In the article Java Socket Chat room programming (i) the use of socket to implement chat message push we talked about how to use the socket to allow the server and the client to pass messages between the message to achieve the purpose of the push message, and then I will write out how to let the server establish client and client communication. In fact, it is to

Use socket to implement multiple connections and ssh functions, and socket to implement multiple sshI. Preface In the previous article, we already know that the client connects to the server through socket for a data transmission. How can we implement multiple data occurrences on the client? But does the server accept multiple clients?2. Send Chinese Information

After all data operations are completed, you can call the close () function to release the socket and stop any data operations on the socket:Close (sockfd ); You can also call the shutdown () function to close the socket. This function allows you to stop data transmission in a certain direction, while data transmission in one direction continues. For example, you can close the write operation of a

Socket address In Java, you can use the host name or host address to identify a network address, for example, www.baidu.com and 115.239.210.26, but the host name must be resolved to a digital address for Communication (DNS ), this process will take a certain amount of time, so we generally use a digital address in the program. In Java, inetaddress represents a network destination address, including host name and number address information. It has two

Summary of Socket-based simple chat tools (original) and socket chat tools During this time, I can't help but try to write a summary to encourage myself to study hard and write poorly. Please advise me! The following is a simple program for sending messages and files. First, the server needs to prepare two sockets and two threads as follows: // Communicate with the client private

Original://http://blog.csdn.net/linybo/article/details/51141960The sample program is a synchronous socket program, the function is very simple, just the client sends a message to the server, the server returns a message to the client, here is just a simple example, is a basic socket programming process, in the following article, The synchronization and asynchrony of sockets are recorded in turn, along with

Day8 -- socket network programming advanced, day8 -- socket Socket: socketIt is to achieve data exchange between the server and the client. The server receives and sends data, and the client sends and receives data.Python3. This is because the client needs to convert to bytecode when sending a connection to the server, and also to bytecode when the server returns

. Net socket development-synchronous socket implementation: two examples today, let's talk about the. NET network application Program Many people think that synchronous sockets should not be used in the network application server socket. Yes, this is the case in most cases, but in some scenarios, we may get more results by using synchronous

PHP socket connects to the server template, socket server. When the socket of PHP is connected to the server template, the socket server finds that some cached data needs to be accessed by external interfaces while organizing the new framework. What is more convenient is the php interface, PHP

PHP + SOCKET because the SOCKET is not connected and the address is not provided, the request for sending or receiving data is not accepted.

Here I will implement a more complete chat example and explain the logic. Because this piece of socket is larger, so I will separate a few to write

First, the socket to write the server steps:1. The first step is to create the socket object. Call the socket constructor.
