what is the different of both? –  klox Sep 18 '10 at 2:12
    
apcupsd is for APC brand UPSs. upsd is for any compatible serial-port UPS. –  Dennis Williamson Sep 18 '10 at 2:35

NUT is also a useful UPS package. It's also flexible configured to monitor remotely and to monitor multiple UPSes and shut down multiple servers in a network.

Its drawback is that it can be difficult to set up properly. Single systems with one attached UPS can be set up fairly easily, as long as you pay careful attention to the instructions.

Newer versions of gnome-power-manager have support for certain brands of UPS and expose shutdown options via its preferences.
