The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare [email protected]:usi-systems/easytrace.git

GeoIP Block NGINX Ubuntu 20.04

Block or filter IPs based on location in Nginx (tested on 1.18.0) on Ubuntu 20.04.

Install Nginx modules

To make use of the geographical filtering, we must first install the Nginx GeoIP module as well as the GeoIP database containing the mappings between visitors’ IP addresses and their respective countries. To do so, let’s execute:

$ sudo apt install libnginx-mod-http-geoip geoip-database

Command Execution

exec           - Returns last line of commands output
passthru       - Passes commands output directly to the browser
system         - Passes commands output directly to the browser and returns last line
shell_exec     - Returns commands output
\`\` (backticks) - Same as shell_exec()
popen          - Opens read or write pipe to process of a command
proc_open      - Similar to popen() but greater degree of control
pcntl_exec - Executes a program

srsLTE notes

These are notes I've taken while rying to get srslte up and running. This is messy, sorry...

Working solution - LimeSDR + SoapySDR + srsLTE

This is my personal list of functions that I wrote for converting `mov` files to `mp4`!

	# NGiNX reverse proxy configuration for Jellyfin
	#
	# Use this configuration on NGiNX running on the same server as your Jellyfin instance. Replace the values as needed.
	# LetsEncrypt is enabled and configured using `certbot`: install it via apt on Debian (`sudo apt install certbot`) or
	# your package manager of choice. To start, make only the first section (port 80) active, then once that configuration
	# is active, run Certbot for the first time to request your cert. Then, add the second section (port 443) and reload.
	# With this config left in place, Certbot's automatic renewal will work and automatically replace the cert and
	# reload NGiNX as needed, without interrupting your Jellyfin instance.
