Im using Erica Sadun's CookBook code to open a socket on the iPad and use a browser on my desktop to connect to the socket, provide a list of file (in this case audio files) and allow the user to downloand them to their desktop.

Any suggestions on testing a TCP client listener. What I'm looking for is actual network stats like "payload size", "time-out values", "actual payload bytes received from server". public static void tcpConnect() { int port = 12345; IPEndPoint ipep = new IPEndPoint( IPAddress.Parse("xx.xx.xx....
Can local message-based sockets transfer messages up to the SO_SNDBUF/SO_RCVBUF limits, or where can the so-called 'fixed maximum length' be determined for a descriptor created with socket(PF_UNIX, SOCK_SEQPACKET, 0) or socket(PF_UNIX, SOCK_DGRAM, 0)? ...
I'm trying to optimize some code that I have that requires me to try and contact a few bluetooth devices using RFCOMM. Right now it's taking at least 2 seconds to successfully open a socket to any of the devices. Is this kind of delay normal? ...

I asked this question before and had no resolution (still having the problem). I am stumped because the function returned without error and NO DATA was sent! This code works on Linux ... the VxWorks version does not work (sendto does not send, though it returns without an ERROR). The synopsis - I am writing a simple echo server - The se...
Hello all. I was using the following code to send data asynchronously but I noticed that using WaitOne in the AsyncWaitHandle that I get from asyncRes doesn't wait at all. I checked MSDN and it says I should use a ManualResetEvent. ... var asyncRes = _socket.BeginSend(encodedFrame, 0, encodedFrame.Length, SocketFlags.None, sendCallback,...

I have all traffic from port 50 redirected to 5050 using iptables -t nat -A POSTROUTING -p udp --dport 50 -j REDIRECT --to-port 5050 I listen using a RAW Socket on 5050, and I see IP packets from 0.0.0.0:50 to 0.0.0.0:5050. The original destination address is obviously not present, since this seems to be a separate redirection packet...
The OpenSSL library allows to read from an underlying socket with SSL_read and write to it with SSL_write. These functions maybe return with SSL_ERROR_WANT_READ or SSL_ERROR_WANT_WRITE depending on their ssl protocol needs (for example when renegotiating a connection). I don't really understand what the API wants me to do with these res...

I need to log socket usage, and I wrote a LD_PRELOAD library. The problem is when I override read() and write() than ordinary file operations are get logged too (of course). So how can I tell ordinary file descriptors and socket descriptors apart? ...
Is there any reason why the server process does not give any output in the following code? require 'socket' server = TCPServer.open(3000) loop{ puts "waiting for connection" client = server.accept puts "connection!" client.close puts "client closed" } I connect via: nc localhost 3000 in a windows cygwin environ...

With respect to C# and .NET's System.Net.Sockets.Socket.AcceptAsync method, one would be required to handle a return value of "false" in order to handle the immediately available SocketAsyncEventArgs state from the synchronously processed connection. Microsoft provides examples (found on the System.Net.Sockets.SocketAsyncEventArgs class ...
