Begins asynchronous ClearCommandChannel operation. Reverts the protected control connection back to plaintext connection.

Namespace:  Rebex.Net
Assembly:  Rebex.Ftp (in Rebex.Ftp.dll)

Syntax

Visual Basic
Public Function BeginClearCommandChannel ( _
	callback As AsyncCallback, _
	state As Object _
) As IAsyncResult
C#
public IAsyncResult BeginClearCommandChannel(
	AsyncCallback callback,
	Object state
)

Parameters

callback
Type: System..::..AsyncCallback
An optional asynchronous callback to be called when the operation is complete.
state
Type: System..::..Object
A user-provided object that identifies this particular asynchronous operation.

Return Value

An IAsyncResult that references the asynchronous operation.

Remarks

Implements the FTP CCC (Clear Command Channel) command.

This command is used in circumstances where it is desirable to protect the control connection only during authentication, when user credentials are being sent by the client.

When the control connection is reverted to plaintext, subsequent data transfers will be protected with the current SecureTransfers settings.

In builds for .NET 4.0 and higher, this method is available as an extension method. Add 'using Rebex.Legacy' (C#) or 'Import Rebex.Legacy' (VB.NET) to your code in order to use it.
