>
> Some FTP clients occasionally sends a invalid PORT number (PORT 0,0,0,0,0,0)
> (Tested with Python Ftplib and Windows WinInet API). The FtpServer server
> accepts the port number and starts processing the following STOR command. It
> sends 150 response. But during the call to openConnection inside
> STOR.execute( ) an exception is caught and the server responds with code 425.
> It is causing the FTP client to hang. It will perhaps be bettter if the
> server detects invalid port number and reject the STOR request with response
> 451.
