The problem with this is doing it securely. You can have one monitor machine but having some automated way of telling the others to shutdown that can't be tricked is a tough problem. ssh with a null-passphrase RSA key is about as close as you can get, but that doesn't keep root on one machine from telling the others to shutdown, but that may not be a problem in your environment :) Doug White | FreeBSD: The Power to Serve dwhite@resnet.uoregon.edu | www.FreeBSD.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
