Hello GreenHackerz readers.
The tutorial is for Linux operating system.
The tutorial is all about hacking root password of RedHat / Fedora / or RedHat based Operating System.
When you lost your root password in a RedHat Linux Based systems you should first have access to the console, (the machine itself). For that you have to power on or reboot your machine as needed and wait until you get the following screen (or similar depending your system and configurations).
Note : Here I am using the Fedora operating system but the process is same for all RedHat based system.
Now press 'a' and you will get the following screen......
now, give one space and press key '1' or write 'single' and hit enter button.
you will get the shell prompt screen as shown below
now use the password changing command used in Linux i.e passwd and hit enter . It will directly ask you the new password for user 'root'.
now type reboot and hit enter. you have done .
It will reboot your computer and now login with your new password
thats all..
hope you enjoyed the tutorial.
