如何让服务器侦听多个端口

Question

我想用同一台服务器监听100个不同的TCP端口.这是我目前正在做的事情: -

import socket
import select

def main():

    server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

    for i in range(1000,1100):
        server_socket.bind(('127.0.0.1', i))
    server_socket.listen(1)

    read_list = [server_socket]
    while True:
        readable, writable, exceptional = select.select(read_list, [], read_list)
        for s in readable:
            if s is server_socket:
                #print "client connected"
                client_socket, address = server_socket.accept()
                read_list.append(client_socket)
            else:
                # One of the tcp clients
                data = s.recv(1024)
                if not result:
                    s.close()
                    read_list.remove(s)
                    #print "client disconnected"

if __name__ == "__main__":
    main()

它返回错误说Permission Denied.是因为某些端口(1000-1100)是保留的并且未分配给它或由于其他原因？

我试过(8000-8100),它说 Invalid Arguments

EDITED

import socket
import select

def create_socket(TCP_PORT):
    server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
    server_socket.bind(('127.0.0.1', TCP_PORT))
    server_socket.listen(1)

    return server_socket


def main():

    read_list = []

    for TCP_PORT in range(8000,8100):
        read_list.append(create_socket(TCP_PORT))

    while True:
        readable, writable, exceptional = select.select(read_list, [], read_list)
        for s in readable:
            if s is server_socket:
                #print "client connected"
                client_socket, address = server_socket.accept()
                read_list.append(client_socket)
            else:
                # One of the tcp clients
                data = s.recv(1024)
                if not result:
                    s.close()
                    read_list.remove(s)
                    #print "client disconnected"

if __name__ == "__main__":
    main()

有两个问题.

1. 低于1024的端口是保留的.(您需要特殊权限,例如绑定到此类端口的root权限).

2. 套接字只能在一个端口侦听.因此,要监听多个端口,您需要为每个端口创建一个套接字.
