本文实例讲述了python实现的多线程端口扫描功能。分享给大家供大家参考，具体如下：

下面的程序给出了对给定的ip主机进行多线程扫描的Python代码


#!/usr/bin/env python
#encoding: utf-8
import socket, sys, thread, time
openPortNum = 0
socket.setdefaulttimeout(3)
def usage():
  print '''''Usage:
  Scan the port of one IP: python port_scan_multithread.py -o <ip>
  Scan the port of one IP: python port_scan_multithread.py -m <ip1, ip2, ip3, ip4 ...>
  '''
  print 'Exit'
  sys.exit(1)
def socket_port(ip, PORT):
  global openPortNum
  if PORT > 65535:
    print 'Port scanning beyond the port range, interrupt to scan'
    sys.exit(1)
  s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
  result = s.connect_ex((ip, PORT))
  if(result == 0):
    print ip, PORT,'is open'
    openPortNum += 1
  s.close()
def start_scan(IP):
  for port in range(0, 65535+1):
    thread.start_new_thread(socket_port, (IP, int(port)))
    time.sleep(0.006)
if __name__ == '__main__':
  t = 0
  if len(sys.argv)<2 or sys.argv[1] == '-h':
    usage()
  elif sys.argv[1] == '-o':
    ONE_IP = raw_input('Please input ip of scanning: ')
    t = time.time()
    start_scan(ONE_IP)
  elif sys.argv[1] == '-m':
    MANY_IP = raw_input('Please input many ip of scanning: ')
    IP_SEG = MANY_IP.split(',')
    t = time.time()
    for i in IP_SEG:
      start_scan(i)
  print
  print 'total open port is %s, scan used time is: %f ' % (openPortNum, time.time()-t)
