Introduction
Socket errors refer to errors caused by various reasons when using Socket for network communication. Socket is a network programming interface that allows applications to communicate over the network through the TCP/IP protocol or the UDP protocol. During network communication, various errors may occur, such as connection timeout, connection reset, failure to connect, etc. These errors are called Socket errors.
wrong reason
Socket errors are usually caused by aspects such as the operating system or network equipment, and may include some of the following reasons:
- Connection timeout: When establishing a connection, the waiting time for the other party's response exceeds the specified time, resulting in a connection failure.
- Connection reset: After the connection is successfully established, the connection is closed abnormally due to reasons such as network equipment or the other host, resulting in a connection failure.
- Network unreachable: During network communication, it is found that the network is unreachable and communication cannot be performed.
- Connection rejected: The other host rejects the connection request, resulting in a connection failure.
- Address already in use: During network communication, the requested address is already occupied by other applications, resulting in connection failure.
Summarize
When a Socket error occurs, it is usually necessary to debug and handle it according to the specific error information, such as modifying the network configuration, increasing the connection timeout, checking the network connection, and so on. Correct handling of Socket errors can effectively improve the stability and reliability of network communication.
