LanCtrl

HTTP-based shortcut execution and remote control for your PC.

lanctrl spins up a lightweight web server that listens for incoming requests and simulates keyboard events on the host machine. This allows you to control your computer (e.g., switch tabs, pause media, close windows) from any device on your local network, such as a phone or tablet.

Installation

From Releases

• Download the latest pre-compiled binary for your platform from the GitHub Releases page.
• Run the executable (e.g., ./lanctrl on Linux/macOS or lanctrl.exe on Windows).

Build from Source

Prerequisites

• Go (1.20 or later recommended)

1. Clone the repository:

   git clone https://github.com/dhr412/lanctrl.git
   cd lanctrl

2. Install dependencies:

   go mod tidy

3. Build the binary:

   go build -o lanctrl src/main.go

   Note: If you are compiling on Linux, you may need additional libraries for the keybd_event package (e.g., libx11-dev).*

How It Works

The application initializes a local HTTP server (defaulting to port 8075). Each defined route corresponds to a specific key combination using the keybd_event library. When a route is hit, the server simulates the key press on the host OS.

It automatically attempts to detect your local IP address on the "Wi-Fi" interface to make connection easier.

Usage

Run the application:

./lanctrl

Or specify a custom port:

./lanctrl -port 9090

Send a request to trigger an action (e.g., from a browser or using curl):

curl http://<YOUR_PC_IP>:8075/<endpoint>

or Visit http://<YOUR_PC_IP>:8075/<endpoint> in your browser
