Stephen and Michiel,
Thank you both for your replay.
If I chroot users in their home directories of ibays, the usernames and passwords are then send to ftp (21) in non encrypted mode.
Please correct me if I'm wrong.
But if I gave them shell access users are then able to communicate via 22 port with encrypted mode but gain access to move to the all tree.
(i tried WinSCP, winscp.sourceforge.net based on putty).
Solution will be if I could limit users to their home directories/ibays when working on port 22.
