history

Project history and usage

Network UPS Tools, packaged as `nut`, is the standard open-source toolkit for monitoring and controlling UPSes, PDUs, automatic transfer switches, power supplies, and related power devices through a common protocol and driver/client/server architecture.

Project history

The official NUT release notes trace the project back to Russell Kroll's 1996 APC Smart-UPS experiments, including cron-driven status reports and early protocol tests. Smart UPS Tools 0.10 was publicly released on March 10, 1998; a June 5, 1999 rewrite separated drivers, server, and clients; and the project renamed itself Network UPS Tools with 0.42.0 on October 31, 1999 to reflect multi-vendor support and avoid APC trademark proximity.

Adoption history

NUT grew from one APC-focused monitor into a cross-vendor power-device layer. The official site said on July 1, 2026 that at least 197 manufacturers and 1,431 device models were known compatible. Its user manual says NUT is pre-packaged for many operating systems, embedded in storage, automation, and virtualization appliances, and often shipped as companion software by UPS vendors.

How it is used

A normal deployment has device-specific drivers feeding `upsd`, clients such as `upsc` querying status, and `upsmon` coordinating graceful shutdown before battery exhaustion. Package users care about config files such as `ups.conf`, driver startup through `upsdrvctl`, network access control, port 3493, and matching the driver to the exact UPS/PDU hardware. Larger deployments use the network model so multiple hosts powered by one UPS can observe the same state and shut down together.

Why package nerds care

NUT is operational plumbing: boring until power fails, then essential. It is packaging-heavy because it touches USB, serial, SNMP, Modbus, OpenSSL, init/service managers, CGI clients, Python/Perl/C/C++ client libraries, device rules, and OS-specific paths. RFC 9271, published in August 2022, documents the UPS management protocol used by the NUT ecosystem and reinforces that the project is more than a single Unix daemon.

Recommended review

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.
