Intro

I am a Digital Forensics student studying at university in the UK. I also do some Cyber Security modules.
I am currently in my 2nd year.
I have mainly started this to post interesting things I have learned and problems I have encountered.
However, I will use it to do write ups about useful things I want to remember such as commands and tools I have used so I don't forget them! (To be honest, I don't expect anyone to read this!)

Change Root Password Linux

I installed Deft earlier today, and when i first came to login, i did not want to login as the user i created during setup, i wanted to be Root.
So i selected "Other" from the menu, typed in "root" and typed in the root password for Deft which is "deft".

Error, Password Not Correct.

Oh...


Some Googling around ensued and confirmed that the root password should be "deft".

Okay, well something must have f'ed up somewhere!
So i thought, ahh, ill just change the password!

I have never done this before in Linux, only ever on Windows which takes about 2 seconds. (God bless Hirens Boot Disc).

So i had a quick Google and found a solution. Again, this post is mainly for me to remember the commands.

This solution works with Grub 2.
From here: http://fedoraproject.org/wiki/How_to_reset_a_root_password

At the Grub boot menu, press "e" on the one you want to change.
Side note here, my Grub menu didnt automatically appear, but i found out that if you hold down SHIFT when booting, it forces the boot menu to appear.

Find the line that starts with "linux" or "linux16".
At the end of the line, type "rw init=/bin/bash"
Press CTRL+X to reboot into that editing command.

You will come to a terminal screen.
Type "passwd"
It will prompt for a password, and again.

Reboot. All Done :)
