[Nut-upsuser] Unconventional Setup

Hi,

We have a server rack with two UPS'. The servers in the rack are split 
into Windows network and an network of BSD and Linux machines behind a 
OpenBSD firewall. All machines have redundant PSU's and are connected to 
both UPS'.

The Windows administrator wants to use APC Parachute application to 
monitor the UPS' and write scripts to shutdown the windows machines.

The question is how to shut down the non windows machines on power failure.

Looking at the NUT documentation I'm thinking that I could set up a 
dummy-ups driver on the OpenBSD firewall along with the other daemons 
needed to shut down the machines.

Then write a script, which Parachute will run, which will ssh into the 
OpenBSD firewall and execute 'upsmon -c fsd' to trigger the other 
machines to shut down.

Does this sound like a workable/sensible way forward?

Many thanks
