radius-server

A lightweight, async RADIUS server library written in Rust. Built for performance, extensibility, and compatibility with FreeRADIUS-style dictionaries.

✨ Features

• ✅ Parses and builds RADIUS packets
• 📚 Loads FreeRADIUS-style dictionaries
• 🔒 Supports shared secret verification
• ⚙️ Custom packet handlers via closures
• 🧩 Vendor-Specific Attribute (VSA) support
• 🚀 Async and multithreaded using tokio

📦 Usage

radius-server = "0.1"

use std::sync::Arc; use radius_server::{dictionary::Dictionary, packet::RadiusAttribute, serve};

#[tokio::main] async fn main() -> Result<(), Box> { let dict = Arc::new(Dictionary::load_from_file("dictionaries/dictionary")?); let secret = "test123";

serve("0.0.0.0:1812", dict, secret, |packet| {
    println!("🔍 Incoming ID {} from {:?}", packet.identifier, packet.username());

    if let Some(username) = packet.username() {
        if username == "ec:30:b3:6d:24:6a" {
            Ok(packet.reply_accept(vec![
                RadiusAttribute::session_timeout(3600),
                RadiusAttribute::reply_message("Welcome, admin."),
            ]))
        } else {
            Ok(packet.reply_reject("User not allowed"))
        }
    } else {
        Ok(packet.reply_reject("Missing username"))
    }
}).await
