This is a really good book for those looking to research some hacking. It's also good to fill in a couple weak spots that you may have in your knowledge.
It covers some command-line stuff for applications like netcat, but not to the point your head will swim. Then it advises you to practice and develop your skills further.
At under 200 pages, it's nowhere near as intimidating for newbies (or even people who shudder at the thought of getting another 700+ page computer book.)
