  • How To reset Backtrack4 root password without login?

Hi Geeks,
I forgot my password and have no privileged users.Is there anyway to get the default password back?
I followed This tutorial http://bit.ly/ec3jfn But still not working!
Any help?
you have Backtrack installed on a Pc or on a VM ?
you have a grub password ? if so it wont work.

Anyway it works fine on Bt4 but i think offensive security disabled the bug on bt4 r2 ( not sure).

no
What should i do?
If you have a LiveCD, just stick it in, boot into the live distro, and mount your hard disk. Let's say you mounted your disk (/dev/sda1 for example) onto /mnt/mydisk. Then you can simply chroot and run the passwd utility to change the root password.

First: use su to become root.
Then: chroot /mnt/mydisk so that the root of your filesystem becomes /mnt/mydisk
Then: passwd to change your password.

Also, you can edit the /etc/shadow file manually if you don't want to chroot and run passwd.
Have fun, and let us know if you need help!

lol don't you have an live cd ISO of BT4 ? if not, just download it from their wesbite.
I downloaded BT4r2.ISO last month but i gave the CD To one of my friends.I'm not going to redownload it because it's a 2gb file .

Easy! Grab Damn Small Linux (it's 50MB, that's damn small). Burn the ISO to a CD or make a bootable flash disk, and use it to execute the above plan.

With GNU/Linux there's about a million ways to do something, so don't worry too much about being locked out of your system. I've trashed enough GNU/Linux systems and there has always been a way to fix it. As a precaution, I like to keep System Rescue CD handy for such emergencies.
During boot hold shift until you see the grub menu, the edit the kernel line pressing e and add at the end of the kernel line the word. "single" and boot it, you should get to a basic root shell. Try it out.
