You have been using MSN for quite some time wondering how it works. Well You need not look any further. This article will not just tell you how MSN works but will also tell you how to make your own version of MSN messenger. You can download a sample application from here MSN Clone .Let's get ready to rumble!!!!
We can split up the working of MSN messenger into 2 phases
Authentication Phase
Instant Messaging Phase
The Authentication Phase involves logging into the MSN messenger server and also (friends) list retrieval in this case.
The Instant Messaging Phase involves sending/accepting requests for an Instant Messaging session and also sending/receiving messages.
The MSN messenger protocol is an ASCII based protocol. In other words the commands are in pure English !!!.The first phase involves connecting to an MSN messenger server .In this case we shall connect to the server 64.4.13.58 on port 1863(MSN messenger works through port 1863).
Once the connection is done we need to start the log in process. The first stage in this phase is the versioning stage. In this stage the client (in this case your app) lists/sends the versions that it can support to the server and waits for the server to respond.
VER 0 MSNP7 MSNP6 MSNP5 MSNP4 CVRO
In the MSN messenger protocol a "trial id" is sent along with every command. The trial id starts from 0 and is incremented every time the server responds successfully to the client's commands.
The server responds like this
VER 0 MSNP7 MSNP6 MSNP5 MSNP4
The Client and the server have agreed on a version in which they will communicate.
Next the client sends a request to the server asking it for the name of the security package it supports for authentication.
INF 1
Unlike Yahoo, Rediff and a few other Messengers MSN does not actually send the password as it is.It encrypts the password while sending it ensuring that your password will not be leaked out easily if somebody monitors your port.
The server responds with this
INF 1 MD5
Here MD5 is the name of the security package which the server currently supports.
Next the client sends the userid to the server
USR 2 MD5 I venky_dude@hotmail.com
Here the server does a check whether it contains all the relevant details about the user for authentication .If it does not then it sends the following reply
XFR 2 NS 64.4.13.55:1863 0
What the server says is that the client should connect to the Notification Server(NS) on 64.4.13.55 on port 1863. We close the current connection and repeat the steps while being connected to the new server i.e 64.4.13.55
(client) VER 3 MSNP7 MSNP6 MSNP5 MSNP4 CVRO
(server) VER 3 MSNP7 MSNP6 MSNP5 MSNP4
(client) INF 4
(server) INF 4 MD5
(client) USR 5 MD5 I venky_dude@hotmail.com
Now the server to which we are connected to has the relevant information about the user trying to log in. The server replies this way
USR 5 MD5 S 989048851.1851137130
The string which is sent by the server is the " MD5 Hash". It is a hash generated by the server and is used in the authentication process. The client then has to send the password which is encrypted using the MD5 algorithm.In effect the client has to send the unique MD5 equivalent of the MD5 hash i.e 989048851.1851137130 in this case and the password combined .i.e. MD5 equivalent of (hash+pass). In this case it turns out to be 3b7926d277068ec49576a0c40598ff21.
USR 6 MD5 S 3b7926d277068ec49576a0c40598ff21
If the password is right then the server replies with this
USR 6 OK venky_dude@hotmail.com venkat
Here the last word is the nickname/name by which the user is known.
In the new version of the protocol (MSNP7) the server sends additional data like some general information about the user and a authentication code something similar to a cookie which can be used for various other functions.

Now we are logged into the server but our status is still offline. We need to change our status to online in order to send and receive messages. The client does this in the following way
CHG 7 NLN
The server replies with friends who are online and in various states.
CHG 7 NLN

The next command to be sent to the server pertains to the version of the client currently being used.The client send to the server it's version number and also information about the machine like the OS and the build.
CVR 8 0x0409 win 4.10 i386 MSMSGS 4.5.0127 MSMSGS
Here 0x409 win 4.10 i386 specifies that the client is running win98 on a intel microprocessor, and MSMSGS 4.5.0127 MSMSGS here specifies the version and build no of msmsgs.exe (basically the version no of MSN messenger).
The server responds with the url to download the latest version and some other info
CVR 8 4.5.0127 4.5.0127 1.0.0863 http://download.microsoft.com/download/msnmessenger/install/4.5/win98me/en-us/mmssetup.exe http://messenger.microsoft.com
It is not necesarry to send the CVR command, the messenger protocol will function properly regardless of this command being sent
To get a list of people who are in our friends list we may send this command
LST 9 RL
On sending this command the server will reply by sending the reverse list .The reverse list is basically a list of users who can see you when you are online and send you a message.You could alternatively also request for the forward list by sending LST 9 FL .The forward list contains a list of all users whom the user has added to his/her list.
The server responds this way

*Every time a friend comes online the server(NS) sends us the following command
NLN 10NLN deaxxxx@hotmail.com Venkatesh
and when the friend goes offline the server sends us this
FLN 10 FLN deaxxxx@hotmail.com
With the MSNP7 protocol msn has introduced a new challenege authentication mechanism. The MSN server sends t a challenge key which the user has to authenticate succesfully in order for the session to continue.
CHL 0 20881396011366812350
The client has to send the md5 equivalent of this string which is formed by appending this hash with the string "Q1P7W2E4J9R8U3S5".So the final string which will be sent to the server will be the md5 equivalent of 20881396011366812350Q1P7W2E4J9R8U3S5
i.e MD5string(20881396011366812350Q1P7W2E4J9R8U3S5 )
So the client response would be something like this
QRY 18 msmsgs@msnmsgr.com 32
0212eaad0876afb8505859ca75d21a78
Here 18 is the trial id .Replace it by the appropriate trial id in your program .
The server will respond in the following way if the authentication is right
QRY 18
We have successfully logged into the MSN Messenger server. The Instant Messaging phase is next.
Instant Messaging in MSN Messenger is session based . The people in between whom the conversation is going to take place have to be in a session mode. We cannot send/receive messages unless we start a chat session with a user.Top
8 楼kingzai（stevenzhu）回复于 2005-04-04 18:05:43 得分 0
There are basically two methods in which a user can be in a chat session
User sends a chat session request to another user
User receives a chat session request from another user
User sends a chat session request
The client(user) sends a command to the server asking it for the address of the SwitchBoard(SB) server. All instant messaging conversation take place via the switchboard server.
XFR 9 SB
The server(SB) replies back with the ip address of the switchboard server(SB),the port on which to connect and a CKI hash. CKI is a security package and the client has to use the hash to connect to the switchboard server.
XFR 9 SB 64.4.13.88:1863 CKI 989487642.2070896604
Now we have to make another new connection this time to the switchboard server. Our previous connection to the MSN messenger server must be kept as it is. If we lose connection with that server we would log out.
After we have connected to the switchboard server(SB) we send the following command to the switchboard server.
USR 1 venky_dude@hotmail.com 989487642.2070896604
If the CKI hash sent by us is right the server(SB) responds back with this
USR 1 OK venky_dude@hotmail.com venkat
After this has been done the user has to "Call" the other user to the chat session. This is done by sending the following command.
CAL 2 deadxxx@hotmail.com
The server replies back with the a session id which it will pass on to the other user
CAL 2 RINGING 11717653
When the other user replies and is ready for a chat the server(SB) sends us this command
JOI deadlee@hotmail.com Venkatesh
This indicates that the other user has joined in the conversation and we are now ready to send and receive messages.
User receives a chat session request
When we are being invited to a chat session by a user the server(NS) send us the following message.
RNG 11742066 64.4.13.74:1863 CKI 989495494.750408580 deaxxxx@hotmail.com Venkatesh
Here the server(NS) sends us the session id ,the ip address of the SwitchBoard server to connect to,the port on which to connect to ,the CKI hash and the user trying to start a conversation with us.
Now we have to make another new connection this time to the switchboard server. Our previous connection to the MSN messenger server must be kept as it is. If we loose connection with that server we would log out.
We connect to the switchboard server and send the following command
ANS 1 venky_dude@hotmail.com 989495494.750408580 11742066
Here we send our login name ,the CKI hash that was sent to us and the session Id that was sent to us
The server responds back with
IRO 1 1 1 deaxxxx@hotmail.com Venkatesh
and
ANS 1 OK
We are now ready to send and receive messages.
Before sending/receiving messages let us see how the message is constructed.
When we are sending a message we build the header information in the following way
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
X-MMS-IM-Format: FN=Microsoft%20Sans%20Serif; EF=; CO=0; CS=0; PF=22
While sending a message we send it this way
MSG 2 N 137 MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
X-MMS-IM-Format: FN=Microsoft%20Sans%20Serif; EF=; CO=0; CS=0; PF=22
hello
Here 2 is the trial id which has to incremented each time we send a message. 137 is the total length of the message i.e length of the header and length of the actual message that we are sending in this case it is 'hello'.
While receiving the message it is more or less similar
Here is an example of a message received
MSG deaxxxx@hotmail.com Venkatesh 137
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
X-MMS-IM-Format: FN=Microsoft%20Sans%20Serif; EF=; CO=0; CS=0; PF=22
hello
When the other user is typing a message we receive the foll message
MSG deaxxxx@hotmail.com Venkatesh 100
MIME-Version: 1.0
Content-Type: text/x-msmsgscontrol
TypingUser: deaxxxx@hotmail.com
I guess now u guys are well on your way to make your own version of MSN messenger.Post your doubts/comments/message in the Forumn .Do visit my projects page for some cool vb & c++ codes
I'll keep adding to the protocol ,will try to put in addition functions like add/remove users ,rename user id,file transfer and voice chat, so keep checking back
References:
You could take a look at these sites for more information
This is the original protocol published by microsoft.

现在发现用MSN的COM接口是行不通了，因为我们的软件需要监视本地MSN Client的行为和消息，如对方好友发过来的音频连接请求，我们的软件需要替本地MSN Client做出接受还是拒绝的请求，不知道哪位有这方面的经验，指教一下下了。。Top

First we use a separate class that will connect to the MSN server. We call it MSNConnection. Next we build another class that handles the commands that we receive from the servers, lets call this class ServerCommand.
Next we need to declare some variables that we will use in the class MSNConnection.
private long _transactionID = 0;
private TcpClient _socket;
private NetworkStream _stream;
private StreamReader _reader;
private StreamWriter _writer;
The transactionID is sent with almost every message that we send (also in chat sessions). The _reader and _writer are the streams from the socket.
Now we have the above, let's define some functions that will do the work for us. First we need to initialize the socket and StreamReaders.
_transactionID = 0;
_socket = new TcpClient(host, port);
_stream = _socket.GetStream();
_reader = new StreamReader(_stream, Encoding.ASCII);
_writer = new StreamWriter(_stream, Encoding.ASCII);
_writer.AutoFlush = true;
We call this function ConnectSocket and it takes two parameters (host and port). Every time we make a new connection the transactionId is set to zero. If we make a function that creates the socket, why not make a function that closes the socket. Let's call it dispose.
if( _socket != null )
{
_reader.Close();
_writer.Close();
_stream.Close();
_socket.Close();
_socket = null;
}
We are making functions that read and write to the StreamReader and StreamWriter. First we define the StreamWriter. We then make a function that builds the string: WriteCommand. It takes 3 parameters: first is the command to send, next the parameters and last the option to leave the transactionId out.
string line;
// check what type of format it should be
if (bSendId)
line = string.Format("{0} {1} {2}", command, _transactionID, parameters);
else
line = string.Format("{0} {1}", command, parameters);
// Write the line
WriteLine(line, true);
The function WriteLine eventually writes the string to the StreamWriter. This function has two parameters first is the entire string and next is the option to send only a string and no end character.
if (writeNewLine)
_writer.WriteLine(line);
else
_writer.Write(line);
// raise the transactionId
_transactionID++;
We have defined some writing functions. We also need to read the information. Let's call this function ReadCommand. This function reads from the reader, if there is nothing in the socket then makes an empty ServerCommand, else we make a ServerCommand with the given response.
string line = _reader.ReadLine();
Console.WriteLine("Reading: " + line);
if (line == null)
{
Console.WriteLine("Nothing received");
return new ServerCommand();
}
else
{
return new ServerCommand(line);
}
You noticed that I use the ServerCommand object. Lets look at the ServerCommand class.
private string _cmdID;
private string _line;
private string[] _params;
public ServerCommand(string line)
{
_line = line;
// always 3 characters command
_cmdID = line.Substring(0, 3);
if (!(_cmdID == "QNG"))
{
_params = line.Substring(4).Split(' ');
}
}
public ServerCommand()
{
_line = "";
_cmdID = "ERROR";
}
If we use the constructor with a valid line, then we will get a ServerCommand with the right information. If we get a QNG command then there will be no parameters. The command is always a three letter combination. If we use the constructor with no string, then the program knows that there is something wrong.
The other functions are used for retrieving the data from this class.
public string CommandName
{
get { return _cmdID; }
}
public string Param(int index)
{
return _params[index];
}
Now all the functions are explained above, we can make the Connect function. This function needs two parameters: first is a valid username that has a passport, next is the password for that username.
First we are going to connect to the server.
string host = "messenger.hotmail.com";
int port = 1863;
ConnectSocket(host, port);
Now we are going to write the server commands, the first command we are going to write is the VER command. This command indicates what protocol we are using. We are using protocol MSNP9. We read the result in a new ServerCommand Object.
ServerCommand ServCom
WriteCommand("VER", "MSNP9 CVRO", true);
ServCom = ReadCommand();
Next we are going to check if we received the right information, if not then exit this function.
if (ServCom.CommandName != "VER")
{
return 1;
}
Now we have to send the CVR command, the parameters are the same like a real MSN messenger client. The server will response with a CVR command and a download place where you can get a newer MSN messenger, we just ignore this.
WriteCommand("CVR",
"0x0409 win 4.10 i386 MSNMSGR 5.0.0544 MSMSGS " + UserName, true);
ServCom = ReadCommand();
After this is successful, we send de USR command with a TWN parameter and your username. TWN stands for TWEENER, this is based on the passport authentication.
WriteCommand("USR", "TWN I " + UserName, true);
ServCom = ReadCommand();
If the command was not the USR command, it was probably the XFR command, this indicates to us that we have to transfer to another server. In the result is the new host and port, parse it.
string[] arIP = ServCom.Param(2).Split(':');
host = arIP[0];
port = int.Parse(arIP[1]);
Now disconnect and connect again using the new host and port.
Dispose();
We were operating in a while loop, so the connect sequence starts again. You have to send all the commands again, but this time it is to another server.
If the responsecommand is USR then we are going to connect to this server. The response will hold a ChallengeString, we need this ChallengeString to get a valid ClientTicket.
if (ServCom.CommandName == "USR")
{
ChallengeString = ServCom.Param(3);
break;
}
With the given ChallengeString we will get a valid clientticket.
string clientticket = GetClientTicket(UserPassword,
UserName, ChallengeString);
This step is a rather large step. I have already wrote an article on this part, read all about it right here.
Finally now we have a ticketID, send it to the server.
WriteCommand("USR", "TWN S " + clientticket, true);
ServCom = ReadCommand();
If we are in luck, we get the USR |transid| OK message. This indicates that we have successfully connected to the MSN servers.
Let's get our username and our screen name, this information was send together with de USR command.
_UserName = ServCom.Param(2);
_ScreenName = ServCom.Param(3);
