NAME¶
upsset.cgi - Web-based UPS administration program
SYNOPSIS¶
upsset.cgi
Note
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.
DESCRIPTION¶
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.
CHANGING SETTINGS¶
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).
INSTANT COMMANDS¶
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.
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
upscmd(8).
ACCESS CONTROL¶
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.
SECURITY¶
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.
FILES¶
hosts.conf(5),
upsset.conf(5)
