genpowerd - UPS monitor daemon
/sbin/genpowerd [ -k ] tty ups-type
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.
Serial-Device
Some serial port that is not being used by some
other device, and does not share an interrupt with
any other serial port.
UPS-Type
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.
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.
Unipowerd does not use environment variables.
- /etc/powerstatus
- indicates line power status
- /etc/upsstatus
- indicates UPS battery status
- /etc/genpowerfail
- script to manage power failures
Well, not a real bug but genpowerd should be able to do a
broadcast or something on the ethernet in case more Linuxboxes
are connected to the same UPS and only one of them
is connected to the UPS status line.
shutdown(8), wall(1), init(8), inttab(5).
