DummyAuthorizer let any user with any password in

[dge]

Hello.

I have question regarding basic_ftpd.py example. I would like it to
let any user with any password(for example setting the same folder for
each user).

For example :
user1 : passw3er login succesfull /home/ftp
user1 : passother login succesfull /home/ftp
user2 : pass3 login succesfull /home/ftp
..... ....
..... .... ....
.... ....

Is there any clean, easy way to do this(i would like to avoid listing
these users in DummyAuthorizer/and it would be nice if any user could
login with any password).

I'm aware of anonymus login, but my use case is a little bit
different.

regards
Dominik

Hi,
you can subclass DummyAuthorizer.validate_authentication() method and
make it return True:

from pyftpdlib import ftpserver

class NoAuthorizer(ftpserver.DummyAuthorizer):
def validate_authentication(self, username, password):
return True

handler = ftpserver.FTPHandler
handler.authorizer = NoAuthorizer()
server = ftpserver.FTPServer(('', 21), handler)
server.serve_forever()

Regards,

Giapaolo

Sorry, I should have replied more carefully.
You obviosuly also have to re-define all the other methods which are
involved in the login process.
This should work.

from pyftpdlib import ftpserver

class NoAuthorizer(ftpserver.DummyAuthorizer):

def get_home_dir(self, username):
return "/home/your_user"

def validate_authentication(self, username, password):
return True

def get_msg_login(self, username):
return "hello"

def get_msg_quit(self, username):
return "goodbye"

def get_perms(self, username):
r = "elr"
w = "adfmwM"
return r + w

def has_perm(self, username, perm, path=None):
return perm in self.get_perms(username)

thanks for reply. After adding the rest of methods which are involved
in login process it worked. For others interested in this topic i also
added

def impersonate_user(self,username, password):

def terminate_impersonation(self):

def has_user(self, username):
return True

Dominik
