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\(cqs privileges. The section begins with the name of the user in brackets, and continues until the next user name in brackets or EOF. These users are independent of /etc/passwd.
Here are some examples to get you started:
[admin]
password = mypass
actions = set
actions = fsd
instcmds = all
[pfy]
password = duh
instcmds = test.panel.start
instcmds = test.panel.stop
[monmaster]
password = blah
upsmon master
[monslave]
password = abcd
upsmon slave
password
Set the password for this user.
actions
Allow the user to do certain things with upsd. To specify multiple actions, use multiple instances of the actions field. 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.
instcmds
Let a user initiate specific instant commands. Use "ALL" to grant all commands automatically. To specify multiple commands, use multiple instances of the instcmds field. 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.
upsmon
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.
