Ok, thanks for your advice, I will probably dual boot so I can keep winXp, cause unfortunately the truth is that there are things that are easier/only possible in WinXp, but I prefer to work in Linux (esp. Ubuntu). I also was looking for some suggestions on which tools I should use. I know a couple but I was looking to make a list of all of your favorites that you use most regularly and for which purpose specifically you use them (Arp Cache Poisoning, Sniffing, Hash cracks, rainbow tables, etc.) , I will probably throw together a list of all the tools they use on the show.
Thanks :-)
