winscp | popular free SFTP and FTP client | FTP library

I have an .NET console app using WinSCP assembly version 5.19.5. The app is under impersonation in order to access files on NAS so that I set ExecutableProcessUserName and ExecutableProcessPassword for the Session object.

I my trying to connect to a client SFTP server from our Windows Server to pull the files. The connection works fine when trying from my Local machine both using WinSCP application and PowerShell script. But I have to add proxy setting while I am trying to connect from the server which is not the case in Local connection.

While in the server I am able to connect from WinSCP application by enabling proxy setting but fails when I am trying to connect using PowerShell script. I got the custom generated PowerShell script from WinSCP connection. Below is the code snippet and corresponding error message.

How can I disable the option not to open VS and Code tabs every time I open a file in VS Code?

It only occur when I open from WinSCP a file on a remote server.

As part of a larger task I want to move some files, work on them and return the new files to the sftp server. Due to restrictions laid upon me I am only able to use Python 3.4, which excludes me from any nice and fancy modules like Paramiko and pysftp.

Connection to the server fails, according to the stdout pipe the hostkey is incorrect. The returned "incorrect" key is not identical to the one that was passed to the function. It has an additional, leading backslash and is cut short. The originally passed key is "ssh-XXXXXXX 256 XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX". The "incorrect" key is "\ssh-XXXXXXX". The presumption is, that subprocess.Popen mangles the string in a way.

• hostkey, passphrase, and privatekey are all necessary
• the hostkey has been generated directly by the server and matches the fingerprint returned by the stdout pipe
• the connection works when done in a windows shell, but implementation in python is desired.
• the connection works when accepting any given Key through usage of *, but that would obviously be insecure, therefore not viable.

Code is as follows:

I use Visual Studio Code and WinSCP. When I open .scss file via WinSCP the file is opened automatically by VSC – It's ok. There is an extension Live Sass Compiler to I could compile .scss into .css file. The problem is that .css file is created in temporary folder with random number so I always must upload the file manually by drag the file from the folder to FTP client.

Is it there any solution to upload the .css file automatically on save from the temporary folder? Thank you in advance for a help.

I have an issue while connecting to a FTPS server with TLS/SSL Implicit encryption via PROXY.

I am following the custom Apache FTPS Client (commons-net-3.8.0) solution provided from Java FTPS client through HTTP proxy

My server connection is working, but unable to list or file transfer, getting below error:

425 Can't open data connection for transfer of ""

Data connection / File transfer is working fine from Windows WinSCP and Linux LFTP.

WinSCP Log:

I need to automate the upload of some files from client PCs to a central server. We're building central statistics for an online gaming community, processing game replay files.

• target is my own small VPS server running ubuntu
• upload file size 2-3MB
• 20-40 different clients running windows spread around the globe
• I expect ~6GB of wanted data to be uploaded over the course of 7 weeks (a season in our game) and 5-10x that amount of "unwanted" data.

The files are processed on the server, and then they're not required anymore, and ought to be deleted to not run out of disk space eventually. I also only need some of the files, but due to the files requiring very complex processing including decryption, so i can only determine that after the server processed it.

My initial idea was to use a scriptable client such as WinSCP, and use some Windows scheduler entry to automate it. WinSCP documentation looks very nice. I am a bit hesitant because I see the following problems:

• after deletion on the server, how to prevent re-upload ?
• ease of setup to technical novices
• reliability of the solution

I was thinking maybe someone has done the same before and can give some advice.

I have a Java server technology (Ignition by Inductive Automation specifically) that calls a batch file that is meant to use WinSCP to transfer some text files overnight to our customer. It is not working and I am not sure why.

Here is the batch file – actual information has been changed so any typos are not representative of actual batch file. Note that

I have a batch file that receives an argument then passes that argument to a text scrip file that invokes WinSCP to download a file.

My goal is to download today's file.

I am able to download the file if in the text script file I don't have >=today.

What do I need to change to download today's file, if it exists?
