Title: John The Ripper setup
Subject: hack your passwds

John the ripper is a good cracking program that came after "CRACK".
This is a summery of useful examples from the docs.

First, try a wordlist (like the diconary for you ispell checker):
        john -w:words.lst passwd.1
        john --wordfile=words.lst passwd.1

To continue cracking in the background. 
	nice -n 20 john -w:words.lst -rules passwd.1 &

To only crack accounts with a good shell         
	john -w:words.lst -rules -shells:sh,csh,tcsh,bash passwd.1

To crack all the files you need cracked simultaneously:
        john -w:words.lst -rules passwd.*
To try salts with two or more passwords faster, and then
 try the rest.  Total cracking time about the same, but you
 get some passwords cracked earlier.
        john -w:words.lst -rules -salts:2 passwd.*
        john -w:words.lst -rules -salts:-2 passwd.*

To try 26 different characters only, passwords from
'a' to 'zzzzzzzz':
        john -i:alpha passwd.1

The most powerful cracking mode in John is called "incremental" defined
in ~/john.ini's [Incremental:All] section. 
  use the full 95 character set,
  try all possible password lengths, 
  from 0 to 8.
         john -i passwd.1

 The default wordlist rules include ':' (which means "try words
as they are in the list") as the first line.
