Hi,
Probably I framed the question badly, so everyone has misunderstood
what I asked. I am not at all interested in reinstalling or
preventing my friend from doing what he wants. I wanted to know what
he may have possibly setup so that he can become root any time, so
that I can do the same. And I wanted to know how it can be reversed,
so that my own system is protected from such attacks.
Thanks.
Anindya.
