Network UPS Tools

Network UPS Tools (also known as NUT) is an extremely powerful and versatile client/server based approach to UPS monitoring. Products from a wide range of vendors (APC, Belkin, Best Power, MGE, Tripp-Lite, etc.) are supported. A shared UPS can be monitored by one host, notifcations being sent to the other hosts via authenticated TCP connections. A Web interface is available, as is a Windows client.

Recent releases

  •  14 May 2014 00:49

    Release Notes: This version includes both a number of driver additions and some cleanup of old code. A new driver, "nutdrv_atcl_usb", was added. The snmp-ups driver now supports the XPPC-MIB. A fallback sub-driver was added to nutdrv_qx to support Q1 protocol UPSes. FreeBSD devd.conf files are generated to automatically change ownership of supported USB UPS device nodes to match the configured NUT username. Since the FreeDesktop.org Hardware Abstraction Layer (HAL) has been deprecated, the NUT HAL support has been removed.

      Release Notes: This is the first release after the transition from Subversion to Git. NUT can now be configured to use either OpenSSL or Mozilla NSS for securing client-server connections. Many drivers have been updated, including extensive rewrites of the bcmxcp and apcsmart drivers. The nutdrv_qx driver is a more flexible successor to the blazer_ser/usb drivers, and now handles the Voltronic protocol. The new apcupsd-ups driver is a bridge to Apcupsd NIS servers. Tripp Lite has provided extensive compatibility information and testing results for their USB PDC HID models.

        Release Notes: This release fixes a regression in upssched and introduces support for a few more devices. It also contains a new implementation of the mge-shut driver. Support for several new devices was added. This release also includes a new meta-driver, macosx-ups, which monitors any UPS which integrates with the Mac OS X Power Sources subsystem (Energy Saver control panel). The set of monitored variables is limited, but further development is planned.

        •  23 Aug 2012 02:58

          Release Notes: This release fixes an important vulnerability in upsd (CVE-2012-2944: upsd can be remotely crashed). A static source code analysis has been performed using Coverity, and 12 issues were fixed. New "LIST CLIENTS" and "NETVER" commands were added to the NUT network protocol. The developer guide's "Network protocol information" section was updated with information. Support for many new devices was added. Improvements were made to the apcsmart, bcmxcp, bestfortress, blazer_*, newmge-shut, oneac, snmp-ups, and usbhid-ups drivers.

          •  15 Jan 2012 17:36

            Release Notes: This version adds support for Cyber Power Systems hardware with SNMP RMCARD, Dynamix 650VA USB, LDLC UPS-1200D, Tecnoware UPS ERA LCD 0.65, Powercom BNT-xxxAP (USB ID 0d9f:0004), and various USB devices using UPSilon 2000 software. The nut-scanner tool has been modularized even further, dynamically opening libraries for features such as USB, IPMI and SNMP. HP/UX packaging and AIX compilation have been improved. Additional bugfixes for various drivers (including blazer_usb with invalid USB vendor IDs 0000 and FFFF) are noted in the NEWS file and ChangeLog.

            Just to confirm, the NUT website is indeed www.networkupstools.org, and the mailing list page on Alioth should work to get in touch with the developers. If anything appears to be down in the future, and you can't contact us via the mailing lists, you could also try to reach us via the freshmeat "Report problem" link above.

            Links still broken - 2008 Jul 24
            I'm not sure that http://www.networkupstools.org/ is the correct URL either. Although it does go to a site, the links there are broken. All the e-mail contacts on there and the author listed here on freshmeat.net for Network UPS Tools don't bounce or response. The mailing list page dosen't work either so there's totally no way to contact anyone.

            PS: I've been trying to resolve this for a week and with no results.

            web page link is outdated
            The web page link shown for this project should be updated to the current link. The link shown for this project in the freshmeat pages is http://www.exploits.org/nut/ but that should be changed to the new page at http://www.networkupstools.org/
