update:

I’ve been having issues while trying to crack a WEP key. I had over 100k IV’s… without luck. So i’ve attepted to crack the key with the KoreK algorithm (coded in aircrack-ng). And guess what!! i got the key!!. If you ever have the same problem, try this:

I’ve tried several RSS Readers for Mac. Many of them are free… such as Google Reader, or Capuccino. But a couple weeks ago i sumbled upon Reeder. I dare to say… it’s the best RSS Reader you’ll be able to find, anywhere else.

Why is that?. Well, the UI is pretty awesome… take a look:

Reeder has several UI styles. Personally, i use the layout portraited above. You get your feed list on the left… the posts in the middle, and the actual post on the right.

Now here’s something interesting. If you click over a post, the app hides the Feed List, and automatically enhances the post itself. Reeder has also something super cool. It’s Gestures-Enabled, which means that you can just swipe to the left or right, and trigger several actions (of course, you can configure that).

Most important of all… you can connect Reeder to your Google Reader account, and that’s it, this guy is gonna keep everything in sync. You could run it across several OSX installations, and… everything will be in sync.

I know it ** might ** be a bit expensive, for a simple rss reader. But trust me, this ain’t no simple reader.. and i believe it’s totally worth it!.

This is a nice trick i’ve learnt not long ago. Nice, and useful. If you run OSX, and you’d like Terminal to display the current folder, in its title… to looks something like this:

All you need to do is to edit the .profile in your home directory, and type the following line:

Nice, right?

I’ve been dealing with an annoying glitch in OSX 10.8.2. For some reason, ‘show in finder’ breaks down… on its own.

The workaround is…

Let’s just hope a real fix shows up, sooner rather than later.

This is a nice thing… you just need to do the following:
