Reset Linux r00t(root) Password - BackTrack 4 r2 [d1t1]

*All we need is a LiveCD Linux system, i am using BackTrack 4 r2 LiveDVD
Download BackTrack 4 r2 ISO file here: http://www.backtrack-linux.org/downlo...
I am using Virtual Machine with VMware

First you can see that my installed Backtrack 4 r2 system requires a password!!!

Second i connect the ISO file - or insert the DVD and than Boot IT UP in bios
Starting the LIVE DVD from ISO with VMware - we need to select the boot device
in vmware we can open the menu with ESC

Third reset the Password - just watch how i do it

In some linux systems the username/password database is located at "/etc/passwd"
If you have any other linux system just search on google where the username/password file is located
In Mac OS X is located "/etc/passwd"
BUT in Backtrack 4 r2 is located at "/etc/shadow"
To make the change we need to mount first the partition where our linux system is located.

All you have to do is remove the second words between ":" of the user, in this case is root and
i change this:

root:blahblahblah:15098:0:99999:7:::

to this:

root::15098:0:99999:7:::

"blahblahblah" is the encrypted password
i am using nano, to save press CTRL+X and than Y and ENTER -- then unmount the Partition!
then reboot and see it yourself, root is without password! [d1t1]

Sorry i Made a mistake for MAC OS X
You can reset password in MAC OS X by reading this page:
