----- Original Message ----- From: "Doug White" <dwhite@resnet.uoregon.edu> | 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 :) Does any of the UPS stuff on FreeBSD do it securely? It seems like it would be safer for a client machine to poll the UPS-monitoring server for power status vs. having the monitoring server alert its clients to do something like shut down. On the more sophisticated end you could do it as an SNMP trap, or you could just write the UPS status to a file on the monitoring box and the clients could fetch the status periodically and make their own decisions about what to do when the power went off.
