本文例項為大家分享了python實現埠掃描的具體程式碼，供大家參考，具體內容如下

今天老師上課說的內容，使用多執行緒+socket寫一個埠掃描器
寫的些許潦草，也沒註釋，不過問題不大，應該都能看懂
多執行緒+queue真的nice！！

import socket
import threading
import time
import queue
import sys

class ScannerPort(object):
 class ScanPorts (threading.Thread):
 def __init__(self,ip,portlist,timeout):
  threading.Thread.__init__(self)
  self.ip = ip
  self.portlist = portlist
  self.timeout = timeout
  
 def run(self):
  while True:
  if self.portlist.empty():
   break
  ip = self.ip
  port = self.portlist.get() 
  timeout = self.timeout
  
  try:
   s = socket.socket()
   s.settimeout(timeout)
   result = s.connect_ex((ip,port))
   if result == 0:
   sys.stdout.write("% 6d [OPEN]\n" % port)
  except Exception as e:
   print(e)
  finally:
   s.close()

def main(ip,port_list,thread_num):
 start_time = time.time()
 port_scanner = ScannerPort()
 threads = []
 port_queue = queue.Queue()
 timeout = 2
 
 for port in port_list:
 port_queue.put(port)
 
 for i in range(thread_num):
 threads.append(port_scanner.ScanPorts(ip,port_queue,timeout))

 for thread in threads:
 thread.start()
 
 for thread in threads:
 thread.join()
 
 print("耗時：",time.time() - start_time,"s")
