# kysdk-dbus-websocket(1)

KYLIN SDK D-Bus to WebSocket Bridge

## NAME

kysdk-dbus-websocket - KYLIN SDK D-Bus to WebSocket Bridge

## SYNOPSIS

**kysdk-dbus-websocket**

## DESCRIPTION

**kysdk-dbus-websocket** is a background service that provides a bridge between D-Bus system services and WebSocket connections. This service enables JavaScript applications to access KYLIN SDK D-Bus interfaces through WebSocket connections, facilitating web-based interaction with system-level functionality.

The service acts as a proxy that translates WebSocket messages to D-Bus method calls and signals, allowing web applications to interact with native system services without direct D-Bus access.

## FEATURES

- **D-Bus to WebSocket Bridge**

  Translates between D-Bus protocol and WebSocket protocol

- **JavaScript Interface**

  Provides web-based access to D-Bus services for JavaScript applications

- **Automatic Startup**

  Configured to start automatically with the desktop session

- **Background Operation**

  Runs silently in the background without user interface

## AUTOSTART CONFIGURATION

The service is configured to start automatically with the desktop environment:

- **Desktop Entry**

  Installed as a hidden desktop application (NoDisplay=true)

- **Startup Delay**

  Configured with a 15-second delay (X-MATE\_Autostart-Delay=15)

- **Execution Path**

  /usr/bin/kysdk-dbus-websocket

## FILES

- **/usr/bin/kysdk-dbus-websocket**

  Main executable file

- **/etc/xdg/autostart/kysdk-dbus-websocket.desktop**

  Autostart desktop entry file

- **~/.config/autostart/kysdk-dbus-websocket.desktop**

  User-specific autostart configuration (if customized)

## FUNCTIONALITY

- **WebSocket Server**

  Listens for WebSocket connections on a configured port

- **D-Bus Proxy**

  Forwards WebSocket requests to appropriate D-Bus services

- **Signal Broadcasting**

  Broadcasts D-Bus signals to connected WebSocket clients

- **JSON Protocol**

  Uses JSON formatting for message exchange between WebSocket clients and D-Bus services

## SUPPORTED INTERFACES

The service typically bridges common KYLIN SDK D-Bus interfaces including: - System information services - Hardware monitoring services - Network management services - Power management services - Process management services

## NETWORK CONFIGURATION

- **WebSocket Port**

  Listens on a predefined port (typically configured in the application)

- **Local Access**

  Usually restricted to localhost connections for security

- **Protocol Support**

  Supports standard WebSocket protocol with JSON message format

## SECURITY

- **Access Restrictions**

  Limited to localhost connections to prevent remote exploitation

- **Privilege Level**

  Runs with user privileges, not system privileges

- **Interface Filtering**

  May implement filtering to restrict accessible D-Bus interfaces

## DEPENDENCIES

- **D-Bus**

  For communication with system services

- **WebSocket Library**

  For WebSocket protocol implementation

- **Desktop Environment**

  For autostart functionality (MATE/GNOME/KDE)

## MONITORING

- **Process Status**

  Can be monitored through standard process management tools

- **Connection Tracking**

  May provide connection statistics and client tracking

- **Log Output**

  Outputs to standard logging facilities

## TROUBLESHOOTING

- **Service Status**

  Check if the process is running with "ps aux \| grep kysdk-dbus-websocket"

- **Manual Start**

  Can be started manually by running "/usr/bin/kysdk-dbus-websocket"

- **Log Files**

  Check system logs or desktop environment logs for error messages

## ENVIRONMENT

- **DISPLAY**

  Requires X11 display for desktop session integration

- **DBUS\_SESSION\_BUS\_ADDRESS**

  Needs access to session D-Bus for service communication

- **HOME**

  Uses home directory for potential configuration files
