server=SocketServer.ForkingTCPServer(('127.0.0.1',8009),MyRequestHandler) SocketServer的ThreadingTCPServer之所以可以同时处理请求得益于select和os.fork两个东西,其实本质上就是在服务器端为每一个客户端创建一个进程,用于后续数据处理,当前新创建的进程用来处理对应客户端的请求,所以,可以支持同时n个客户端链接(...
The “readable” sockets represent three possible cases. If the socket is the main “server” socket, the one being used to listen for connections, then the “readable” condition means it is ready to accept another incoming connection. In addition to adding the new connection to the list of...
pythonday7总结(socket网络编程和paramiko) 1.socket网络编程 1)socket概述:通常称为套接字,用于描述IP地址和端口,是一个通信链的句柄,应用程序通常通过套接字向网络发出请求或者应答网络请求。说白了就是一种通信机制。 2)socket服务端步骤: 打开一个socket,绑定一个地址和端口,ip一般设置无论从我这个机器的哪个...
client = paramiko.SSHClient() 首先创建一个 SSHClient 的实例,这个 client 是 paramiko 对外暴露的最上层的一个 API,方便我们调用各种方法。 client.connect(...) 通过该方法与远端设备建立连接,该方法接受的参数很多,这里不对其展开讲解。 2.1 调用该方法后,会首先创建一个四层的socket连接; ...

建立一个socket必须至少有2端, 一个服务端,一个客户端, 服务端被动等待并接收请求,客户端主动发起请求, 连接建立之后,双方可以互发数据。 Anetwork socketis an endpoint of a connection across acomputer network. Today, most communication between computers is based on theInternet Protocol; therefore most ne...
