upsset.cgi - Web‐based UPS administration program
As a CGI program, this should be invoked through your web server. If
you run it from the command line, it will sit there until you give it
input resembling a POST request.
upsset.cgi lets you access many administrative functions within the UPS
software from your web browser. You can change settings and invoke
instant commands where available.
Some UPS hardware allows you to change certain variables to other
values. To see what’s available, pick a UPS from the chooser and
select "settings", then select "View" to update the page.
You should see a list of items with the descriptions on the left side
and the possible options or input spaces on the right. After changing
something, be sure to "Save changes" to update the values in your UPS.
If your UPS doesn’t support any read/write variables, there will be
nothing to do on this page.
Setting values in read/write variables can also be done from the
command line with upsrw(8).
Some UPS hardware also has provisions for performing certain actions at
the user’s command. These include battery tests, battery calibration,
front panel tests (beep!) and more. To access this section, do as
above, but pick "Commands" as the function.
If your UPS supports any instant commands, they will be listed in a
chooser widget. Pick the one you like and "Issue command" to make it
Note ‐ some dangerous commands like "Turn off load" may not happen
right away. This is a feature, not a bug. The apcsmart driver and
some others require that you send this command twice within a short
window in order to make it happen. This is to keep you from
accidentally killing your systems by picking the wrong one.
To actually turn off the load, you have to send the command once, then
send it again after 3 seconds elapse but before 15 seconds pass. If
you do it too quickly or slowly, you have to wait at least 3 seconds
but not 15 seconds again.
You can also invoke instant commands from the command line with
upsset will only talk to upsd(8) servers that have been defined in your
hosts.conf(8). If it complains about "Access to that host is not
authorized", check your hosts.conf first.
upsset will not run until you convince it that your CGI directory has
been secured. This is due to the possibility of someone using upsset
to try password combinations against your upsd(8) server.
See the example upsset.conf file for more information on how you do
this. The short explanation is ‐ if you can’t lock it down, don’t try
to run it.
