In this assignment we learned how to enter single user mode and change root's password inside it.

Notes

First I rebooted the system and pressed space (might be different system to system, Kali seems to display the right screen for a few seconds at startup as well) to get the following options:

Then I selected the first option, “Kali GNU/Linux” (letter e), then tweaked the settings at the end of the linux line (splash) and addded the following:

• single init=bin/bash

After that I pressed CTRL+X, which after a time entered me into a root prompt where I executed the following (screenshot shows the commands in use):

• mount -rw -o remount /
• • Mount the slash (/) directory
• passwd
• • Set roots password

With that finish I executed the following commands:

• sync
• umount /

And power cycled my Kali box, where I could now log in as root if I wanted.
