:wink: 使用pyftpdlib 时发生错误

nmweizi

环境  python 2.7   pyftpdlib 0.7.0  ubuntu 12.04
执行python ftps-server.py

用 python 2.7 带的ftplib就可以
In [1]: from ftplib import FTP_TLS

In [2]: ftps = FTP_TLS('127.0.0.1','user','bbbb')

error_perm: 530 Authentication failed.

使用lftp 登录  ftps时提示错误
lftp ftps://fa:aa@127.0.0.1:21

lftp fa@127.0.0.1:~> ls
ls: Fatal error: gnutls_handshake: A TLS packet with unexpected length was received.
大家帮忙看看什么原因了？




















ftps_server.py代码如下：

1. from pyftpdlib import ftpserver
   
2. from pyftpdlib.contrib.handlers import TLS_FTPHandler,FTPHandler
   
3. import md5
   
4. 
   
5. 
   
6. 
   
7. class MyHandler(TLS_FTPHandler):
   
8. 
   
9.     def on_login(self, username):
   
10.         # do something when user login
    
11.         print 'username:%s' % username
    
12.        
    
13.         def on_login_failed(self, username, password):
    
14.                 print 'afasfd-----------------------------------'
    
15.                 print 'password:%s' % password
    
16. 
    
17.     def on_logout(self, username):
    
18.         # do something when user logs out
    
19.         pass
    
20.         
    
21.     def on_file_sent(self, file):
    
22.         # do something when a file has been sent
    
23.         pass
    
24. 
    
25.     def on_file_received(self, file):
    
26.         # do something when a file has been received
    
27.         pass
    
28.             
    
29.     def on_incomplete_file_sent(self, file):
    
30.         # do something when a file is partially sent
    
31.         pass
    
32. 
    
33.     def on_incomplete_file_received(self, file):
    
34.         # remove partially uploaded files
    
35.         pass
    
36.                
    
37.                
    
38. 
    
39. 
    
40. authorizer = ftpserver.DummyAuthorizer()
    
41. authorizer.add_user('user', '12345', '.', perm='elradfmw')
    
42. 
    
43. 
    
44. #authorizer.add_anonymous('.')
    
45. handler = MyHandler
    
46. handler.certfile = 'keycert.pem'
    
47. 
    
48. handler.authorizer = authorizer
    
49.     # requires SSL for both control and data channel
    
50.     #handler.tls_control_required = True
    
51.     #handler.tls_data_required = True
    
52. ftpd1 = ftpserver.FTPServer(('127.0.0.1', 21), handler)
    
53. 
    
54. ftpd1.serve_forever()
