Hi,

a script, which should send some files to a server and (if successful) move them to a "done" location, seems to work (Error Code 0) but has also a problem (Sending special code: 12) and in fact ... it doesn't work.

Since I've read some posts here and part of the documentation, I was able to solve most of my issues, but now I'm completely stuck! I think my remaining problem has something to do with the "resume" ability ...

Code:

... and I just want to turn it off! But I dont know, if I implemented the commands correctly which I've from the dokumentation. And if it was right ... whats the reason, that my uploaded file is afterwards not there? If i use the GUI, all is working nice. If I read the logs, it seemed to be nice. Here's what I've done in the according script (special interest in the transfer resume options):

Code:
param (
    $localPath = "C:\SourceFiles\*",
    $remotePath = "/in/",
    $backupPath = "C:\TransferedFiles\"
)
 
try
{
    # Load WinSCP .NET assembly
    Add-Type -Path "C:\Program Files (x86)\WinSCP\WinSCPnet.dll"
 
    # Setup session options
    $sessionOptions = New-Object WinSCP.SessionOptions
    $sessionOptions.Protocol = [WinSCP.Protocol]::Sftp
    $sessionOptions.HostName = "194.138.20.139"
    $sessionOptions.UserName = "SomeOne"
    # PASSWORT WIRD NICHT GEBRAUCHT
    # $sessionOptions.Password = ""
    $sessionOptions.SshHostKeyFingerprint = "ssh-rsa 1024 00:11:22:33:44:55:66:77:88:99:aa:bb:cc:dd:ee:ff"
    $sessionOptions.SshPrivateKeyPath = "C:\Program Files (x86)\WinSCP\SomeOnePrivateKey.ppk"
 
    $session = New-Object WinSCP.Session

    # UM LOG ZU ERZEUGEN DARF FOLGENDE ZEILE NICHT AUSGEREMT SEIN
    $session.SessionLogPath = "C:\Program Files (x86)\WinSCP\Logs\Log.txt"
 
    try
    {
        # Connect
        $session.Open($sessionOptions)

        # ResumeMode Off
        $transferOptions = New-Object WinSCP.TransferOptions
        $transferOptions.ResumeSupport.State = [WinSCP.TransferResumeSupportState]::Off
        $transferOptions.TransferMode = [WinSCP.TransferMode]::Binary
 
        # Upload files, collect results
        $transferResult = $session.PutFiles($localPath, $remotePath)
 
        # Iterate over every transfer
        foreach ($transfer in $transferResult.Transfers)
        {
            # Success or error?
            if ($transfer.Error -eq $Null)
            {
                Write-Host ("Upload of {0} succeeded, moving to backup" -f
                    $transfer.FileName)
                # Upload succeeded, move source file to backup
                Move-Item $transfer.FileName $backupPath
            }
            else
            {
                Write-Host ("Upload of {0} failed: {1}" -f
                    $transfer.FileName, $transfer.Error.Message)
            }
        }
    }
    finally
    {
        # Disconnect, clean up
        $session.Dispose()
    }
 
    exit 0
}
catch [Exception]
{
    Write-Host $_.Exception.Message
    exit 1
}


Does anebody has a clue whats wrong with my script ... or why its telling me: It has copied all and then the files are not there? The Backup Part is working ... just the transfer to the sftp is my problem!

Thx a lot

Can you see the file in the /in/ folder, when you upload it using any GUI SFTP client?

Hi Prikryl,

thx for your response, I was a bit away, but here's the answer:

Yes. If i connect manually with the GUI, navigate into the /in/ folder and upload the File (F5) it's working as supposed. Am I right with my suspect, that this could be a resume problem and how to supress the resume mechanism?

Have a nice Weekend

It's not related to resuming probably.

Add Session.ListDirectory call to the PowerShell script, enable logging and attach the log.
And attach a log showing the GUI upload.
