Getting Started

Private Server

Architecture of the Private Server mode

To enhance privacy, you can host a private server within your own infrastructure, ensuring that all messages remain solely on devices you control. The only required external network connection is for sending push notifications via the public server at api.sms-gate.app. This setup eliminates the need to configure Firebase Cloud Messaging (FCM) or rebuild the Android app, but it does demand some technical know-how.

Prerequisites

  • A MySQL or MariaDB database server with an empty database, and a user granted full access to that database.
  • A Virtual Private Server (VPS) running Linux with Docker installed.
  • A reverse proxy with a valid SSL certificate and HTTPS enabled.

Run the Server

  1. Create a config.yml file based on the template provided in config.example.yml. Pay special attention to the database, http, and gateway sections. Environment variables can be used to override values in the config file.
  2. Set gateway.mode to private.
  3. Define gateway.private_token as the access token for device registration in private mode. Ensure this token matches the one on the devices set to private mode.
  4. Start the server in Docker with the following command: 
    docker run -p 3000:3000 -v $(pwd)/config.yml:/app/config.yml \
 capcom6/sms-gateway:latest
  5. Configure your reverse proxy, enable SSL, and modify your firewall settings to permit Internet access to the server.

Refer to the server's README.md for more information.

Example settings for Private Server mode

Note: Changing the server will invalidate current credentials, and the device will be re-registered with new ones.

  1. Navigate to the Settings tab.
  2. In the Cloud Server section, enter the API URL and Private token, ensuring they match those in the server configuration. Note that you should include the full URL with the path, such as https://private.example.com/api/mobile/v1.
  3. Switch to the Home tab.
  4. Activate the Cloud server option.
  5. Apply the new configuration by stopping and starting the app using the button at the bottom of the screen.

If everything is configured correctly, the new credentials for the private server will be displayed in the Cloud Server section on the Home tab.

Password Management

The password management process is identical to the Cloud Server mode.
