问题 Quite new to multiprocessing here. I have a code that runs two processes. One to continuously receive data blocks from the server and put it inside a queue and the other to remove the data blocks from the queue and process it. Below is my client code: import socket import turtle import multiprocessing from multiprocessing import Process, Queue from tkinter import * class GUI: def __init__(self, master): rec_data = recv_data() self.master = master master.title("Collision Detection") self.input

问题 I am attempting to run a TCP server from my UWP App. However i cannot connect to the server from another application (which im running on the same PC). I tried using the telnet command. This snippet works correctly if i use it in a command Line Application, in the UWP app it does execute, but never gets any connection requests. TcpListener serverSocket = new TcpListener(System.Net.IPAddress.Parse("127.0.0.1"), 3457); int requestCount = 0; TcpClient clientSocket = default(TcpClient);

问题 I'm trying to find the file descriptors for all TCP sockets of a given process, ie. given its pid, so that I can get the socket option at another process without modifying the original one. For example, if I know the file descriptor is fd , then I hope to call getsockopt(fd, ...) to retrieve the options at another process. I'm wondering is this doable? If so, how to get the fd I need outside the original process? I have tried to print out the return value when creating a socket, ie. s =

问题 Is there a way to tell Python urllib3 to not reuse idle connections after some period of time, and instead to close them? Looking in https://urllib3.readthedocs.io/en/latest/reference/index.html#module-urllib3.connectionpool doesn't seem to show anything relevant. 回答1: Remember: A connection pool is a cache of database connections maintained so that the connections can be "reused" when future requests to the database are required. You can do this is many ways (I guess): Set retries to one.

问题 Hello I am new on spring integration I checked examples for Spring Integration dynamic routing. Finally ı found it in here Dynamic TCP Client In here there were lines @Component @MessagingGateway(defaultRequestChannel = "toTcp.input") public interface TcpClientGateway { byte[] send(String data, @Header("host") String host, @Header("port") int port); } private MessageChannel createNewSubflow(Message<?> message) { String host = (String) message.getHeaders().get("host"); Integer port = (Integer)

问题 I've been using the pcap package along with gopacket to parse network traffic with pretty good success. These libraries have made it much easier to work with network captures and they've definitely saved me a ton of time. I'd like to take it a step further and use the tcp assembly package to start reassembling TCP streams, but I'm not really sure from the examples provided in the docs how to go about it. The link is here: http://godoc.org/code.google.com/p/gopacket/tcpassembly/tcpreader What
