upsd.users - Administrative user definitions for NUT upsd


Administrative commands such as setting variables and the instant commands are powerful, and access to them needs to be restricted. This file defines who may access them, and what is available.

Each user gets its own section. The fields in that section set the parameters associated with that user's privileges. The section begins with the name of the user in brackets, and continues until the next user name in brackets or EOF.

Here are some examples to get you started:

                 password = mypass
                 actions = set
                 instcmds = all
                 password = duh
                 instcmds = test.panel.start
                 password = blah
                 upsmon master
                 password = abcd
                 upsmon slave



Set the password for this user.


Allow the user to do certain things with upsd. Valid actions are:

        SET - change the value of certain variables in the UPS

        FSD - set the forced shutdown flag in the UPS. This is
equivalent to an "on battery + low battery" situation for the purposes of monitoring.

The list of actions is expected to grow in the future.


Let a user initiate specific instant commands. Use "ALL" to grant all commands automatically. For the full list of what your UPS supports, use "upscmd -l".

The cmdvartab file supplied with the distribution contains a list of most of the known command names.


Add the necessary actions for a upsmon process to work. This is either set to "master" or "slave".

Do not attempt to assign actions to upsmon by hand, as you may miss something important. This method of designating a "upsmon user" was created so internal capabilities could be changed later on without breaking existing installations.


The allowfrom mechanism that existed in versions before nut-2.4.0 has been replaced by tcp-wrappers. Further details are described in upsd(8).
