discussion about forgotten root password

Hi all,

any body know that, if he forgot the root password, he can passes an argument 1 to the kernal, to enter run level 1, but i notice that this way not work with Ubuntu and some other distributions.

In my opinion, this way is reduce security in OS, and we can do the same thing by live CD, so i want to tell me what's your opinion about that?
Thanks );

you need physical access to the box to boot and change root pass so i don't see a security risk, one way to fix this is to use encryption to encrypt your workstation, they will need your pass-phrase to mount the HDD, the down side is you have to type that after each reboot, from the keyboard

That would be better answered in an Ubuntu forum.

You can also put a password on Grub, so that you can boot the system normally without a password, but you need to enter the password in order to change anything, such as changing the options to enter runlevel 1.

Of course, if you're going to do this, you'll need to remember the Grub password in order to reset the root password.
