IOT Link - Windows Management using MQTT

DivanX10 · June 15, 2022, 9:44pm

Hotlink sensors are sometimes unavailable. To fix this, I restart the IOTLink service and the sensors start working again. This happens quite often and I was thinking about automatically restarting the IOTLink service. The IOTLink service itself works and standard sensors do not fail. It is user sensors that fail, for example Process Monitor. I created a batnik and run it to restart the IOTLink service, but I ran into a problem. Elevated permissions are required to run the batnik.

In c:\ProgramData\IOTLink\Addons\ProcessMonitor\apps\Games.yaml I added the following

processes:
  - ACValhalla.exe
  - DOOMEternalx64vk.exe
  - HorizonZeroDawn.exe
  - HaloInfinite.exe
  - RAGE2.exe
  - GoW.exe
  - MetroExodus.exe
windows:
classnames:
configs:
  enabled: true
  discoverable: true
  advancedMode: false
  displayName: Games
  cacheable: true
  grouped: true
  compareType: 0
  interval: 10

I wrote a batnik that restarts the IOTLink service, but there is a problem, the batnik does not start, since elevated rights and UAC bypass are required. I found an option and wrote it like this, the option is below

This batnik cannot start because administrator rights are required

@echo off
net stop IOTLink
rem
net start IOTLink

This batnik runs with administrator rights via IOTLink, but does not bypass UAC, you have to turn off UAC.


@echo off

:: BatchGotAdmin
:-------------------------------------
REM  --> Check for permissions
    IF "%PROCESSOR_ARCHITECTURE%" EQU "amd64" (
>nul 2>&1 "%SYSTEMROOT%\SysWOW64\cacls.exe" "%SYSTEMROOT%\SysWOW64\config\system"
) ELSE (
>nul 2>&1 "%SYSTEMROOT%\system32\cacls.exe" "%SYSTEMROOT%\system32\config\system"
)

REM --> If error flag set, we do not have admin.
if '%errorlevel%' NEQ '0' (
    echo Requesting administrative privileges...
    goto UACPrompt
) else ( goto gotAdmin )

:UACPrompt
    echo Set UAC = CreateObject^("Shell.Application"^) > "%temp%\getadmin.vbs"
    set params= %*
    echo UAC.ShellExecute "cmd.exe", "/c ""%~s0"" %params:"=""%", "", "runas", 1 >> "%temp%\getadmin.vbs"

    "%temp%\getadmin.vbs"
    del "%temp%\getadmin.vbs"
    exit /B

:gotAdmin
    pushd "%CD%"
    CD /D "%~dp0"



@echo off
net stop IOTLink
rem
net start IOTLink

Tried using runas, also doesn’t help

runas /user:user "c:\scripts\iotlink_reboot.bat"

Running the script via IOTLink looks like this

service: mqtt.publish
data:
  topic: iotlink/workgroup/livingroom/commands/run
  payload: >-
    { "command": "C:\\scripts\\iotlink_reboot.bat", "path": "C:\\scripts",
    "user": "", "visible": false, "fallback": true }
