Windows: What ports does application/program X have open?

November 25, 2023
Leave a Comment

I recently had to help somebody with a Windows 10 based application which offered a “connection” facility (i.e. enter your computer’s IP address and port and the 3rd party system would connect to it), but the application failed to say which port(s) it had open.

Whilst there are a number of ways to view open ports – such as Microsoft’s Sysinternal’s TCPView and NirSoft’s CurrPorts – I wanted to suggest a way which neither required an additional piece of software to be installed and didn’t require administrator access.

Here are the steps to find out what ports application “AppName” has open:

Getting Mailvelope working on Brave Browser

For the last few years, I’ve been using Brave as my primary web browser due to its advert and tracking blocking abilities – extremely useful on YouTube! It’s based on Chromium (like Google Chrome and Microsoft Edge), but more privacy/anti-ad orientated.

I’ve also been wanting to GPG/PGP sign some emails using my web based email clients so I’ve installed the Mailvelope plugin from the Google Chrome store and in conjunction with GPG4Win it means I should have access to all the PGP and GPG keys stored on my Windows 10 machine… Except it doesn’t work – it fails to list any installed keys… Why?

Well, it all comes down to a Chrome based protocol called NativeMessaging which requires software (such as GPG4Win) to registered their “acknowledgement” of browser plugins such as Mailvelope by adding (in the case of Windows) various registry settings for the browser to read and interlink.

In the case of Brave, it appears the others of GPG4Win aren’t (currently) aware of it and so don’t set the various registry settings for it to work correctly – and Brave, unlike Microsoft Edge, has no “fall back” facilities to check other browsers for their Native messaging setup. I have reported this to both the Brave Community and to GnuPG (the maintainers of GPG4Win) on their bug tracker – including suggested fixes for both organisations, but it may be some time before this is fixed. So what can you do in the meantime?

Easiest way:

If trust running random commands on your computer, run the following two commands in an escalated permissions (“Run as Administrator”) Windows Command Prompt to copy the existing settings from Chrome over:

REG COPY "HKCU\Software\Google\Chrome\NativeMessagingHosts\gpgmejson" "HKCU\Software\BraveSoftware\Brave-Browser\NativeMessagingHosts\gpgmejson" /s
REG COPY "HKLM\Software\Google\Chrome\NativeMessagingHosts\gpgmejson" "HKLM\Software\BraveSoftware\Brave-Browser\NativeMessagingHosts\gpgmejson" /s

Restart Brave and all should be working.

Manual way

Add/Set the following registry key:

Path: HKEY_CURRENT_USER\Software\BraveSoftware\Brave-Browser\NativeMessagingHosts\gpgmejson
Type: Reg_SZ
Data: C:\Program Files (x86)\Gpg4win\bin\gpgme-chrome.json

(updating the “Data” path to where you’ve installed Gpg4Win as appropriate)

Restart Brave and all should be working.

iPhone Windows 10 Microsoft Store Firmware location

I’ve just been trying to recover an old iPhone 5s which is stuck in recovery (DFU) mode and whilst I haven’t yet had any luck getting beyond the Apple logo yet, I hope the following information may help others.

I installed iTunes 12.10.7.3 on my Windows 10 Professional machine using the Microsoft Store (which now appears to be the preferred way Apple is distributing it) and I connected it up, it saw the iPhone and downloaded the 2.9Gb firmware. I did then try a few other applications to try and fix the Apple iPhone but they needed the firmware – but where was it on my machine?

A few sites suggested checking C:\Users\<Username>\AppData\Roaming\Apple Computer\iTunes – but that path was empty for me. However, using Windows 10’s resource monitor, I soon spotted the firmware file was at C:\Users\<Username>\AppData\Local\Packages\AppleInc.iTunes_nzyj5cx40ttqa\LocalCache\Roaming\Apple Computer\iTunes\iPhone Software Updates\iPhone_4.0_64bit_12.4.7_16G192_Restore.ipsw

I suspect the name of the “Package” may differ between iTunes versions, but that should help guide you to the iPhone IPSW firmware file (which I could have also downloaded from http://updates-http.cdn-apple.com/2020SpringFCS/fullrestores/061-94832/B6D93224-1059-4DF0-9438-78CD3BED57FE/iPhone_4.0_64bit_12.4.7_16G192_Restore.ipsw – but “guessing” that URL might have been tricky).
