Hello all,
When I try the command #mount -o remount,rw / it was executed successfully but when I type passwd it is throwing me an error message “passwd: user not known to the underlying authentication module” Please guide me on what to do next.

Regards,
Blue

still good for opensuse 11.1 also…

actualy this procedure should be okay for just about any linux that boots from GRUB or LILO.

@Ellevi: for protecting a notebook, you essentially need to protext the data on your harddrive from being read by any operating system (once someone has your PC, there’s nothing to stop them cracking open the box taking out the drive and putting it in their own machine).

Take a look at openSUSE’s hard-drive encryption tools, and the hard-drive encryption how-to. For something really secure, you’re going to have to store the encryption key on a removable medium kept separate from the notebook and enter a passphrase each time you boot. There is no other way for the truly paranoid…

My work (big IT company) uses Pointsec for PC (Windows XP) — it decrypts the drive upon boot and relies on Windows security to avoid reading the drive unless you can log into Windows. It’s good enough, but not fool-proof either, since there are ways to bypass Windows security too…

I agree with Michael and Richard until the scenario is an opensuse system on a well guarded server.
But what about an opensuse on a notebook that can easily be lost or stolen?

If you need additional security against physical attacks at boot time, then GRUB allows you to set a boot loader password, which prevents settings from being changed.

That way you will have to boot from a CD and reset that first, but you can prevent that as well by using a BIOS password. Then you have to physically get inside the machine and remove the battery to reset that.

Since the reset is done at boot time, you would have to have physical access to the machine to be able to perform this task. So security is still unaffected, unless you leave your front door open:)
