When a client establish the connection, it returns a new socket object using the accept() function. Now, we have a socket object from accept() function. It is important to recall that the socket that we will use to communicate must be distinct from the listening socket that the server is using to accept new connections. The accept() function accepts a connect request from a TCP client socket. It returns a socket that is connected to the client and this connected socket is used for the communication between the client and server. The example server program in Python accepts connections from clients and serves them the current server time.
Apr 22, 2010 · If no timeout is specified, the global socket timeout value will be used, which by default is infinite. The above code will catch almost every timeout, but the problem is that you might still get a timeout raised as a totally different exception: 调 用accept方法时，socket会时入“waiting”状态。客户请求连接时，方法建立连接并返回服务器。accept方法返回一个含有两个元素的 元组(connection,address)。第一个元素connection是新的socket对象，服务器必须通过它与客户通信；第二个元素 address是客户的Internet地址。 5. When the accept completes the socket retrieved from the completion key by our worker thread is the listening socket, since that's the device that's associated with the IO Completion Port and generating the completion packet for the accept. We require the accepted socket as well, so we store that in the IO buffer's user data slot. Jul 20, 2010 · The call is returning immediately because you've set the socket to NON-BLOCKING. Using a timeout with a non-blocking socket makes no sense. If you want timed reads/writes, just configure the timeouts and go. Having said that, this options are not really reliable.

Python Socket Server. A socket is an endpoint to send or receive data hence we need a server and a client socket program for this purpose. A server can be created using the module socket.
