I've installed everything from sources (NUT 2.0.1) on freebsd 5.4 and it detects the ups, it tells me about the voltages etc. When the battery charge reaches certain level it tells me that the battery is low and the system will shutdown but nothing happenes. In logs I can only find: upsmon[386]: Executing automatic power-fail shutdown upsmon[384]: Unable to call shutdown command /sbin/shutdown I don't have a clue what could be wrong.... Anyone could help me ?? Cheers, Greg
