Y'know Unix is generally a pretty secure operating system. Well, across a network anyway.
Unfortunately (or fortunately, depending on your angle) the system is very vulnerable if someone in the know has access to the console.
So here's how to
hack a Unix box get your root password back when you've forgotten it..
On recent versions of Unix, select 4. or Boot in single user mode. At the default command prompt (# ), you will be prompted for a default shell /bin/sh, press ENTER
Mount the file system:
mount -t ufs -a
You now have system wide access without even supplying a password. Feel free to change root's password
or make a new system administrator username or browse the directory tree. Scary..
