That is true. Knoppix STD is a must have toolkit. I always carry it with me. You can find plenty of live cd security framework distribution. You would love going through man pages and help given with the tools, if you really have that 'hacker' spirit inside you. I would say, do not OVERWHELM yourself with too much of information (but that does not mean that you stop reading till your eyes bleed). Just implement what you read.Figure out that what you intend to do for your penetration test. And then carry out each implementation/pen test using tools available in the CD. Go through the tutorials of nmap (fyodor recently released a more 'fun-version' of it with --arp-spoof, --send_ip, see the latest release notes for more information) and how can you milk nmap abilities combining it with amap in knoppix STD. You would love the rode.

Umm..I would suggest to go through CLUSTERKNOPPIX as well. Read the tutorial written by NeUtron (http://www.antionline.com/showthread...clusterknoppix) and the findings by some fellows. You would love the ride.

happy reading..
my 2 cents..
