That's why I did this yesterday. In MS-DOS days, Ctrl-Alt-Del did boot the machine, and so you learned to avoid it. But on Windows NT, it's the secure attention signal, used to log in and out of the system (and to get the system's attention if something goes terribly wrong), so you are using it regularly. The first time I did this on FreeBSD and the system instantly booted, I was quite surprised to say the least. I've fixed that now. In this case, it doesn't stop malicious persons, but it prevents a lot of accidents. Had there been 200 people on the machine when I pressed Ctrl-Alt-Del, I would have been very unhappy. ----- Original Message ----- From: "Lamont Granquist" <lamont@scriptkiddie.org> To: "Bart Matthaei" <bart@dreamflow.nl> Cc: <freebsd-security@FreeBSD.ORG> Sent: Friday, November 09, 2001 08:26 Subject: Re: reboot,ctrl+alt+del,shutdown > > If you extend security to include security from accidental mistakes then > this most certainly does become appropriate.
