Hi,
The following problem may be trivial to some of you, however my
knowledge of linux is limited, and I dont understand how can it be
done.
In our institute, we use Debian Linux, and the boot loader is lilo.
For those machines where the lilo password is not set, ANY ONE can
get a root shell by simply interrupting the boot process and typing
linux init=/bin/sh in the boot prompt.
One of my friends obtained a root shell in this manner, and has
either made some changes, or set up some program, by which he can
become root any time, without acutally knowing the root password,
which is known only to our system administrator. What may be the
possible things he has done to setup his program, and how can it be
reversed ?
Thanks in advance.
Anindya Mozumdar.
