also if you are certain you've rebooted (eg, little reset button or perhaps power cycle) there's much less chance that preceding person using the same terminal has left something lurking (such as a fake login screen for instance, which UNIX has had almost from the beginning)
Yah, now you're just trusting the bios, the local disk (if any) and the network. Much more secure ;-) Tim Newsham http://www.lava.net/~newsham/
