# genpowerd(8)

UPS monitor daemon

## 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.
