Question
I want to built a simple FTP server in python which will serve the client in just downloading a text file. Can any one kindly help me by suggesting the best study material to refer and help me finding some code snippets.
Solution
Check out the FTP examples with twisted
Also a simple implementation: ftpdrop.py
OTHER TIPS
I can recommend pyftpdlib hosted at Google Code
Example:
>>> from pyftpdlib.authorizers import DummyAuthorizer
>>> from pyftpdlib.handlers import FTPHandler
>>> from pyftpdlib.servers import FTPServer
>>>
>>> authorizer = DummyAuthorizer()
>>> authorizer.add_user("user", "12345", "/home/giampaolo", perm="elradfmw")
>>> authorizer.add_anonymous("/home/nobody")
>>>
>>> handler = FTPHandler
>>> handler.authorizer = authorizer
>>>
>>> server = FTPServer(("127.0.0.1", 21), handler)
>>> server.serve_forever()

[I 13-02-19 10:55:42] poller: <class 'pyftpdlib.ioloop.Epoll'>

[I 13-02-19 10:55:42] use sendfile(2): True
[I 13-02-19 10:55:45] 127.0.0.1:34178-[] FTP session opened (connect)
[I 13-02-19 10:55:48] 127.0.0.1:34178-[user] USER 'user' logged in.
[I 13-02-19 10:56:27] 127.0.0.1:34179-[user] RETR /home/giampaolo/.vimrc completed=1 bytes=1700 seconds=0.001
[I 13-02-19 10:56:39] 127.0.0.1:34179-[user] FTP session closed (disconnect).
This is probably the best you can find to understand the FTP protocol. Implementation should be pretty simple once you've understood the mechanism.
