About

As the name suggests Heimdall Application Dashboard is a dashboard for all your web applications. It doesn't need to be limited to applications though, you can add links to anything you like.

Heimdall is an elegant solution to organise all your web applications. It’s dedicated to this purpose so you won’t lose your links in a sea of bookmarks.

Why not use it as your browser start page? It even has the ability to include a search bar using either Google, Bing or DuckDuckGo.

Supported applications

You can use the app to link to any site or application, but Foundation apps will auto fill in the icon for the app and supply a default color for the tile. In addition, Enhanced apps allow you provide details to an apps API, allowing you to view live stats directly on the dashboard. For example, the NZBGet and Sabnzbd Enhanced apps will display the queue size, and download speed while something is downloading.

Supported applications are recognized by the title of the application as entered in the title field when adding an application. For example, to add a link to pfSense, begin by typing "p" in the title field and then select "pfSense" from the list of supported applications.

Installing

Apart from the Laravel 11 dependencies, namely PHP >= 8.4, Ctype PHP Extension, cURL PHP Extension, DOM PHP Extension, Fileinfo PHP Extension, Filter PHP Extension, Hash PHP Extension, Mbstring PHP Extension, OpenSSL PHP Extension, PCRE PHP Extension, PDO PHP Extension, Session PHP Extension, Tokenizer PHP Extension, XML PHP Extension, the only other thing Heimdall needs is sqlite support and zip support (php-zip).

If you find you can't change the background make sure php_fileinfo is enabled in your php.ini. I believe php_fileinfo should be enabled by default, but one user came across the issue on a windows system.

Installation is as simple as cloning the repository somewhere, or downloading and extracting the zip/tar and pointing your httpd document root to the /public folder then creating the .env file and generating an encryption key (this is all taken care of for you with the docker).

cd /path/to/heimdall
cp .env.example .env
php artisan key:generate

For simple testing you could just go to the folder and type php artisan serve

There is also a multi-arch Docker which supports x86-64, armhf and arm64, instructions on how to use them at

Updating

To update your instance, simply clone this repository or download the zip/tar file with the new version and copy it over the old installation.

Search Providers

v2.3.0 added the ability for users to customise the search options.

Options are stored in /storage/app/searchproviders.yaml (/config/www/searchproviders.yaml on docker installs), feel free to rearrange the options, add new ones, delete ones you don't use, etc.

Consider contributing to https://github.com/linuxserver/Heimdall/discussions/categories/search-providers to help others add new ones.

The item at the top of the list Tiles allows you to search for apps on your dashboard by name, this can be helpful when you have lots of icons.

New background image not being set

If you are using the docker image or a default php install you may find images over 2MB won't get set as the background image, you just need to change the upload_max_filesize in the php.ini.

If you are using the linuxserver.io docker image simply edit /path/to/config/php/php-local.ini and add upload_max_filesize = 30M to the end.

Docker and enhanced apps

If you are running the docker and the EnhancedApps you are using are also in dockers, you may need to use the docker networking addresses to communicate with them.

You can do this by using http(s)://docker_name:port in the config section. Instead of the name you can use the internal docker ip, this usually starts with 172.

Languages

The app has been translated into several languages; however, the quality of the translations could benefit from some work. If you would like to improve them, or help with other translations, they are stored in /resources/lang/.

To create a new language translation, make a new folder with the ISO 3166-1 alpha-2 code as the name, copy app.php from /resources/lang/en/app.php into your new folder and replace the English strings.

When you are finished, create a pull request.

Web Server Configuration

Apache

A .htaccess file ships with the app, however, a lot of apache installations disallow .htaccess files by default. You will notice this due to some links not working like /settings. In addition mod-rewrite needs to be enabled if it isn't already.

Fixes & work around options

- Apache global allow .htaccess

Find the AllowOverride None line in your apache configuration and change this to AllowOverride All

- Apache vhost configuration allow .htaccess

In the apache vhost configuration in the <Directory /> block add AllowOverride All

- Add .htaccess content in apache configuration

You can add the full .htaccess into your apache configuration, this way you do not need to allow .htaccess files. You can even shorten the content of the .htaccess when inserting it into the apache configuration to:

Options +FollowSymLinks
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]

More info

More info about AllowOverride can be found here: https://httpd.apache.org/docs/2.4/mod/core.html#allowoverride

Nginx

If you are using Nginx, the following directive in your site configuration will direct all requests to the index.php front controller:

location / {
    try_files $uri $uri/ /index.php?$query_string;
}

Someone was using the same Nginx setup to both run this and reverse proxy Plex. Plex is served from /web so their location was interfering with the /webfonts.

Therefore, if your fonts aren't showing because you have a location for /web, add the following:

location /webfonts {
    try_files $uri $uri/;
}

If there are any other locations that might interfere with any of the folders in the /public folder, you might have to do the same for those as well, however it's a super fringe case.

Reverse proxy

If you'd like to reverse proxy this app, we recommend using our letsencrypt/nginx docker image: SWAG - Secure Web Application Gateway You can either reverse proxy from the root location, or from a subdomain (subfolder method is currently not supported). For HTTPS proxy, make sure you use the HTTPS port of Heimdall webserver, otherwise some links may break. You can add security through .htpasswd

location / {
    auth_basic "Restricted";
    auth_basic_user_file /config/nginx/.htpasswd;
    include /config/nginx/proxy.conf;
    proxy_set_header X-Forwarded-Proto https;
    proxy_pass http://heimdall;
}

Self-signed certificates and local CAs

Per default Heimdall uses the standard certificate bundle file (ca-certificates.crt) to verify HTTPS sites and will ignore additional certificates placed in /etc/ssl/certs. If you wish to use enhanced apps with HTTPS sites that use a self-signed certificate or certs signed with your own local CA, you can override the default bundle:

• Create a unified certificate .pem file that contains all CAs and certificates that Heimdall has to verify. For example, if you use both LetsEncrypt and a local CA for your internal apps, concatenate the LetsEncrypt intermediate CA (export via browser) and your local CA cert.pem (or any number of self-signed certs) into one heimdall.pem file.
• Place the heimdall.pem into the container (if you use Docker), for example by placing it in the path that you mapped to /config. Make sure that the Heimdall user has read access (chmod a+r).
• Set the openssl.cafile setting in /config/php/php-local.ini to your cert bundle:

# /config/php/php-local.ini
openssl.cafile = /config/heimdall.pem

Restart the container and the Enhanced apps should now be able to access your local HTTP websites. This configuration will survive updating or recreating the Heimdall container.

Allow Internal IP Requests

By default, Heimdall blocks requests to private or reserved IP addresses to mitigate potential security risks such as Server-Side Request Forgery (SSRF). However, you can enable access to internal IPs by setting the ALLOW_INTERNAL_REQUESTS environment variable in your .env file.

Steps to Enable Internal IP Requests

1. Open your .env file located in the root directory of your Heimdall installation.

2. Add the following line:

   ALLOW_INTERNAL_REQUESTS=true
   

   Setting this to true allows Heimdall to make requests to internal IP addresses (e.g., 192.168.x.x, 10.x.x.x, 127.0.0.1).

3. Save the file and clear the Laravel configuration cache:

   php artisan config:clear
   

4. Restart your web server or development server:

   php artisan serve
   

Default Behavior

If the ALLOW_INTERNAL_REQUESTS variable is not set or is set to false, Heimdall will block requests to private or reserved IP addresses and return a 403 Forbidden error.

Important Notes

• Enabling internal IP requests may expose your application to SSRF risks if your Heimdall instance is accessible from the internet. Ensure your instance is properly secured and not publicly accessible.
• Use this feature only if you trust the internal network and understand the security implications.

Running offline

The apps list is hosted on github, you have a couple of options if you want to run without a connection to the outside world:

1. Clone the repository and host it yourself, look at the .github actions file to see how to generate the apps list.
2. Download the apps list and store it as a JSON accessible to Heimdall named list.json

With both options all you need to do is add the following to your .env APP_SOURCE=http://localhost/ Where http://localhost/ is the path to the apps list without the name of the file, so if your file is stored at https://heimdall.local/list.json you would put APP_SOURCE=https://heimdall.local/
