  1. Set up a configuration file 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:

    Code Block
    languagebash
    Host sftp2aws
    HostName      somehost.server.transfer.ca-central-1.amazonaws.com
    IdentityFile  C:\Users\{your name}\Documents\sftpsmmstranscandsdsftp2aws-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 - usernameRest is likely optional

  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:

      You may have to add the server's identity to known_hosts (John Sewchand (Unlicensed))

      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 following 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.
