Send instant message from server back to client using SignalR

UPDATED 28-08-2018: Added guidance to send message to specific client and not just for all + more screenshots on how _signalContextHub was added. This is a small blogpost explaining how to use SignalR for ASP Core 2.1 to send a message (or a signal :) ) from the server (controller action) back to the client view. Alot of posts explains how to make various bidirectional chats using SignalR to send messages from client to the server (from view to controller and back again), but the other way around (from server to client) is useful if you want to show progress bars [...]

ASP.NET Core 2.0 MVC: editing complex viewmodels with child models and dynamically retrieve properties from the model in the view or just a REALLY long title…

For the past couple of months I've been doing ASP.NET Core coding projects – building the backend and frontend of various websites for our customers. This has been a fun experience, but at times also very frustrating when things aren’t really working out. One thing is to follow examples and tutorials based on “perfect world” scenarios, another is to deal with real-world data and requirements. So this will be my first post in hopefully a series of ASP.NET Core posts to share some tips and tricks when things get a little more complicated. I assume you have some knowledge of [...]

Using Office 365 Portal Security Token for Authentication with custom website

When creating a lot of different web front-ends, it is always rather complex to get started with single sign-on or integrated login. The simple way to not maintain a credential database or passwords is to validate against a 3. party website. This is where the Office 365 Portal comes in handy, especially because many companies are already validating against or with it. I created this code as part of another solution, the example here has been cut down for demonstration purposes and easy integration. You will be able to validate against Portal.microsoftonline.com as long as the login is allowed for [...]

How to use SCCM SDK in C# with a WQL Query that contains joins

Sometimes you just stop and wonder: how DO you make a WQL query with joins and use it with the SCCM SDK in C#? It's that gnawing thought we all have right? So after spending an hour reading through people saying: "It's NOT supported!" and some people who said it was (without any examples whatsoever), I managed to get a small sample working. So if any of you should come across this challenge (which is of course the most of the world), then here is a code-example on how to do it: It's a small console application that output all [...]

Create and run scripts with the new feature “Run Powershell scripts from the ConfigMgr console” on current branch 1706

In my last post I talked about how we could activate the new feature "Run Powershell script from the ConfigMgr" on current branch 1706 and in this post I would like to talk about on how to get started using this wonderful feature once you have activated it. This feature really shows that the ConfigMgr product team over at Microsoft really listens to its community and that they do everything they can to improve the product. Tho this feature is a bit rough around the edges it shows great potential and i can't wait to see how it will evolve over time [...]

Remove non authorized members of the local administrator group with ConfigMgr

    MVP Jörgen Nilsson did a great post the other day over at https://4sysops.com/archives/monitoring-laps-with-configuration-manager/ where he showcased how one could monitor LAPS with the help of CI's in ConfigMgr to make sure it's installed and running properly. Continuing on the LAPS theme and ways ConfigMgr can help us improve security and maintain control I would like to talk a little about how we can remove non authorized members of the local administrator group with the help of Configuration Items/Baselines in ConfigMgr.   For those who are unfamiliar with LAPS (Local administrator password solution) you can learn more here: https://technet.microsoft.com/en-us/mt227395.aspx     [...]

FTP / SFTP monitor for SCOM

In this post we'll make a script for a FTP / SFTP monitor that can monitor the FTP/SFTP status, by doing the following operations: -Log in -Upload a file -Download a file -Delete the file Since Powershell doesn't have any built-in ftp support I was looking for some alternatives, and since I use WinSCP normally for ftp/sftp I found that they also support Powershell scripting, so why not take advantage of this? This guide was written with great help from WinSCP's own page: https://winscp.net/eng/docs/library_powershell Get the SSH fingerprint (This part is only nessary for the SFTP solution). Since we need the SSH [...]

Silent install Java 8 Update 71 and 72 with SCCM

In my last post about silent / unattended installation of Java 8 Update 66, we followed the new guidelines for how to install Java 8 silently by Oracle. The problem with that method is that it works when you try to run your script locally with administrator privileges it will work fine, but when you run the same script through SCCM / Configuration Manager, it will fail. And just to confuse you even more, it will only fail for the 32-bit version of java, not the 64-bit, even though you use the exact same method. This problem have been reported [...]

Upgrade System Center Configuration Manager Console with PowerShell

Since Service Pack 1 was released to SCCM 2012 R2 I have been upgraded several environments. A couple of customers wanted me to create a PowerShell script to uninstall existing ConfigMgr Console and install the new updated version with the latest cumulative updates and hotfixes. If you create a package to distribute it with SCCM make sure you point the Data source to the location of the Client installations files, Script, KB3084586-msp and kb3074857-msp. Installation command for the program will then be: PowerShell.exe -file "script.ps1". Remember to set PowerShell execution policy to "Bypass" under Client Settings. This will not affect [...]
