14     return ip[0] <<24 | ip[1]<<16 | ip[2]<<8 |ip[3]
15 def num2ip(num):
16     return '%s.%s.%s.%s' %( (num & 0xff000000) >>24,

22 def get_ip(ip):
23     start,end = [ip2num(x) for x in ip.split('-') ]
24     return [ num2ip(num) for num in range(start,end+1) if num & 0xff ]
25     
26     
27 def scan(ip,port):
28

31         server = telnetlib.Telnet() # 創建一個Telnet對象
32         
33         server.open(ip,port)         # 利用Telnet對象的open方法來創建TCP連接測試端口是否開放
34

42         print(e)
43     
44     
45 if __name__ == '__main__':
46     iplist = get_ip('10.10.10.1-10.10.10.10')
47     print(iplist)
48     
49     portlist=['22','80']
50     starttime = time.time()
51     
52     #單線程模式
53     '''
54     for port in portlist:
55         for ip in iplist:
56             print(scan(ip,port))
57     '''
58     
59     #協程模式，多並發
60     #下面這句的意思就是循環portlist列表里面的port,循環iplist列表里面的ip，全部加到協程(gevent)里面，一起並發啟動執行
61     threads = [gevent.spawn(scan, ip,port) for ip in iplist for port in portlist]
62     gevent.joinall(threads)
63     
64     endtime = time.time()
65     print('一共運行了{0}秒'.format((endtime-starttime)))
