Windows 98 and Windows NT version of Apcupsd
General
The Windows version of apcupsd has been tested on both
Win95/98 and WinNT systems. It should also work on Win2000 systems
in the same way it does on WinNT systems.
This version of apcupsd has been
built to run under the CYGWIN environment, which provides many of
the features of Unix on Windows systems. It also permitted a rapid port
with very few changes, which means that the Windows version is for
the most part running code that has long proved stable on Unix systems.
Even though the Win32 version of apcupsd is a port that relies on
many Unix features, it is just the same a true Windows program. When running,
it is perfectly integrated with Windows and displays its icon in the
system icon tray, and provides a system tray menu to obtain additional
information on how apcupsd is running (status and events dialogue
boxes). If so desired, it can also be stopped by using the system tray
menu, though this should normally never be necessary.
Once installed apcupsd normally runs as a system service. This
means that it is immediately started by the operating system when the
system is booted, and runs in the background even if there is no user
logged into the system.
Installation
Normally, you will install the Windows version of Apcupsd from the
binaries, which come in two forms. One is an InstallShield standard
Windows install. You simply execute the apcupsd setup.exe program
and follow the instructions. The advantage of this method is that
it can be easily uninstalled and a menu item is put into the
Program item of the Start menu.
The second binary install is more Unix like since you
do many parts of the installation by hand.
To install the binaries by this method, you need WinZip.
- Simply double click
on the winapcupsd.tar.gz icon.
- When Zip says that it has one file and asks if it should unpack it
into a temporary file, respond with Yes.
- Ensure that you extract all files and that the extraction will go
into C:\
If you wish to install the package elsewhere, please note that you will need
to proceed with a manual installation, which is not particularly
easy as you must rebuild the source and change the configuration file as well.
This installation assumes that you do not
have CYGWIN installed on your computer. If you do,
and you use mount points, you may need to do a special manual installation.
Once you have unzipped the binaries, open a window pointing to
the binary installation folder (normally c:\apcupsd). This
folder should contain folders with the name bin, etc, examples, and manual.
If and when you no longer need them, the examples and manual sub-folders
of the c:\apcupsd directory may be removed.
Continuing the installation process:
- Open the directory c:\apcupsd\etc\apcupsd in the Windows Explorer by
Clicking on the apcupsd folder then on the etc folder,
then on the apcupsd folder. Finally
double click on the file apcupsd.conf and edit it to contain the
values appropriate for your site. In most cases, no changes will
be needed, but if you are not using com1 for your serial port,
you will need to set the DEVICE configuration directive to
the correct serial port.
- Then return to c:\apcupsd and open on the bin
folder so that you see its contents.
- To do the final step of installation, double click on the setup.bat
program. This script will setup the appropriate mount points for the
directories that apcupsd uses, it will install apcupsd in the
system registery, and on Windows 98, it will start apcupsd running.
If everything went well, you will get something similar to the following output in a
DOS shell window:
What is important to verify in the DOS window is that the root
directory \ is mounted on device c:\.
The DOS window will be followed immediately by a Windows dialogue box as follows:
- On Windows 98, to actually start the service, either reboot
the machine, which is not necessary, or open a DOS shell window,
and type the following commands:
cd c:\apcupsd\bin
apcupsd /service
Alternatively, you can go to the c:\apcupsd\bin folder with the
Explorer and double click on the Start icon.
- On Windows NT, to start the service, either reboot
the machine, which is not necessary, or go to the Control Panel,
open the Services folder and start
the Apcupsd daemon program by selecting the
Apcupsd UPS Server and then clicking on the Start button as shown
below:
That should complete the installation process. When the system tray icon
turns from a battery
into a
plug
, right click on it
and a menu will appear. Select the Events item, and the Events dialogue box
should appear. There should be no error messages. By right clicking again on the
system tray plug and selecting the Status item, you can verify that all the
values for your UPS are correct.
When the UPS switches to the battery, the battery icon will reappear in the
system tray. While the UPS is online, if the battery is not at least 99% charged,
the plug icon will become a plug with a lightning bolt in the middle
to indicate
that the battery is charging.
Installation Directory
No matter which method you choose for installing the Win32 apcupsd,
it must reside in the c:\apcupsd\ directory, and there must
be a c:\tmp directory on your machine. Both methods accomplish
this automatically, and we recommend that you do not attempt
to place apcupsd in another directory. If you do so, you
are on your own, and you will need to do a rebuild of the source.
Testing
It is hard to over emphasize the need to do a full testing of
your installation of apcupsd as there are a number of
reasons why it may not behave properly in a real power failure
situation.
Please read the Testing chapter of this
document for general instructions on testing the Win32 version. However, on
Win32 systems, there is no Unix system log file, so if something goes
wrong, look in the file c:\apcupsd\etc\apcupsd\apcupsd.events
where apcupsd normally logs its events, and
you will generally find more detailed information on why the program is
not working. The most common cause of problems is either improper configuration
of the cable type, or an incorrect address for the serial port.
Upgrading
On Win98 and Win95 systems, to upgrade to a new release, simply stop
apcupsd by using the tray icon and selecting the Close Apcupsd
menu item, or by double clicking on the Stop icon located in
the c:\apcupsd\bin directory, then apply the upgrade and
restart apcupsd.
On WinNT systems (and possibly Win2000 systems), you must stop
apcupsd by using the Services item in the Control Panel.
In addition, at least on my system, there seems to be a WinNT bug that
causes the system to prevent apcupsd.exe from being overwritten
even though the file is no longer being used. This is manifested by an
error message when attempting load a new version and overwrite the old
apcupsd.exe. To circumvent this problem (if it happens to you),
after shutting down the
running version of apcupsd, through the Services dialogue
in the Control Panel, first click on the Stop button:
then click on the Startup ... button, and in the Startup dialogue
select the Disabled button to disable apcupsd:
After closing the dialogues, reboot the system, typical of Microsoft :-(.
When the system comes backup, apcupsd will not
be automatically launched as a service, and you can install the new version.
To reinstate apcupsd as an automatic service, using the Control Panel:
reset apcupsd to Automatic startup
in the Startup dialogue, then restart apcupsd in the Services
dialogue as shown above in the installation instructions.
Postinstallation
After installing apcupsd and before running it, you should check the contents of two
files to ensure that it is configured properly for your system. The first
is c:\apcupsd\etc\apcupsd\apcupsd.conf. You will probably need to change
your UPSCABLE directive, your UPSTYPE and possibly your DEVICE directives.
Please refer to the configuration section of this manual for more details.
The second file that you should examine is c:\apcupsd\etc\apcupsd\apccontrol.
This file is called by apcupsd when events (power loss, etc) are generated. It permits the user
to program handling the event. In particular, it permits the user to be notified
of the events. For the Win32 version, each event is programmed to display
a Windows popup dialogue box. If your machine is mostly unattended, you may
want to comment out some of these popup dialogue boxes by putting a pound
sign (#) in column one of the appropriate line.
Problem Areas
In addition to possible problems of reinstallation or upgrade on WinNT
systems, as noted above, we have discovered the following problem:
On all Windows systems, the domain resolution does not seem to work. This
problem should be apparent only when running a master or a slave configuration.
In this case, when you specify the name of the master or the slave machine(s)
in your apcupsd.conf file, apcupsd will be unable to resolve the
name to a valid IP address. To circumvent this problem, please enter all
machine addresses as an IP address rather than a domain name. For example,
instead of using the directive:
MASTER my.master.com
use something like:
MASTER 192.168.1.54
where you replace the IP address with your actuall IP address.
Utility Functions
The directory c:\apcupsd\bin contains six utility routines (actually
.pif files) that you may find useful. They are:
Start
Stop
Install
Uninstall
ups-events
ups-status
Any of these utilities may be used on any system, with the exception of
the Start utility, which cannot be used on WinNT and Win2000 systems.
On those systems, the apcupsd service must always be started through
the Services sub-dialogue of the Control Panel.
The Install and Uninstall utilities install and uninstall
apcupsd from the system registery only. All other pieces (files) of
apcupsd remain intact. It is not absolutely necessary for apcupsd
to be installed in the registry as it can run as a regular program. However,
if it is not installed in the registry, it cannot be run as a service.
The functions of Stop, ups-events, and ups-status
can be more easily invoked by right clicking on the acpupsd icon
in the system tray and selecting the desired function from the popup menu.
Disclaimer
This Windows version of apcupsd is the first release. It
has been rather extensively tested, so it is known to work. However,
it has not been installed at many sites, so there may be some
minor difficulties during the installation process. In addition,
since it is a new system port, there may be features that have
not been tested (for example, not tested: doing a full power down of the
UPS, programming the EEPROM, or with a "dumb" UPS).
It has, however, been tested on Win95, Win98, and WinNT in standalone mode as well
as slave mode (to a Linux server). If at all possible, we recommend
not to use it as a network master on Win95 and Win98 due to the
instability of those operating systems. If you do use it in any configuration
not mentioned here, please send us an email with your experiences.
Some items to note:
- This version of apcupsd will not attempt to shut off
the UPS power when the battery is exhausted. Thus if the power
returns before the UPS completely shuts down, your computer may
not reboot automatically.
- When apcupsd detects important events, it calls
c:\apcupsd\etc\apcupsd\apccontrol, which is a Unix shell
script. You may modify this script to suit your particular needs.
Currently, it puts a Windows dialogue on the screen with a brief
explanation of the event. If these dialogues annoy you, you can
remove or comment out the calls to popup from this file.
Email Notification of Events
On Win95/98 systems, it is possible to receive notification
of apcupsd events that are passed to apccontrol.
This is possible using a simple email program that unfortunately
is not functioning 100% correctly. In addition, I (Kern) was
not able to make this program work on WinNT while apcupsd is
running as a service under the system account (it works fine
with any user account).
If you wish to try this program on Win95/98 systems, look
at the files named changeme, commfailure, commok,
onbattery, and mainsback in the directory c:\apcupsd\examples.
To use them, you must modify the SYSADMIN variable to have a
valid email address, then copy the files into the directory
c:\apcupsd\etc\apcupsd.
Command Line Options Specific to the Windows Version
These options are not normally seen or used by the user, and are
documented here only for information purposes. At the current time,
to change the default options, you must either manually run apcupsd
or you must manually edit the system registry and modify the appropriate
entries.
In order to avoid option clashes between the options necessary for
apcupsd to run on Windows and the standard apcupsd options,
all Windows specific options are signaled with a forward slash character (/),
while as usual, the standard apcupsd options are signaled with a minus (-),
or a minus minus (--). All the standard apcupsd options can be used on
the Windows version. In addition, the following Windows only options are
implemented:
- /servicehelper
- Run the service helper application
- /service
- Start apcupsdas a service
- /run
- Run the apcupsd application
- /install
- Install apcupsd as a service in the system registry
- /remove
- Uninstall apcupsd from the system registry
- /about
- Show the apcupsd about dialogue box
- /status
- Show the apcupsd status dialogue box
- /events
- Show the apcupsd events dialogue box
- /kill
- Stop any running apcupsd
- /help
- Show the apcupsd help dialogue box
It is important to note that under normal circumstances the user should never
need to use these options as they are normally handled by the system automatically
once apcupsd is installed. However, you may note these options in
some of the .pif files that have been created for your use.
Because I have not yet figured out how to execute apcupsd after
the system shutdown and before the system halt, there is as of this moment
no way for apcupsd to cause the UPS to shut off the power. This means
that if the UPS does not automatically shutdown, and the power returns, your
system will not be automatically rebooted. This could be resolved by the use of the
--kill-on-powerfail option, but the use of this option could cause the
power to be cut off while your machine is still running. See the section on
Shutdown Sequence in the testing chapter
of this document for a more complete discussion of this subject. If you are
still interested in trying to get this to work, please look at the code
that is commented out in c:\apcupsd\etc\apcupsd\apccontrol under the
doshutdown case.
Building the Win32 Version from the Source
If you have the source code, follow the standard procedures for
building apcupsd on Unix in the Installation Section of
this manual. Please don't forget to look at the
Win32 specific instructions.
