I think NUT is the more complicated product, but it also works in a multiserver environment (though I never made it that far in my configuration). In any case, the NUT documentation has good suggestions for how to test your configuration, which I used (generically) even when testing apcupsd. I currently use apcupsd in a single-machine environment, and have it configured to shut down on low battery. I tested almost all the scenarios described in the NUT docs, and apcupsd performed fine in all of them. (One thing I didn't test was whether it restored power gracefully if line power was restored after shutdown had already began; if you are concerned about availability you should do this test in addition to the more obvious ones.) --keith -- kkeller at speakeasy.net -------------- next part -------------- A non-text attachment was scrubbed...
