550 PROT P required

#1 Post by Nomad » 2006-05-04 16:45

Hi,

I have an FTPS server I am trying to connect to that fails with the error "Error: Could not retrieve directory listing". Attached below is the copy of the log (with the address and user names changed to protect the semi-innocent).

It appears that the command PROT P needs to be issued by the client in order to complete the transaction. If I right click in the Message Log window and issue the PROT P command directly then the sessions are successful (see second log attached below).

My question is this: how do I get FileZilla 2.2.10 to issue the PROT P command without having to manually do so? What configuration option am I missing?

Just FYI: The FTP server is FileZilla 0.9.16c

Thanks in advance,

Nomad
