If you have a user account on a liinux box for this purpose called user, and you're not running pam a line like root:user:NOPASS in /etc/suauth chmod 600 /etc/suauth once saved may provide you with some security benefits. When you next type su - <cr> after you've rebooted you'll read a message saying password authentication bypassed if you were user at that time and you will have full root privileges and root's environment. The security benefits come as a result of computer crackers installing packet sniffers to capture passwords. So if you install a new system and use new passwords and make your /etc/suauth file and reboot before you go onto the internet for the first time, all thoose packet sniffers will ever see is password authentication bypassed each time you become root. Very frustrating for computer crackers, but then again who better deserves to be frustrated?
