There’s a lot of different tools out there to essentially SSH to a Linux host. They seem to come short when one needs to use secure copy. WinSCP has been around forever and is a relatively mature tool for doing SCP on a Windows client. My requirement is to copy files from a Linux server to a Windows client. WinSCP seems to be the best fit for my one need. Here are the general steps to getting it done:
- First install WinSCP wrapper to enable use of SCP from PowerShell. Windows Management Framework 5.0 is a prerequisite.
- Run the WinSCP application to collect the key from the target Linux host.
- Generate credentials to be used by a script to copy files. Run a script to copy the files.
- If needed, set up a scheduled task to run the copy script on an interval.
Download WinSCP .NET assembly for use with PowerShell: https://winscp.net/eng/docs/library_powershell#powershell_scripting
In PowerShell running as administrator, run the following:
Install-Module -Name WinSCP
Check the install by running the following:
Get-Command -Module WinSCP
Store credentials to be used in a later script.
Save Password to File
$credential = Get-Credential
$credential.Password | ConvertFrom-SecureString | Set-Content G:\scripts\PasswordFile.txt
Run a script the uses the password file to access the Linux server and copy over your files.
$session = New-WinSCPSession -Hostname <Linux Host> -Credential $credential -SshHostKeyFingerprint "ssh-rsa-xx-xx-xx-xx-xx-xx-xx-xx-xx-xx-xx-xx-xx-xx-xx-xx"
Receive-WinSCPItem -WinSCPSession $session -Path “/…/somefile” -Destination “C:\folder\destination\etc\”
Remove-WinSCPSession -WinSCPSession $session
