1. Set up a configuration file .
   1. eg.
2. Open regedit.
3. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU.
4. Change the value of the UseWUServer attribute to 0.
In a command window run the following
5. for your sftp connection.  Call it "config" and put it in a folder called .ssh under your user folder (eg. c:\Users\{your name}\.ssh).

   Sample file:

Install

1. To make sure that the OpenSSH features are available for install, run the following in powershell:

   Code Block
   language powershell
   Get-WindowsCapability -Online | ? Name -like 'OpenSSH*'

   This should return the following:

   Code Block
   language powershell
   Name : OpenSSH.Client~~~~0.0.1.0 State : NotPresent Name : OpenSSH.Server~~~~0.0.1.0 State : NotPresent

   Then, simply install the client and/or server features as follows:

   Code Block
   language powershell
   # Install the OpenSSH Client Add-WindowsCapability -Online -Name OpenSSH.Client~~~~0.0.1.0 # Install the OpenSSH Server Add-WindowsCapability -Online -Name OpenSSH.Server~~~~0.0.1.0

   Both should return the following output:

   Code Block
   language powershell
   Path : Online : True RestartNeeded : False

   You should now be able to type ssh, sftp, scp or any other openSSH commands into your command window

   Code Block
   language bash

...

net stop wuauserv && net start wuauserv

1. Host sftp2aws HostName somehost.server.transfer.ca-central-1.amazonaws.com IdentityFile C:\Users\{your name}\Documents\sftp2aws-key User sftpaws HostKeyAlgorithms ssh-rsa Compression yes

   
   

   • Host - alias name for your connection
   • HostName - the actual destination of the sftp server
   • IdentityFile - your private key
   • User - username

2. Create a script holding command(s) to actually send the file.
   Sample script:

   Code Block
   put c:\yourfiletosend.txt exit

   
   

3. Run the sftp command:

   Code Block
   C:\>sftp -b C:\sftpScript.txt sftp2aws

   Here, the -b indicates you're running the sftp command in batch mode (ie. passing in a script) and sftp2aws is the connection you configured in your config file above.

   
   NOTE:  If this is the first time you are connecting to the sftp destination you may run into a problem because you don't explicitly trust the server's identity.  You may get the following message:

   Code Block
   Host key verification failed. Connection closed

   The best way to add this trust is to run the ssh command on the command line and answer yes to the question Are you sure...:

   Code Block

   C:\>ssh sftp2aws The authenticity of host 'somehost.server.transfer.ca-central-1.amazonaws.com (xx.xx.xxx.xxx)' can't be established. RSA key fingerprint is SHA256:blahblahblah. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'somehost.server.transfer.ca-central-1.amazonaws.com,xx.xx.xxx.xxx' (RSA) to the list of known hosts. Connection to somehost.server.transfer.ca-central-1.amazonaws.com closed by remote host. Connection to somehost.server.transfer.ca-central-1.amazonaws.com closed.

   This will create the known_hosts file in your .ssh folder if it isn't already there, and it will add an entry for the destination.  An entry in that file indicates the destination is trusted.
