How to prevent CWD?

Hi ..

I have a VB6 question.

I have made a script that prevent unwanted dirs to be uploaded. I'm exiting my program and leave 1 ... This BLOCKS the PRE-MKD event, so far so god. BUT ( why are there always a but ? ) then ioFTPD or the client wants to CWD ( change owner dir ) to the NOT made "MKD" dir. And while searching it ioFTPD finally times out .. ( the unwanted dir however is NOT uploaded and all the other files is uploaded after the timeout and reconnet ).

The Question: How does i prevent the CWD to the unexisting, blocked dir ?

Do u send a '550 MKD failed' reply to the client? If u exit your script with -1, u have to return an error to the client yourself, as ioFTPD will abort it's own procedure.

Thanx for the help!

It does work now

..

But i used "226 Closing data connection." and "426 connection closed; transfer aborted." in a combination ... that worked too.

Except 226 and 426 aren't allowed response to a MKD according to the RFC.
