Unattended solution to install cygwin and enable ssh server on Windows?

Solution 1:

Automating the Cygwin installation is described here. Once you've installed Cygwin, you need to run ssh-host-config to set up the ssh server. I don't know how easy that is to automate, but maybe you could do something with expect, and chain the two scripts together.

Solution 2:

Write-Host "Downloading Cygwin ..." -ForegroundColor Cyan
$cygwinSetup = '{0}\cygwin-setup.exe' -f $env:SystemDrive
$startBitsTransfer = @{
    Source      = 'https://www.cygwin.com/setup-x86.exe'
    Destination = $cygwinSetup
    ErrorAction = 'Stop'
}
if ([Environment]::Is64BitOperatingSystem) {
    $startBitsTransfer.Source = 'https://www.cygwin.com/setup-x86_64.exe'
}
try {
    Start-BitsTransfer @startBitsTransfer
} catch {
    (New-Object Net.WebClient).DownloadFile($startBitsTransfer.Source, $startBitsTransfer.Destination)
}
