How to enable FIDO U2F on Linux
STEP 1: Insert security key and cat /var/log/messages (or tail -f /var/log/messages and then insert security key)
Although some recent versions of Linux have built-in support for U2F security keys, many do not, and you may therefore have to make a minor system configuration change in order to allow the requesting web browser (such as Chrome) to communicate directly with your Key-ID U2F token via the USB port.
This is a system-wide configuration update that enables Key-ID U2F functionality on Linux for all users, and is entirely safe. It uses standard Linux udev rules, which allows you to identify and thus allow certain devices, based on their specific properties, such as its USB Vendor ID and Product ID.
The Feitian FIDO U2F token has a Vendor ID (VID) of 096e (hex) and a Product ID (PID) of 0854 (hex). To enable it on Linux, assuming you are running udev version 188 or later, simply create the file /etc/udev/rules.d/70-u2f.rules with the following contents:

Our Roadmap for QUIC and HTTP3 Support in NGINX
# Builds NGINX from the QUIC+HTTP/3 development branch
# - Based on the official NGINX docker image, including all modules built by default
# - OpenSSL replaced with LibreSSL to support QUIC's TLS requirements (statically linked)
#
# docker build --no-cache -t nginx:quic .
# docker run -d -p 443:443 -p 443:443/udp nginx:quic
#
# Note that a suitable configuration file and TLS certificates are required for testing!
# See <https://quic.nginx.org/readme.html> for more info

Add tailscale to an EdgeRouter and surviving system upgrade

Adding tailscale to an EdgeRouter (and surviving system upgrades)

I suggest you run sudo bash on all of these so you're the root user.

Installing

  1. Download tailscale and put the files in /config/. Find the latest stable or unstable version for your EdgeRouter's processor (ex. ER4 is mips and ERX is mipself)
sudo bash    # if you havent already

A script that fetches a ChromeOS image for ARM32 and extracts the Widevine and Flash binaries, saving them in a compressed archive for use with Chromium for DRM

The included script 'widevine-flash_armhf.sh' fetches a ChromeOS image for ARM and extracts the Widevine and Flash binaries, saving them in a compressed archive. Since it downloads a fairly large file (2Gb+ on disk after download) it is recommended that you run the script on a raspberry that has plenty of disk space.

The files in the compressed archive are copied to the folder /usr/lib/chromium-browser/ To run the file just type the following:

sudo ./widevine-flash_armhf.sh
