Breaking Redhat Linux Root Password

September 10, 2007 at 10:08 am (Operating Systems, Security, Tips n Tricks)

There is a trapdoor provided for the redhat console in linux in case we forget root password. This even allows you to break through the root. Here is the process

At the time booting starts, it pings an option for going for linux or not. switch to linux option and go for edit mode instead of enter. Press e for that. This will take you to grub options.

Out of three lines edit both of options available and add ” 1″(space one) to them in the same way(pressing e). Then press b. This will start booting on command mode. After some initial booting it will stop at one point. Type passwd there and wat u see? ? it prompts for a new password. This will b your next root password. Reset and boot again..
