Would you consider adding:
STATUS_SERVER = 12,
as one of the enumerated RADIUS codes
at line 16 of Radius.NET?

Code 12 is shown as "experimental"
in RFC 2865 and gets a full treatment
in RFC 5997.
Your RADIUS client is used by PRTG and a sensor
that made use of a Status-Server code
would make for a very light-weight sensor.

Can I authenticate VPN PPTP?

What would be solution for the use of MS-CHAP v2?

Hi.
when Auth but did not console write Accept
also, when Auth fail then write Reject hope.
Thanks

It looks like the project should be .NET Standard 2.0 compatible as-is.
Just update the project format and multi-target for net45 and netstandard20.

I have created new MVC Web Application and trying to integrate VIP Access Notification but I am not able to receive response from line "RadiusPacket receivedPacket = await rc.SendAndReceivePacket(authPacket);"

Below is my Code in Home Controller.

public ActionResult Index()
{
string[] args = new string[4];
args[0] = "MYIP";
args[1] = "KEY";
args[2] = "UserName";
args[3] = "Password";

        try
        {
            Authenticate(args).Wait();
        }
        catch (Exception e)
        {
            //Console.WriteLine(e);
        }
        return View();
    }

Below is my Authenticate function
private async static Task Authenticate(string[] args)
{

        RadiusClient rc = new RadiusClient(args[0], args[1], 60000, 1822);
        RadiusPacket authPacket = rc.Authenticate(args[2], args[3]);
        authPacket.SetAttribute(new VendorSpecificAttribute(10135, 1, UTF8Encoding.UTF8.GetBytes("Testing")));
        authPacket.SetAttribute(new VendorSpecificAttribute(10135, 2, new[] { (byte)7 }));
        RadiusPacket receivedPacket = await rc.SendAndReceivePacket(authPacket);
        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("Enter Secret : ");
                string secret = Console.ReadLine();
                args[3] = args[3] + secret;
                RadiusClient rc1 = new RadiusClient(args[0], args[1], 60000, 1822);
                RadiusPacket authPacket1 = rc1.Authenticate(args[2], args[3]);
                authPacket1.SetAttribute(new VendorSpecificAttribute(10135, 1, UTF8Encoding.UTF8.GetBytes("Testing")));
                authPacket1.SetAttribute(new VendorSpecificAttribute(10135, 2, new[] { (byte)7 }));
                RadiusPacket receivedPacket1 = await rc1.SendAndReceivePacket(authPacket1);
                Console.WriteLine(receivedPacket1.PacketType);
                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;
        }
    }

I am getting notification in my mobile device but after selecting any of the option (e.g. Approve Or Deny) I am not getting response of selected event.

NOTE: Same thing is working fine in my console application.

Let me know if I missed anything in code.

Thanks for building this. Is there a way to use this code to change the radius password? I work with a tool that sets an initial password, but then sets the account into a "user must change password at next use" mode. This translates into a "access-challenge" result. But some applications, such as Cisco Anyconnect VPN, can prompt the user to change the password when they receive this challenge.

Is there a way to do this with your code?

Thanks!

Steve

_Length field of RadiusPacket is always 18 lower than the RawData.Length after SetMessageAuthenticator is called.

Hi guys,

Maybe not the right site but for the love of God i can't seem to add an additional parameter to be sent to radius. I have done everything semantically and syntactically correct but the server send an error of malformed massage.

Any ideas or examples?

Does the code code supports the CHAP ?
