Hello people, pardon me if this has been answered before, couldn't find any trails. I have the following code:
addr = '127.0.0.1', 5050 srv = SocketServer.ThreadingTCPServer(addr, handle_con) srv.socket.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1) srv.serve_forever()
Everything is working as expected, except for the fact that the setsockopt does not do what i'd like it to. I understand it's highly possible I've passed wrong arguments but could not find any help on the right ones. What I want it to do is to be able to start a server on port 5050, even if another server was just shut down and there's still a closing listen socket there. Since it does not work, I have to wait about 30 sec between each run of my program. Any advice, please?
Thank you, Costas
The problem is that the SO_REUSEADDR socket option must be set before the address is bound to the socket. This can be done by subclassing ThreadingTCPServer and overriding the server_bind method as follows:
import SocketServer, socket class MyThreadingTCPServer(SocketServer.ThreadingTCPServer): def server_bind(self): self.socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) self.socket.bind(self.server_address)
