Windows Update Stop!

The people at novirusthanks.org made a free product called WinUpdateStop.  It is an active service that persistently prevents Windows updates from happening.  Yes, you could disable Windows services and do registry things, but this is a more active approach.  And it has a nice interface allowing you to easily enable or disable updates.

The software was free up until March of 2021 with version 1.4.  As of version 1.5 it is a paid product requiring an annual subscription.  Out of respect to the work of the authors I won't provide a link to v1.4, but I'm happy I always keep copies my downloads.

Do check out the novirusthanks.org web site.  They have dozens of interesting utility programs and services, some security related and some not.

Free MIB Browser

I've tried a number of free MIB browsers and like ManageEngine's MibBrowser the best.  It handles tables well, for one thing, where most of the others don't handle them at all.

Free (really) dynamic DNS

I switched to dynu.com's free dynamic DNS service.  (I used to use noip.com, but ran into some restrictions.)  Try dynu,com, they've been great.

IPMITool for Windows

Here is a link to Dell's web site to download IPMITool for Windows.

Here is a link to my own copy if that link breaks.

Example Batch files

1. Get Device List

@echo off

cd "C:\Program Files (x86)\Dell\SysMgt\bmc"

ipmitool.exe -I lanplus -H 10.0.0.1 -U sysadmin -P ****** sdr list

2. Get Fan Speed

@echo off

cd "C:\Program Files (x86)\Dell\SysMgt\bmc"

REM get fan speeds, exhaust temp
ipmitool.exe -I lanplus -H 10.0.0.1 -U sysadmin -P ****** sensor reading "Fan1 RPM" "Fan2 RPM" "Fan3 RPM" "Fan4 RPM" "Fan5 RPM" "Fan6 RPM" "Exhaust Temp"

3. Example of: Set Fan Speed to manual, set desired speed (as a percentage), set fan speed back to automatic.  Fans take a few seconds to change speed after setting, be patient.  Fan setting reverts to 'automatic' on reboot.  :(

@echo off

cd "C:\Program Files (x86)\Dell\SysMgt\bmc"

REM Set fan speed control to manual, overriding automatic
ipmitool -I lanplus -H 10.0.0.1 -U sysadmin -P ****** raw 0x30 0x30 0x01 0x00

REM Set fan speed to 40% of max (0x28 is hexadecimal for 40)

ipmitool -I lanplus -H 10.0.0.1 -U sysadmin -P ****** raw 0x30 0x30 0x02 0xff 0x28

REM Set fan speed to 30% of max (0x1e is hexadecimal for 30)
ipmitool -I lanplus -H 10.0.0.1 -U sysadmin -P ****** raw 0x30 0x30 0x02 0xff 0x1e

REM Set fan speed control to automatic

ipmitool -I lanplus -H 10.0.0.1 -U sysadmin -P ****** raw 0x30 0x30 0x01 0x01
