Friday Distro: Kali Linux

story imageIn the Hindu pantheon, Kali represents death and change, the dispelling of evil and the devouring of the unwanted. She is forbidden, and even death itself, but therefore also an element of salvation. In the Linux world, she is like opening a can of whoop-ass on your server.

Kali Linux (appropriately named, if I may say so) is a Linux distro focused on penetration and exploit testing, and therefore the element of change that will get you to shore up all those gaping configuration gaps in your systems: it's perhaps your salvation! But enough metaphors. Practically, Kali Linux installs on a DVD or pendrive, and contains dozens and dozens of specialized penetration testing tools to test your system. It's developed by the folks at Offensive Security, and grew out of the well-acclaimed Backtrack Linux, which had the same focus.

It's based on Debian rather than Ubuntu so you get a dated version of the Gnome 2 desktop, but who cares? It's not really a desktop, just a platform for launching tools. Over three hundred of them, from information gathering to vulnerability analysis, password attacks, wireless attacks, spoofing, stress testing, reverse engineering, hardware hacking, forensics, and more. As mentioned, you can run it from a DVD, pendrive, or even remote-boot from PXE or install to Amazon cloud. To make it as useful as possible they support ARM aggressively including ARMEL and ARMHF (and of course Raspberry Pi and cousins), plus as many different wifi devices as humanly possible.

They're innovating, too, producing opensource products like the ISO of Doom (hardware backdoor), custom images, the Evil Wireless Access Point, and more.

Fun stuff if you want to ensure your system is as safe as possible; scary stuff if you don't want to bother. Kali's Distrowatch page has more information including a link to their excellent documentation (the best place to start if you want to know what else Kali does), but ZDNet has a good review and LinuxBSDOS has another cursory review with some decent screenshots.

From your site:
Opened up the board, and in less than 24 hours, dozens of spammer robots autoregistered and started spewing their usual crap.
All the popular cms's have antispam features built in.
I use a combination of automatically looking up posters on http://www.stopforumspam.com/ (using a drupal module) and blocking IP addresses based on a simple honeytrap. This is very effective, even with anonymous posting there are maybe one or two spam posts a week.
There is similar code that just uses php.
