problems with command su

Hello, I'm new user in linux community. I have installed in my computer
mandrake linux 10.0

Sometime ago it was working normal without problems. After that I changed the
root password, always that I want to change something in the configuration of
the system, I run su from other user (vladimir).

But the system says 'invalid password'. I tried the old, and new password, but
it doesn't work

I have to logout, and login with root to change some configurations.

Anyone could help me!!

thank you

Vladimir

Re: problems with command su

Hi,

when you are at the LILO bootloader prompt type
single as an argument to the kernel.
after it boots , type passwd to change your password.

should work, try it out and tell us...

The same should work on grub as well,
there is an option to edit kernel parameters before booting.
try it out.

regards,
Joy.M.Monteiro

Last time I had to unlock a box, I booted into Knoppix, mounted the root fs, and
deleted the root password in /etc/shadow. In about 3 minutes. Scared the scat
out of the guys watching me.

Just make sure you fix the permissions both before and after - /etc/shadow is set
at 0400 and vi will gripe.
