There should not be a way to fix this without root access or by booting the machine with an alternate configuration. If there is, then we are in deep trouble. Markus

Hmm, /bin/false is 0755 and belongs to root.
I also cant scp the passwd back and overwrite the existing passwd (permission denied).
And im not trying to hack someone else system. Actually its not my System, but the one who owns it asked me to help him.
OK, here is a short overview about my permissions: - I do have normal user access to the system. - I am in the admin group (gid 500, normal usergroup). - I do have the root password (and my user password of course). - I do not have any physical access to the System.
Hi,
here would be a workaround: mv /bin/false /bin/false.TEMP ln -s /bin/bash /bin/false echo "/bin/false" >> /etc/shells login as root chsh root set it to /bin/bash *undo /bin/false: rm /bin/false mv /bin/false.TEMP /bin/false *done
Regards, Alin.

Hello All,
Ive got a big Problem. I changed the root shell to /bin/false.
There is neither a user in the sudoers nor is there any other root-user or even a user in the root group.
Is it possible to switch back the shell to /bin/bash or sh or something?
Ive tried: sudo -- not in sudoers su -s /bin/bash -c "command" -- "using restricted shell: /bin/false"
thanks in advance, Ulrich
