NAME

genpowerd - UPS monitor daemon

SYNOPSIS

/sbin/genpowerd [ -k ] [ -c configfile ] [ -d upsport ] [ -r rcpowerfail ] [ -s upsstat ] [ -t upstype ]

DESCRIPTION

Genpowerd monitors the serial port connected to an UPS device and will perform an unattended shutdown of the system if the UPS is on battery longer than a specified number of minutes. Genpowerd needs to watch a tty with modem control properties, and [wiring details to be added.] Please refer to the genpowerd documentation for further information.

ARGUMENTS

configfile

Path to the configuration file genpowerd.conf . This file contains UPS type definitions, and may also containts default parameter assignments.

upsport

Some serial port that is not being used by some other device, and does not share an interrupt with any other serial port.

rcpowerfail

Path to the rc.powerfail script, which is executed when a power event occurs. The name of the event is passed as the only command line argument to the script, and also written to the upsstat file.

upsstat

Path to the upsstat file, where the name of the current power event is written.

upstype

A text string identifying the UPS and cable combination that genpowerd is to monitor. If genpowerd is envoked without any arguments, a list of available configurations will be displaied.

OPTIONS

genpowerd has the following command line options:

-k

Causes genpowerd to send the signal to kill the UPS's inverter. This signal is configured at compile time in the genpowerd.h header file, and selected by the UPS/cable configuration selected at runtime.

ENVIRONMENT VARIABLES

Unipowerd does not use environment variables.

FILES

genpowerd.conf         configuration file

upsstat                        indicates UPS battery status

rc.powerfail           script to manage power failures

powerstatus            indicates line power status (Linux only)

BUGS

Well, not a real bug but genpowerd should be able to do a broadcast or something on the ethernet in case more Linux-boxes are connected to the same UPS and only one of them is connected to the UPS status line.
