Rickrolling for 404 requests

Description

Every webserver log is spammed with 404 (Not Found) requests. The setup in this repository allows to redirect such requests to the famous Rickrolling Video.

Idea inspired by this Tweet.

Ansible

To ease configuration and deployment, Ansible is used and generates a configuration file. The input URLs (the 404) are listed in two files:

• redirect.txt: simple URLs, including the full request, no regexp required
• redirectmatch.txt: complex URLs, a regexp is required to match the URL

The “Redirect” and “RedirectMatch” names are based on the Apache2 mod_alias Module. It is not necessary to enable the more complex mod_rewrite module for simple redirects.

Apache2

In your vhosts configuration, all you have to do is include the rickrolling.conf:

Include "/etc/apache2/rickrolling.conf"

Data Source

Two different ways to load the data files into Ansible:

Local Copy

Check out this repository and point your Playbook to the redirect.txt and redirectmatch.txt files.

- name: Read block lists and set config
  set_fact:
    rickrolling_destination: "https://www.youtube.com/watch?v=dQw4w9WgXcQ"
    rickrolling_redirect: "{{ lookup('file', '/path/to/ansible-rickrolling/redirect.txt').splitlines() }}"
    rickrolling_redirectmatch: "{{ lookup('file', '/path/to/ansible-rickrolling/redirectmatch.txt').splitlines() }}"
- name: Install block list
  template:
    src: "/path/to/ansible-rickrolling/apache2.conf"
    dest: "/etc/apache2/rickrolling.conf"
    owner: www-data
    group: www-data
    mode: 0755
  notify:
    - restart apache2

Online Copy

Use the URI module to download a copy of the files during deployment.

Note: Your Ansible host must be able to reach GitHub during deployment.

- name: Fetch redirect.txt
  uri:
    url: https://raw.githubusercontent.com/andreasscherbaum/ansible-rickrolling/master/redirect.txt
    return_content: yes
  register: rickrolling_src_redirect
- name: Fetch redirect.txt
  uri:
    url: https://raw.githubusercontent.com/andreasscherbaum/ansible-rickrolling/master/redirectmatch.txt
    return_content: yes
  register: rickrolling_src_redirectmatch
- name: Import block lists and set config
  set_fact:
    rickrolling_destination: "https://www.youtube.com/watch?v=dQw4w9WgXcQ"
    rickrolling_redirect: "{{ rickrolling_src_redirect.content.splitlines() }}"
    rickrolling_redirectmatch: "{{ rickrolling_src_redirectmatch.content.splitlines() }}"
- name: Install block list
  template:
    src: "/path/to/ansible-rickrolling/apache2.conf"
    dest: "/etc/apache2/rickrolling.conf"
    owner: www-data
    group: www-data
    mode: 0755
  notify:
