well cracking the linux password is not a very difficult job when u login by root you can do that directly by
[-]#passwd <username>
he will ask u to type your new unix password ,enter the new unix password.
then he will ask u to retype password ,do the same
u can break any unix account password by this method
for "root" u don't need to write username of root while using "passwd" command,ucannot break password of root by any normal user.

now suppose u r administrator and u forgot ur password then on boot loader screen
press "E"
then edit first line of boot loader and type
........................................... 1 and press "b" to boot from single user mode
then it will throw u to shell prompt
sh....#
then use "passwd "command to change the password of root
sh....#passwd
now he will ask u to type ur new password,and retype it
after doing this use reboot command and start the system in runlevel 3 or five and type your
new root password.

A simple solution for this crack is to have a boot loader password! ;-)

well in case u forget ur new password
u can go to boot loader screen and again start ur computer
in run level 1 in single user mode,then it will bring u to shell prompt
frm there u can again run the "passwd" command and change or retype ur old password
but in case u have a boot loader with password u cannot break ur linux root password. as if u forget ur boot loader password it will not allow u to edit at ur linux screen and u cannot do the rest of the job.fr that u have to use "rescue".

greetings all
for your kind information


i have to laugh to this

linux is the most secure of all Os available.
and the hacking methode that is explained here is equal to saying
" IF I HAD A KEY TO THIS DOOR I COULD OPEN IT" ..blah

being a root user means that you are the master
and its no wonder a master can control his well trained dog -> Linux (penguin actually) .

anyway the new distros dont allow anyone to be the root user
it only have a substitute user or sudo command to do admin tasks

so dont panic
you are safe with the guard penguin

for any details or security help
contact em anytime ...and it is opensource
so free service
