SetPermissions Error Statuscode 4

Sep 11 '15 at 08:37

Hi Chilkat,

I am uploading files, then setting trying to set permissions to the file, but getting an error.

Code: 
        success = sftp.SetPermissions("foldername/test1.txt", False, 777)
        If (success <> True) Then
            Console.WriteLine(sftp.LastErrorText)
            sb_LogDebug(sftp.LastErrorText)
            Exit Sub
        End If

Using Chilkat 9.5.0.51
The details of the log are below:

I found this reference about SFTP status codes on the web: https://winscp.net/eng/docs/sftp_codes

"Unfortunately, OpenSSH SFTP server uses always description “Failure”. Is such case, there is unfortunately no way to tell a reason of the failure."

Answer

I suspect the error is from an invalid permissions value (i.e. the bit flags may make no sense). You're passing decimal 777 in this code:

Code: 
        success = sftp.SetPermissions("foldername/test1.txt", False, 777)
        If (success <> True) Then
            Console.WriteLine(sftp.LastErrorText)
            sb_LogDebug(sftp.LastErrorText)
            Exit Sub
        End If

The correction is to specify the permissions using the octal literal representation in the programming language you are using. For example, it might be this:

Code: 
        success = sftp.SetPermissions("foldername/test1.txt", False, 0777)
        If (success <> True) Then
            Console.WriteLine(sftp.LastErrorText)
            sb_LogDebug(sftp.LastErrorText)
            Exit Sub
        End If
