Contents:.SFTP PeculiaritiesSFTP ( Secret File Transfer Protocol, Secure FTP or SSH FTP) is the extension of SSH protocol, being a standard in the world of UNIX/Linux systems. From the user point of view, it is similar to FTP, but in fact, it is a completely different protocol, having nothing in common with FTP. Data are transferred between a client and a server through the SSH tunnel using Port 22.The main advantages of SFTP:.

Files and commands are transferred inside a secure SSH session. One connection is used to transfer both files and commands. Symbolic links, interrupt/resume transfer, file delete functions, etc. Are supported. As a rule, in channels where FTP is slow or failing, SFTP connection is faster and more reliable.

Possibility of authenticate using SSH keysSFTP Implementation in Windows SystemsMicrosoft operation systems do not provide any built-in means to organize a protected SFTP server. To do it, open-source or proprietary solutions, like Core FTP, FileZilla, CYGWIN, OpenSSH, FTP Shell, IPSwitch, etc., have been used.However, in October, 2015, Microsoft development PowerShell team the release of the OpenSSH candidate for Windows, being a port of OpenSSH for win32. Now Win32-OpenSSH project has a pre-release status. According to the developers’ plans, this year the final release will be ready.Let’s consider the configuration of the SFTP server running Windows Server 2012 R2 using Win32 OpenSSH package. Installation of Win32 OpenSSH on Windows Server 2012 R2You can download a compiled version of the package here:. We need a version for 64-bit Windows version: OpenSSH-Win64.zip (4 MB). Extract the archive to the target directory: C:OpenSSH-Win.

Start PowerShell command prompt with the administrator privileges and go to the OpenSSH directory: Cd C:OpenSSH-Win. Generate SSH keys for the server (they are necessary to start sshd):ssh-keygen.exe –Agenerating new host keys: RSA DSA ECDSA ED25519. Allow the incoming traffic on Port 22 (SSH server) in Windows Firewall: New-NetFirewallRule -Protocol TCP -LocalPort 22 -Direction Inbound -Action Allow -DisplayName SSH.

The previous command won’t work in a client OS. In this case another command is used:netsh advfirewall firewall add rule name='SSH Port' dir=in action=allow protocol=TCP localport=22. To enable authentication using keys:powershell.exe.install-sshlsa.ps1. Restart your server:Restart-Computer. Open the configuration file C:OpenSSH-Win sshdconfig in any text editor, find and change the value of Subsystem sftp to C:OpenSSH-Winsftp-server.exe.

Install sshd service.sshd.exe install. Specify that it has to be started automatically during the system boot and start it: Set-Service sshd -StartupType AutomaticStart-Service sshd. Help!I’m following these instructions but on step 5:To enable authentication using keys:powershell.exe.install-sshlsa.ps1I get the following error.install-sshlsa.ps1: File C:OpenSSH-WinOpenSSH-Win64install-sshlsa.ps1 cannot be loaded.

I was able to install sftp server using above procedure, however I am getting the below error while attempting to connect to the server from sftp756 02:52:27:692 Accepted password for Administrator from 24.62.197.248 port 52064 ssh2756 02:52:28:169 fatal: ERROR.

Unfortunately, the procedure fails from the start. When trying to run install-sshlsa.ps1 as administrator, I receive a string of errors stating.install-sshlsa.ps1: The term ‘.install-sshlsa.ps1’ is not recognized as the name of a cmdlet, function, scriptfile, or operable program.

Check the spelling of the name, or if a path was included, verify that the path is correctand try again.At line:1 char:1+.install-sshlsa.ps1Looking at the extraction directory, I see that the mentioned ps1 file is not resident in the extracted files. I downloaded the 32 & 64 bit versions, and install-sshlsa.ps1 are not contained in either zip.
