A reader, June 14, 1998 [1 out of 5 stars] This book disgraces the trees used for it's paper. I've never read something that was such a blatant attempt to capitalize off of an esoteric topic. Under the guise of a "hacker manual", this book will teach you nothing; except that your money would have been better thrown in the street. Don't support egotistical crackfiends. "Rt66 vice president Mark Schmitz took the initiative to donate equipment, the use of a T1, and the expertise of Rt66's computer security gurus." -- Security gurus that do not understand the value of backups.
