NET::ERR_CERT_AUTHORITY_INVALID and you are webmaster?

 I am webmaster for https://linuxintro.org. However, when I visited this page in Chrome I always got the message


NET::ERR_CERT_AUTHORITY_INVALID


Today I resolved it after some years. I went to https://letsencrypt.org/getting-started/ followed the instructions and got it working in 11 minutes. And it did not cost anything :)

I am super happy this site exists and makes it so easy for me. I immediately donated to them because they are just so useful :)

My SAT>IP Server

Image
I bought a SAT>IP Server to bring my satellite TV into my WLAN. I want this because my satellite's connection is in another place in the room than my TV. First learning: You need a SAT>IP Server, not a SAT>IP Receiver. A SAT>IP Server receives signals from the LNB. A SAT>IP Receiver receives a connection from the SAT>IP Server and transforms it into an HDMI stream (for example). As SAT>IP Receiver you can also use the VLC software which will just display the video stream. When buying, make sure you buy a server. Second learning: The latest Kathrein EXIP 418  SAT>IP Server did not work with my setup. It needs a multi-switch between the LNB and the server. When buying, make sure you understand the setup. Mine looks like this: So I settled for a Telestar  TwinBit SAT>IP Server. Laptop To watch TV on my Windows Laptop, I download VLC and start it. Click View->Playlist. Point it to Universal Plug'n'Play, and wait 6 minutes, 47 seconds, and the ser...

Network Engineer Certification

Image
I prepare for being certified as Network Engineer. This means you have to digest a lot of complicated topics... or you make it fun by using analogies. I bet I will teach you BGP , Interconnects and VPN in the next 10 minutes so that you won't forget it or you get your money back. Let's start like this: Imagine the internet is the highway network connecting towns (datacenters). Then, the cars are network packets driving over it. If highways are the internet, network packets are cars The cars deliver pizza. There are routes where you can drive fast and there are slow routes. Some have four lanes, others are just narrow alleys. That's latency and bandwidth aka throughput . Now I tell you, if I want a pizza, I want it in 10 minutes. Having 5 pizzas after 50 minutes just isn't the same experience although throughput would be the same.  Next time you wait for a pizza - think of this blog and agree: nothing beats latency ;) Do you know Lombard street? That's the curviest...
