I have a main thread that waits for connection. It spawns client threads that will echo the response from the client (telnet in this case). But say that I want to close down all sockets and all threads after some time, like after 1 connection. How would I do? If I do clientSocket.close() from the main thread, it won't stop doing the recv...
Is there an established way to determine whether the other end of a TCP connection is closed in the asio framework without sending any data? Using Boost.asio for a server process, if the client times out or otherwise disconnects before the server has responded to a request, the server doesn't find this out until it has finished the requ...
Hi, I am a complete newbie when it comes to python, and programming in general. I've been working on a little webapp for the past few weeks trying to improve my coding chops. A few days ago my laptop was stolen so I went out and got a new MacBook Pro. Thank God I had everything under subversion control. The problem is now that I am ...
I'm trying to write a php code that acts as a server. All it would do is connects two socket, it opens a file socket and pipes everything from it into another socket that it connects to. It would run 24/7. I'm not familiar with PHP but this project requires it. Any help? ...
My fwrite to a socket is not flushed, until the socket closes. How to change? I want it to flush after each fwrite. I've tried: 1) flush() 2) fflush() 3) ob_implicit_flush(true); None of those worked, I still had to quit php for my socket to receive the data. Including some sample code, anything looks wrong? while($clientSocket =...
I used python's socket module and tried to open a listening socket using import socket import sys def getServerSocket(host, port): for r in socket.getaddrinfo(host, port, socket.AF_UNSPEC, socket.SOCK_STREAM, 0, socket.AI_PASSIVE): af, socktype, proto, canonname, sa = r try: ...
That's odd, TBaseSocket's WaitForData documentation specifies that you should call it before SendBuf and Sendln calls. I had a quick try and (perhaps because I trying to write first) this WaitForData call returns false. (after timing out the specified timeout) So is this incorrect? Or incomplete? Or only valid in a number of circumstanc...
Hello everybody I'm trying to manually create the file descriptor associated with a socket in python and then loaded directly into memory with mmap. Create a file into memory with mmap is simple, but I can not find a way to associate the file with a socket. Anyone know how? thank you very much. ...

I have a project to develop a client server application in java. This is to be done using socket programming. Our lecturer, used 2 files, the TCPClient.java and TCPServer.java, to make a connection and we typed "Hi" in the client and the server displayed that message. I need to develop a seat booking application. Any suggestions for...
Before disconnect the client, the server wants to send some info to the client - why do I(server) disconnect you(client). If I send packet to the info and close the client socket immediately, closesocket() returns -1 and if I use linger option to work closesocket() successfully, the info cannot be sent completely. How can I complete t...

I have a file with millions of URLs/IPs and have to write a program to download the pages really fast. The connection rate should be at least 6000/s and file download speed at least 2000 with avg. 15kb file size. The network bandwidth is 1 Gbps. My approach so far has been: Creating 600 socket threads with each having 60 sockets and us...
Hi, i would like to know, what is the best way to send files between python and C# and vice versa. I have my own protocol which work on socket level, and i can send string and numbers in both ways. Loops works too. With this i can send pretty much anything, like package of users id, if it is simple data. But soon i will start sending wh...

Seems, that after cancelling and close it it still saves somewhere a socket that I was connected to server with and while the server fetches for information i cannot access another urls from the same server. I wonder if there is a way to completely reset a socket and start another ...
I have a PHP CLI script mostly written that functions as a chat server for chat clients to connect to (don't ask me why I'm doing it in PHP, thats another story haha). My script utilizes the socket_select() function to hang execution until something happens on a socket, at which point it wakes up, processes the event, and waits until t...
Hi there. I'm currently busy working on an IP ban tool for the early versions of Call of Duty 1. (Apparently such a feature wasn't implemented in these versions). I've finished a single threaded application but it won't perform well enough for multiple servers, which is why I am trying to implement threading. Right now, each server ha...
I'm writing a Ruby class that extends TCPSocket. Assume it looks something like this: class FooSocket < TCPSocket def hello puts 'hello' end end I have a TCPServer listening for incoming connections server = TCPServer.new 1234 socket = server.accept When my server finally accepts a connection, it will return a TCPSo...
I'm trying to take advantage of HTML 5 web sockets in .NET and the easiest way appears to be something like what this guy does. I've already tested this myself and it works great, but there are a few problems if I try to deploy this to my hosting site (discountasp.net). Basically, I am not allowed to open up a port on 8080 and listen o...
