Question:

SFTP VB .NET 2.0 - Trying to resume an upload without being asked

Nov 27 '12 at 08:05

Hi,

I have the following error log

ChilkatLog:
  UploadFile:
    DllDate: Aug  5 2012
    UnlockPrefix: -Removed for security-
    Username: XXXX:operator
    Architecture: Little Endian; 32-bit
    Language: .NET 2.0
    VerboseLogging: 0
    SshVersion: SSH-2.0-SSHD
    SftpVersion: 3
    handle: 30
    fromPath: C:\XXXX\20121127_full.XML
    uploadFile:
      handle: 30
      fromLocalPath: C:\XXXX\20121127_full.XML

      Socket send idle timeout
      Error sending data
      Failed to send packet in SFTP file upload.
      ResumeInfo: Can resume

      totalNumBytesSent: 192000
      uploadFileSuccess: 0
    --uploadFile
    Failed.
  --UploadFile
--ChilkatLog

Which I got after calling the follow CV.NET code:

Dim handle As String
handle = sftp.OpenFile("/YYYY/" & filename, "writeOnly", "createTruncate")
success = sftp.UploadFile(handle, "C:\XXXX\" & filename)

I'm just using UploadFile but getting an error about resuming which the client's server doesn't support and is causing errors in the process, how do I go about disabling resuming so it doesn't even try and cause issues ?

Thank in advance

Answer

The "ResumeInfo" lines in the LastErrorText do not mean that the upload was being resumed. It's purely informational saying that the upload failed, and it could possibly be resumed by your application, if your application desired, and that it would need a new connection to do it.
