pfSense HAProxy HTTPS HTTP Problem Accessing From LAN

June 30, 2022 by Jack Zimmermann 7 Comments

After installing my new pfSense firewall, I wanted to expose some of my servers to the internet. First, I had HTTP and HTTPS made available for this blog by using NAT. But that’s not very secure, so I found HAProxy, a module inside pfSense. It’s a reverse proxy, among other things.
I configured it to use ACME, another module inside pfSense, to acquire SSL certificates from Let’s Encrypt, handle all SSL traffic and then send the requests to my internal servers. The internal servers no longer need to handle SSL traffic, so they talk to the HAProxy with unencrypted port 80 traffic. Thus separating the outside WAN from my servers on the inside LAN. I found an excellent guide on how to set this up.

Atom Editor Platformio Hangs at startup endless restart – fixed

July 25, 2020 by Jack Zimmermann Leave a Comment

When installing the excellent Atom Editor with Platformio-ide, the main window inside the editor would hang on my new Mac. I uninstalled the program and deleted the .atom directory and tried to reinstall, the application would freeze the main window, and I had to force-quit the program. After a lot of experiments, I finally found a way to fix the problem.

Hackintosh AMD Shutdown Problem with Fenvi FV-T919

May 28, 2020 by Jack Zimmermann 1 Comment

After finally building my first Hackintosh, I decided that the AMD Ryzen™ 3900X processor would be perfect, although Apple never made a Machintosh machine with an AMD processor. I used the Gigabyte X570 Aorus Elite motherboard because it has everything I need for my build. But I decided to upgrade my working machine with a Bluetooth/Wifi PCI-E card to be able to use the SideCar function in macOS. Being able to connect Bluetooth equipment is also lovely.

After Googling around, I found a card that filled all my needs. It’s the Fenvi FV-T919, a Bluetooth 4.0, and 802.11 a/b/g/n/AC compatible Wifi-card that uses ICs that are supported in macOS directly, so no patching needed.

But after installing the card, there was a problem when trying to shut down the machine from the macOS side; the computer would shut down and immediately start up again. Fortunately, I’ve found a fix for the problem.

When building my AMD Hackintosh, I decided to prepare for a future upgrade of my CPU. I based my current build on an AMD Ryzen 3900X, but I plan to update it to a Ryzen 3950X. So I decided to install a CPU water cooling system.

Quartus Prime FPGA USB-Blaster Problems On Ubuntu 18.04

January 12, 2020 by Jack Zimmermann 5 Comments

I’ve decided to learn how to program FPGA:s. So I got myself two Terasic boards, one Terasic DE10-Nano for testing out the excellent MiSTer FPGA hardware arcade/computer/console emulator and a simpler DE0-Nano for beginning to learn Verilog.

But the software used, called Intel Quartus Prime 19.1, is truly horrible. The Windows version doesn’t work with high-resolution screens when using scaling; the text is cut off on the display. So I installed it on my Linux Ubuntu 18.04 machine instead. Now the display works, but there’s a lot of other problems, like getting the dreaded error message: “USB-Blaster unable to scan device chain”. I’ve written them down here for later reference, and maybe you have the same install problems, so this might help.
