Description

When I upload a file that already exists and "canOverride" is False it still uploads and overwrites the existing file.

I use:

            Using myFile As System.IO.Stream = System.IO.File.OpenRead("c:\test.txt")
                SSH_sFTPclient.UploadFile(myFile, "test.txt", False)
            End Using

As far as I know the problem only occurs on one sftp-server, which identifies itself as "SSH-2.0-CerberusFTPServer_12.0"

Research direction

Start at the SftpClient.UploadFile entry point and reproduce the case with an existing remote file, canOverride=False, and the CerberusFTPServer_12.0 server. Compare the observed behavior with another SFTP server if available; done means an existing file is not overwritten when canOverride is false.
