Re: Session.Open(Sessionoptions) getting error

i am getting error.

Would you mind telling us, what error is that?

Even better, start a new topic and attach a full session log file showing the problem (using the latest version of WinSCP).

To generate log file, set Session.SessionLogPath. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

I do not know how to help you. Are you able to connect from GUI? It seems like your username/password is wrong or the account is disabled.

Tryingto create Session log but it is not doing anything...

Although through GUI, it is creating the session log.
What I am missing..

$session = New-Object WinSCP.Session


$session.DebugLogPath = $WinSCPDebugLogFile
$session.SessionLogPath = $WinSCPSessionLogFile
$session.XMLLogPath = $WinSCPXMLLogFile

Re: Should I use IP address instead of site address

You may want to check that you should be using FTP Secure and not SFTP
and if it is FTPS, is TLS the proper security?

I Did. The issue I was having was in setting the SslHostCertificateFingerprint print.
Here is my Powershell code for connecting.

I got the value for the finger print by connecting to the site using the gui,going to the commands menu and choosing "Server/Protocol info"
Hope this helps.

FTPS Explicit TLS .NET Libarary

Edit: Sorry, user error. I was not setting the SSLHostCertificateFingerPrint before connecting.

Sorry for the rogue posting.

John



Hello, I'm having an issue connecting to a FTPS site using Explicit TLS encryption through the .Net Library through Powershell.
This is a new problem and first time I've tried using FTPS with Explicit TLS. WHen I use the GUI interface, I am able to connect.
When I go through the powershell code, I get an unable to connect exception.
Here is my code: 

    $winSCPathDLL = $global:appSettings["WinSCPDLL"]

    $winSCPDLLPath = $winSCPath + $winSCPathDLL

    [Reflection.Assembly]::LoadFrom($winSCPDLLPATH) #| Out-Null



   # Setup session options

   $sessionOptions = New-Object WinSCP.SessionOptions

   $sessionOptions.Protocol = [WinSCP.Protocol]::ftp

    $sessionOptions.FtpMode = [WinSCP.FtpMode]::passive

    $sessionOptions.FtpSecure = [WinSCP.FtpSecure]::explicittls

   $sessionOptions.HostName = $global:appSettings["FTPHost"]

   $sessionOptions.PortNumber = $global:appSettings["FTPPortNumber"]

   $sessionOptions.UserName = $global:appSettings["FTPUser"]

   $sessionOptions.Password = $global:appSettings["FTPPassword"]



   $session = New-Object WinSCP.Session



        $transferOptions = New-Object WinSCP.TransferOptions

        $transferOptions.TransferMode = [WinSCP.TransferMode]::Binary



   $session.Open($sessionOptions)  #<<< Exception throw here


When I load the assembly, I get this:
GAC Version Location
--- ------- --------
False v2.0.50727 D:\ServiceOrders\Script\WinSCP\WinSCPnet.dll

I downloaded the latest .Net DLL today, so I have version 5.5.1.0

The exception details I can get to :
Connection failed.
At D:\Script.ps1:167 char:3
+ $session.Open($sessionOptions)
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [], SessionRemoteException
+ FullyQualifiedErrorId : SessionRemoteException


I'm sure I must be missing something, but I am at a loss for finding it.

Thank you for the help.

John
