nUbuntu was just updated today to be based on Ubuntu 6.10 (Edgy Eft) that was released nearly a month ago. Many of you probably haven’t even heard of nUbuntu and don’t feel bad because I just learned about it a few weeks ago. It is another branch off of Ubuntu but it has several packages pre-installed that are geared towards security aware individuals. I guess that is the polite way to label the target audience because I would probably refer to them as hackers. 
You can find the list of pre-installed packages here and among them you’ll find wireless cracking software, sniffers, and scanners. Everything that makes a hacker’s, I mean security aware, mind go around. So if you’re itching to crack your neighbor’s wireless WEP key this is the tool you should use for the job.

In case anyone is curious, it’s a 263MB iso. Small enough for a quick looksee.
