Hi Don I know this post is old but I have been fooling around with FSCrack and with JTR current version and I have to admitt JTR is the fastest cracker I loaded about 500 hashes and left me with only 65 hashes to crack that is way fast in a micro second I was very surprise my Gosh JTR is a MF cracker WOW  anyway been studying hard I went ahead and purchased PrepLogic's CEH special Audio Cd quiz and learn and I converted to mp3 but the tracks had not track name so I went ahead and listened to the TOC and named each track but other than that been studying and learning the tools for hacking in a VM also my rainbowtable is growing big and cracking large passwords as I have special permission to audit our company's passwords its  been great to be an admin to an extreme l8r Don.
