Thanks guys I didn't even know that Pentoo or backbox existed, I guess there is some more testing and playing around I will need to do before I decide my favorite. Now that said if I am looking at getting my OSCP would you recommend using Kali? I haven't seen any updated course ware and it seems it is still using Backtrack. One can only assume they are going to update the course ware to use Kali?
I've heard that they will be updating the course but as for when, I have no idea. If you plan on taking PWB, and you're new to hacking, I would probably stick with Backtrack (despite what I said in my previous post). If
you've already got a handle on what tools to use to get things done, you can certainly use other distributions.
As I said, Backtrack is no longer supported so you may run into some walls when trying to fix things that don't work. Certain tools referenced in PWB no longer come preinstalled with Kali (eg: unicornscan, MinGW), although you can certainly install them yourself. In fact, I believe the course material uses Backtrack 4, and when I took it, 4 was no longer supported and I was using 5R3 so some things were already different then. As long as you do a bit of reading and research, you should be able to follow the course material without too many problems.
