Strange Java Socket Behavior (Connects, but Doesn't Send)

I have a fairly complex project that boils down to a simple Client / Server communicating through object streams. Everything works flawlessly for two consecutive connections (I connect once, work, disconnect, then connect again, work, and disconnect). The client connects, does its business, and then closes. The server successfully close...

Unit testing UDP socket handling code

Are there any 'good' ways to cause a thread waiting on a recvfrom() call to become unblocked and return with an error? The motivation for this is to write unit tests for a system which includes a unit that reads UDP datagrams. One of the branches handles errors on the recvfrom call itself. The code isn't required to distinguish between...

Unix Sockets in Go

I'm trying to make a simple echo client and server that uses Unix sockets. In this example, the connection seems to be unidirectional. The server can receive data from the client, but it can't send the data back. If I use tcp connections instead, it works great. Does anyone know what's wrong? Server package main import "net" import "f...

Communicate between separate MPI-Programs

I have the following problem: Program 1 has a huge amount of data, say 10GB. The data in question consists of large integer- and double-arrays. Program 2 has 1..n MPI processes that use tiles of this data to compute results. How can I send the data from program 1 to the MPI Processes? Using File I/O is out of question. The compute no...

.Net 3.5 Asynchronous Socket Server Performance Problem

I'm developing an Asynchronous Game Server using .Net Socket Asynchronous Model( BeginAccept/EndAccept...etc.) The problem I'm facing is described like that: When I have only one client connected, the server response time is very fast but once a second client connects, the server response time increases too much. I've measured the time...

Socket connection to a telnet-based server hangs on read

I'm trying to write a simple socket-based client in Python that will connect to a telnet server. I can test the server by telnetting to its port (5007), and entering text. It responds with a NAK (error) or an AK (success), sometimes accompanied by other text. Seems very simple. I wrote a client to connect and communicate with the ser...

C socket programming: select() is returning 0 despite messages sent from server

Hey all, I'm using select() to recv() messages from server, using TCP/IP. When I send() messages from the server, it returns a reasonable number of bytes, saying it's sent successful. And it does get to the client successfully when I use while loop to just recv(). Everything is fine and dandy. while(1) recv() // obviously pseudocode...
