Python多线程端口扫描实现与示例

#coding:utf-8
import socket
import thread
import time
socket.setdefaulttimeout(3)

def socket_port(ip,port):
  try:
   if port>=65535:
     print(u"端口扫描结束!")
   s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)#创建套接字
   result=s.connect_ex((ip,port))#链接端口
   if(result==0):
     print ip,u" : ",port,u"端口开发"
   s.close()
  except:
   print(ip,":",port)
   print(u"端口扫描异常")


def IP_port(data):
  try:
   ip="127.0.0.1"
   t=time.time()
   for i in range(0,1000+1):
     thread.start_new_thread(socket_port,(ip,int(i)))#多线程扫描端口
     time.sleep(0.003)
   print(u"扫描端口完成用时:time_:%s"%(time.time()-t))


  except Exception as e:
   print(e)
   print(ip,i)
   print(u"端口扫描异常")

if __name__ == '__main__':
  print u"开始工作"
  # socket_port("127.0.0.1",135)
  IP_port("127.0.0.1")
