Need help on sending an rcon command to a Call of Duty server

[Teh Rar File]

Hello, I have become very interested in network programming and have a cool idea for my clan but I am a little confused as to how to it. Basically I would like to obtain info from a website and send this data to the server via rcon. Fetching the html data is cake but I'm stumped on sending an rcon command...
I would really appreciate it if anyone can help. I have been googling for a while now so I might have missed it.

Woops forgot to mention I am doing this in c#.

Closest thing I could find, [url]http://github.com/aiusepsi/SourceRcon/tree/master[/url] But that only works with source's specific implementation of the rcon protocol..

Thanks.

Searching for "CoD rcon protocol" is yay easy, but I believe the network layer is right off Quake 3's, according to [url]http://icculus.org/pipermail/cod/2008-July/011106.html[/url].

I got a C# app working with (COD4) rcon, but it was a right pain sorting out the receiving end - sometimes you get duplicate packets, sometimes nothing comes through, sometimes it's corrupted and you have no way of knowing...anyway, not sure if I still have the app. I'll have a look.

Cool, should be useful.

It's the magic of UDP :downs:

The receive side of things, threaded and looping (and naturally, inefficient as hell):

        public void Recieve() //remember to end the thread when you quit
        {
            while (true)
            {
                Thread.Sleep(1);

                int avail = client.Available;

                if (avail > 0)
                {
                    byte[] receiveBuffer = new byte[avail];
                    client.Receive(receiveBuffer, avail, SocketFlags.None);
                    string toadd = System.Text.Encoding.UTF8.GetString(receiveBuffer);

                    if(toadd.IndexOf("print") == 4)
                        toadd = toadd.Substring(10);

                    data += toadd; //data is a global string
                }
            }
        }

Sending:

            byte[] actualCommand = System.Text.Encoding.ASCII.GetBytes(
                        "rcon " + "password" + " " + "commands");

            //e.g: rcon 1234 status

            byte[] bufferSend = new byte[actualCommand.Length + 5];

            bufferSend[0] = byte.Parse("255");
            bufferSend[1] = byte.Parse("255");
            bufferSend[2] = byte.Parse("255");
            bufferSend[3] = byte.Parse("255");
            bufferSend[4] = byte.Parse("02");
            int j = 5;

            for (int i = 0; i < actualCommand.Length; i++)
            {
                bufferSend[j] = actualCommand[i];
                j++;
            }

            try
            {
                client.Connect("192.168.1.1", 28960);
                client.Send(bufferSend, bufferSend.Length, SocketFlags.None);
            }
            catch (SocketException)
            {
//stuff
            }
            catch (InvalidOperationException)
            {
//stuff
            }

            Thread.Sleep(700); //the receiving thread time to get data
