Drivers Causing "This file came from another computer and might be blocked to help protect this computer" On Startup

This weekend I had to reinstall a driver for a laptop touch pad. I went to the Sony site and got the driver, it came in a zip file and looked pretty standard. A load of driver files and an install file.




It install all OK and the touchpad started to have its scroll options, however then I rebooted and found each time the laptop started up Windows Vista kept asking to confirm I wanted to run the programs, "This file came from another computer and might be blocked to help protect this computer". Straight away I thought it had to be the file was blocked from running as it came from a download. I went to the files unblocked them all, clicked apply and rebooted again only to find it happen again.




Just to ensure I hadn't forgotten to click apply I tried this again only to find the same thing. After Googling for the issue I found the issue was that the installer had simply copied the drivers and files. This meant that the NTFS information was also copied, this information contained the flag "downloaded from internet" along with others.




The solution was to strip these files of this information, luckily you can obtain a free tool to do this. "Streams" from Sysinternals, I simply downloaded this,http://www.microsoft.com/technet/sysinternals/utilities/Streams.mspx, ran it on the directory, command prompt only, and rebooted to find all was well.


Certainly one to remember as I have came across this before and removed the program.

WebUSB - An unexpected update...

Image
In January at my new(ish) user group Momentum Meetups , I presented on "Reaching out beyond the Chrome" (although suffering from food poisoning so I was definitely going green at points!). It included  WebUSB and WebBluetooth . I was excited by how powerful it was and even had a colleague present something we had been prototyping in out work place. During the talk I mentioned security and how it had been designed so it only works on https and there's a permission model where you have to approve the device before it can be used. Unfortunately this week it came to light that Authentication devices could be bypassed via USB. These devices are a great way of proving you are who you say you are on the web beyond basic 2FA text's or applications. So being able to be able to bypass them via WebUSB is a big deal :( My Original Security Slide A few days later Google then disabled WebUSB by default effectively killing it off until such a time where its made secure...

Can you use BuildRoot with Windows Subsystem for Linux......

Image
A quick note I started this blog post back in August of 2018 and never completed it. Essentially I wrote most of it and then found I just couldn't run BuildRoot properly, I came back to it every Windows 10 release due to performance improvements etc however its only now with WSL2 that this is possible. Read on to find out the full story :) Original Post I love Windows Subsystem for Linux , I mention it all the time in work, done "brown bag" sessions on it, even did a lightning talk on it at DDDSW 18 . This week I've been working with a contractor to produce essentially an Embedded OS for a project. Previously I've always used existing distributions and made them "lite" or used preconfigured ones, Raspbian Lite for example however he promptly told me I'm doing it wrong and that I shoudl be using BuildRoot. Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. Sound's interest...

DotNet CLI , private NuGet feeds and Linux...

Today I hit an issue whilst trying to run dotnet run for some of our benchmarkdotnet tests which I like to run all new hardware I try out. My pair of Raspberry PI 4's arrived and I wanted to compare the performance of our Fingerprint capture code. I've hit the issue before and last time I figured it out I swore I'd blog and write it up as I knew I would forget! My benchmark project is a straight forward BenchmarkDotNet project however it consumers NuGet packages from both nuget.org as well as our private NuGet repository which requires authentication. For all of our windows machines this works without an issue for machines on the domain they authenticate seemlessly however when using Linux devices this is a different issue :( Instead on Linux devices we always get: /home/pi/dotnet/sdk/2.2.300/NuGet.targets(121,5): error :   GSSAPI operation failed with error - An invalid status code was supplied (SPNEGO cannot find mechanisms to negotiate). This essentially means it ...
