Is there such a thing as a normal root and a real root in Unix/Linux?
I am doing a buffer overflow project (in Ubuntu 11.04) and I invoke /bin/zsh and /bin/bash separately. In both cases
$whoami returns root
$id returns uid=1000, euid=0, gid=1000.
But, when I try to run
to change some user's password, the shell returns:
passwd: You may not view or modify password information for username
Is there something that I am missing here as I believe this is root does not have low level privileges. I have searched all over the net, but I don't seem to find a comprehensive answer.
