Martin - Can you bring the machine down? I would suggest passing init=/bin/sh to the system at LILO boot (granted you are using LILO - I don't use GRUB, but if you do, I'm sure there's a similar switch), mount partitions accordingly, and use your editor of choice (be very careful, I think that goes without saying), and edit the line accordingly. On some of my personal machines at home, I've been fortunate/dumb enough to leave another console logged in as root, and I could fix a problem like this by switching to one of those logged in consoles and did what I had to do, that way. Perhaps you have physical access to this machine and can do the same thing? Hope that helps -dant On Thu, 2004-03-11 at 15:50, sil wrote:

Bnoni wrote: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! _________________________________________________________________ MSN 8 with e-mail virus protection service: 2 months FREE* http://join.msn.com/?page=features/virus --------------------------------------------------------------------------- Ethical Hacking at the InfoSec Institute.
