Vmware SSH PowerShell 技巧与plink.exe

最近我需要执行一些PowerCLI的行动，从ESXi Shell中，你可知道，目前还没有从的cmdlet允许您运行shell命令，但这是流行在社区内的一个选项是使用第三方工具，称为砰砰。exe来运行通过SSH命令。

 

下载plink.exe通过PowerShell。

我在写脚本的人谁，我不知道已经有安装砰砰，我想他们很少有使用该脚本时没有力气，所以我想分享的第一招是能够检查plink.exe下载它，如果它不是在同一个目录中的脚本，这可以看出如下：

$myDir = Split-Path -Parent $MyInvocation.MyCommand.Path
$PlinkLocation = $myDir + "\Plink.exe"
If (-not (Test-Path $PlinkLocation)){
	Write-Host "Plink.exe not found, trying to download..."
	$WC = new-object net.webclient
	$WC.DownloadFile("~sgtatham/putty/latest/x86/plink.exe",$PlinkLocation)
	If (-not (Test-Path $PlinkLocation)){
		Write-Host "Unable to download plink.exe, please download from the following URL and add it to the same folder as this script: ~sgtatham/putty/latest/x86/plink.exe"
		Exit
	} Else {
		$PlinkEXE = Get-ChildItem $PlinkLocation
		If ($PlinkEXE.Length -gt 0) {
			Write-Host "Plink.exe downloaded, continuing script"
		} Else {
			Write-Host "Unable to download plink.exe, please download from the following URL and add it to the same folder as this script: ~sgtatham/putty/latest/x86/plink.exe"
			Exit
		}
	}	
}

Accept plink.exe host key automatically

Secondly when connecting to a host for the first time you will need to accept the host key and allow plink.exe to connect to the host, the message is similar to the one below:

At the moment there is no option in plink.exe to skip the host key checking, however after some searching and messing around I came upon a solution.

It turns out you can actually send a Y to the script you are running by simply piping “echo Y” to plink.exe, this sends a Y accepting the host key when the question is asked from the command line, this can be scripted like the below example:

Echo Y | Plink.exe…..

Hopefully someone will find these useful in the future as I did with this script.
