The nethserver-nut package provides: * Network UPS Tool (NUT) configuration * web UI for simple configuration * optional collectd support

The package provides two configuration modes:

• Master: a master node is a machine directly connected to the UPS port
• Slave: a slave node is a machine connected to the master via tcp

If you need stand-alone mode, just configure the machine as master.

A master node receives events from UPS, sends events to slaves and takes decisions (eg. power off the machine).

DB properties:

• Mode: master
• Device: UPS port, can be a device like /dev/ttyS0 or auto if the UPS is USB
• Model: UPS driver name selected from :file:`/usr/share/driver.list`
• Description: UPS model description like "APC - Smart-UPS USB (**)" (used only on web UI)
• Password: chosen password to communicate between master and slaves
• Ups: ups name, default is UPS
• User: upsmon user name, default is upsmon
• Notify: if enabled notifications about UPS events are sent to the admin user, default is disabled

The password is generated during first installation from the :file:`nethserver-nut-conf` action.

A slave node receives events from a master and takes decisions (eg. power off the machine).

DB properties:

• Mode: slave
• Master: host name or ip address of master node
• Password: chosen password to communicate between master and slaves
• User: upsmon user name, default is upsmon

If server is in master mode, collectd is configured to monitor the local connected UPS.

Optional package required:

• collectd-nut
• nethserver-collectd
