(None) Login

Hi,

I was just messing around with CentOS  and now when I boot it, it prompts (none) Login: I tried root and every user but none works, I know root password isn't changed.

I even tried to boot into single mode, but it prompts the same thing and wont boot.

It's a test box (VMware), so I can do anything with it, there is nothing to worry about data lost. But I need to know how to fix it.


Any advice would be much appreciated.

Thanks

Try entering the grub config and editing the kernel line to have "init=/bin/bash" on the end.  Then do the following:

mount -w -o remount /
passwd root

Then run:

sync;sync;sync
shutdown -r now

That should let you back in.  You may have nuked config files in /etc though if the hostname is none.  In that case you may have other issues.

Uh oh - your system has a serious issue.

Can you try init=/bin/sh and see if that works?  If not, try booting an ISO image of a rescue CD (RIP Linux is a good one) and see what /bin looks like.
I'm logged in in rescue mode and chrooted the sysimage but don't know what else to do now as I can't change the pasword.

Did you accidently blow away /bin on the target machine?

:D

I didn't accidentally the whole machine, I did it on purpose.

Basically, I'm preparing for RHCE exam and  I found a tool on internet which could mess things up for you and then you have to fix it. the tool is: rhce-ts-5.0.0-7.noarch.rpm and I found it on thepiratebay.org

The command which does this is: "tsboot 3" and when I boot the machine it prompt (none) login:

I tried the same command on another vm machine and same thing happened. But here is a little clue. The moment I run the above command (to screw things up) and check the logs I find http://i.imgur.com/14R5m.png (check the red circle) When I try to shutdown the computer after the command it doesn't shutdown properly.
