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\&.
|

.sp

Distribution\(cqs init script should source this file in order to determine which components have to be started\&.
|

.sp
|

Blank lines are ignored\&. Lines with a hash (\fI#\fR) character at the 1st position of the line are ignored, too\&. They can be used to add comments\&.

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\&.

.RE

standalone
|
|
.RS 4
|
|
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\&.

.RE

.PP

netserver
|
|
.RS 4
|
|
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\&.
|
|
.RE
|
|
.PP
|
|
netclient
|
|
.RS 4
|
|
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\&.

\fBPOWEROFF_WAIT\fR
|
|
.RS 4
|
|
Optional\&. At the end of an emergency system halt, the upsmon primary 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/FAQ\&.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\&.
