(SNIFF.TXT, 090496)

     Some suggestions for using SNIFF.EXE, a Fravia hacker tool
from 1990, hereby given in the public domain as FREEWARE (you owe
me nothing for it, I vouch for nothing: your computer may well
explode in your face if you use my programs, you are warned).

     Sniff is a "dead" files sniffer, i.e. searches for int_calls
and for CMPSB and SCANSB code, both being relevant for cracking
protection. Sniff does not care if you let it on an executable
file or not... as a matter of fact it will be used on executable
and overloads, but you may use it at leisure wherever you suspect
a working protection to be hidden. 

     DOS redirection works, therefore:
1)             sniff [file_to_be_examined] |more
will give you screens of data,
2)             sniff [file_to_be_examined] > prn
will print the data, and
3)         sniff [file_to_be_examined] > [new_file]
will create a file that you can examine at leisure

     You'll notice that the sniffed file will have "blocks" of
working interrupts and blocks of "fake" interrupts, in reality
only occurrences of the byte "CD". This is particularly apparent
in bigger files, and especially at the beginning and at the end
of a file.

     FraVia's hacker tools may not be the purest code
implementations around, but they do help a lot all fellow
crackers in their daily duty. Feel free to comment and criticize
them, feel free to ameliorate them. In the public domain are
following utilities for crackers:
COMPA     quick file compare utility 
SPALMA    utility to locate hidden databases in a file
MASSA     utility to locate hidden databases inside similar files
CERCA     byte_locate utility
SNIFF     this utility

     All public domain utilities are rough "dirty" programs from
the years 1988-1990, compiled in Turboc version 1. You may get
the latest versions of the same utilities if you send me YOUR
utilities.
