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)

运行效果图
