Hauk

Hauk is a fully open source, self-hosted location sharing service. Install the backend code on a PHP-compatible web server, install the companion app on your phone, and you're good to go!

System Requirements

• Web server running PHP and Memcached or Redis.
• PHP memcached, memcache or redis extension installed on the web server.
• PHP ldap extension if using LDAP authentication.
• Android 6 or above to run the companion Android app.

Installation instructions

1. Clone or download this repository: git clone https://github.com/bilde2910/Hauk.git
2. Run sudo ./install.sh -c web_root where web_root is the folder you want to install Hauk in, for example /var/www/html. Follow the instructions given by the install script. Make sure to set a secure hashed password and edit your site's domain in the configuration file after installation.
3. Start the web server and make sure Memcached or Redis is running and properly configured and firewalled.
4. Install the companion Android app (from your favourite store linked above) on your phone and enter your server's settings.

Manual installation

If you prefer not to use the install script, you can instead choose to copy the files manually.

1. Clone or download this repository: git clone https://github.com/bilde2910/Hauk.git
2. Copy all files in the backend-php and frontend folders to a common folder in your web root, for example /var/www/html.
3. Modify include/config.php to your liking. Make sure to set a secure hashed password and edit your site's domain in this file.
4. Start the web server and make sure Memcached or Redis is running and properly configured and firewalled.
5. Install the companion Android app (from your favourite store linked above) on your phone and enter your server's settings.

Distribution-specific packages

The Hauk backend is available as packages for the following distributions:

Arch Linux

Install hauk-server from AUR. The backend will be installed to /usr/share/webapps/hauk-server.

Via Docker Compose

The official Docker image on Docker Hub is bilde2910/hauk. It comes with several different tags:

latest, stable-1.x and all releases from 1.5.2 and up are multi-arch and compiled for x86_64, armv7l and aarch64. 1.5.1 and older are x86_64 only. You can use any of these tags for all architectures, and Docker will automatically pick the correct one. If you need the image for a specific architecture, however, you can fetch them using *-amd64 (x86_64), *-arm32v7 (armv7l) or *-arm64v8 (aarch64) versions of any of the tags (e.g. latest-arm32v7).

docker-compose.yml

version: '3.4'

services:
  hauk:
    image: bilde2910/hauk
    container_name: hauk
    volumes:
      - ./config/hauk:/etc/hauk

Copy the config.php file to the ./config/hauk directory and customize it. Leave the memcached connection details as-is; memcached is included in the Docker image.

The Docker container exposes port 80. For security reasons, you should use a reverse proxy in front of Hauk that can handle TLS termination, and only expose Hauk via HTTPS. If you expose Hauk directly on port 80, or via a reverse proxy on port 80, anyone between the clients and server can intercept and read your location data.

Here's an example config for an nginx instance running in another container. You may want to customize this, especially the TLS settings and ciphers if you want compatibility with older devices.

server {
    listen 443 ssl;

    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers 'ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305';
    ssl_session_cache shared:SSL:10m;
    ssl_stapling on;
    ssl_stapling_verify on;

    ssl_ecdh_curve 'secp521r1:secp384r1';
    ssl_prefer_server_ciphers on;
    ssl_session_timeout 10m;
    ssl_session_tickets off;

    ssl_certificate /etc/letsencrypt/live/hauk.example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/hauk.example.com/privkey.pem;

    add_header Referrer-Policy same-origin always;

    add_header X-Content-Type-Options nosniff always;
    add_header X-XSS-Protection "1; mode=block" always;
    add_header X-Robots-Tag "noindex, nofollow" always;

    server_name hauk.example.com;

    location / {

}

Demo server

If you'd like to see what Hauk can do, download the app and insert connection details for the demo server:

Server: https://apps.varden.info/demo/hauk/
Password: demo

Location shares on the demo server is limited to 2 minutes and is only meant for demonstration purposes. Set up your own server to use Hauk to its full extent.

Translation status

Donate

Hauk is an ad-free, open source project, and I am not doing this for financial gain. Thus, my time spent making this is unpaid. I do however accept donations from anyone who appreciates my work enough that they feel inclined to compensate me, no matter the amount. Donations mean a lot to me, as they help cover costs associated with server upkeep, domains and hosting, and general cost of living, and they serve as an incentive for me to keep working on open-source projects.

If you wish to donate to me, you may check out my donations page on my website.
