RDScanner

A tool to test proxy configurations using xray-knife.

What it does

Reads a list of proxy configs (vless, vmess, trojan, ss, etc.) and tests each one against multiple HTTP endpoints to find which ones are alive and working.

Requirements

• .NET 8.0
• xray-knife.exe in the same folder

Setup

1. Create a RESULTS folder
2. Put your configs in RESULTS/tcp_alive.txt
3. Put xray-knife.exe in the root folder

Run

dotnet run

The program will ask for:

• Number of threads
• Delay between requests (ms)

Input Format

One config per line in tcp_alive.txt:

vless://uuid@server.com:443?encryption=none vmess://base64... trojan://password@server.com:443

Output

Results saved to RESULTS/Really_alive.txt with timestamp and verification status.

Configuration

Edit Config section in Program.cs:

• TestURLs: URLs used for testing
• ScanThreads: concurrent workers
• MdelayMs: delay between requests
• EnableVerification: test with YouTube

Files
