    NAME

    upscmd - UPS administration program for instant commands
     
    

    SYNOPSIS

    upscmd -h

    upscmd -l ups

    upscmd [-u username] [-p password] ups command

     

    DESCRIPTION

    upscmd allows you to invoke "instant commands" in your UPS hardware. Not all hardware supports this, so check the list with -l to see if anything will work on your equipment.

    On hardware that supports it, you can use this program to start and stop battery tests, invoke a front panel test (beep!), turn the load on or off, and more.

     

    OPTIONS

    -h
    Display the help message.

    -l ups
    Show the list of supported instant commands on that UPS. Some hardware may not support any of them.

    -u username
    Set the username for the connection to the server. This is optional, and you will be prompted for this when invoking a command if -u is not used.

    -p password
    Set the password to authenticate to the server. This is also optional like -u, and you will be prompted for it if necessary.

    ups
    Connect to that UPS. The format for this option is [upsname@]hostname[:port].

     

    UNATTENDED MODE

    If you run this program inside a shell script or similar to invoke a command, you will need to specify all of the information on the command line. This means using -u and -p. Otherwise it will put up a prompt and your program will hang.

    This is not necessary when displaying the list, as the username and password are not required for read-only mode.

     

    DANGEROUS COMMANDS

    Some drivers like apcsmart(8) have built-in paranoia for the dangerous commands like OFF. To make them actually turn off the load, you will have to send the command twice within a short window. That is, you will have to send it once, then send it again after 3 seconds elapse but before 15 seconds pass.

    This paranoia is entirely defined within the driver. upsd and upscmd have no control over the timing.

     

    DIAGNOSTICS

    upscmd won't work unless you provide a valid username and password. If you get "access denied" errors, make sure that your upsd.users(5) has an entry for you, and that the username you are using has permissions to SET variables.

     

    BUGS

    There is currently no way to tell the user when the driver requires confirmation to invoke a command such as OFF. Similarly, there is not yet a way to tell the user if a command succeeds or fails.
