Automatically shutting down an ESXi 6.7+ server from a CyberPower UPS using the PowerPanel Business Edition 4.x

Posted by jpluimers on 2021/07/09

Unlike the name PowerPanel Business Edition, this is a free tool. It allows you to manage your CyberPower UPS and to shutdown various systems, including an ESXi host.

It took CyberPower from version 3.3 to version 4.0 of the PowerPanel software to support ESXi 6.7. Reason was that VMware ESXi 6.5 was the latest version supporting vMA:

Below the steps to get PowerPanel 4.x up and running on ESXi 6.7+.

First of all, you have to ensure your CyberPower is connected to ESXi via USB.

Then you need to download and install the CyberPower virtual appliance “PowerPanel Business”

When the appliance runs, you have to virtually plugin the USB.

Finally configure the virtual appliance.

If you think everyone has such an organised life, and you feel so lost

Posted by jpluimers on 2021/07/09

Deelnemer in workshop: het lijkt wel alsof iedereen gewoon precies weet waar die mee bezig is en ik doe maar wat.

Ik aan andere deelnemers: wie van jullie klooit ook gewoon maar wat aan???

Iedereen (including me):

It does not translate well into English (though good translations are welcome), but comes down to this:

Workshop participant: it feels like everybody knows what they are doing, and I just try and try and try.

Me to all participants: who is doing trial-and-error?

Everybody (including me): raises hand.

Which basically is my life in one sentence.

I’m autodidact. I have virtually taught myself most things I know to date by just doing them and trying to solve the problems that came on my path, reaching out to the interwebs (and previously: books, magazines, mailing lists, word of mouth) whenever got really stuck.

Obtaining system information from SMB – Nmap: Network Exploration and Security Auditing Cookbook – Second Edition

Posted by jpluimers on 2021/07/09

Based on

This scans the network for SMB capable machines, and extracts information from them:

nmap -p139,445 --script smb-os-discovery

Note that experimenting this, I found out that nmap is also available on Chocolatey: [WayBack] Chocolatey Gallery | Nmap 7.70 (heck, since 2016, no less!).

I was hoping I wrote a little batch file around this, called, because net view is working not so well on Windows 10 any more, but that failed, so here is the batch file:

@echo off
:: only works from older versions than Windows 10
:: the delay is caused by the "net view" scanning the network
:: the first for calls ping with the hostname
:: the second for gets the IP and hostname without waiting for a ping result
for /f "usebackq tokens=1* delims=\ " %%m in (`net view ^| findstr "\\"`) do (
  for /f "usebackq tokens=2,3 delims=[] " %%h in (`ping -4 %%m -n 1 -w 1 ^| grep Pinging`) do (
    echo %%i    %%h
goto :eof

:: output of the first for without filtering (no starting newline):
:: Server Name            Remark
:: -------------------------------------------------------------------------------
:: \\REVUE                Samba 4.7.3-git.30.54c196e5d35SUSE-oS15.5-x86_64
:: \\VCS-CI
:: The command completed successfully.

:: output of the second for without filtering (including the starting newline):
:: Pinging revue [] with 32 bytes of data:
:: Reply from bytes=32 time<1ms TTL=64
:: Ping statistics for
::     Packets: Sent = 1, Received = 1, Lost = 0 (0% loss),
:: Approximate round trip times in milli-seconds:
::     Minimum = 0ms, Maximum = 0ms, Average = 0ms

The above batch file delivered many more results than this line:

nmap -p139,445 --script smb-os-discovery | grep -w "\(report\|Computer name\)"
