pyftpdlib: RFC-959 asynchronous FTP server.
pyftpdlib implements a fully functioning asynchronous FTP server as
defined in RFC-959. A hierarchy of classes outlined below implement
the backend functionality for the FTPd:
[pyftpdlib.ftpservers.FTPServer]
accepts connections and dispatches them to a handler
[pyftpdlib.handlers.FTPHandler]
a class representing the server-protocol-interpreter
(server-PI, see RFC-959). Each time a new connection occurs
FTPServer will create a new FTPHandler instance to handle the
current PI session.
[pyftpdlib.handlers.ActiveDTP]
[pyftpdlib.handlers.PassiveDTP]
base classes for active/passive-DTP backends.
[pyftpdlib.handlers.DTPHandler]
this class handles processing of data transfer operations (server-DTP,
see RFC-959).
[pyftpdlib.authorizers.DummyAuthorizer]
an "authorizer" is a class handling FTPd authentications and
permissions. It is used inside FTPHandler class to verify user
passwords, to get user's home directory and to get permissions
when a filesystem read/write occurs. "DummyAuthorizer" is the
base authorizer class providing a platform independent interface
for managing virtual users.
[pyftpdlib.filesystems.AbstractedFS]
class used to interact with the file system, providing a high level,
cross-platform interface compatible with both Windows and UNIX style
filesystems.
Usage 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="elradfmwMT")
>>> 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] >>> starting FTP server on 127.0.0.1:21 <<<
