You can get it at > http://www.exploits.org/nut/ If I may offer one piece of obvious (but unfortunately anecdotal) advice: when controlling the shutdown of multiple machines from one UPS monitoring device, remember to ensure that the communication between them will work in the event of a power outage. This means either serial cables or make sure your hub/switch is plugged into a UPS too :-) jan (had a DOH moment - fortunately it only took down a news server) PS. I don't think splitting the signal will work; as I understand it there are a number of request/response mechanisms for getting performance details off the UPS. I don't think a split serial signal will work in that case. -- jan grant, ILRT, University of Bristol. http://www.ilrt.bris.ac.uk/ Tel +44(0)117 9287163 Fax +44 (0)117 9287112 RFC822 jan.grant@bris.ac.uk Whenever I see a dog salivate I get an insatiable urge to ring a bell.
