Fedora Core 3 & Core 4 Password questions

Is there any length of complex password that can be assigned to the ROOT
that cannot be hacked if the person hacking has console access? I am selling
a software product that I do not want the users to have access to. The only
account on the server will be ROOT. I wanted to use a password 32
characters/numbers/symbols or higher. Main thing is no one must get in.

Console access? Why bother hacking when there are quite obvious ways
around it from that point.

Then don't install it on the users hardware, or hardware that the users
have access to.

With the modern MD-5 hash system, this is easy - after all, you want to be
the only person with root, so you can set the password as you like. Of
course, it only takes a few minutes AT MOST to bypass this.

Physical access beats five aces. If you want the system to be totally
secure, encrypt the drive, and require the password to be entered each
time the system boots. You can't keep the password on the system, or
allow it to be entered over the network, as either method can be compromised
very easily. Not practical, you say? Neither is your desire to prevent
anyone from accessing the software.

Old guy is right on this one. If you don't control the hardware, the
software can be retrieved.

Passwords make no difference, the disk directly accessed and software
copied as simply as inserting a CD (for example) with the OS that mounts
the disk where one knows the password.

One can just dupe the disk and one can hack the copies to their hearts
content while still using the original copy. The system manager may not
even be aware this copying has occurred, it takes only a few minutes.

Even if you use hardware keys (there are several flavors on the market).
Someone who has enough patience can work their way through the locks.
You may slow them down, but in the end it will be accessed.

There are several other viable approaches, but if you are relying on a
password to lock the OS down, to protect you, forget it.

You mean like those old dongles that you used to have to attach to the
parallel port? Yuck!

Copy protection schemes have been around since before IBM introduced
the PC in 1981. This ranged from the above noted hardware dongles, to
requiring the floppy or tape which used a strange format, to a "hidden"
disk file in a hidden directory, or even recording exactly where (track,
sector, and head) some file was put on the disk... you name it, it's
been tried - maybe even before you were born - and it did not work then.
Want to put it on a USB or Firewire device? Want to think that differs
from what has been done before?

Everyone is right on this - if your users have physical access to the
machine, all it takes is a Linux boot disk and a chroot command to
change the root password anyway. If you are really hardcore, you need
to encrypt the harddrive and have people enter a password every time the
system is booted. That, and make sure the hardware is locked and
physically secure. If you really want to do this, I would recommend a
program called loop-aes. It's somewhat difficult to use, but if setup
properly, can be VERY secure.

Good luck,
