Dave Anderson on Twitter: “Cool minor @Tailscale moment: I’m recommissioning a server that got moved from a different network, so all its network config was wrong, and generally I couldn’t get at it over the network, only IPKVM console. But then my `ping` over Tailscale started working?!” / Twitter

Wow, I wrote about Tailscale a few times before, and it is still on my research list, but this is a very compelling reason to use it. [Archive] Dave Anderson on Twitter: “Cool minor @Tailscale moment: I’m recommissioning a server that got moved from a different network, so all its network config was wrong, and generally I couldn’t get at it over the network, only IPKVM console. But then my ping over Tailscale started working?!” / Twitter

I archived the thread so it becomes easier to read: [Wayback/Archive] A readable Thread by @dave_universetf Says Cool minor @Tailscale moment: I’ – UnrollThread.com.

The core are these three tweets:

Turns out, IPv6 autoconfiguration is what happened. Sure, v4 configuration was entirely wrong (it was trying to connect to wifi, via a wifi dongle that was no longer installed, and wanted to talk to a DNS server that doesn’t exist any more), but eno1 had a cable plugged in!
The server noticed IPv6 router advertisements, went “I’ll have some of that”, and got global IPv6 connectivity automagically. IPv4 and DNS were still down though, so all it had at this point is the ability to send/receive IPv6 packets.
So, how did Tailscale get from there to a working setup? It still needs to contact https://t.co/hEs4S8qvTw to get a network map, and still needs to talk to DERP servers to get p2p tunnels working outside the LAN. Enter bootstrap DNS!

It means I have to re-read Source: Some links on Tailscale / Wiregard, especially the [Wayback] How Tailscale works · Tailscale bit, then decide how I want to organise my infrastructure to run parts under Tailscale (I have the impression it is a peer based set-up, not router based).

Then I have to read [Wayback/Archive] IPv4, IPv6, and a sudden change in attitude – apenwarr of which the conclusion is this:

IP mobility is what we do, in a small way, with Tailscale’s WireGuard connections. We try all your Internet links, IPv4 and IPv6, UDP and TCP, relayed and peer-to-peer. We made mobile IP a real thing, if only on your private network for now. And what do you know, the math works. Tailscale’s use of WireGuard with two networks is more reliable than with one network.

Finally I need to not just read it, but understand all it (:

Or maybe I should ask Kris, as I got here through:

I saved Kris’ message thread here at [Wayback/Archive] Thread by @isotopp on Thread Reader App – Thread Reader App.

Installing Windows OpenSSH from the command-line on Windows 10 and 11

Posted by jpluimers on 2023/03/28

While writing On my reading list: Windows Console and PTY, I found out that OpenSSH had become available as an optional Windows feature.

It was in [Wayback/Archive.is] Windows Command-Line: Introducing the Windows Pseudo Console (ConPTY) | Windows Command Line:

Thankfully, OpenSSH was recently ported to Windows and added as a Windows 10 optional feature. PowerShell Core has also adopted ssh as one of its supported PowerShell Core Remoting protocols.

Here are a few links:

Windows: investigating error code 0x80073701 and 0x800f081f while updating; some DISM and CBS log things to search for

Posted by jpluimers on 2023/03/20

A while ago when applying KB5008212* through Windows Update, I got errors. It was odd, as until now, all other upgrades had worked fine.

Often Windows update errors are because of lack of disk space (I try maintain 10 gigabytes or more free space on virtual machines, but that sometimes fails because some software – despite user files being on a different drive – sometimes insists on filling the system drive).

This time, Windows Update would show 0x80073701, of course right after reaching 100%, but actually it was a 0x800f081f  in disguise.

My usual modus operandi didn’t solve it (with a retry after every step):

  1. Reboot
  2. Cleanup of the system drive using built-in CleanMgr.exe (Disk cleanup)
  3. Scan all corrupted system files and replace them from cache: SFC /ScanNow (System File Checker)
  4. Cleanup and repair the Windows image using DISM /Online /Cleanup-image /Restorehealth (Deployment Image Servicing and Management)

All failed, but in the last step, DISM would consistently show error 0x800f081f.

Even a local DISM /Online /Cleanup-Image /RestoreHealth /Source:C:\Windows\WinSxS /LimitAccess would fail.

Each DISM run will actually log in two log files, and this is the trick to figure out what the next step would be.

Examples from my case:

Some links I on Windows Memory Compression I want to check out

Posted by jpluimers on 2023/01/24

I’m not sure yet why sometimes my system is lagging with the combination of these four circumstances on a Windows 10 system with 32 gigabyte of memory:

  1. Process Explorer showing low (less than 10%) CPU usage
  2. Process explorer showing Memory Compression using more than 2 gigabytes of Working Set
  3. System Commit being larger than 20 gigabyte
  4. Lots of Chrome tabs open (no easy way to total memory usage, but likely 16 gigabyte or more)

Windows Compression was introduced in Windows 10 (back in 2015) and I’m still fairly new to it.

So here are some links I want to eventually dig into to make myself more familiar with it, and see if it affects Chrome runtime behaviour:

Thanks [Wayback/Archive] magicandre1981, [Wayback/Archive] peterh, [Wayback/Archive] Raymond Burkholder, and [Wayback/Archive] Falco Alexander for the above questions and answers.

From them, I learned that on a UAC elevated administrative command prompt, you can use these PowerShell for managing Memory Compression:

  1. Get-MMAgent shows the current Memory Compression state
  2. Disable-MMAgent -mc disables Memory Compression (requires a reboot)
  3. Enable-MMAgent -mc enables Memory Compression (requires a reboot)

Solved: trouble trying to create a new Microsoft Account looping back to the image/audio puzzle after solving it. Solution: use Firefox.

Posted by jpluimers on 2022/12/15

Message: "Please solve the puzzle so we know you're not a robot."I had trouble creating a Microsoft Account (so I could hand out on-line Office Licenses to users) where each time after solving the image or audio puzzle, it would shortly display a success, then loop back to the puzzle.

So I wrote a [Wayback/Archive] Thread by @jpluimers on Thread Reader App as I got stuck even before trying to add a Microsoft Account on any on m’y devices Windows 11 or Windows 10. It started with

[Wayback/Archive] Hi @MicrosoftHelps, I have a different problem. When creating an account using Edge on Windows 10 (latest version of both; no plugins; Microsoft Defender in default settings), solving the puzzle loops back to “Please solve the puzzle so we know you’re not a robot.”

The odd thing is that it did not work in either Edge or Chrome (both based on Chromium which uses the Blink browser engine) even in the anonymous/private browsing mode (InPrivate for Edge or Incognito Mode for Chrome).

Even Firefox had trouble, despite it being based on a totally different Gecko browser engine: after solving the puzzle it would continue but instead of displaying success, it showed an error page (the error page also occurred in the Firefox Private Browsing mode):

Task Manager themed dark on dark in Windows 11 version 22H2 is a known issue (thanks @jenmsft)

Posted by jpluimers on 2022/12/13

A known Windows Insider bug has entered the Windows 11 release: Task Manager will show wrong colours (on my stock Dell Windows 11 installs, see below, it will be dark on dark) under certain custom Windows colour settings (“Choose your mode” set to “Custom”).

Edit 20221214: it got fixed

OS Build 22621.963 [Wayback/A] KB5021255 fixed this on Patch Tuesday (which arrived on my machines later than my original publication), see [Wayback/Archive] December 13, 2022—KB5021255 (OS Build 22621.963) – Microsoft Support

Windows software glyph inputs: on-screen keyboard,

Posted by jpluimers on 2022/12/09

  • OSK.exe (on-screen keyboard) has been available for a very long time; it’s just a basic software keyboard (with optional numeric keypad)
  • Emoji input (Windows + . or Windows + ;)
  • Touch keyboard is part of the Notification Area (often called Icon Tray), has various layouts including a “handwriting recognition” one
    • It can be started automatically when you do not have a keyboard attached.

Note that Charmap.exe cannot select and copy Emoji, but it can do accented charcters.

Alternatively, you can install an international keyboard layout, but I have found out the hard way that fails in some combinations or remoting tools (sometimes including RDP).

More on this:

I tried starting the Touch Keyboard through other means (like tabtip.exe), but those failed on the Windows 10 machines I tried.

Windows 10 22H2 ISO download hashes

Posted by jpluimers on 2022/12/02

Since [Wayback/Archive] Download Windows 10 Disc Image (ISO File) hides this only to after you download, below is the complete list of Windows 10 22H2 ISO hashes.

For your convenience, Microsoft did not put it in alphabetic order (for instance, Dutch comes after Norwegian). For a few I downloaded I have added the ISO filenames (which for your convenience too is not included by Microsoft). Oh: note that “English” without any marker means “US English” (which has non-metric defaults, non-ISO page sizes, and odd date formats).

BTW: I wonder if there is a link for Windows 11 Disk Image (ISO File) as https://www.microsoft.com/en-us/software-download/windows11ISO gives a 404 error.
