They say there is a first time for everything. For me, it’s how to download and upload files to Azure Blog Storage using Connection String. Recently I was given Connection String, Container name and had to download some files from Azur Blog Storage. After some research and trying Connect-AzAccount, I found that the proper way to go is thru New-AzStorageContext.
When I created ImagePlayground, I thought about how to show its usefulness to the general community. On how to deliver what PowerShell can do. Then I saw on some forum people asking BGInfo to expand and allow running PowerShell scripts so that the data on the BGInfo Wallpaper can be gathered from PowerShell rather than VBS. I thought this was a great idea to create BGInfo using PowerShell without the necessity of using BGInfo at all.
ImagePlayground is a PowerShell module that works in PowerShell 5.1 and PowerShell 7+. It works partially on Linux and should work on macOS, except for charts. That means it’s partially cross-platform, but the end goal is to make it work fully on all platforms. So what can this module do?
PSTeams is a PowerShell module that helps simplify sending notifications to Microsoft Teams via Incoming webhooks. It’s easy to use and doesn’t require playing with JSON. Since version 2.0, it started to support Adaptive Cards; in version 2.1, I’ve added the ability to mention people. Today I’m introducing an easy way to send data as a table and a quick way to add a line break.
Virus Total is an excellent service. It’s a single place where hundreds of antivirus engines can verify if the file, URL, domain name, or IP Address is trusted or not. Of course, it’s not a silver bullet, but it brings tremendous value, and I often verify files I download before executing. Since I release a lot of new or updated PowerShell modules on a weekly/monthly basis, I thought it would be great to send newly released versions straight to Virus Total so I can have them checked before anyone executes them. I also hope to prevent false positives from some antivirus vendors that may tag my modules as malware because they haven’t seen the DLL or PowerShell module in this form before. I’ve seen it happen to DBATools, so why not try and push my modules before users even use them?
I work a lot with Active Directory-related tasks. One of the tasks is to know the group membership of critical Active Directory Groups such as Domain Admins, Enterprise Admins, Schema Admins, Event Log Readers, and a few others that are a bit less known. As I did it, I got bored of typing the group names repeatedly and decided that enough was enough and there must be an easier way for me to do that.
In my earlier blog post, I showed you a way to find duplicate DNS entries using PowerShell, but the focus was on finding duplicate entries based on hostname. But what if you would like to find duplicate entries based on IP Addresses? This was the question I was asked on Reddit, and I thought it was a legitimate request, so today’s focus will be on transposing table output from earlier functions to present data differently.
Today’s blog post is about Active Directory-integrated DNS and how to find duplicate entries. By duplicate, I mean those where one DNS name matches multiple IP addresses. While some duplicate DNS entries are expected, in other cases, it may lead to problems. For example, having a static IP assigned to a hostname that later on is also updated with dynamic entries.
Today I was reading Twitter, as I am pretty addicted to technology news when Adam Bacon mentioned that he’s surprised that no one has rebuilt IIS Parser as pure PowerShell. While this is not entirely true, and some modules can do some parsing, I decided to try my luck. While doing it from scratch in PowerShell is possible, I opted to use an external C# library that does all the heavy lifting and is optimized for speed.
