Have you looked at a packet log of your bot connecting? It's possible that your packet buffer is messed up - you can mange 0x50 pretty bad without getting disconnected.


             public static byte[] Create0x50(String productID, byte versionByte)
            {
               

                CultureInfo ci = CultureInfo.CurrentCulture;
                RegionInfo ri = RegionInfo.CurrentRegion;
                TimeSpan ts = DateTime.UtcNow - DateTime.Now;

                BncsPacket pack = new BncsPacket((byte)BattleNet.PacketID.SID_AUTH_INFO);
                pack.Insert(0);
                pack.InsertDwordString(BattleNet.PlatformCodes.Intel_x86);
                pack.InsertDwordString(productID);
                pack.InsertByte(versionByte);
                pack.Insert(0);
                pack.Insert(0);
                pack.Insert((int)(-ts.TotalMinutes));
                pack.Insert(ci.LCID);
                pack.InsertDwordString(string.Format("{0}{1}", ci.TwoLetterISOLanguageName, ri.TwoLetterISORegionName));
                pack.InsertCString(ri.ThreeLetterWindowsRegionName);
                pack.InsertCString(ri.DisplayName);
                return pack.GetData();
            }


That's my 0x50

and yes i noticed a big diffrence on 0x51

That is the Packet Log from Warcraft III

So diffrent.... i'll try to work on it

I tried Diablo 2 and Warcraft 3 RoC

EDIT : Maybe it helps if i show the code too


         private void HandleAuthInfo(DataReader dr)

Packet 0x51 Content:

How to fix that 0x101 ? 
I've searched the forum already and i found that MPQNumber Problem which is fixed already

Ok... i dont give up 
So i updated the 0x50 Packet.
iRes = 58 Bytes (ok seems the packet reached the server)
i still = 0

to brew : FD_CLOSE and WSAGetLastError() is C++ not C#

Here's my Code now

            IPHostEntry ip = Dns.GetHostByName("useast.battle.net");
            IPAddress[] ips = ip.AddressList;
            IPAddress battleNetIP = ips[0];

            m_clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            IPEndPoint ipEnd = new IPEndPoint(battleNetIP, battleNetPort);
            m_clientSocket.Connect(ipEnd);

            BncsPacket pck0x50 = new BncsPacket((byte)0x50);
            pck0x50.InsertDwordString("0");          // (DWORD)       Protocol ID (0)           
            pck0x50.InsertDwordString("IX86");      // (DWORD)       Platform ID
            pck0x50.InsertDwordString("D2XP");      // (DWORD)       Product ID
            pck0x50.InsertDwordString("0x0b");      // (DWORD)       Version Byte
            pck0x50.InsertDwordString("");          // (DWORD)       Product language
            pck0x50.InsertDwordString("");          // (DWORD)       Local IP for NAT compatibility
            pck0x50.InsertDwordString("");          // (DWORD)       Time zone bias
            pck0x50.InsertDwordString("");          // (DWORD)       Locale ID           
            pck0x50.InsertDwordString("");          // (DWORD)       Language ID
            pck0x50.InsertCString("USA");           // (STRING)     Country abreviation   
            pck0x50.InsertCString("United States"); // (STRING)     Country

            byte[] byteData = new byte[511];

            try
            {
                int iRes = m_clientSocket.Send(pck0x50.GetData(), SocketFlags.None);
                richTextBox1.AppendText("0x50 : " + iRes + " Bytes sent\n");
            }

            catch (Exception exp)
            {
                richTextBox1.AppendText("Exception : " + exp.Message + "\n");
                return;
            }

            int i = m_clientSocket.Receive(byteData);
            richTextBox1.AppendText("Bytes Received : " + i + "\n");

EDIT : Is it better to use Network Stream instead of this what i am doing here ?

            BncsPacket pck0x50 = new BncsPacket((byte)0x50);
            pck0x50.InsertInt32(0);             
            pck0x50.InsertDwordString("IX86"); 
            pck0x50.InsertDwordString("D2XP");
            pck0x50.InsertByte(0x0A);             
            pck0x50.InsertInt32(0);             
            pck0x50.InsertInt32(0);             
            pck0x50.InsertInt32(0);             
            pck0x50.InsertInt32(0);             
            pck0x50.InsertDwordString("", 0);   
            pck0x50.InsertCString("USA");       
            pck0x50.InsertCString("United States");

            byte[] byteData = new byte[511];

            try
            {
                m_clientSocket.Send(pck0x50.GetData(), SocketFlags.None);
                richTextBox1.AppendText("Sending 0x50\n");
            }

            catch (Exception exp)
            {
                richTextBox1.AppendText("Exception : " + exp.Message + "\n");
                return;
            }

            int i = m_clientSocket.Receive(byteData);
            richTextBox1.AppendText("Bytes Received :" + i + "\n");


i is still 0 .. 

0x01 ? Sorry didnt find that
I had a look right here : http://ersan.us/src/bnetdocs/sequence.html

it says:

SEND ->   SID_AUTH_INFO   (0x50)
RECV <-   SID_PING   (0x25)
RECV <-   SID_AUTH_INFO   (0x50)

So would it be enough with

BncsPacket pck0x01 = new BncsPacket((byte)0x01);

and then send this packet ?

Im new to C# (learning it for 2 Month now) and i tried the simpliest thing : Sending 0x50 and receive an answer.
For this i use MBNCSUtil ( using MBNCSUtil; )
This is what i wrote

            IPHostEntry ip = Dns.GetHostByName("useast.battle.net");
            IPAddress[] ips = ip.AddressList;
            IPAddress battleNetIP = ips[0];

            richTextBox1.AppendText("Address of useast.battle.net : " + battleNetIP + "\n");

            m_clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            IPEndPoint ipEnd = new IPEndPoint(battleNetIP, battleNetPort);
            try
            {
                m_clientSocket.Connect(ipEnd);
            }
            catch (Exception exp)
            {
                richTextBox1.AppendText("Exception : " + exp.Message + "\n");
                return;
            }

            if(m_clientSocket.Connected)
                richTextBox1.AppendText("Connected\n");

            BncsPacket pck0x50 = new BncsPacket((byte)0x50);
            pck0x50.InsertInt32(0);             
            pck0x50.InsertDwordString("IX86"); 
            pck0x50.InsertDwordString("D2XP"); 
            pck0x50.InsertInt32(0);             
            pck0x50.InsertInt32(0);             
            pck0x50.InsertInt32(0);             
            pck0x50.InsertInt32(0);             
            pck0x50.InsertInt32(0);             
            pck0x50.InsertDwordString("", 0);   
            pck0x50.InsertCString("USA");       
            pck0x50.InsertCString("United States");

            byte[] byteData = new byte[32];

            try
            {
                m_clientSocket.Send(pck0x50.GetData(), SocketFlags.None);   
            }

            catch (Exception exp)
            {
                richTextBox1.AppendText("Exception : " + exp.Message + "\n");
                return;
            }

            int i = m_clientSocket.Receive(byteData);
            richTextBox1.AppendText("Bytes Received :" + i + "\n");

Its my first time i try to use Sockets in C#. Anyways .. i = 0, means i received 0 bytes.
What did i do wrong ?

Ok first im programming with C++ and i simply want to connect to europe.battle.net and did this so far :


#include <winsock2.h>
#include <windows.h>
#include <iostream.h>
#include <string.h>

#pragma comment(lib,"wsock32.lib")

int main()
{
char *ip;
long rc;

WSADATA wsa;
WSAStartup(MAKEWORD(2,0),&wsa);
SOCKET s;
SOCKADDR_IN addr;
HOSTENT* EuropeBattleNet;

memset(&addr,0,sizeof(SOCKADDR_IN));
s=socket(AF_INET,SOCK_STREAM,0);
he=gethostbyname("europe.battle.net");
ip = inet_ntoa( *(LPIN_ADDR)*EuropeBattleNet->h_addr_list );

addr.sin_family=AF_INET;
addr.sin_port=htons(6112);
addr.sin_addr.s_addr=inet_addr(ip);

cout<<"Trying to connect to europe.battle.net "<< ip <<"\n\n";

rc=connect(s,(SOCKADDR*)&addr,sizeof(SOCKADDR));

if(rc==SOCKET_ERROR)
cout<<"Error";
else
cout<<"Connected !\n";

return 0;
}


Now i read about SID_AUTH_INFO ( http://bnetdocs.valhallalegends.com/content.php?Section=m&Code=2 )

(DWORD)       Protocol ID (0)
(DWORD)       Platform ID
(DWORD)       Product ID
(DWORD)       Version Byte
(DWORD)       Product language
(DWORD)       Local IP for NAT compatibility*
(DWORD)       Time zone bias*
(DWORD)       Locale ID*
(DWORD)       Language ID*
(STRING)     Country abreviation
(STRING)     Country

Now i have to use send(socket,thingtosend,MAX_PATH,0); for every thing ? ( i mean for every listed thing (protocol id etc) )
Its so hard to understand for me
