ftp upload ends in 0kb

a client has a problem with his ftp. This is the only client having this issue.
He is working from a macintosh computer (Cyberduck 3.2.1, MacOSX 10.4).

He can connect and create directories. Also he can upload, however the upload ends in a 0kb file.
There are no log entries.

Anyone has any experience with this situation?


Mmm, well, first off, can you verify that he’s not over quota? That’s the first thought that comes to mind.

The only other issue I can think of is that I occasionally see some issues related to FTP connection tracking come up.

In those cases, certain clients can move around the directory tree, but can’t actually upload.

To solve that, try loading the “nf_conntrack_ftp” module with:

modprobe nf_conntrack_ftp

And then have the user log in and see if they can upload.


This issue is solved in the meantime.
Apparently Mac has a build in firewall just as linux has.

He turned it off and the issue is gone.

I knew it wasn’t server related though as I could upload in his domain without issues.

thanks for the input!
