Cheap UPS's from CompUSA cost in the $70 range and are far superior to surge suppressors, and will save you hours of time repairing a trashed system if you use them properly. >How about these: > >/usr/ports/sysutils/upds > First of all, this is upsd, not upds. However, more importantly, this daemon program is hard-coded to work on the EUROPEAN 220v standard, not the AMERICAN 120v. As a result, if you try to run it with a US UPS, it will shut the server down complaining about undervoltage. Doug White modded this about 3 years ago for 110v power, his is at http://resnet.uorgon.edu/dwhite/upsd-2.0.1.6.1.tgz you may need to modify this to get it to compile. > >/usr/ports/sysutils/bkpupsd > This one works OK on a Back-UPS but I've found results less than stellar with a SmartUPS+Dumb cable. Frankly, though, the second one is overkill if all your going to do is this. Tying a dumb UPS like this to a computer is extremely simple, and in fact you don't even need a UPS that has a sense port on it. All you need is a serial port, a 110v relay and a shutdown script that blocks on a serial port waiting for carrier detect. I discuss this in my book.
