Dim instance As FtpClient
Dim value As Boolean
 
instance.PassiveTransfer = value
 
value = instance.PassiveTransfer

public bool PassiveTransfer {get; set;}

Property Value

If set to true, the PASV command will be sent to the FTP server rather than the PORT command resulting in the FTP server "listening" on a data port (other than its default) and waiting for a data connection to be established by the FTP client. If set to false, the PORT command will be sent and the FTP client will be listening for an incoming data connection. The FTP server will establish the data connection upon receipt of a transfer command.

The reply to the PASV command includes the host and port address the FTP server is listening on.

If you are having issues connecting or sending and receiving files to and from a server, try setting the PassiveTransfer property to true.

This property is the equivalent of the PassiveMode property of the ActiveX version of the Xceed FTP Library.

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
