server

说明：刚开始接触python网络编程，使用socket编写一个简单的单线程server。socket模块提供了一个工厂函数，也被称为socket，开发者可以调用函数以生成一个套接字对象S。要想执行网络层操作，可以调用S上的方法。在客户程序中，可以调用S.connect连接到一个服务器。在服务器程序中，可以调用S.bind和S.listen等待客户程序的连接。在客户程序请求连接时，服务器程序可以调用S.accept接受请求，该方法将返回连接到客户程序的另一个套接字对象S1.在有了一个连接的套接字对象之后，就可以调用该对象的send方法传输数据，调用该对象的recv方法接收数据了。关于socket模块提供的函数和socket对象提供的方法请读者参阅python相关的技术书籍（例如《python技术手册》）。 分三步： 1.创建模块对象 2.创建模块对象的属性 3.调用模块对象的方法完成模块所想要实现的功能 【源码如下】 #import socket module #创建模块对象 from socket import * #创建模块对象的属性 serverSocket = socket(AF_INET, SOCK_STREAM) #Prepare a sever socket #调用方法绑定server监听的主机IP在端口8000上的连接 serverSocket.bind((''

How I can use variables in ftp? This is what have i done: file a.bat: set file=test ftp -s:b.txt IP file b.txt user password get %file% quit And log shows that there isn't any %file%. ftp does not understand Windows environment variables. You have to generate your script file each time like this: set file=test set ftpscript=%TEMP%\ftp.txt echo user> %ftpscript% echo password>> %ftpscript% echo get %file%>> %ftpscript% echo quit>> %ftpscript% ftp -s:%ftpscript% IP Here I have defined a temporary script in the temp directory so it does not pollute current directory. This an example for uploading

I took a game that my friend made and wanted to make it playable across browsers by sending keypress data between peers with WebRTC and websockets. However, I get this error in the console: WebSocket connection to 'ws://localhost:3000/' failed: Connection closed before receiving a handshake response My server file has the following few lines: 'use strict'; const express = require('express'); const SocketServer = require('ws').Server; const path = require('path'); const PORT = process.env.PORT || 3000; const INDEX = path.join(__dirname, 'index.html'); const server = express(); server.use

I am start working with elastic search.I successfully install elastic search on my server(Different from application server).But When I try to call Elatic search from my Application server it gives an error Fatal error: Uncaught exception 'Elasticsearch\Common\Exceptions\NoNodesAvailableException' with message 'No alive nodes found in your cluster' When I check Elastic search status it shows Active . How can I call elastic search from my Application server to my Elastic search server. <?php require 'vendor/autoload.php'; $hosts = [ 'ip_address:9200' // IP + Port ]; $client = Elasticsearch

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.bind((HOST, PORT)) s.listen(1) any_connection = False while True: try: conn, addr = s.accept() data = conn.recv(1024) any_connection = True # keep looking if not data: continue pid = os.fork() if pid == 0: server_process(data, conn) except KeyboardInterrupt: break if any_connection: print("Closing connection") conn.close() I'm catching the KeyboardInterrupt signal here on an infinite-running TCP server I wrote in Python. However, even though I know it is closing the connection because it prints Closing Connection , when I try to re-run

I am new to WebRTC. I was learned about the turn server. The below thing is used to configure the turn server works on TCP for a webrtc application. Example turn server configuration in webrtc application :- { url: ‘turn:192.158.29.39:3478?transport=tcp’, credential: ‘JZEOEt2V3Qb0y27GRntt2u2PAYA=’, username: ‘28224511:1379330808′ } The meaning for the ?transport=tcp is it works on TCP protocol like that they said. My question is, The turn server works on TCP means, it is only for establishing a connection between turn server it works on TCP or for transferring a WebRTC media via turn server it

First time asking a question here, and new to android programming. I'm following an online youtube tutorial to create a login by user "Tonikami TV". Everything is fine with the app except when it comes to the serverRequests class. I get that NameValuePair , HttpParams , etc. are deprecated which I understand to be outdated and unsupported since API 22. I've searched for some fixed or alternatives but can't really make sense of them and how I would apply them to my code. Any help would be greatly appreciated. Thanks :) @Override protected Void doInBackground(Void... params) { ArrayList

On my machine, windows 7 - Enterprise with 1 x Intel Xeon E5-1660 0 @ 3.30Ghz (6 cores/cpu with Hyper Threading activated), Environment.ProcessorCount return 12 which is exact. On a Windows Server 2012 with 2 x Intel Xeon E5-2697 v3 @ 2.60GHz (14 cores/cpu with Hyper Threading activated(I think because task manager show: 2 sockets, 28 cores, 56 logical processors)), Environment.ProcessorCount return 28 which appears to us as wrong because 2x14x2 = 56. Why on Windows Server 2012 c# method Environment.ProcessorCount does not return the proper number of logical processors? As Additional
