User's Manual UPS control system

you to do this include one command-line utility (apcaccess) and a GUI you
can use through a Web browser. You can also use apctest to tune some
parameters of the UPS itself.
apcaccess
apcaccess is a program (normally found in /sbin/apcaccess) that permits you
to print out the complete status of your UPS. Although there are a number
of command line arguments (eprom, reconfig, status, slave, shutdown),
all except eprom and status are under development and hence do not work
reliably.
If you have built apcupsd with pthreads enabled (default), apcaccess will use
the Network Information Server to obtain the necessary information for the
status and eeprom commands. This is because in the pthreaded version,
there is no IPC shared memory. In this case (pthreads enabled), you can
specify a second optional argument to apcaccess in the form of host:port,
where the :port is optional. The default is localhost:3551. Please note
that in versions prior to 3.10.6, the default NIS port was 7000, so if you
are mixing versions, you will need to take a lot of care to ensure that all
components are using the same port.
To enable the apcupsd Network Information Server, which is normally the
default, you set:
NETSERVER on
NISPORT 3551
in your apcupsd.conf file.
apcaccess status:
As mentioned above, the full form of the command is:
apcaccess status localhost:3551
where only apcaccess status should normally be needed. localhost may be
replaced by any machine name, fully qualified domain name, or IP address,
