       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

       Setting values in read/write variables can also be done from the command line with


       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 happen.

           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 upscmd(8).


       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.
