acknowledgement.(1) Server monitoring: Is the server end socket does not locate the specific client socket, but in the status of waiting for the connection, real-time monitoring network status.(2) Client request: Refers to the client's socket to make a connection request, to connect to the target is the server-side socket. To do this, the client's socket must fi

authentication communication services, SSL/TLS. Sockets is actually a file descriptor. Unlike local files, Sockets connects to a file on the network. 1. create a UDP local connection: #!/usr/bin/env pythonimport socket, syss = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)MAX = 65535PORT = 1060if sys.argv[1:] == ['server']: s.bind(('127.0.0.1', PORT)) print 'Listening at', s.getsockname() while

Python socket programming (write server instance) + difference and use of send and sendall, programming introduction sendall To compile a server in python, follow these steps: 1. The first step is to create a socket object. Call the socket constructor. For example: Socket = socket. socket (family, type) The family para

Use SocketServer in Python to implement non-blocking communication between the client and the server. The SocketServer module is used to implement non-blocking communication between the network client and the server.First, let's take a look at the classes available for use in the SocketServer module:BaseServer: contains the core functions of the server and hooks

The Socketserver module is used to realize network client-server concurrent connection non-blocking communication.First, let's look at the classes available in the next Socketserver module:Baseserver: The core functionality of the containing server is linked to the hybrid (Mix-in) class, and this class is used only for derivation, so instances of this class are not generated; Consider using TCPServer and ud

AF_INET, and socket_type is SOCK_STREAM or SOCK_DGRAM. protocol is usually omitted. The default value is 0. Therefore, to create a TCP/IP socket, you can use the following method to call socket. socket (). tcpSock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) Create a UDP/IP socket and call the following method: udpSock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) Create a TCP Server The proces

The previous days have been doing the company's DNS scheduler, but due to poor performance, the scheme was eventually discarded. 2.5 months of painstaking efforts, do not want to waste, so changed, the trade secret related parts removed, became a public DNS server. In fact, the simple point, is a can do DNS resolution and reply to the program (nonsense, DNS server is not to do this). function is relatively

SocketserverPython Road "Nineth": Python Foundation the Socket module is a single process and can only accept connections and requests from one client, and only when the client is disconnected can it accept connections and requests from other clients. Of course, we can also use the multi-threading module of Python to write a socket that can receive multiple client connections and requests at the same time.

socket is closed, the port number that the local side uses for the socket can be reused immediately. In general, it can be reused only after the system has been defined for a period of time. Boolean integer In this section, we use the SO_REUSEADDR option when studying, specifically:S.setsockopt (socket. Sol_socket,socket. so_reuseaddr,1) Here value is set to 1, which means that the SO_REUSEADDR is marked as true, and the operating system releases the port of the
