Imported Upstream version 2.6.0
2011-01-26 09:35:08 +00:00
---------------------------------------------------------------------------
Release notes for NUT 2.6.0 - what's new since 2.4.3:
- the main focus of this release is the complete documentation revamping,
using AsciiDoc. This includes a new website, user manual, developer guide,
packager guide and manual pages, available in various formats (single and
multiple pages HTML, and PDF at the moment).
Be sure to check the --with-doc configure option help, and
docs/configure.txt for more information.
- Add Augeas support, to provide easy NUT configuration management, through
tools and development APIs. For more information, refer to the developer
guide, or scripts/augeas/README in the source directory.

---------------------------------------------------------------------------
Release notes for NUT 2.4.0 - what's new since 2.2.2:
- preliminary support for Power Distribution Units (PDUs): NUT now support
PDUs, either natively (ie using NUT snmp-ups driver), or through a binding to
the Powerman daemon. The list of supported PDUs is already quite long,
including: Eaton ePDUs (Managed and Monitored), some Aphel models, some
Raritan PDUs, and the whole list of Powerman supported devices:
http://powerman.sourceforge.net/supported.html
- support for new devices: the various PDUs cited above, Chloride Desk Power
650, Cyber Power Systems Value 400E/600E/800E (USB models), Delta GES602N,
Digitus DN-170020, the whole Eaton ranges (mostly composed of MGE Office
Protection Systems and Powerware units) including BladeUPS, Forza Power
Technologies SL-1001, HP PowerTrust 2997A, HP R/T 2200 G2, Infosec XP 1000
and XP 500, Ippon Back Power Pro (serial and USB), Kebo 1200D/D Series,

NUT-Monitor application. Both are from David Goncalves, and are still
available from http://www.lestat.st.
For more information, refer to scripts/python/README.
- the dummy-ups driver now support a "repeater" mode. This allows it to act as
a NUT client, and to forward data. This can be useful for supervision and
load sharing purposes.
- tcp-wrappers support has been added to the upsd server, to grant users access
by source IP for commands that require to be logged into the server. This
replaces the previous internal implementation (ACL in upsd.conf).
- the nut.conf file has been introduced to standardize startup configuration
across the various systems.
- NUT now ships a bash completion function for 'upsc' command
(scripts/misc/nut.bash_completion). Simply copy it to /etc/bash_completion.d
- many internal changes to improve maintenability, while lowering the
maintenance cost (thus allowing developers to focus on what matters: the
code!). Examples of this are:
- the USB information automatic extraction to generate the various USB helper
files,
- the upsdrv_info_t structure to track more driver information, and remove
the need for the upsdrv_banner() function
- common USB code refactoring, as it is done for the serial functions.
- tons of bugfixes, cleanup and improvements to make NUT stronger than ever!
---------------------------------------------------------------------------

[Ulf Harnhammar]
---------------------------------------------------------------------------
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 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).
---------------------------------------------------------------------------
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 use 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.
MONITOR ups-1@host-1 ...
MONITOR ups-1@host-2 ...
MONITOR ups-2@host-2 ...
MONITOR ups-3@host-3 ...
Connection reuse for nonadjacent entries may be considered in the
future.
- 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]
---------------------------------------------------------------------------
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]
---------------------------------------------------------------------------
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.
