2. NUT Release Notes (and other feature details)
If you’re upgrading from an earlier version, see the UPGRADING.adoc file.
Please note that web and source document links, product and service names
listed in historic entries of past releases may no longer be relevant.
For a complete and more detailed list of changes, please refer to the
ChangeLog file (generated for release archives), or to the Git version
control history for "live" codebase.
2.1. Release notes for NUT 2.8.1 - what’s new since 2.8.0
https://github.com/networkupstools/nut/milestone/8
-
"UPS management protocol", Informational RFC 9271 published
by IETF at https://www.rfc-editor.org/info/rfc9271 and the
IANA port number registry was updated accordingly at
https://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xhtml?search=3493
(even though this RFC is not formally an Internet Standard)
-
NUT documentation files were rearranged, renaming some to
*.adoc pattern
to facilitate automatic rendering in GitHub and IDE GUIs, and adding recipe
support for GitHub issue/PR links. This NEWS file is now proper asciidoc
rendered into release-notes.pdf (and HTML versions). [issue #1953, PR #2048]
Internally, the documents would use a new way to define cross-linking to
other pages and their chapters, to facilitate different renderers (including
GitHub UI), and file names created for "chunked HTML" documentation format
will no longer have the "chapter number, section number" format which is
not easy to maintain over time with independent builds of documentation
in NUT and the actual and historic snapshots for nut-website for example.
Chapter/Section names will be adapted to produce "chunked HTML" file names
instead. Documentation links rendered in GitHub UI should point to the HTML
pages served by a current iteration of the NUT website. [PR #226, PR #669]
-
A new
configure --enable-spellcheck toggle should add spelling checks
to make check (by default, if tools are available) to facilitate quicker
acceptance of contributions. [#2067]
Published a new maintainer GPG key to sign tags and release artifacts,
and possibly git commits as well, as part of solution for issue #1410.
You can pull it from common OpenPGP servers with the following command:

Bug fixes for fallout possible due to "fightwarn" effort and other
evolution in NUT v2.8.0 release:
-
The
upsdebugx() and similar methods were converted to macros in #685
to avoid useless data manipulations and requests for logged information,
whose results would be ignored instantly because the debug level is
too low. As issue #1455 and PR #1495 found, in two cases the called
commands did "meaningfully" modify data — so without debug logs the
program misbehaved. A known regression for upscode2 driver; might
be or not be a problem with upsd server in NUT v2.8.0 release,
fixed for NUT v2.8.1.
-
A table in
cyberpower-mib (for snmp-ups driver) sources was
arranged in NUT v2.8.0 release in a way that precluded the driver
logic from looking at all of its entries. Also a fix for instant
command definitions had in fact broken them due to other development.
Regressions fixed for NUT v2.8.1 [#1432, #2029]
-
A change for file-change detection in
dummy-ups driver for NUT
v2.8.0 release misfired on some platforms. Regression fixed for NUT
v2.8.1 [#1420]
-
Fixed building of NUT man pages when just a few drivers are selected
by
configure script for custom builds [#1467]
-
Now that
upsdrvctl can pass debugging level through to the launched
driver(s), they would by default stay in the foreground. This can
complicate (or simplify, when intentional) the management of service
instances. Now there are explicit upsdrvctl options for choosing
this (-F/-B), although default behavior is retained. Note that
explicit foregrounding mode also keeps upsdrvctl tool from exiting
and would not wait for one driver to complete initialization before
starting another in case of mass-management loop to start all drivers
(without specifying the single device) [#1759, #1806, #1875]
-
The
apcsmart and apcsmart-old handled invalid data too zealously
and aborted instead of skipping over it, like they did before [#2015]
-
A bit maths optimization in
riello_ser and riello_usb misfired [#2137]
-
Something about compile-time macros or other warnings-related refactoring
seems to have confused the MGE SHUT (Serial HID UPS Transfer) driver
support [#2022]
-
Some warnings were not detected by the tools or build scenarios used
earlier, and only got addressed now
-
An issue was identified which could cause
libupsclient parser of device
and host names to crash upon bad inputs (e.g. poorly resolved environment
variables in scripts). Now it should fail more gracefully [#2052]
-
New
configure --enable-inplace-runtime option should set default values
for --sysconfdir, --with-user and --with-group options to match an
existing NUT deployment — for users who are trying if a custom build
of recent codebase solves their practical issues. For "quick tests", a
shortcut operation ./ci_build.sh inplace was added [#1714]
-
State tree structure and methods (including "dstate" wrapper for common
driver internals) was enhanced with time-stamping of last modification
(setting, changing, deleting the value or some fields in an entry):
this allows to detect stale information in a centralized fashion [#2010]
-
We lacked log information about changes of chroot jail (uncommon) and
of UID/GID (everywhere), which makes troubleshooting harder (e.g. lack
of access to config files or USB device nodes). Now we have it [#1694]
-
A
NUT_DEBUG_PID envvar (presence) support was added to add current
process ID to tags with debug-level identifiers. This may be useful
when many NUT daemons write to the same console or log file. [#2118]
-
huawei-ups2000 is now known to support more devices, noted in docs and
for auto-detection [#1448, #1684]
nutdrv_qx updates:
-
a
battery_voltage_reports_one_pack driver option was added for devices
which "natively" report a battery.voltage for a single battery pack or
cell, not for the whole assembly [#1279]
-
the
voltronic_qs_protocol should now accept both "V" (as before)
and newly "H" dialects, which otherwise seem interchangeable [#1623]
-
the
armac subdriver was enhanced to support devices with a different
response pattern than previously expected per initial contribution.
It was tested to work with Vultech V2000 and Armac PF1 series. [#1978]
nutdrv_qx and blazer updates:
-
extended default ranges for max battery voltage when guessing [#1279]
-
sms_ser, a driver for SMS Brazil UPS Protocol 1Phase, was introduced.
NOTE: it may later become a subdriver under nutdrv_qx. [#2090]
usbhid-ups updates:
-
added support for
subdriver configuration option, to select the
USB HID subdriver for the device manually where automatic match
does not suffice (e.g. new devices for which no vendorid/productid
pair was built into any driver, or for different-capability devices
with same interface chips, notably "phoenixtec/liebert" and "mge") [#1369]
-
cps-hid subdriver now applies same report descriptor fixing logic to
devices with ProductID 0x0601 as done earlier for 0x0501, to get the
correct output voltage data [#1497]
-
apc-hid subdriver now also supports ProductID 0x0004 [#1429]
-
ever-hid subdriver reported a
powerfactor without a namespace (bug
in 2.8.0 release), fixed to outlet.powerfactor
-
the
usbhid-ups driver should now reconnect if libusb returned a
memory allocation error [#1422] (seen as "Can’t retrieve Report 0a:
Resource temporarily unavailable"), which can cause practical problems
in the field — the driver otherwise interpreted the situation as
ups.status being OL OFF and cut the power supply.
-
powercom-hid subdriver: fixed
UPS.Battery.ManufacturerDate to map
to battery.mfr.date (not battery.date which is the maintenance
replacement date) [#1644]
-
added
onlinedischarge_calibration option for UPSes that report
OL+DISCHRG when they are in calibration mode [#2104]
-
powercom driver should now try harder to refresh data from device [#356]
-
tripplite_usb driver now supports configuration of
upsid to match the
specific device (not all firmware/hardware models support this) [#2075]
apcupsd-ups:
-
improvement for
POLL_INTERVAL_MIN from PR #797 was buggy [#2007]
-
fix to clean obsoleted readings (if any) AFTER getting new info from an
apcupsd daemon, to avoid the gap when NUT driver knows nothing [#2007]
apc_modbus driver was introduced, to cover the feature gap between existing
NUT drivers for APC hardware and the actual USB-connected devices (or their
firmwares) released since roughly 2010, which deprecated standard USB HID
support in favor of Modbus-based protocol which is used across the board
(also with their network management cards). The new driver can monitor APC
UPS devices over TCP and Serial connections, as well as USB with a patched
libmodbus (check https://github.com/EchterAgo/libmodbus/commits/rtu_usb
for now, PR pending). [#139, #2063]
-
For a decade until this driver got introduced, people were advised to
use apcupsd project as the actual program which talks to a device, and
NUT apcupsd-ups driver to relay information back and forth. This was a
limited solution due to lack of command and variable setting support,
as well as relaying of just some readings (just whatever apcupsd exposes,
further constrained by what our driver knows to re-translate), with
little leverage for NUT to tap into everything the device has to offer.
There were also issues on some systems due to packaging (e.g. marking
NUT and apcupsd as competing implementations of the same features) which
required clumsy workarounds to get both installed and running. Finally,
there is a small matter of long-term viability of that approach: last
commits to apcupsd sources were in 2017 (with last release 3.14.14 in
May 2016): https://sourceforge.net/p/apcupsd/svn/HEAD/tree/
dummy-ups:
-
Added an
repeater_disable_strict_start option to disable the driver
exiting upon encountering any kind of error at startup (as repeater).
This option should allow for collective upsdrvctl startup despite
individual target UPS to be repeated or upsd not having come up yet.
[#2132]
-
Revised detection of file path (for "dummy" mode) which misfired under
some conditions, and unified several implementations. [#2118]
NUT for Windows:
-
Ability to build NUT for Windows, last tackled with a branch based on
NUT v2.6.5 a decade ago, has been revived with the 2.8.x era codebase [#5].
It is known that at this time some features are not complete, for more
details see https://github.com/orgs/networkupstools/projects/2/views/1
-
Cross-builds of NUT for Windows using Linux and MinGW (and many custom
built dependency packages, as documented in the
scripts/Windows/README.adoc file)
are now regularly tested on NUT CI farm with moderate integration via
custom build script
scripts/Windows/build-mingw-nut.sh [#1489]
-
Semi-native NUT for Windows builds with MSYS2/MinGW x64 environment are
now regularly tested on AppVeyor, with the same
ci_build.sh script and
Makefile checks as used across the board for local developer builds,
Linux/illumos/FreeBSD/OpenBSD/… on dedicated NUT CI farm on Fosshost,
and MacOS on CircleCI [#1552]
snmp-ups updates:
-
Fixed detection for device agents which wrongly return the sysOID value
as a string instead of an OID [#1710]
-
Clearer messages about skipping MIBs during driver initialization [#2037]
-
IETF MIB mapping updated for data points where negative readings
are invalid [#1558]
-
Added SNMP subdriver "apc-epdu-mib" for APC easy PDU support [#1674]
-
Added SNMP subdriver "eaton-pdu-nlogic-mib" for nLogic (rebranded Eaton)
support [#1698]
-
Added SNMP subdriver "hpe-pdu3-cis-mib" for HPE G2 Metered & Switched PDU
initial "unitary" support (no daisychain support yet); also note that due
to SNMP v1 implementation limitations on this device, you should prefer
SNMP v3 to get both read and write rights [#1713]
-
Fixed processing loop for large SNMPv2/SNMPv3 responses where one item
in the middle has a type error [#1682]
-
Better manage the slight nuances (especially in
ups.status) between
Eaton UPSs, and rename mibs from pw to eaton_pw_nm2, and from
pxgx_ups to eaton_pxg_ups [#1715]
-
Fixed the long standing "Warning: excessive poll failures" issue, that
was tied to non-existent OIDs, not well handled in some parts of the
driver [#1716]
-
baytech-mib.c subdriver: fixed baytech_outlet_status_info[] set
of valid outlet status values [#1871]
-
cyberpower-mib.c subdriver: support devices which report the shorter
Vendor OID as their sysOID, e.g. "CyberPower PowerPanel Personal" [#1997]
and support more data points including hardware status alarms [#1982]
-
The
bestfortress driver shutdown handling was fixed to use a non-trivial
default timeout [#1820]
-
The
optiups driver only gave accurate voltage information with 120VAC
models and assumed a 12V battery when calculating capacity. There is
a protocol command that gives a (fixed) voltage which correlates with
the voltage selection DIP switches on the back of the UPS, taking into
account whether it is a 120 or 240VAC model. Likewise, now the battery
capacity fix is applied globally, based on whether or not the battery
voltage is greater than 20V. [#2089]
GPIO drivers [#1855]:
-
Added a new category of drivers, using GPIO interface to locally connected
devices (currently limited to 2018+ Linux libgpiod, but its architecture
was designed to support more OSes with their equivalents - PRs welcome)
-
generic_gpio_libgpiod driver using libgpiod backend was added
(defaults to be required on Linux, optional on other platforms)
-
Added support for
make install of PyNUT module and NUT-Monitor desktop
application [#1462, #1504]
-
Regular CI coverage for NUT codebase enhanced with CircleCI running some
scenarios on MacOS, might add Windows in the future. Fixed some build
issues for MacOS that had crept into NUT v2.8.0 release [#1415, #1421]
-
NUT software-only drivers (dummy-ups, clone, clone-outlet) separated from
serial drivers in respective Makefile and configure script options [#1446]
-
Fixed support for common USB matching options ("vendor", "device", "bus",
etc.) for
riello_usb and richcomm_usb [#1763] and updated man pages
of all USB drivers using these options to include the same description
[#1766]
-
Added a "busport" USB matching option (if supported by the hardware, OS and
libusb on the particular deployment, it should allow to specify physical
port numbers on an USB hub, rather than logical "device" enumeration values,
and in turn — this should be less volatile across reboots etc.) [#2043]
-
Added an
allow_duplicates flag for common USB matching options which
may help monitor several related no-name devices (although without knowing
reliably which one is which… better than nothing) [#1756]
-
The
nut-scanner program should now suggest same configuration fields as
those used by common USB matching options in (most of the) drivers, e.g.
adding "device" to the generated configuration section [#1790]
-
Stuck drivers that do not react to
SIGTERM quickly are now retried with
SIGKILL [#1424]
-
Each driver should now report its
driver.state to help readers determine
whether it is initializing, reconnecting, or running regular loops [#1767]
-
Code which resolves full paths to libraries should now consider the common
environment variable
LD_LIBRARY_PATH as a preferred possible override
to built-in paths (note that most operating systems advise against setting
this variable unless troubleshooting, although other systems rely on it)
[#805]
-
Debug information tracing methods like
upsdebugx() should now be less
limited in the sizes of messages that they can print, such as path names
that may be quite long. Note that the OS methods manipulating the strings,
and receivers such as logging systems, may still impose limits of their own.
-
The
nut-scanner usage and debug printouts now include the loadable library
search paths, to help troubleshooting especially in multi-platform builds;
pre-filtering of the built-in paths was introduced (to walk only existing
and unique directory names) [#317]
-
The nut-scanner program was updated to fall back to loading unresolved
library filenames, hoping that
lt_dlopen() implementation on the current
platform would find library files better [#805]
-
Detection of
libltdl in configure script updated with fallback code to
find it on systems that deliver the library to /usr/local/lib (e.g. on
FreeBSD) [#1577]
-
An explicit
configure --with-nut-scanner toggle was added, specifically
so that build environments requesting --with-all but lack libltdl would
abort and require either to install the dependency or explicitly forfeit
the tool (some distro packages missed it quietly in the past) [#1560]
-
The
nut-scanner program should now by default warn about serial numbers
which do not make much sense (are duplicate, empty, all same character, etc)
[#1810]
-
Existing openssl-1.1.0 support added for NUT v2.8.0 release was tested to
be sufficient without deprecation warnings for builds against openssl-3.0.x
(but no real-time testing was done yet) [#1547]
-
upslog: Added support for logging multiple devices with one call to the
program [#1604]
-
Documentation to integrate NUT USB driver startup with
usb_resetter script
has been contributed to scripts/usb_resetter (the script itself is tracked
externally on GitHub), along with a configuration example for Linux+systemd
[#1887]
-
Some fixes applied to Solaris/illumos packaging and SMF service support
[#1554, #1564]
Some fixes for builds on older OSes with less functional default system
shell interpreters - now autogen.sh supports a CONFIG_SHELL envvar
to inject its value into generated configure script [#1736]
-
Note that you may have to install additional tools (possibly from
third-party FOSS packaging efforts) to prepare and build the NUT
codebase, and/or prefer non-default system provided implementations
(e.g. to use the XPG4
grep with -E support on Solaris as detailed
in https://github.com/networkupstools/nut/issues/1736 comments)
-
Build environment configuration notes in docs/config-prereqs.txt
file refreshed to cover building of current NUT codebase in CentOS 6
[#1804] and Solaris 8 [#1736, #1738]
-
configure script, reference init-script and packaging templates updated
to eradicate @PIDPATH@/nut ambiguity in favor of @ALTPIDPATH@ for the
unprivileged processes vs. @PIDPATH@ for those running as root [#1719]
-
configure script enhanced: --with-unmapped-data-points option allows
to build SNMP and USB-HID subdrivers with entries discovered by the scripts
which generated them from data walks, but developers did not rename yet
to NUT mappings conforming to docs/nut-names.txt standards [#1699]
PyNUT.py version bumped to 1.5.0 with some improvements:
-
ListClients() method fixed (was broken in many ways), and is now
CI-tested [#549]
-
DeviceLogin() method added (mostly as aid to CI-test ListClients()
in a practically relevant manner, so far)
nutclient C++ library:
-
added
listDeviceClients() and deviceGetClients(dev) to Client
classes, and Device::getClients() to match PyNUT capabilities [#549]
upsclient C library:
-
added support for
NUT_QUIET_INIT_SSL environment variable to hide
the infamous "Init SSL without certificate database" warning [#1662]
-
The
upsd.conf listing of LISTEN addresses was previously inverted
(the last listed address was applied first), which was counter-intuitive
and fixed for this release [#2012]
-
The
upsd configured to listen on IPv6 addresses should handle only
IPv6 (and not IPv4-mappings) to avoid surprises and insecurity; it
will now warn if a host name resolves to several addresses (and will only
listen on the first hit, as before in such cases) [#2012]
-
A definitive behavior for
LISTEN * directives became specified, to try
handling both IPv4 and IPv6 "any" address (subject to upsd CLI options
to only choose one, and to OS abilities). When both address families are
enabled, the upsd data server will first try to open an IPv6 socket
asking for disabled IPv4-mapped IPv6 address support (if the OS honors
that), and then an IPv4 socket (which may fail if the IPv6 socket already
covers it anyway); in other words, you can end up with one or two separate
listening sockets. [#2012]
-
sstate (server state, e.g. upsd) should now "PING" drivers also if they
last reported themselves as "stale" (and might later crash) so their
connections would be terminated if really no longer active [#1626]
-
Clarified documentation in codebase according to end-user feedback [#1721,
#1750 and others over time]
upsmon client changes include:
-
Several fixes for
upsmon behavior [#1761, #1680…], including new
ability to configure default POWERDOWNFLAG location — packagers are
encouraged to pick optimal location for their distributions (which
remains mounted at least read-only late in shutdown) and a new optional
POLLFAIL_LOG_THROTTLE_MAX setting [#529, #506]
-
Also
upsmon should now recognize OFF and BYPASS flags in ups.status
and report that these states begin or end. The OFF state usually means
than an administrative action happened to power off the load, but the UPS
device is still alive and communicating (USB, SNMP, etc.); corresponding
MONITOR'ed amount of power sources are considered not being "fed" for
the power value calculation purposes. The BYPASS state is now treated
similarly to ONBATT: currently this UPS "feeds" its load, but if later
communications fail, it is considered dead. This may have unintended
consequences for devices (or NUT drivers) that do not report these modes
correctly (e.g. an APC calibration routine seems to start with a few
seconds of "OFF" state), so the reported status is only considered as a
loss of feed if it persists for more than OFFDURATION seconds. [#2044,
#2104]
-
Introduced
SHUTDOWNEXIT no configuration toggle for systems which
require a long time to stop their workload such as virtual machines.
Since the disconnection of a "secondary" client is treated by the
"primary" system as permission to proceed with its own shutdown and
power-off for the UPS, the original (now merely default) behavior to
call SHUTDOWNCMD and immediately exit could be counter-productive.
An optional delay can also be introduced. [#2133]
-
Note there were other changes detailed below which impacted several NUT
programs, including
upsmon.
Extended Linux systemd support with optional notifications about daemon
state (READY, RELOADING, STOPPING) and watchdog keep-alive messages [#1590]
-
Normally inability to send such notifications (e.g. lack of systemd
or similar framework on the particular platform) would be reported once
per daemon uptime on its console log, to help troubleshooting situations
where such lack of notifications can cause automated service restarts.
These messages can be hidden by setting
NUT_QUIET_INIT_UPSNOTIFY=true
environment variable in init-scripts on platforms where such frameworks
are not expected. [#2136]
-
Extended Linux systemd units with aliases named after the daemons:
nut-server.service as upsd.service, and nut-monitor.service as
upsmon.service (so simple systemctl reload upsd can work) [#1777]
-
Extended driver-server socket protocol with
BROADCAST (num) keyword,
and a NOBROADCAST as a shortcut for BROADCAST 0. This allows clients
to toggle whether they want to receive send_to_all() updates from a
driver, or only answers to requests they send [#1914]
-
Added support for
make sockdebug for easier developer access to the tool;
also if configure --with-dev is in effect, it would now be installed to
the configured libexec location. A man page was also added. [#1936]
Numerous daemons (upsd, upsmon, drivers, upsdrvctl, upssched)
which accepted -D option for debug setting previously, now can also
honour a NUT_DEBUG_LEVEL=NUM environment variable if no -D arguments
were provided. Unlike those arguments, the environment variable does
not enforce that daemons run in foreground mode by default [#1915]
-
Note that unlike some other NUT daemons,
upssched with enabled
debug does not stop reporting on stderr! [#1965]
-
A bug in
upssched was discovered and fixed, where it ran a tight loop
stressing the CPU; it was presumably introduced between NUT v2.7.4 and
v2.8.0 releases [#1964, #1965]
-
Implemented generic support for INSTCMD and SETVAR use-cases shared by
all drivers, and in particular to see and change active debug verbosity
using the driver-server and server-client protocol (at higher priority
than CLI or config file choices) per [#1285], e.g.
# Set verbosity level 6:
:; upsrw -s driver.debug=6 UPS
# Set verbosity level 0 to disable the noise (even if debug_min is set):
:; upsrw -s driver.debug=0 UPS1@localhost
# Un-set the protocol override, honour CLI or config-file settings again:
:; upsrw -s driver.debug=-1 remoteUPS@1.2.3.4
+
and a driver.killpower instant command (for safety, must be unlocked by
driver.flag.allow_killpower protocol setting or allow_killpower
configuration flag), which is now the first choice for driver -k
operations [#1917, #1923]
-
Implemented basic support for
ups.conf reloading in NUT drivers,
with a driver.reload-with-error instant command (more commands and
signal handling may be available depending on platform), with a goal
of changing inconsequential settings like debug_min for a running
driver. This can also benefit the drivers on systems managed by real-time
nut-driver-enumerator and for simpler changes the drivers get only
reloaded and not redefined and restarted. Reload signals should also
be reasonably supported with upsdrvctl tool. Relevant CLI options
for -c CMD handing were added to drivers and upsdrvctl, although
their availability may vary between operating systems [#1903, #1914, #1924]
-
Drivers should now accept
SIGURG (or SIGWINCH on systems that lack
the former) on POSIX platforms to dump their current state information
and move on. Such report goes to stdout of the driver process (may
be disconnected when background mode is used) — this can help with
troubleshooting [#1907]
-
Recipes and
main.c code were enhanced to produce a libdummy_mockdrv.la
helper library during build (not intended to be installed nor distributed),
in order to facilitate creation of test programs which behave like a driver
[#1855]
-
Further revision of public headers delivered by NUT was done, particularly
to address lack of common data types (
size_t, ssize_t, uint16_t,
time_t etc.) in third-party client code that earlier sufficed to only
include NUT headers. Sort of regression by NUT 2.8.0 (note those consumers
still have to re-declare some numeric variable types used) [#1638, #1615]
-
The
COPYING file was updated with licenses and attribution for certain
source code files and blocks coming from the Internet originally [#1758]
-
The
tools/gitlog2changelog.py.in script was revised, in particular to
generate the ChangeLog file more consistently with different versions
of Python interpreter, and without breaking the long file paths in the
resulting mark-up text [#1945, #1955]
-
The "NUT client for VMware ESXi" project (by René Garcia) got its build
recipes published on GitHub at https://github.com/rgc2000/NutClient-ESXi
[#1961]
2.2. Release notes for NUT 2.8.0 - what’s new since 2.7.4
Note
Earlier discussions (mailing list threads, GitHub issues, etc.) could
refer to this change set (too long in the making) as NUT 2.7.5.
-
New (optional) keywords for configuration files were added,
so existing NUT 2.7.x builds would not accept them if some
deployments switch versions back and forth — due to this,
semantically the version was bumped to NUT 2.8.x.
-
Add support for openssl-1.1.0 (Arjen de Korte)
-
libusb-1.0 API support in addition to libusb-0.1 API [#300]
-
Add support for
DISABLE_WEAK_SSL=true in upsd.conf to disable older/weaker
SSL/TLS protocols and ciphers: when NUT is built against relatively recent
versions of OpenSSL or NSS it will be restricted to TLSv1.2 or better.
For least-surprise, currently defaults to false and complains in log
[PR #1043]
-
Add support for
ALLOW_NO_DEVICE=true (as an upsd.conf flag or environment
variable passed from caller of the program), to allow starting the data
server initially without any device configurations and reloading it later
to apply config changes on the fly [PR #766]
-
Add support for
debug_min=NUM setting (ups.conf, upsd.conf, upsmon.conf)
to specify the minimum debug verbosity for daemons. This allows "in-vivo"
troubleshooting of service daemons without editing init scripts or service
unit definitions.
-
Improve support for upsdrvctl for managing of numerous device configs,
including default "maxretry=3" and a "nowait" option to complete the
"start of everything" mode after triggering the drivers and not waiting
for them to complete initializing. This matters on systems that monitor
from dozens to hundreds of devices.
-
Drivers support a new value for
synchronous setting, which is the
new default now: auto. Initially after driver start-up this mode
acts as the older default off, but would fall back to on in case
the driver fails to send reports to upsd by overflowing the socket
buffer in async mode — so the next connections of this driver uptime
would be synchronized (potentially slower, but safer — blocking on
writes to the data server). This adaptation would primarily impact
and benefit devices with many (hundreds of) data points, such as
ePDUs and daisy chains. [issue #1309, PR #1315]
-
Daemons such as upsd, upsmon, upslog, and device drivers previously
implied that enabled debugging (or upslog to stdout) means foreground
running, otherwise the daemon was always sent to the background.
Now there are explicit options for this (
-F/-B), although default
behavior is retained. This change is used for simplified service unit
definitions.
Improvements for device discovery or driver "lock-picking", including
general support for:
-
"Standalone" mode (
-s option), to monitor a device which is not
detailed or mentioned in ups.conf
-
NUT_ALTPIDPATH and NUT_STATEPATH environment variables to override
the paths built into the driver binary [PR #473 and #507]
-
"Driver data dump" mode (
-d option), to poll a device for one or
few (update_count ) loops, report discovered values (dump the data
tree in upsc-like format), and exit. This complements the nut-scanner
for finding and identifying devices.
support for new devices:
-
IBM 6000 VA LCD 4U Rack UPS; 5396-1Kx (USB)
-
Phoenix Contact QUINT-UPS model 2320461 (Modbus)
-
Tripp-Lite SU3000LCD2UHV (USB; protocol 1330)
-
Emerson Avocent PM3000 PDU (SNMP)
-
HPE ePDU (SNMP)
-
nutdrv_qx: enhanced estimation of remaining battery runtime based
on speed of voltage drop, which varies as they age [PR #1027]
nutdrv_qx: several subdrivers added or improved, including:
-
"snr" subdriver with USB connection, for SNR-UPS-LID-XXXX [PR #1008].
Note that end-users should reference explicitly the
snr subdriver
in their ups.conf settings because of USB chip using the same
values of VendorID/ProductID as fabula_subdriver, fuji_subdriver,
and krauler_subdriver.
-
"hunnox" subdriver, as a dialect of earlier "fabula" [PR #638]
adds support for Hunnox HNX-850 with USB connection and reported to work
for Powercool, Iron Guardian, ARES devices and possibly many others from
discussions linking to the pull request which introduced the driver.
-
"phoenixtec" subdriver for Masterguard A and E series, device series
A700/1000/2000/3000(-19) and E40/60/100(-19). [PR #975]
-
"ablerex" subdriver provided by the OEM vendor, note that it replaces
"krauler_subdriver" as default handler for VID:PID 0xffff:0x0000
[PR #1135]
-
Legrand HID defined and handled by "krauler_subdriver" by default
[PR #1075, issue #616]
-
add new "armac" subdriver, tested with Armac R/2000I/PSW, but should
support other UPSes that work with "PowerManagerII" software from
Richcomm Technologies from around 2004-2005 [PR #1239, issue #1238]
-
microsol-apc (starting at version 0.68 as derived from solis 0.67):
adding support for newer APC Back-UPS BR hardware, such as
APC Back-UPS BZ1500, BZ2200BI and BZ2200I [PR #994]
-

and possibly some related FSP UPS models. [PR #954]
-
socomec_jbus: added new driver for modbus-based JBUS protocol over serial
RS-232 for Socomec UPS (tested with a DIGYS 3/3 15kVA model, working
on Linux x86-64 and Raspberry Pi 3 ARM). [PR #1313]
-

The driver has been tested against PULS UPS (model UB40.241) via
MOXA ioLogikR1212 (RS485) and ioLogikE1212 (TCP/IP), and configuration
allows to map custom registers and addresses to NUT events [PR #1052]
-
genericups: added support for FTTx battery backup devices, and new signal
type mappings for the contact closure pins interpretation (RB for replace
battery, BYPASS for disconnected battery, and "none" or NULL for signals
to ignore) [PR #1061]

NUT-Monitor name is retained for wrapper
script which calls one of these, such that the current system can execute
[PRs #1310, #1354]
-
Various USB driver families: expanded device-matching with "device" in
addition to "bus" and generic USB fields. This is needed to support
multiple attached devices that seem identical by other fields (e.g.
same vendor, same model, same USB bus, and no serial number) [PR #974]
-
Various USB driver families: Improved HID parsing for byte-stream to
number conversions on different CPU architectures [PR #1024]
-
Various USB HID driver families: added support for composite devices
utilizing interface greater than 0 for the UPS interface [PR #1044]
usbhid-ups:
-
added generic framework for fixing Report Descriptors which can be

Solaris/illumos SMF to inspect current NUT configuration in ups.conf
file and generate service management instances for each currently
tracked power device. Also introduced services to monitor the NUT
configuration and react to editions of this file, mostly intended
for deployments that do massive monitoring of dynamically changing
farms of power devices.
-
Fix File descriptors leaks by upsmon and upssched (SELinux errors)

-
upsrw: display the variable type beside ENUM / RANGE
-
Added
PROTVER as alias to NETVER to report the protocol version in use.
Note that NUT codebase itself does not use this value and handles commands
and reported errors individually [issue #1347]
-
Implement status tracking for instant commands (instcmd) and variables
settings (setvar): this allows to get the actual execution status from the
driver, and is available in libraries and upscmd / upsrw [PR #659]
-
Add support for extra parameter for instant commands, both in library and
in upscmd
-
dummy-ups can now specify
mode as a driver argument, and separates the
notion of dummy-once (new default for *.dev files that do not change)
vs. dummy-loop (legacy default for *.seq and others) [issue #1385]
new protocol variables:
Master/Slave terminology was deprecated in favor of Primary/Secondary
modes of upsmon client:
-
Respective keywords in the configuration files (
upsd.users and
upsmon.conf) are supported as backwards-compatible settings,
but the obsoleted values are no longer documented.
-
Protocol keyword support was similarly updated, with
upsmon now
first trying to elevate privileges with PRIMARY <ups> request,
and falling back to MASTER <ups> just in case it talks to an
older build of an upsd server.
-
For the principle of least surprise, NUT codebase still exposes the
net_master() (as handler for MASTER net command) in header and
C code for the sake of existing linked binaries, and returns the
OK MASTER-GRANTED line to the older client that invoked it.
-
Newly introduced
net_primary() (as handler for PRIMARY net command)
calls the exact same application logic, but returns OK PRIMARY-GRANTED
line to the client.
-
Python binding updated to handle both cases, as the only found in-tree
protocol consumer of the full-line text.
-
For more details see issue #840 and several pull requests referenced
from it, and discussions on NUT mailing lists.
Build fixes:
-
In general, numerous fixes were applied to ensure portability and avoid
warnings (fixing a number of real bugs that caused them); CI was extended
to keep the codebase free of those types of warnings which we have got
rid of, requiring builds to succeed cleanly in several dozen combinations
of compiler versions, C standard revisions (C99 upwards, though on many
OSes with GNU99+ extensions), operating systems and CPU architectures.
-
Public CI introduced to automatically test every contribution (PR) and
resulting increment of main NUT codebase, including Travis CI and LGTM.com
services, and a Jenkins farm on virtual hardware donated by Fosshost.org;
this augments testing earlier provided for some branches by Buildbot.
-
Added cppunit testing with valgrind for the C++ client library
-
Make targets added for shell script syntax checks for helper and service
scripts
-
Make targets added for spellcheck and for maintenance of the dictionary,
including incremental spellcheck to only parse recently edited text files
-
The AsciiDoc detection has been reworked to allow NUT to be built from
source without requiring asciidoc/a2x (using pre-built man pages from
the distribution tarball, for instance)
-
Makefile contents rearranged for more resilient out-of-tree and in-tree
builds beside those made from the root workspace directory
-
Makefiles are tested with GNU Make and BSD Make to ensure portable recipes
-
More use of
pkg-config to detect dependencies at configure time, as
well as fail-safe detection of presence of pkg-config (and its macros)
to survive and build without it too
-
"slibtool" pedantic nuances now supported, allowing an alternative to
GNU libtool
-
Build scripts updated to remove obsoleted calls to cleanly work with
autoconf-2.70 releases in 2020 (also works with 2.69 which was the
earlier release since 2012)
-
Dynamic library loading used in certain programs and use-cases improved,
especially for 64-bit vs 32-bit builds on multiple-bitness OSes
-
Logging routines like
upsdebugx() were refactored as macros so there
is slightly less overhead when logging is disabled [PRs #685 and #1100]
-
Numerous classes of compilation warnings eradicated, many of those being
potential issues with implicit data type conversions and varied numeric
type width, signedness, string buffer size, uninitialized variables or
structure fields; some more in progress
-
Several logical errors found and fixed during this walk over codebase.
-
Cases where compilers were overly zealous and particular code was written
the way wit was intentionally, including some comparisons that help with
different-bitness builds but indeed seem superfluous in a certain single
bitness, were commented and encased in pragmas to disable the warnings
-
Basic coding style (indentations, lack of trailing white space) applied
per developer guide, but not automatically enforced/checked yet.
-
Due to changes needed to resolve build warnings, mostly about mismatching
data types for some variables, some structure definitions and API signatures
of several routines had to be changed for argument types, return types,
or both. Primarily this change concerns internal implementation details
(may impact update of NUT forks with custom drivers using those), but a
few changes also happened in header files installed for builds configured
--with-dev and so may impact upsclient and nutclient (C++) consumers.
At the very least, binaries for those consumers should be rebuilt to remain
stable with NUT 2.8.0 and not mismatch int-type sizes and other arguments.
-
As usual, more bugfixes, cleanup and improvements, on both source code
and documentation.

2.6. Release notes for NUT 2.7.1 - what’s new since 2.6.5
Note
There was no public NUT 2.7.0 release.
-
This release is an interim release, part of the testing series, and the
first release after the transition from Subversion to Git.
The last release (2.6.5) is almost a year old. A lot of work has
been done, but a good amount remains to achieve 2.8.0 goals.
Please read the UPGRADING.adoc notes.
-
Added support for SSL via the Mozilla NSS library, in addition to the
existing OpenSSL support.
-
Added a new driver, nutdrv_qx, for Megatec/Qx devices. This driver will
eventually replace the blazer_ser and blazer_usb drivers. In particular, it
adds support for Voltronic Power devices.
-
Increased USB_TIMEOUT to standards-compliant 5.000 seconds in most drivers.
This should reduce the number of timeouts on low-speed USB 1.1 devices.
-
The jNut Java source has been split into a separate GitHub repository.
-
Added many devices to the HCL. Of particular note are many Tripp Lite USB
HID PDC models which were tested against NUT by Tripp Lite.

is also available (docs/nut.dict), providing a glossary of
terms related to power devices and management
-
Improve systemd integration
-
snmp-ups: Fixed a crash on outlet management, and added delta_ups MIB
support. Also fixed mappings for upsBypassVoltage, upsBypassCurrent, and
upsBypassPower in three-phase IETF MIB.
2.7. Release notes for NUT 2.6.5 - what’s new since 2.6.4
2.8. Release notes for NUT 2.6.4 - what’s new since 2.6.3
-
This release fixes an important vulnerability in upsd
(CVE-2012-2944: upsd can be remotely crashed)
NUT server (upsd), from versions 2.4.0 to 2.6.3, are exposed to
crashes when receiving random data from the network.
This issue is related to the way NUT parses characters,
especially from the network. Non printable characters were missed
from strings operation (such as strlen), but still copied to the
buffer, causing an overflow.
Thus, fix NUT parser, to only allow the subset of ASCII charset from
Space to ~
(Reported by Sebastian Pohle, Alioth bug #313636, CVE-2012-2944)
A separate patch, which applies to any faulty version, is also available:
http://trac.networkupstools.org/projects/nut/changeset/3633
For more information, refer to the Common Vulnerabilities and Exposures:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2944
-

2.10. Release notes for NUT 2.6.2 - what’s new since 2.6.1
-
NUT can now monitor power supply units (PSU) in servers, through IPMI, using
the new experimental nut-ipmipsu driver. Users are encouraged to test it,
and send feedback and debug output to the development mailing list.
This requires GNU FreeIPMI (0.8.5 or higher) development package or files.
Thanks goes to Al Chu, FreeIPMI project leader, for his help during this
development.
NUT now provides a tool, called nut-scanner, to discover supported devices,
both local and remote. nut-scanner will help to ease the configuration step,
and power infrastructure discovery.
This development, sponsored by Eaton, supports the following methods:
-
USB,
-
SNMP,
-
XML/HTTP (from Eaton),
-
NUT servers, using the classic connect or Avahi / mDNS methods.
IPMI support will be added in the next release.
A separate library, called libnutscan, is also available to provide these
feature. Future NUT releases will provides binding for the supported
languages (Perl, Python and Java).
-
NUT now provides a Java interface called jNut.
This development, sponsored by Eaton, is currently limited to the client
interface. But it will be broaden to device discovery and configuration in
the future.
For more info, refer to nut/scripts/java/README, or the developer guide
(chapter Creating new client). Javadoc documentation is also provided,
along with Java archives (.jar) in the Download section.

with battery.runtime.low and end of battery life (life cycle monitoring)
support; new measurements for 5 PX are also supported now (outlet power
factor, power, real power and current).
-
apcsmart has been updated to support more variables and features; the
previous driver is however still available as apcsmart-old, in case of
issues.
-
bcmxcp now supports per outlet startup and shutdown delays setting; shutdown
delay is also used, when available, for outlet.n.shutdown.return instead of
the default 3 seconds.
-
snmp-ups.c has a new initialization method, that uses sysObjectID, which is
a pointer to the preferred MIB of the device, to detect supported devices.
This speeds up even more init stage and should render void the use of mib
option. SNMP v3 session initialization has also been fixed, and Eaton PDU
support has been completed.
-
Initial support has been added for systemd, the System and Service Manager
from RedHat.

2.24. Release notes for NUT 2.0.1 - what’s new since 2.0.0
2.25. Release notes for NUT 2.0.0 - what’s new since 1.4.x
-
The new naming scheme for variables and commands (introduced in 1.4)
is now mandatory. The 1.4 tree supported both the old (STATUS) and
the new (ups.status) as a transitional release, and now that time is
over.
This means that 2.0 is generally smaller than 1.4 code, since the
interim compatibility hacks have been removed.
-
New serial handling code has been added, with greatly simplified
operations. The old mess involving repeated calls to sigaction,
alarm, and read has been condensed to a select-read loop.
This change allows drivers which don’t do any serial communications
at all (hidups, snmp-ups) to drop that baggage, so they are a bit
smaller when compiled.
-
The drivers now recognize "chroot=' and user= in the global section
of ups.conf. This means you don’t have to use -r and -u when
starting upsdrvctl.
-
upsmon now supports the -K argument to check for the presence of the
POWERDOWNFLAG file. If it exists and contains the magic string, then
upsmon will exit(EXIT_SUCCESS). Otherwise, it will
exit(EXIT_FAILURE).
This feature can be used to simplify shutdown scripts, since now you
don’t have to keep the script in sync with the upsmon.conf.
-
Many small things like signed value comparisons, int vs. size_t and
proper use of const/struct were fixed throughout the source. These
were mostly for correctness, but a few potential bugs involving very
big or very small numbers were fixed at the same time.
-
The access control system in upsd.conf has been reworked and
simplified. Since access levels have become meaningless in recent
releases, the new system is just ACCEPT <acl> or REJECT <acl>.
If you are upgrading from a previous version of the software, you
will have to edit your upsd.conf to use this method. See
the UPGRADING.adoc file for more details.
-
The build process now halts when make fails in one of the
subdirectories.
[Petter Reinholdtsen, Charles Lepple]
-
Helper data for using upsclient via pkgconfig is now created if
pkgconfig is detected when configure runs.
[Arnaud Quette]
-
The polling interval in drivers may now be set with pollinterval
in ups.conf.
[Gabriel Faber]
-
Blazer UPS equipment is now supported with the blazer driver.
[Phil Hutton]
-
Energizer USB UPS hardware is now supported on Linux with a new
experimental driver.
[Viktor T. Toth]
-
The newhidups driver has been merged as the first step towards
portable USB UPS support. This will eventually replace the old
Linux-only hidups driver. The newhidups driver is tagged
experimental since it is under active development.
[Arnaud Quette, Charles Lepple]
-
The newapc driver has been renamed to apcsmart, replacing the old
driver with that name. If you used the newapc driver, be sure to
delete the old binary and fix your ups.conf.
-
The apcsmart driver now supports asynchronous notification data
from the hardware, which means it can wake up as soon as something
happens. This affects the OL/OB/LB/RB data in ups.status, and
generally reduces the latency in dispatching status changes by a few
seconds.
-
The apcsmart driver can now support quirky hardware which does not
provide the usual listing of valid command characters. This feature
is necessary to monitor new models like the APC CS 350 and old ones
like the Matrix 5000. It also now has sdtype=4 to handle the strange
shutdown behavior on the CS series.
-
The belkin driver now works around broken firmware version 001,
avoiding a lengthy delay at startup. It also implements the shutdown
sequence differently, and should actually work on more hardware now.
-
The bestups driver has been slowed down to play nicer with the
hardware, and is much more reliable as a result. Among other things,
it should always detect the UPS on the first try, meaning no more
"dot dot dot" when it starts.
-
The cyberpower driver is no longer tagged experimental, and now
supports powering off the load. It also supports battery tests via
instcmds.
-
Effekta MT 2000 RM hardware is now supported by the fentonups driver.
[Christoph Moar]
-
The new safenet driver supports UPS hardware that uses the protocol
of the same name. This includes models from many manufacturers,
including Fairstone, Fenton, Gemini, Powerwell, Repotec, Soltec and
Sweex. See the README or driver.list for the full details.
[Arjen de Korte]
-
The genericups driver now has type 20 to monitor the Powerware 5119
RM. See http://lists.exploits.org/ups/Oct2003/00052.html.
[Daniel Thompson]
-
The belkinunv driver has been added to allow monitoring Belkin
Universal UPS hardware.
[Peter Selinger]
-
Cyber Power Systems 1100AVR hardware which has a different protocol
than the existing binary type (supported by cyberpower) is now
supported by the experimental cyberpower1100 driver.
[Walt Holman]
-
upsdrvctl now returns success or failure information in the exit
code. Any failure during a requested operation will result in a
nonzero value (specifically EXIT_FAILURE).
2.26. Release notes for NUT 1.4.0 - what’s new since 1.2.x
-
The drivers and upsd now communicate over Unix domain sockets instead
of state files, shared memory, or state files with mmap. This change
makes many things possible, including the new dynamic variable and
command naming scheme described below.
There is a new development tool called sockdebug in the server
directory for debugging driver-server communications on the sockets.
-
The old static variable scheme has been replaced by a new dynamic
implementation. Vague names have been turned into meaningful names
that fit into an organized system. UTILITY is now input.voltage.
OUTVOLT is now output.voltage.
This also applies to the names of instant commands. BTEST1 is
test.battery.start, and BTEST0 is test.battery.stop.
The old names are still supported for compatibility with older
clients. This compatibility mode will be maintained throughout
the 1.4 series, and will be gone by the release of 2.0. Users
with older clients are encouraged to upgrade their software
during this time.
-
The network protocol has been expanded to handle these new names.
Older functions which only apply to the old names will continue to
be supported through the 1.4 series.
-
The drivers and server (upsd) can now change their user ids and
chroot themselves with the new -u and -r arguments. This lets you
create a "chroot jail" with the bare minimum components.
This technique is used to provide a higher degree of security. If
someone exploited upsd to get a shell somehow, they would be stuck
in the jail.
-
upssched now explicitly confirms reception of timer commands before
exiting. This was done to avoid a race where one process would
exit right when another one was starting. The second one would
believe its command had been handled when it had been lost.
-
upslog has been reworked to use standard getopt parsing to provide
the monitoring settings. The old way of specifying arguments is
still supported for backwards compatibility.
upslog has also been changed to only parse the format string once,
rather than doing it every time through the loop. This should
provide a minuscule drop in CPU utilization.
-
Usernames are now required in upsmon and upsd. This means that you
must add a username to your MONITOR lines in upsmon.conf and then
create a matching user in upsd.users.
Installations from the 1.2 era probably already used usernames, so
this mostly affects those from 1.0 and before.
-
Drivers are now pinged regularly by upsd when they aren’t posting
updates about the UPS status. This provides another check in the
data validation process. If upsd fails to get a response within
a few seconds, the UPS will be marked stale.
-
A few minor memory leaks were discovered with valgrind and squashed.
-
upsstats now reuses connections to upsd when cycling through multiple
entries in the hosts.conf. This makes things a bit faster and
avoids some of the noise in the syslog.
This only applies to entries that are adjacent. To take advantage
of this feature, you may have to rearrange them per example below.
Connection reuse for nonadjacent entries may be considered in the
future.
MONITOR ups-1@host-1 ...
MONITOR ups-1@host-2 ...
MONITOR ups-2@host-2 ...
MONITOR ups-3@host-3 ...-
upsd now warns about insecure configuration files at startup.
These files (upsd.conf, upsd.users, and the certfile) should
only be readable by upsd. Never make them world-readable.
-
The programs no longer print "shutting down" when they are just
exiting. This was changed to avoid confusion about the term, since
"shutting down" has a special meaning in UPS software.
-
Signal handlers no longer do any significant amount of work. Some of
the programs used to do numerous things in there, raising concerns
about reentrancy. They now set flags and allow the main loop to do
the actual work from there.
-
A bug in upsmon where NOTIFYFLAG settings could be ignored was fixed.
-
Group handling has been changed. configure no longer accepts
--with-group, and the programs no longer setgid() to a hardcoded
value. They now setgid() to the primary group of whatever the
user value may be.
This may be compiled in with --with-user as before, and many programs
accept -u to override it at runtime.
-
The state path is no longer created during make install. Users
are now expected to create it themselves. This removes a lot of
evil complexity from the build and install sequences.
-
upsd no longer implements the DROP access command, as it
could confuse the clients by getting them out of sync. DROP is now
implemented as DENY, which sends an error message. If you use DROP,
you should change it to DENY rather than relying on this
compatibility measure.
-
The belkin driver no longer reports OFF and OL at the same time.
-
The bestups driver no longer sleeps during polls, which makes it
more responsive to things like instant commands.
-
The cyberpower driver now has much better hardware detection code
and no longer freezes at startup under some conditions. It also now
supports the shutdown function. Instant commands for shutdowns and
battery tests were also added.
-
The dummyups testing driver has been removed. The dummycons testing
driver can do everything that dummyups once did and much more.
dummycons is also now built by default for easier testing.
-
The newapc driver has been reworked to take advantage of the new
internal driver state functions. Some variables without an obvious
purpose were dropped.
-
The newapc driver now sends all five bytes when using sdtype 1.
Previously it didn’t send the entire string, and it didn’t work.
[Don Lewis]
-
The hidups driver has been expanded to allow for setting variables,
a shutdown sequence, and more.
[Arnaud Quette]
-
The mge-utalk driver had trouble establishing communications in
some cases due to the RTS line being set. This has been fixed.
The mge-shut driver has been added to the tree, and has replaced
the older mge-ellipse driver.
[Arnaud Quette, Philippe Marzouk]
-
Outlet-level control has been defined in the variable tree, and will
be added to drivers where the hardware supports it. This can be
used to shut down some components earlier than others to prolong
your runtime on battery.
This is supported in the mge-shut driver now, and may show up in
others before long.
[Arnaud Quette]
-
KIN-2200AP hardware is now recognized by the powercom driver.
This change may also support other KIN-xxxxAP equipment.
[Preston A. Elder]
-
The 1.1kVA UPS is now supported by the bestuferrups driver. This
driver was also changed to allow easy addition of more models
in the future.
[Bob Apodaca]
-
The fentonups driver can now handle devices which implement the
"I" detection differently, and now supports the Giant/WELI 500
as a result.
[Joon Guillen]
-
The serial number of the UPS being monitored can now be specified
with serial= in ups.conf in the genericups driver.
[Shaul Karl]
-
The newapc driver now sends ESC to break out of menus when the
initial detection fails. Some new APC models have interactive menus
on the serial port, and the driver couldn’t handle them before.
-
The snmp-ups driver now reports ambient temperature and humidity
data for APC equipment. It also now supports the shutdown.reboot and
shutdown.reboot.graceful commands.
[Dmitry Frolov]
-
The list of supported variables and commands in the snmp-ups driver
has been expanded.
[Arnaud Quette, J.W. Hoogervorst]
-
Various drivers now report bypass mode with the BYP status word.
[Arnaud Quette]
-
Energy Sistem equipment is now supported with the esupssmart driver.
[Antonio Trujillo Coronado]
-
The Tripp-Lite SU series (SmartOnline) is supported with the new
tripplitesu driver.
[Allan Hessenflow]
-
The HP PowerTrust A2994A is now recognized by the hp driver.
[Jan Sporbeck]
-
Many drivers were cleaned up to perform basic sanity checks on the
status data before using it.
-
An explicit cleanup function has been added to the driver core to
ensure that all dynamic resources are freed before exiting. This
is part of the larger process to check for memory leaks and other
bad things.
[Arnaud Quette]
-
upsd now provides variable descriptions from an auxiliary file.
This file is optional, which allows for a smaller memory footprint.
It can also be edited for localization or other customizations.
-
upsimage and upsstats can now render BATTVOLT data.
[Andrew R. Ghali]
-
String handling has been cleaned up throughout the tree. Calls to
functions like strcpy and strcat were either replaced with other
(range-checking) functions or were rewritten to avoid it.
-
Many compile-time defaults may now be overridden at runtime. In
the environment NUT_CONFPATH and NUT_STATEPATH may be used.
upsdrvctl has been changed to execve to pass these along to the
drivers. ups.conf now supports driverpath=, and upsd.conf supports
DATAPATH.
[Bryan Henderson]
-
The configure --with-gd switches now actually do something useful
when gd has been installed outside the default search directories.
[Patrik Schindler]
-
The inline keyword is now handled properly on systems which do not
support it or have it specified as another name. This was breaking
compiles on some systems.
[Petter Reinholdtsen]
2.27. Release notes for NUT 1.2.2 - what’s new since 1.2.1
-
The snmp-ups driver has been upgraded and expanded. It now supports
multiple MIBs, meaning it can handle RFC 1628, APCC, and MGE
equipment. You can pick the right one with "mibs=" in ups.conf.
Support for setting variable and instant commands is also available.
[Arnaud Quette and Dmitry Frolov]
-
The powernet driver has been upgraded. It now supports more
variables, has cleaner logging, and may now be considered stable.
[Dmitry Frolov]
-
The hidups driver now supports physical port IDs. This avoids most
of the problems where the hiddev* names can jump around too easily.
It will now stay in the same place as long as you keep it plugged
into the same physical port. See the ChangeLog file for more details.
[David Brownell]
-
The hidups driver now also supports the MFR variable on APC
Back-UPS ES equipment.
[Jonathan A. Davis]
-
The sms driver has been updated to version 0.70.
[Marcio Gomes]
-
The bestups driver now recognizes Best Power Axxium Rackmount
equipment.
[Ales Casar]
-
The liebert driver now uses O_NONBLOCK, and should now work
consistently on OpenBSD as a result.
[Alex Cichowski]
-
The liebert driver also now uses debouncing logic on the status
lines. It was possible to get false readings that would start a
shutdown or just annoy users with excessive onbatt/online notify
messages. The new code forces the status to settle down for 3 polls
before accepting the new value.
This means that very short power events may not be detected. The
alternative is having your machine shut down just because it decided
to wiggle over to OB LB for a few seconds.
-
upsmon has had the disconnect logic fixed so the "communications
lost" (COMMBAD) notify will actually go out when the connection
fails.
[Steve Monett]
-
upssched now uses a lock file to prevent a race where two could
start at the same time. The second upssched would "win", and the
first one would be unreachable. This had the side-effect of not
being able to cancel timers on the first one.
If you use upssched, you must define the LOCKFN directive when
upgrading to this version, or it will not work.
[Gaspar Bakos]
-
The packaging and scripts for Red Hat systems have been updated.
[Antonino Albanese]
-
upsd is now a bit more lenient about access levels in the
numlogins check, which is what caused the problem in upsmon
(next item).
-
upsmon no longer gets stuck in slavesync() when upsd is configured
to drop certain queries. This usually happened at the worst
possible time: in the middle of a shutdown.
[John David Garza]
-
The upsclient functions now do more sanity checking on data from
upsd so a short read won’t return garbage to the callers.
-
upsset now works properly with ENUM/VARTYPE values for multiple
UPSes on a single upsd.
[Dmitry Frolov]
-
Various portability fixes for building on SGI were applied.
[Andrea Suatoni]
-
upsd no longer tries to reference a deleted client structure if the
client disconnects at the wrong time. Previously, it tried to use
that pointer after the sendback() function had already failed on
write and deleted the client. This could cause upsd to segfault
depending on what areas were accessed.
[Patrik Schindler]
2.28. Release notes for NUT 1.2.1 - what’s new since 1.2.0
-
The sms driver is back, with support for Microlink Manager III
hardware. [Marcio Gomes]
-
Fideltronik Ares Series hardware is now supported as genericups
type 19. [Tomek Orzechowski and Arkadiusz Mikiewicz]
-
The drivers no longer silently drop instant commands or set commands
from upsd that happen to get fragmented in transit.
[linux@horizon.com]
-
The old multilink driver is back with a new name: liebert. It
supports Liebert UPStation GXE hardware with the contact-closure
cable. This is currently an experimental driver as there is no
way to power down the load.
-
configure now picks up the right flags for gd automatically if gd
2.0.8 or higher is installed. This greatly simplifies the CGI build
process for most users.
-
Shutdowns on FreeBSD using the genericups driver should work again.
[Petri Riihikallio]
