We have also been contacted by other individuals interested in submitting answers to this challenge but were concerned because they were unfamiliar with the commands used by Mike Poor. Rest assured that both Ed Skoudis and Mike not only know a hell of a lot more than I do, but they also have tripled checked every line of the challenge. The preformatted text in the challenge is the actual dump from Mike's testing.
It is correct and it is meant to be just that... a challenge.
In fact, a missing space (that can't even be seen) was cutoff in the transfer of the challenge into html format. They caught it and made sure that I changed it. They're that good!
You have plenty of time to do research before submitting your answers. Remember - Google is your friend. So take your time and have fun with it. Along they way, we'll all be educated.
Best of luck,
