Solutions please?

I am trying to upload a large file to FTP site. I want to resume the file transfer whenever interruptions occurs in connections. Here is my code.
I am trying to resumes the file transfer by manually closing the connection but file is uploading irrespective of connection breaks

Public Function UploadFile(ByVal LocalPath As String, ByVal RemotePath As String) As Boolean
Return UploadFile(LocalPath, RemotePath, True)
End Function

Public Function UploadFile(ByVal LocalPath As String, ByVal RemotePath As String, resumeFileUpload As Boolean) As Boolean
'uploads files to FTP Directory
Dim myUri As New Uri(RemotePath.Replace("\", "/"))
Dim TargetPath As String = GetTargetPath(RemotePath, True)
Dim result As Boolean = False

Using session As New Session
session.Open(GetSessionOptions(myUri))

' Upload files
Dim transferResult As TransferOperationResult
transferResult = session.PutFiles(LocalPath, TargetPath, False, Me.GetTransferOptions(resumeFileUpload))

' Throw on any error
transferResult.Check()
If transferResult.IsSuccess Then
result = True
End If

' Display results
Dim transfer As TransferEventArgs
For Each transfer In transferResult.Transfers
Console.WriteLine("Upload of " & transfer.FileName & " succeeded")
Next
End Using

Return result
End Function

Protected Function GetSessionOptions(ByVal Uri As Uri) As SessionOptions
Dim sessionOptions As New SessionOptions
With sessionOptions
.Protocol = Protocol.Ftp
.UserName = Me.Credentials.UserName
.Password = Me.Credentials.Password
.HostName = Uri.Host
.PortNumber = Uri.Port
If Me.EnableSsl Then
.FtpSecure = FtpSecure.Explicit
End If
End With

Return sessionOptions
End Function

Private Function GetTransferOptions(resumeFileUpload As Boolean) As TransferOptions
Dim myTransferOptions As New TransferOptions

If resumeFileUpload Then
myTransferOptions.ResumeSupport.State = TransferResumeSupportState.On
myTransferOptions.OverwriteMode = OverwriteMode.Resume
Else
myTransferOptions.OverwriteMode = OverwriteMode.Overwrite
End If

myTransferOptions.TransferMode = TransferMode.Binary

Return myTransferOptions
End Function

This issue has been added to tracker.

Turns out that the other server was using some kind of intrusion detection software, and causing the drops.

You may first check the log file to see whether it indicates why the server closes the connection.

I am trying restarts, but having all kinds of problems. I run this as a Win32 process, and try to rename the logs with a date time but it continues to put the info into the same log file.

Then on subsequent tries, it says that a partial file exist and then quits.

Thanks. But please, first of all, upgrade to the latest release. Log file from 3.7.6 would be useless.

Can you post a log file? Also what version of WinSCP are you using?

I have this same problem with connection "reset by peer". WinSCP never recovers with a new successful login.

Don't get me wrong, I think this is a great program myself and my hat is off to the developers/contributors. I would even contribute financially to this project, if someone could prove that this program will work.

I am an expatriate working outside the US, and I want to download video from my home where I legally record the video on a PC. However, I also know that if that content is not secured I would be creating a problem for everyone that uses content legally (pays for it). However, I can't find any "reliable" way to move the content between the PC's which can go unattended for days at a time. This software is/was my best hope.

Please post/inform me if this situation changes. I would actually like to see the "reconnect" feature get some parameters that are adjustable, and possibly even get some logging data on just the feature, so that I could see when ISPs might be "breaking" or "resetting" the connection, and how often.

Best regards,

BitBanger

thanks for the feedback on this problem that MANY people are having.

:roll:

I have the same problem it is MAJOR ONE. I get an email: connection reset by peer.
Screen saver activates: connection reset by peer. Monitor switches off to save power: connection reset by peer.

It is close to impossible to upload large files with the program. :evil: :evil: :evil: :evil: :evil: :evil: :evil:

Is it possible to automatically reconnect / exit if there is any network failure for few seconds?
What is the commandline option in WinScp 3.8 to automatically reconnect if there is a network failure for few seconds?

I have this same problem. Auto-reconnect does nothing to fix the issue. It is extremely irritating when dealing with very large files and a slow upload.

I don't understand how to fix the problem.

No. It's enabled by default. You can disable it from GUI only.

Thanks for your reply.

I am not using the UI to do transfer of files.

Is there a scripting command to enable or disable automatic reconnection without causing any prompt?

Automatic reconnection works only, it the connection is dropped in the middle of file transfer. It should be enabled by default.

WinSCP 3.8 can reconnect broken connections so you can upload your opened file.

First to tell: I really like WinSCP and also would like to use it with Linux-Machines.

But there's still one heavy downer for this joy working with this tool:

I'm having a connection, that's somewhat unstable and found no way to fix it.
It's just only minimal discontinuity, that will not be registered with other software or connections, but that's disrupting the ssh.

If I so - like I do several times - had opened some files to work with on my server, all my work is broken, since there's no way of continuing, while the connection is long present again: it was just broken for maybe some millisecond.

So then I have to closed each editing-window, I was working with, discard the work, I done within them and start over again.

This is happening about all 5 minutes, and thus a good deal of my working is resumig such broken connections within WinSCP.

Isn't there a smarter way of dealing with broken connections, saving the work that's done in editing windows and resume them, best automatically ?

I just appreciate any helpful hint on this vexatious issue - while in any other regard I really like the use of your tool.
