Description

For this assignment, you are to add a backdoor to Minix as a hacker would do.

Install the necessary two virtual machines to do cross-development of Minix. This is in a separate handout. Make sure it works and that you can boot the Minix VM from the generated ISO file.

Take a quick look at ./minix/kernel/main.c and if you really followed the instructions in the first handout for installing Minix, there ought to be your printf statements in the announce function. 

Your job as a hacker, is first to observe. So in /minix/kernel/main.c if you skip down a ways (or search for it) you will see a function named panic. This function prints whatever is in the string, using printf-style formatting, then completely stops the operating system and reboots. Perfect for a hacker.

What we want to do is insert a secret trigger, a command that, when run, will call panic from within Minix. Now, when I enter a command like foo, the shell will loo
