Solve the socket. Error: [errno 98] address already in use problem

If the address bound to the socket in python is in use, errors may occur,

In Linux:

"Socket. Error: [errno 98] address already in use" is displayed"

In Windows:

"Socket. Error: [errno 10048] is displayed. Generally, each socket address (Protocol/network address/port) can be used only once"

This is because the socket does not support address multiplexing by default. If you want to reuse the socket, You need to display the settings, that is, call the setsockop function t before binding to allow the socket to reuse the address: socket.Setsockopt (socket. sol_socket, socket. so_reuseaddr, 1)

For example:

Self. recsocket = socket. socket (socket. af_inet, socket. sock_dgram) self. recsocket. setTimeout (check_timeout) self. recsocket. setsockopt (socket. sol_socket, socket. so_reuseaddr, 1) self. recsocket. BIND ('', udp_port ))
