I use the Ubuntu 'apcupsd' package with an APC Smart UPS (their cheapest model that is supposed to output nice, non-square AC waves). I think mine came with a USB cable, but I opted to use the 9-pin serial cable since my server had a free serial port. In addition to clean shutdowns based on realistic runtime calculations by the UPS, one thing I really like is that apcupsd emails me when the power goes out or comes back on. My broadband modem and AP are also on a UPS, so I pretty reliably get emails/texts when there's a power problem. Since my house relies on a sump pump to keep the basement dry, this is a big relief. I also like that the Smart UPS handles under- and over-voltage events. I've been pretty loyal to APC ever since I had a great customer service experience with them in the late 1990s, but next time I'll probably shop around, as I've had some bad experiences with APC units' reliability lately both at home (the unit that preceded my Smart UPS) and work (some nicer rackmount units) -- though most of the APC units, including one I've owned more than a decade, work fine. -- peterw http://www.tux.org/~peterw/ Free plugins: 'AllQuiet' (http://www.tux.org/~peterw/slim/AllQuiet.html) 'Auto Dim/AutoDisplay' (http://www.tux.org/~peterw/slim/AutoDisplay.html) 'BlankSaver' (http://www.tux.org/~peterw/slim/BlankSaver.html) 'ContextMenu' (http://www.tux.org/~peterw/slim/ContextMenu.html) 'DenonSerial' (http://www.tux.org/~peterw/slim/DenonSerial.html) 'FuzzyTime' (http://www.tux.org/~peterw/slim/FuzzyTime.html) 'KidsPlay' (http://www.tux.org/~peterw/slim/KidsPlay.html) 'KitchenTimer' (http://www.tux.org/~peterw/slim/KitchenTimer.html) 'PlayLog' (http://www.tux.org/~peterw/slim/PlayLog.html) 'PowerCenter/BottleRocket' (http://www.tux.org/~peterw/slim/PowerCenter.html) 'SaverSwitcher' (http://www.tux.org/~peterw/slim/SaverSwitcher.html) 'SettingsManager' (http://www.tux.org/~peterw/slim/SettingsManager.html) 'SleepFade' (http://www.tux.org/~peterw/slim/SleepFade.html) 'StatusFirst' (http://www.tux.org/~peterw/slim/StatusFirst.html) 'SyncOptions' (http://www.tux.org/~peterw/slim/SyncOptions.html) 'VolumeLock' (http://www.tux.org/~peterw/slim/VolumeLock.html) ------------------------------------------------------------------------ peterw's Profile: http://forums.slimdevices.com/member.php?userid=2107 View this thread: http://forums.slimdevices.com/showthread.php?t=80889 _______________________________________________ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss
