Overview

Radius.NET is a Radius client built on the .NET 4.5 runtime. It currently only supports the PAP protocol. Other protocols will be added if needed. Pull requests are also welcome.

Requirements

.NET 4.5 installed

Example Usage

var hostname = "UBUNTU-RADIUS";
var sharedKey = "test";
var username = "User1";
var password = "test";

var rc = new RadiusClient(hostname, sharedKey);
var authPacket = rc.Authenticate(username, password);
authPacket.SetAttribute(new VendorSpecificAttribute(10, 1, UTF8Encoding.UTF8.GetBytes("Testing")));
authPacket.SetAttribute(new VendorSpecificAttribute(10, 2, new[] {(byte)7}));
var receivedPacket = rc.SendAndReceivePacket(authPacket).Result;

if (receivedPacket == null) 
	throw new Exception("Can't contact remote radius server !");

switch (receivedPacket.PacketType)
{
	case RadiusCode.ACCESS_ACCEPT:
		Console.WriteLine("Access-Accept");
		foreach (var attr in receivedPacket.Attributes)
			Console.WriteLine(attr.Type.ToString() + " = " + attr.Value);
		break;
	case RadiusCode.ACCESS_CHALLENGE:
		Console.WriteLine("Access-Challenge");
		break;
	case RadiusCode.ACCESS_REJECT:
		Console.WriteLine("Access-Reject");
		if (!rc.VerifyAuthenticator(authPacket, receivedPacket))
			Console.WriteLine("Authenticator check failed: Check your secret");
		break;
	default:
		Console.WriteLine("Rejected");
		break;
}
