Hack ROOT password of Linux

Hack ROOT password of Linux

Here is one more interesting topic to read, Can we crack root password any Linux system?

Yes, if you have physical/console access to Linux system!!! You just have to reboot your Linux system in single user mode. If you believe it or not, it hardly takes 2 min to crack. It would be helpful when you forget root! Once long back I re-installed entire Linux system for just to reset my root password, don’t be sad for losing it – Everyone does.

ANYBODY CAN DO (ABCD) Steps:

STEP 1: Start/Restart your Linux system.

STEP 2: Press any key to interrupt GRub from booting default operating system, when you press any key GRub will list all operating systems installed in your system.

STEP 3: Select your operating system press “e” for edit options (In this case - No multiple Operating system installed, just CentOS).

STEP 4: Select kernel options and press “e” for edit, go till end of the line add option as “1” specifying single user mode. (Kernel: Path to kernel files and with options, i.e under “boot” partition /boot/vmlinuz-2.6.18-194.el5PAE read-only mode and defining root partition and run level)

STEP 5: Press “b” to continue booting with current kernel options, Linux system will be entering single user mode. 

STEP 6: Now! You just logged into your Linux system as root user (single user mode) but without prompting for password, so let’s go ahead and reset the password by using command “passwd”, which will prompt for new password.
