Secure attention key for Linux login...

[Kevin Cowtan]

Hi!

I'm worried about the possibility of spoofing login screens under 
Fedora to grab passwords. This has been addressed by the kernel 
developers a long time between 1996 and 2001, but doesn't appear to 
be set up, at least in FC2 (unless the key sequence is not 
ctrl-alt-pause).

For more information, see these pages:

http://www.linux.com/howtos/Secure-Programs-HOWTO/trusted-path.shtml

The kernel code is in the tree:
grep SAK /usr/src/linux-2.6.5-1.358/drivers/char/keyboard.c

Is there an easy way to enable this under Fedora, or will I need to 
recompile the kernel?

Thanks,
Kevin Cowtan
