TAILIEUCHUNG - Unix Use and Security From The Ground Up_ The Prophet

A Unix system can easily be identified by its prompts. When you first connect to a Unix system, you should receive the login prompt, which is usually "Login:" (Note, that the first character may or may not be capitalized.) On some systems, this prompt may be ";Login:" or "User:" (Again, the first letter may or may not be capitalized.) This may be preceded by a short message, | Unix Use and Security From The Ground Up by The Prophet December 5 1986. INTRODUCTION The Unix operating system is one of the most heavily used mainframe operating systems today. It runs on many different computers Dec VAX s AT T s 3bx series PDP-11 s and just about any other you can think of- including PC s and there are many different but pretty much similar versions of it. These Unix clones go by many different names- here are the most common Xenix Ultrix Ros IX 370 for the IBM 370 PCIX for the IBM PC and Berkely BSD Unix. This file will concentrate on AT T System V Unix probably the most heavily used version. The next most heavily used is Berkely Unix. This file will cover just about everything all but THE most advanced hacker will need to know about the Unix system from the most rodent information to advanced hacking techniques. This is the second version of this file and as I discover any errors or new tricks I will update it. This file is to the best of my knowledge totally accurate however and the techniques in it will work just as described herein. Note that these techniques will work on System V Unix. Not necessarily all but most should work on most other versions of Unix as well. Later if this file is received well and there is demand for another I will release a file on yet more advanced techniques. If you wish to contact me I can be reached several ways.
