26 
27 def scan(ip,port):
28     
29     try:
30         #server = telnetlib.Telnet(ip, port, timeout=10)
31         server = telnetlib.Telnet() # 创建一个Telnet对象
32         
33         server.open(ip,port)         # 利用Telnet对象的open方法来创建TCP连接测试端口是否开放
34         
35         #a表示以追加的形式将端口开放的ip列出来
36         file = open('thefile.txt', 'a')
37         file.write(ip+" "+port+"\n")

12 def ip2num(ip):
13     ip=[int(x) for x in ip.split('.')]
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,

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     
29     try:
30         #server = telnetlib.Telnet(ip, port, timeout=10)
31         server = telnetlib.Telnet() # 创建一个Telnet对象
32         
33         server.open(ip,port)         # 利用Telnet对象的open方法来创建TCP连接测试端口是否开放
34         
35         #a表示以追加的形式将端口开放的ip列出来
36         file = open('thefile.txt', 'a')
37         file.write(ip+" "+port+"\n")
38         file.close()
39         print('{0} port {1} is open'.format(ip, port))
40     except Exception as e:

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     #单线程模式
53     '''
54     for port in portlist:
55         for ip in iplist:

57     '''
58     
59     #协程模式，多并发
60     #下面这句的意思就是循环portlist列表里面的port,循环iplist列表里面的ip，全部加到协程(gevent)里面，一起并发启动执行
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('一共运行了{0}秒'.format((endtime-starttime)))
