ungleich_hack_3

A micro project proposed as a solution for Hack 3: IPv6 cat from ungleich.

Overview

Per requirements, the project behaves differently depending on the version of the Internet Protocol used to navigate it:

• Via IPv4, it shows a static page saying "Sorry, only reachable by IPv6"
• Via IPv6, it shows a friendly cat picture

To determine which version is used, we examine the visitor’s IP address. This is done in a middleware that responds with an error page to non-IPv6 requests.

If the request goes through, a simple application can be accesses, with a single index view showing a friendly picture of a cat.

Usage

To install and run the project on your own computer, you must ensure that the following prerequisites are fulfilled:

• your operating system supports IPv6
• you can run Python version 3.6 or above (it is recommended to use a virtual environment), with:
  • pip
  • setuptools
• you can run the make command

Proceed to cloning this repository, and navigate to its directory.

Then, execute the following command to install the project’s required modules:

make install

Then, execute the following command to run the project using Django’s built-in web server:

make run

You can then navigate the project at http://localhost:8000/.

Deployment

To install and run the project in production, you must ensure that the following extra prerequisites are fulfilled:

• you can run an WSGI server with IPv6 support to expose the project’s application
• you can run a web server with IPv6 support to act as a file server for the project’s static files, and as a reverse proxy between the WSGI server and the internet

Proceed to deploying this repository, and navigate to its directory.

Then, execute the following command to install the project’s static files:

make build

Then, configure and run your WSGI server and your web server.
