Hi,
Seeing the recent mention of UPS (on the thread "Of software RAID on SUSE Linux") a question came to mind:
If you have multiple computers, how does one get them to all initiate the desired actions when main power fails and the UPS takes over?

You first set up the machine that is physically connected to the UPS. Then you set it to be the "master" to serve one or more other machines over ethernet. Then you set up each machine to take info over your local ethernet from the "master". You will need to run the ups daemon on each machine of course. I use apcupsd as I have an APC ups. (They changed the schema from "master/slave" to a different model, don't recall the details but can send this to you when I get home if you need it, but the idea is the same). I have my ups connected to my server, of course, and have one other opensuse machine getting power info from that one. I have the server set up to stay on for max time before the batt goes out. I have the other workstation set to shut down 5 minutes after power loss. This keeps this machine up during short outages, but gives my server max up time on batt if its a long outage. There is another more generic daemon for ups called Nut. I've not used that but have looked at it in the past. I know this is light on details, but can give more later if needed.
