thefcraft/linkifyr

Linkifyr is a Python script that enables port forwarding functionality. It allows users to forward network traffic from one port to another, facilitating various network-related tasks such as proxying, tunneling, and redirecting traffic between different hosts or processes.

Linkifyr Tunnel

This project implements a tunnel service similar to Ngrok, allowing users to expose their local servers to the internet securely. The implementation consists of a client-side application (client.py) and a server-side application (app.py) using FastAPI for handling WebSocket connections and HTTP requests.

Download

linkifyr.exe

to run open cmd and ./linkifyr.exe --url http://127.0.0.1:5000/ --server_url linkifyr.thefcraft.site --server_protocol https

Features

• Dynamic urls like https://{client_id}.linkifyr.thefcraft.site
• Securely exposes local servers to the internet.
• Handles HTTP/HTTPS requests and forwards them to the local server.
• Displays connection status and information using Rich for a better CLI experience.

DEMO

python client.py --url http://127.0.0.1:5000/

Your site http://127.0.0.1:5000/ is live at https://62dc-f9-d0-9f65.linkifyr.thefcraft.site

Getting Started

Prerequisites

• Python 3.7+
• aiohttp
• requests
• fastapi
• uvicorn
• rich
• cryptography

Install the required packages using pip:

pip install aiohttp requests fastapi uvicorn rich cryptography

Client-Side Application

The client-side application (client.py) connects to the server, retrieves a unique client ID, and establishes a WebSocket connection for forwarding requests.

Usage

Run the client-side application with the following command:

python client.py --url http://127.0.0.1:5000/ --server_url Ilinkifyr.thefcraft.site --server_protocol https

Arguments

• --url: The local URL to be exposed (default: http://127.0.0.1:5000/).
• --server_url: The server URL to connect to (default: dev.thefcraft.site).
• --server_protocol: The protocol to use for server connection (http or https, default: https).

Server-Side Application

The server-side application (app.py) uses FastAPI to handle incoming WebSocket connections and HTTP requests, forwarding them to the appropriate client.

Running the Server

Run the server-side application with the following command:

uvicorn app:app --host 0.0.0.0 --port 8080

dns config

use wildcard domain

adding a wildcard custom domain on onrender

Workflow

1. Client Connection: The client connects to the server and retrieves a unique client ID.
2. WebSocket Connection: The client establishes a WebSocket connection using the retrieved client ID.
3. Request Forwarding: The server forwards incoming HTTP requests to the connected client, which processes them and returns the response.

feature request

Hii
Please add feature forward proxy to socks4/5 external proxy, also if domain/url resolve to localhost/127.0.0.1 bypass it from use proxy.
Thanks for your hard work
