Connecting to the XDB repository using an FTP tool, from a client machine works fine, however attempting to list the
current directory content fails and returns the message 'Error: Failed to retrieve directory listing'.

Below is an example of the debug output that can be obtained:
Status: Resolving address of host.domain.be

Status: Connecting to xxx.xxx.xxx.xx:2100...
Status: Connection established, waiting for welcome message...
Response: 220- host.domain.be
Response: Unauthorised use of this FTP server is prohibited and may be subject to civil and criminal prosecution.
Response: 220 host.domain.be FTP Server (Oracle XML DB/Oracle Database) ready.
Command: USER HEPL
Response: 331 pass required for HEPL
Command: PASS ************
Response: 230 HEPL logged in
Status: Server does not support non-ASCII characters.
Status: Connected
Status: Retrieving directory listing...
Command: CWD /test
Response: 250 CWD Command successful
Command: TYPE I
Response: 200  Type set to I.
Command: PORT nnn,nnn,nnn,nnn,nnn,nnn
Response: 200 PORT Command successful
Command: LIST
Response: 150 BIN Data Connection
Response: 550 LIST error in processing request
Error: Failed to retrieve directory listing

There is a firewall between the client and the server, and it is working perfectly when the ftp connection
is executed directly from the database server.
