Re: Root account desactivated

HAHHAHAHAHA .....

Take a slackware CD, boot from it. You will end up a command prompt. Now
type the following commands as shown, if it fails use a Win2k CD and
follow the on screen instruction.

root <ENTER> = logs you in as root
mount /dev/hda2 /mnt = replace /dev/hda2 with the drive and partition
that the RH /etc directory is on. It not sure you can try
/dev/hda1,/dev/hda2,/dev/hda3 and so on ....

cd /mnt/etc
vi passwd

vi commands:
i = allows you to insert text
x = like delete in command mode
ESC = enter command mode
q = exit
q! = exit a modified file
wq = exit and save a modified file

Once you are done, unmount the drive:
umount /mnt
reboot

That should fix the problem, now change the root password.

Michael.

Hi community!

I have a really stupid trouble: on a Redhat 9.0, the line matching
the root account in the file /etc/passwd has been changed from
".../bin/bash" to".../sbin/nologin". We have the root password, but
when performing a "su" command, the system replies that the account
is not currently available.

So the question is: how from an user's account and knowing the
root's password but having the root account disabled can we
reactivate this root's account?

Any suggestion would be appreciated, I do not want to reinstall the
box :(

Thanks a lot in advance!
