I've been searching around and have had little luck. I'm looking for a python custom TCP stack implementation that I can modify to add predictable SYN & ACK sequence numbers while keeping all the other goodness of TCP the same (out of order packets, missing, duplicates, etc.. fixed).
Any ideas?

PS. this only needs Linux support, Mac and win support is optional

I am trying to emulate telnet functionality by writing a socket listener program, and an application redirecting its console to the listener over sockets.

On the server side I opened a socket on my local ip, a defined port, and started listening on it like this

Code:

sockfd = socket(AF_INET,SOCK_STREAM,0);
portno = atoi(argv[1]);
serv_addr.sin_family = AF_INET;
serv_addr.sin_addr.s_addr = INADDR_ANY;
serv_addr.sin_port

Socket.Disconne ct(bool reuse) according to msdn enables the program to reuse the socket
my questions are:

1)
if we decide to reuse the socket does that mean it will reuse the same local end point as well,what i'm asking is,
would it preserve the port for that socket or would it just(i don't believe it does)
save all the objects resources ?

2)if in effect it does only save the resources...

I've build TicTacToe game, and got it to work multiplayer. I have used one java server for connecting to the database and with the clients ( sockets ).

It works fine but now I am wondering if I could only make the clients connect to the database and receive/update data from there (whose turn it is and what move someone made), without any Java server and sockets.

Please help me on this one. Should I use sockets or not,...

Hello,

I implented a socket client to communicate to an ip camera with RTSP over HTTP to get teh video from the camera.

To stablished the communication with the camera, first i have to set an HTTP-GET tunnel, then send the RTSP commands. When the camera loses the connection, the program has to close the tunnel handler, finish the thread and when the process return to the main function, it begins the communication (start...

Hello, I am currently trying to create a server/client file transfer system in which the server sends the client .mp3 files. The file transfers fine but when I go to play the file, it is all scratchy and skips and I think it has something to do with the bytes that I am sending.

Here is the server code:

Code:

byte[] fileData = File.ReadAllBytes(sData);
                       byte[] clientData = new byte[4 + fileData.Length];

The code below works fine. As of now I just set the buffer length real big and all is good. However, I hate the impreciseness of that.

So my question in general is how do I know what length to set the buffer? In specific, my question is what causes the 'completed' event in the OnSocketConnect Completed method to fire? Does it fire at end of a packet or does happen at some end of data marker?

Code:

        public SocketClient(Page
