There are several How-To's out there on encrypted root file systems and encrypted swap (DON'T FORGET TO ENCRYPT YOUR SWAP!) Burn a bootable CD-Rom with your boot system. Store the key to your file systems on a USB key which you remove after booting. [Alternative, on systems which can boot from USB, burn it all to the USB key.] Now, nobody can simply reboot your PC for any reason without having that USB key. At least, if they boot it off a bootable CD, they still can't read the hard drive. Then you just have to make sure they can't log into the running system or switch to S from a running system. You still need to worry about stuff like hardware keyloggers and other nasty hardware stuff that people MIGHT install if they think you're being cheeky with all this stuff. You might tempt someone to show you up. :-) > thanks > ankit Mike > ________________________________________________________________________ > Yahoo!
