NUT.CONF(5)

===========

NAME
|
|
----
|
|
nut.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.
|
|
|
|
IMPORTANT NOTE
|
|
--------------
|
|
|
|
This file is intended to be sourced by shell scripts.
|
|
You MUST NOT use spaces around the equal sign!
|
|
|
|
Refer to the EXAMPLE section for illustrations.

|
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 linkman: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 linkman: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.

INTEGRATION
|
|
-----------
