python使用多线程+socket实现端口扫描

本文实例为大家分享了python实现端口扫描的具体代码，供大家参考，具体内容如下

今天老师上课说的内容，使用多线程+socket写一个端口扫描器
写的些许潦草，也没注释，不过问题不大，应该都能看懂
多线程+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("耗时：", time.time() - start_time, "s")
