Configure Domain_hint in asp.net core

This took me way to much time to figure out since there is a ton of old information on the internet. I wanted to change the default behavior when people are logging in to my ASP.NET Core website using Azure Active Directory (or Microsoft Identity Platform). After some searching I figured out how to change this setting. You have to add the following piece of code to the ConfigureService method in your Startup.

Switching to Google Fi

Last week I switched all the mobile lines of my family to Google Fi. We had t-mobile for some time but I wanted to try and see how Google Fi works. Since I am going to travel a bit for work, I was looking for a new phone which could work at least a working day without charging and gives me great coverage. I also wanted a plan with works great when abroad.

What to pack for business travel?

For my new job, I need to travel a lot again. So instead of giving tips on how to fold your underwear so you can travel 3 weeks with only carry-on, I will share some of the stuff I take with me during travel. Since I will be delivering presentations, demo’s and give training I travel with at least 2 laptops. In case 1 stops working, but also to have 1 ready to download stuff you might need to recover the other device in case you get a corrupt OS or something like that.

How to detect if your devices are trying to circumvent your pihole

As I described in my previous blog post, you can set up a pi.hole DNS server to optimize your network traffic and your browsing experience. But not every device will be respecting your DHCP DNS settings it seems. Some devices have hardcoded DNS entries and just ignore your settings. Scott Helme wrote on his blog how to redirect those naughty devices and redirect their traffic to your pihole instead. But before we start doing that I was curious to find how many of those devices I actually had on my network.

Installing pihole on your Cloudkey gen2+

The other day I bought myself a Gen2 cloudkey plus from Ubiquiti and replace my old cloudkey. It comes installed with the Unifi SDN and the new Unifi Protect. The device looks really nice and has a little display which shows you information about the applications running on the device. Since I have been playing with pi-hole lately on one of my Raspberry Pi’s, I was wondering if I could install pi-hole on the cloudkey so I would have everything from my network on a central place.

New job in the Azure Identity team

Adding FlightRadar24 feed to my FlightAware raspberry pi PiAware install

Since a week or so I am running PiAware from FlightAware on 1 of my Raspberries. It’s running fine. Thanks to Chris Johnson I also managed to feed Flightradar24 from the same feed. This are the steps I did on my raspberry through the shell. I don’t run a fancy container solution like Chris does on his setup so I had to steal some configuration and instructions from his github page.

Creating my config.gateway.json provisioning file for my USG

As described in a few previous blog posts I needed to set some configuration through the command line for my USG. But every time you provision the USG the changes will be lost. This can be solved to store the changes in the config.gateway.json file on my cloud key. Since the cloud key is running Ubuntu I can find that file in /usr/lib/unifi/data/sites/default (your site can be named differently, but mine is the default).

Configuring source address based routing on my Unifi USG

Updated 10/24/2018 since routing didn’t work anymore. You have to disable source-validation, thanks to Roelf for the comment with the correct command. For some time now I wanted to be able to test some network stuff. I want to be able to connect certain devices over a VPN to the Netherlands but without the need to configure every client with VPN connections. With this scenario it is possible to test different geo stuff accessing my network from different places in the world, it also helps me test the different latencies when going across the ocean and back.

Creating 2nd network with seperate IP range on my Unifi network

Some time ago I bought new network gear for my home from Ubiquiti. The Unifi range of hardware is very nice. It’s a bit pricy but you can do so much interesting stuff with it and the hardware is rock solid. At home I have the following hardware running: Unifi Security Gateway (USG) Cloud Key The 8 ports PoE switch to power access points and some security cameras Unifi 802.
