Upload 200KB files via WinSCP .NET assembly

2012-09-25 17:09

I am using WinSCP .NET assembly to upload files via SFTP. On uploading any files larger than 100kb, getting error messages "filepart could not be renamed to target file name, you may try to turn off transfer resume support.. In the .NET source code I added following code to disable the settings:

sessionOptions.AddRawSettings("ResumeSupport", "2")
sessionOptions.AddRawSettings("IgnorePermErrors", "1")
sessionOptions.AddRawSettings("PreserveTime", "0")

But still I am getting the same error message. While uploading it though GUI, I am not facing any issues, but using .NET assembly. I am not able to upload large files.

Rename Permission issue while uploading the file via SFTP

2013-01-09 00:46

I have downloaded 5.1.3 version of WINSCP.DLL to work with .NET. Use following code to ignore the error messages "filepart' could not be renamed to target file name. We don't have rename permission to the destination SFTP folder.

With sessionOptions
    .Protocol = Protocol.Sftp 
    .HostName = FTPAddr
    .UserName = FtpUserId
    .Password = FTPPassword
    .PortNumber = FTPPort
    .SshHostKeyFingerprint = sshHostKey 
    .AddRawSettings("ResumeSupport", "2")
    .AddRawSettings("IgnorePermErrors", "1")
    .AddRawSettings("PreserveTime", "0")
End With

Let me know, if this issue is fixed already with 5.1.3 version ?

Thank you.

It's not. Will be fixed in 5.2, as per the tracker entry above.

5.2 Release Date or Beta Release

Any idea on the release date of 5.2 or beta release? Or, a way to get around the Resume Support using the .Net assembly, Or, even a trial piece of CPP to allow local builds to resolve?
Product is still awesome!!!

Upload 200KB files via WINSCP .NET assembly

2013-04-08 23:27

I just downloaded version 5.2 and I am still seeing the same issue. File could not be renamed..
Am I disabling the resume support correctly?

SessionOptions sessionOptions = new SessionOptions()
{
    Protocol = Protocol.Sftp,
    HostName = ConfigurationManager.AppSettings["sftp.host"],
    UserName = ConfigurationManager.AppSettings["sftp.userName"],
    Password = ConfigurationManager.AppSettings["sftp.password"],
    SshHostKeyFingerprint = ConfigurationManager.AppSettings["sftp.SshHostKeyFingerprint"],
};
       
sessionOptions.AddRawSettings("ResumeSupport", "2");
sessionOptions.AddRawSettings("IgnorePermErrors", "1");
sessionOptions.AddRawSettings("PreserveTime", "0");

Thanks Henry

@hjackows: No you are not. Use:

TransferOptions.ResumeSupport = TransferResumeSupport.Off

@martin: Hi, I've just tried this I'm getting a message that the ResumeSupport property is readonly. Can you help? Full code:

Dim sftp As New SessionOptions
Dim session As New Session
Dim transfer As New TransferOptions
Dim result As TransferOperationResult
 
With sftp
    .Protocol = Protocol.Sftp
    .HostName = "***"
    .UserName = "***"
    .Password = "***"
    .SshHostKeyFingerprint = "***"
End With
 
session.Open(sftp)
transfer.ResumeSupport = TransferResumeSupport.Off  [property is readonly]
transfer.TransferMode = TransferMode.Binary
result = session.PutFiles("C:\xx.csv", "xx.csv", False, transfer)
result.Check()

Thank you.

Don't worry, fixed it myself:

transfer.ResumeSupport.State = TransferResumeSupportState.Off

transferOptions.ResumeSupport.State = TransferResumeSupportState.Off;
