NUT.CONF(5) NUT Manual NUT.CONF(5)NAMEnut.conf - UPS definitions for Network UPS Tools
DESCRIPTION
This file attempts to standardize the various files being found in
different installations, like /etc/default/nut on Debian based systems
and /etc/sysconfig/ups on RedHat based systems.
Distribution’s init script should source this file in order to
determine which components have to be started.
Blank lines are ignored. Lines with a hash (#) character at the 1st
position of the line are ignored, too. They can be used to add
comments.
DIRECTIVES
MODE
Required. Recognized values are none, standalone, netserver and
netclient. Defaults to none.
none
Indicates that NUT should not get started automatically,
possibly because it is not configured or that an Integrated
Power Management or some external system, is used to startup
the NUT components.
standalone
Addresses a local only configuration, with 1 UPS protecting the
local system. This implies to start the 3 NUT layers (driver,
upsd and upsmon), with the related configuration files. This
mode can also address UPS redundancy.
netserver
Like the standalone configuration, but also possibly need one
or more specific LISTEN directive(s) in upsd.conf. Since this
MODE is open to the network, a special care should be applied
to security concerns.
netclient
When only upsmon is required, possibly because there are other
hosts that are more closely attached to the UPS, the MODE
should be set to netclient.
UPSD_OPTIONS
Optional. Set upsd specific options. See upsd(8) for more details.
It is ignored when MODE above indicates that no upsd should be
running.
UPSMON_OPTIONS
Optional. Set upsmon specific options. See upsmon(8) for more
details. It is ignored when MODE above indicates that no upsmon
should be running.
POWEROFF_WAIT
Optional. At the end of an emergency system halt, the upsmon master
will signal the UPS to switch off. This may fail for a number of
reasons. Most notably is the case that mains power returns during
the shutdown process. See the section "Power races" in
/usr/share/doc/nut/docs/shutdown.txt.gz. The system will wait this
long for the UPS to cut power, and then reboot. It should be long
enough to exhaust the batteries, in case line power continues to be
unavailable. On the other hand, it should not be so long that the
system remains offline for an unreasonable amount of time if line
power has returned. See sleep(1) for compatible time syntax. If you
specify the time in seconds, use the "s" suffix.
Warning
this workaround might be dangerous under some circumstances. Please
read http://bugs.debian.org/358696 for more details.
EXAMPLE
# /etc/nut/nut.conf. See nut.conf(5)
MODE = none
UPSD_OPTIONS = ""
UPSMON_OPTIONS = ""
# POWEROFF_WAIT = 15m
INTEGRATION
An init script, such as /etc/init.d/nut, is expected to source this
file in order to determine which component(s) has to be started.
