I'm trying to force the software to properly shutdown the computer 
when someone (admin) over the internet reboots the UPS (don't ask me 
why, we simply sometimes must to do it) - for example from the UPS's 
web interface or from the telnet's command line. We use many APC UPSs 
like 750XL or Matrix.

It happened somehow accidentally, that the admin reboots the UPS and 
forget to shutdown the server before shutdowning UPS and the computer 
  sometimes doesn't start properly again.

When we are using Nut driver apcsmart (monitoring over serial port), 
the driver works fine = when gracefully rebooting UPS over internet, 
the driver says to the computer it shlould shutdown. When we are using 
snmp-ups driver (monitoring over IP address), the snmp-ups driver does 
not says to the computer it should shutdown when we are gracefully 
rebooting UPS and bad things will happen...

What idea do you have?
