Windows Defender Firewall Inbound Rule for ICMPv6

Hi!

I'm getting more into IPv6 these days and found that ICMP is very important for IPv6 connectivity.

Windows Defender Firewall with Advanced Security (on Windows 10 at least) comes with some inbound ICMPv6 allow rules, but unfortunately they don't allow for quite enough.

I went ahead to create a rule by hand, but found out that you cannot set a group for the rule through the GUI, so instead I opted for creating a little PowerShell command.

You have to run it from a UAC-elevated PowerShell instance.

This rule is based on the existing default ICMPv6 rules.

Create the rule:

New-NetFirewallRule -DisplayName "Core Networking - CUSTOM - Allow Incoming ICMPv6" -Group "Core Networking" -Direction Inbound -Action Allow -Protocol ICMPv6 -Program System

Remove the rule again:

Remove-NetFirewallRule -DisplayName "Core Networking - CUSTOM - Allow Incoming ICMPv6"

Some people may want to exclude echo request for privacy or "security (through obscurity)" reasons, but I don't think it's that big of a deal.

Of course feel free to customize the command in general. The official documentation page (docs.microsoft.com) is very informative.

If you have any other firewalls between you and the sender, you may have to check their rules as well.

I tested the rules with a website like ipv6-test.com.

(Re)Setting Hyper-V Virtual Machine Client Zoom Level

Hi!

A couple of days ago I was playing around with Hyper-V virtual machines. At some point I set the "View" => "Zoom Level" to 25%.

Unfortunately, at 25% the window becomes so small that you cannot see the View menu in the menu bar any more because it gets cut off. And for some reason you cannot use the arrow keys on the keyboard to navigate the menus either.

This zoom level not only applies for a single virtual machine, but all of them, as it as a general Hyper-V client setting.

Trying to access the menu when the VM is shut down does not work because the "Zoom Level" submenu is disabled, and once the VM is booted up, the window resizes instantly.

The only reliable way to (re)set it appears to be editing the Hyper-V client configuration on the host file system:

  1. Close the Hyper-V client window (the one that opens when you connect to / double-click a VM)
  2. Open the file at %UserProfile%\AppData\Roaming\Microsoft\Windows\Hyper-V\Client\1.0\vmconnect.config and set the setting with ZoomLevel back to 100 (or something similarly usable):
    <?xml version="1.0" encoding="utf-8"?>
     <configuration>
         <Microsoft.Virtualization.Client.InteractiveSession.InteractiveSessionConfigurationOptions>
             <setting name="ZoomLevel" type="System.UInt32">
                 <value>100</value>
             </setting>
             [...]
         </Microsoft.Virtualization.Client.InteractiveSession.InteractiveSessionConfigurationOptions>
     </configuration>
  3. Save and close the file
  4. Connect to / double-click a VM again

I hope this was helpful to you.

Disable Autoplay For Videos in Firefox 63

Hi!

Just after updating to Mozilla Firefox 63 (on Windows), I found that my setting to disable autoplaying media / videos was no longer effective - at least for HTML5 videos.

Apparently one of the changes for this release was to include an autoplay video blocker, but I could not find anything definitive about this in the settings.

I decided to disable autoplay for all videos (which is my preferred setting anyway) once again by doing the following:

  1. Open the config editor by entering about:config in the navigation bar.
  2. Enter the "autoplay" as a filter.
  3. Find the entry "media.autoplay.default", double-click it and set it to "1" to disable media autoplay browser-wide.

I just left the old setting "media.autoplay.enabled" as "false", even though it does not seem to be relevant any more.

After reloading the website with the video (in this case YouTube), once more it showed the play icon on top of the video instead automatically starting playback.

Using Git Bash With Custom Installation Of GPG / GnuPG

Hi!

You have probably noticed that Git for Windows comes with MinGW64, which enables you to use programs (or to be more precise: Windows versions of these programs) that are usually only available to Linux users. One of the programs that MinGW64 / Git for Windows ships with is GPG / GnuPG. The current version of Git for Windows (2.17.1) for example comes with GPG version 1.4.22.

If you prefer using a custom installation of GPG / GnuPG by default, which is probably much more current than the one you installed manually (2.x), you can achieve this by doing the following:

  1. Install GPG as you normally would
  2. Make sure it is executable in the command line / PowerShell (as in: make sure the bin/ subdirectory of the GPG program directory is included in the PATH environment variable)
  3. Go to the Git for Windows program directory (e.g. C:\Program Files\Git\)
  4. Navigate to the usr/bin/ subdirectory and rename gpg.exe to something else (like gpg_disabled.exe)
  5. Close any open Git Bash instances and start a fresh one
  6. Check the GPG version via 
    gpg --version

The way that Git Bash works is that is has its own set of directories which have a higher priority when looking for executable files than the ones in Windows' PATH environment variable. So in order to have your own GPG executable working as the "gpg" command, you have to get the included gpg.exe out of the way so it keeps looking in Windows' PATH environment variable.

You can still access the old GPG executable by using the new name (e.g. "gpg_disabled").

Unfortunately you have to do these steps every time you install or update Git for Windows, but at least now you know where to look!

The upside is that now Git (executed from the Git Bash) also uses your own version of GPG for its GPG-related operations.

I hope this was helpful.

High DPI / Font Scaling Display Problem With LibreOffice

Hello!

When I installed LibreOffice on my Windows 10 notebook with 125% font scaling, I immediately noticed that the menu bar was somehow hiding behind the title bar and everything I clicked was recognized as clicked a couple dozen pixels above what I was actually pointing at.

This seems to be a known problem for LibreOffice with OpenGL and high DPI / high font scaling, maybe specifically in conjunction with my Intel HD Graphics / IGPU.

The fix is fairly easy but difficult to find out on your own:

  1. Make sure that no LibreOffice application is running.
  2. Open the LibreOffice OpenGL blacklist configuration file with a text editor, usually found at C:\Program Files\LibreOffice 5\share\opengl\opengl_blacklist_windows.xml.
  3. Inside the block enclosed by the <blacklist> tag, add the following block: 
    <entry os="all" vendor="intel">
    <device id="all"/>
</entry>
  4. Save and start a LibreOffice application to check.

This should do it!

Thanks for reading!

Using Windows Photo Viewer in Windows 10

Hi!

If your Windows 10 system is an upgrade from a previous Windows version, you will not have encountered this problem.

This is only relevant for clean, non-upgrade Windows 10 installs.

I noticed that on my clean Windows 10 install the default application for viewing picture files like JPEG or PNG was the Microsoft Photos app. As I prefer the classic Windows Photo Viewer application for viewing images, I tried to select that as the default. Surprisingly enough, it was not in the list of options.

To add the Windows Photo Viewer back to the list of applications for pictures, you have to import missing registry entries. This is due to the fact that Windows Photo Viewer does not come as an executable but as a DLL.

The following explains the process for the whole system (not just the current user). The source article contains an alternative method for just the current user as well as a "sort order fix" solution that takes into account the order in which the files were sorted inside the directory.

  1. Download the "Restore_Windows_Photo_Viewer_ALL_USERS.reg" file from the source article or create a new text file with a ".reg" extension and the following contents: 
    Windows Registry Editor Version 5.00

  2. If you created the file by hand, it should use Windows line endings (CRLF).
    Also, the original file has UCS-2 LE BOM encoding, but I am not positive if that makes any difference as opposed to standard UTF-8 encoding without a BOM. I checked this with Notepad++.
  3. Run the .reg file.
  4. This should be it! You can now delete the .reg file and try selecting Windows Photo Viewer once again.

I think it is a bit weird that Microsoft would choose to omit these settings for a clean Windows 10 install, but I am happy that I can still use it with just this little tweak.

PhonerLite With FRITZ!Box

Hello!

If you want to set up your PhonerLite VoIP/SIP client with the FRITZ!Box so you can receive phone calls on your computer as well, of course you should have a look at the official AVM documentation (like the one for the FRITZ!Box 7390).

However, I encountered the following problems:

  • outgoing calls would result in a "480 Temporarily Unavailable" error (even the test number **797)
  • saving the configuration (tab "Configuration" => "Save" button) repeatedly would cause the status bar to alternate between
    • showing a red indicator and the error message "sip:<number>@fritz.box not registered <Connectivity Checks Failed>" every second click
    • showing a green indicator and the message "sip:<number>@fritz.box registered" every other click

I changed the following server / connection settings to fix the problem:

  • Proxy/Registrar: <FRITZ!Box IP address instead of fritz.box, e.g. 192.168.1.1>
  • Domain/Realm: fritz.box

After that, every time I saved the configuration if would show the success indicator and message and telephony just worked in general.

My local network interface uses an external DNS server for hostname resolution and I have added the fritz.box name manually in my hosts file. This might be why this was causing me problems.

I hope this was of any help to you in case you encountered this as well.

Thanks for reading!

Using msysgit With PuTTY Pageant & Plink

Hi!

If you have installed msysgit and are planning on using it in combination with Pageant from the PuTTY tool suite, you might run into the problem that it does not attempt to use any of the keys you have already loaded into Pageant. You can fix this by telling msysgit which program to use for the git fetch and pull operations:

  • Open your System window (Windows + Pause or "Start" => Right-click on "Computer" => "Properties")
  • Click on "Advanced system settings" (on the left)
  • Click on "Environment Variables..." (on the bottom)
  • Add a new system variable (or user variable if you just want this setting for the current user): "New..."
  • Variable name: GIT_SSH
    Variable value: (path to plink.exe) for example: C:\Program Files (x86)\PuTTY\plink.exe (important: just the path, no quotation marks at the beginning or the end!)
  • If you haven't already on this system / user, connect to the server via PuTTY in order to get the SSH server fingerprint prompt and remember it
  • Close any existing Git Bash / msysgit instances and start it up again

This should do it!

I hope this was helpful.

Thanks for reading!

Mozilla Thunderbird: Changing the EHLO / HELO Value in the “Received”-Header for Outgoing Mail

Hi!

If you have had a look at your outgoing e-mail headers that you've sent from Mozilla Thunderbird, you might have noticed that Thunderbird uses the IP of the network interface that it uses to connect to the internet with by default. If you are using a router on your network, this is a private IP from your LAN (for example 192.168.1.2) instead of one that might be of actual use.

Example:

Received: from external.sender.host.example.org ([123.123.123.123] helo=[192.168.1.2]) by
 mail.example2.org (incoming-mta-service) with esmtpsa (outgoing-mta-service) id
 0a1b2c-3D4e5F6G7h-0a1B2c for <[email protected]>; Sun, 02 Nov 2014 20:55:41 +0100

where "123.123.123.123" is the publicly facing IP and "external.sender.host.example.org" is its hostname.

If you do not wish to expose this information to every and all recipients of the e-mails you are sending with Thunderbird to (maybe out of security concerns in a business environment), you can set the EHLO / HELO value manually for every outgoing e-mail sent by the Thunderbird client with your current user profile and even for every simple SMTP server individually.

Here's how:

Globally

  • Open your Thunderbird options ("Tools" => "Options")
  • "Advanced" => "Config Editor..."
  • Create (or edit) the entry named "mail.smtpserver.default.hello_argument". If you need to create it, use right-click => "New" => "String".
  • Change the value to the desired IP or hostname (FQDN).

Per SMTP server

  • Open your Thunderbird options ("Tools" => "Options")
  • "Advanced" => "Config Editor..."
  • Create (or edit) the entry named "mail.smtpserver.smtp<number>.hello_argument" where <number> is the ID for the SMTP server you would like to apply the setting to. Type "mail.smtpserver.smtp" to see which ones are available and which ID they have. If you need to create the entry, use right-click => "New" => "String".
  • Change the value to the desired IP or hostname (FQDN).

Technically this value is not relevant for sending/receiving the mail, but because it might be used for spam scoring or simply out of courtesy I would recommend entering a valid IP / hostname.

I myself am using 127.0.0.1.

Thanks for reading!

Deleting Huge Directories in Windows Via Command Prompt

Hi!

If you'd like to delete a huge folder / directory in Windows with maybe thousands or hundreds of thousands of files inside, doing that via Explorer might cost you a lot more time than via command prompt.

Here's how to do it faster:

  1. Open the command prompt by using "Start" => "cmd" and navigating to the desired path via "cd <path>" or "pushd <path>"
    - OR -
    navigate to the folder in the Explorer and use Shift + right-click and "Open command window here"
    (Note: if deleting the desired folder requires elevated privileges, you will have to start a command prompt in elevated mode and navigate the old-fashioned way)
  2. Use the following command: 
    rmdir /s /q folder

A little explanation about rmdir's flags:

  • /s: removes the directory itself including all the contained files and subdirectories
  • /q: forces deletion and does not ask for approval

Doing this can be very helpful in a coding environment where you can easily end up with thousands of small files.

Thanks for reading!
