[opensuse] lost root password
12.3 Hi How do we rest the root password? We've been trying 3 hours and all we've found is to put this: init = /bin/sh Somewhere but w don't know how to get to that screen. Thanks. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

You could use LVM and Encrypt the whole Hard Disk Drive. Do not forget you Key or Password. That way it always ask for password first before get into the user session. Regards, -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Doesn't stop the boot CD/DVD/flash drive mechanism. A combination of a bios/uefi boot password and a hard drive ata drive password does work. The ata drive password keeps the drive from working except in the computer it is paired to. The bios/uefi boot password prevents the bios from activating the drive. I have seen that done in the real world, but encryption is much more common solution. Fyi: ata password capability is part of the ata spec so most drives should support it, but in many cases the manufacturer implements it poorly and the right software can remove it or determine what the password is Here's a post about hacking Seagate drives to determine the ata password: http://hackaday.com/2013/11/29/bypassing-seagate-ata-security-lock/ Here's the code: https://github.com/BlackLotus/seaget I gather you need a special cable to connect your PC's serial port (rs-232) to the drive's serial interface pins, then this code interrogates the drive and simply grabs a data buffer that has the password in plain text embedded.

It does need bios support, but it doesn't work as you describe from what I understand. The password is maintained by the bios. When the disk is powered on it initially refuses to accept read/write commands. The bios automatically sends the password and enables the drive. No user interaction required. Typically a user would also have a separate bios password setup that has to be entered. But that is a separate password, so the user only enters the ata password once when the bios and the drive are paired together. Makes it very easy to forget.

I knew about hdparm, but I have not noticed any entry in my BIOS for it. I will have another look. Even if it were unsecure, it is a deterrent on a laptop.

So you are trying method 3 from https://en.opensuse.org/SDB:Recover_root_password The "init=/bin/sh" arg is something you are adding to the kernel boot line. So based on which boot manager (grub, grub2, lilo) they each have their own way to go into an advanced boot method and add things to the kernel boot command. You should be able to figure that out via trial and error. === Personally I use method 1 from the wiki article. That is use a openSUSE boot CD.

(note: the following is from the sysVinit days, but should be the same since reboot is linked to systemctl reboot) 1. Boot the system and select the normal boot menu from the list. Once selected, in the “Boot Options” box type init=/bin/bash (if you are using GRUB Boot loader) linux init=/bin/bash (if you are using LILO Boot Loader) Do a mount command to check if the root file system “/” is mounted as Read-Write. In my system, it indeed mounted as Read-Write. opensuse:~ # mount Root file system mounted as Read-Write Otherwise, you may need to remount the “/” file system with read-write as follows: opensuse:~ # mount -o remount,rw / Now, simply type the passwd command and enter a new password: opensuse:~ # passwd Changing password for root New Password: Reenter New Password: Password changed Reboot the system and you are back in business. opensuse:~ # reboot -- David C.

Thanks.
(note: the following is from the sysVinit days, but should be the same since reboot is linked to systemctl reboot)
1. Boot the system and select the normal boot menu from the list. Once selected, in the “Boot Options” box type Hi OK. That's where we're lost. We don't have 'normal boot menu' on the list. We have: opensuse 12.3 advanced options for opensuse 12.3
The latter brings up another menu with 4 options, normal and advanced boot for each of two variants of the kernel that were installed, presumably as a result on an update).
init=/bin/bash (if you are using GRUB Boot loader)
linux init=/bin/bash (if you are using LILO Boot Loader)
Do a mount command to check if the root file system “/” is mounted as Read-Write. In my system, it indeed mounted as Read-Write.
opensuse:~ # mount
Root file system mounted as Read-Write
Otherwise, you may need to remount the “/” file system with read-write as follows:
opensuse:~ # mount -o remount,rw /
Now, simply type the passwd command and enter a new password:
opensuse:~ # passwd Changing password for root New Password: Reenter New Password: Password changed
Reboot the system and you are back in business.
opensuse:~ # reboot

All you need to do is type the init=/bin/bash into the boot options dialog (I believe you can just look at the bottom of the boot screen for the "boot options" hot-key and select it. Worst case, I believe you can just hit "e" for "edit" and drop to the traditional grub command line menu and edit the boot options there. Somebody with a current grub boot menu will have to chime in and give your the exact details. Honestly, from memory, all you need to do is press the "up-arrow" or "down-arrow" to stop the automatic count-down timer, and then you can look at the options at your leisure. I've used the exact procedure several times and it works like a charm. -- David C.
