Thank you very much for your help mate it is really appreciated

CRACK(8) System Manager's Manual CRACK(8)
NAME
Crack, Reporter - programs to break password files
SYNOPSIS
Crack [options] [-fmt format] [file ...]
Crack-Reporter [-quiet] [-html]
DESCRIPTION
This manual page documents briefly the Crack, and Crack-Reporter commands. This manual page was written for the Debian GNU/Linux distribu-
tion because the original program does not have a manual page. Instead, there is some documentation available at /usr/share/doc/crack
which you are encouraged to read
Crack is not a program designed to break the password of every user in the file. Rather, it is designed to find weak passwords in the
file, by attacking those sorts of bad passwords which are most likely to be used, in the order in which they would most easily be found
(ie: are most likely to be used by a moronic user).
Crack is not designed to break user passwords; it is designed to break password files. This is a subtle but important distinction.
Crack-Reporter will show what passwords have been cracked, as well as view errors that have been detected in the source password files,
etc. Guesses are listed chronologically, so users who wish to see incremental changes in the output as Crack continues to run over a
course of days or weeks, are encouraged to wrap invocations of Crack-Reporter in a script with diff.
OPTIONS
A summary of options are included below. For Crack:
-makedict
Creates and compresses the dictionaries Crack will use
-makeonly
Compiles the binaries for Crack (not necessary for Debian GNU/Linux since they are already provided)
-debug Lets you see what the Crack script is doing.
-recover
Used when restarting an abnormally-terminated run; suppresses rebuild of the gecos-derived dictionaries.
-fgnd Runs the password cracker in the foreground, with stdin, stdout and stderr attached to the usual places.
-fmt format
Specifies the input file format.
-from N
Starts password cracking from rule number "N".
-keep Prevents deletion of the temporary file used to store the password cracker's input.
-mail E-Mail a warning message to anyone whose password is cracked. See the script nastygram.
-network
Runs the password cracker in network mode.
-nice N
Runs the password cracker at a reduced priority, so that other jobs can take priority over the CPU.
-kill filename
-remote
Internal options used to support networking.
For Crack-Reporter -html Produces output in a fairly basic HTML-readable format. -quiet Suppresses the reporting of errors in the
password file (corrupt entries, etc)
EXAMPLES
To run Crack
# Crack -nice 10 /etc/passwd
If a Crack session is killed accidentally, it can be restarted with moderate efficiency by doing:
mv run/Dhostname.N run/tempfilename
Crack -recover -fmt spf run/tempfilename
However if all you wish to do is start cracking passwords from some specific rule number, or to restart a run whilst skipping over a few
rulesets, try:
Crack [-recover] -from N filename ...
...where N is the number of the rule to start working from.
FILES
/usr/share/Crack Location of the Crack program and scripts. /var/lib/Crack/ Location for the temporary files used by Crack.
SEE ALSO
You will find more documentation about Crack in the text files available in /usr/share/doc/crack-common Documentation includes the pro-
gram's Manual (in HTML and Text files), the User's Frequently Asked Questions (FAQ), examples, articles and even some humour.
