How can I bind user data to current ftp session?

[Michael Liao]

Hi

I find a single username cannot store enough user data.

Is there any ftp session or context that can hold current user data?

Thanks!

Here is my RemoteAuthorizer that need access user info after
authentication:

class RemoteAuthorizer():

def validate_authentication(self, username, passwd):
userinfo = get_remote_userinfo(username, passwd);
if userinfo is None:
return False
# TODO: how to bind userinfo to current ftp session?
return True

def get_home_dir(self, username):
# TODO: how to get userinfo from current ftp session?
return '/nfs/users/%s' % userinfo.id

Hi, 

I'm not sure what you mean exactly.

If you want to access the FTP session from the authorizer you just can't since in the autorizer you have no reference to the session handler (FTPHandler).

In this case you have to refactorize your code and move the logic from the authorizer to the handler.

Try to provide some more info about what you are trying to achieve exactly.

Hi

I just want to know is there a way to bind some data to current ftp session like threadlocal?

For example when I use web.py to handle an http request with multiple processors, I can bind data to web.ctx in a processor and the post processors can get data from web.ctx. A web.ctx is sth. like a threadlocal. Does pyftpdlib provides such context in an ftp session?

Thanks!

No idea what this means. What data? What do you mean by "bind"?

> ...like threadlocal

Ditto

?!?

Really, I have no clue as what you're asking, sorry.

Subclassing the AbstractedFS is probably what you want to do - you can
then store your own data on a per session basis in there.

We had a slight problem because we needed to use the data from the
authorization phase to make the new AbstractedFS.

Take a look at

https://github.com/ncw/ftp-cloudfs/blob/master/ftpcloudfs/server.py

And you'll see how we did it. Not terribly elegant!
