3.2.4.23 Application Requests Testing Transport Layer Connection

  • Article

The client MUST have an established SMB connection and MUST have performed an SMB Protocol negotiation. No SMB session is necessary.

The application MUST provide:

  • The Client.Connection that identifies the connection on which to send the request.

  • The number of responses that the application designates to receive from the server. This number SHOULD be greater than zero.

  • A block of data, which might be random, to be echoed by the server.

The client MUST construct an SMB_COM_ECHO request message as defined in section 2.2.4.39.1. The data block provided by the application MUST be sent in the SMB_Data.Bytes.Data field; otherwise, the field MUST be empty.

The request MUST be sent to the server as described in section 3.2.4.1.
