测试是否启用了 powershell 远程处理

Question

我一直在寻找，但找不到我要找的具体内容，我需要一种可以测试大约 900 台机器并判断是否启用了 powershell 远程处理的方法，我发现使用下面的脚本我可以验证powershell 已安装，但它没有检查它是否可以实际远程管理机器，有什么想法吗？

function Check-PSVersion
{

[CmdletBinding()]
Param (
    [Parameter(Mandatory = $true)]
    $ComputerName
)
if (Test-Path $ComputerName)
{
    $Computers = Get-Content $ComputerName
}
Else
{
    $Computers = $ComputerName
}

Foreach ($Computer in $Computers)
{
    Try
    {
        Write-Host "Checking Computer $Computer"
        $path = "\\$Computer\C$\windows\System32\WindowsPowerShell\v1.0\powershell.exe"
        if (test-path $path) { (ls $path).VersionInfo }
        else
        {
            Write-Host "Powershell isn't installed" -ForegroundColor 'Red'
        }
        Write-Host "Finished Checking Computer $Computer"
    }

    catch { }
}
}

Answer 1

您可以使用 Test-WSMan cmdlet 检查 WinRM 服务是否正在远程计算机上运行。

[bool](Test-WSMan -ComputerName 'ComputerName' -ErrorAction SilentlyContinue)

冒着偏离主题的风险......

function server_available?( $_server_to_act_on ) {
   if ( Test-Connection -ComputerName $_server_to_act_on -Count 1 -Quiet ) {
     Write-Host "`nTest-Connection: $_server_to_act_on OK" -NoNewline
     if ( [bool](Test-WSMan -ComputerName $_server_to_act_on -ErrorAction SilentlyContinue) ) {
       Write-Host ", Test-WSMan: $_server_to_act_on OK" -NoNewline
       if ( [bool](Invoke-Command -ComputerName $_server_to_act_on -ScriptBlock {"hello from $env:COMPUTERNAME"} -ErrorAction SilentlyContinue) ) {
         Write-Host ", Invoke-Command: $_server_to_act_on OK" -NoNewline
         return $true
       }
     }
  }
  return $false
}

根据上面的 Straffs 代码，这是我的工作版本，说明如何确定 PS Remoting 是否在 1 台或多台计算机上运行。保存代码并将其与名为“PCList.txt”的文件放在同一文件夹中运行脚本，它将显示列表中每个系统的状态，并在每次以 .CSV 格式运行时生成一个新报告，可直接单击进入Excel。在 PCList.txt 文件中每行放置一台机器。您必须具有远程计算机的本地管理员访问权限才能正常工作，始终“以管理员身份运行”

function Test-CanRemoteSystetmRunPSCmd( $_server_to_act_on ) 
{

  Write-host "`n`n$Counter of $Total - Testing System:`t$_server_to_act_on`n"
  if ( Test-Connection -ComputerName $_server_to_act_on -Count 1 -Quiet ) 
  {
    Write-Host "`nTest-Connection: $_server_to_act_on OK, " -NoNewline
    if ( [bool](Test-WSMan -ComputerName $_server_to_act_on -ErrorAction SilentlyContinue) ) 
    {
      Write-Host "Test-WSMan: $_server_to_act_on OK, " -NoNewline
      if ( [bool](Invoke-Command -ComputerName $_server_to_act_on -ScriptBlock {"hello from $env:COMPUTERNAME"} -ErrorAction SilentlyContinue) ) 
      {
        Write-Host "Invoke-Command: $_server_to_act_on OK. `n"  
        return "$_server_to_act_on,SUCCESS"
      }
      Else
      {

        Return "$_server_to_act_on,FAILED Invoke-Command"
        Continue 

      }
    }
    Else
    {

      Return "$_server_to_act_on,FAILED Test-WSMAN"
      Continue 

    }
  }
  Else
  {

    Return "$_server_to_act_on,FAILED Test-Connection"
    Continue 

  }  
}

Clear-Host
# Intialze the report name  and header anchored in the current script folder 
$_NewRunTime    = Get-Date                                                              # Initialize the time of the script being run

$_ReportHeader = "Computer Name,PS Remoting Status,Test Time"
 Out-File -FilePath $_report_File -InputObject $_ReportHeader -Encoding UTF8  # Add a line to the report

$PCList = Get-Content -Path "$PSScriptRoot\PCList.txt"
$Total = $PCList.Count
$Counter = 0

ForEach ($PC in $PCList)
{
  $Counter = $Counter + 1
 $T = Measure-Command {$RemoteCommandCheck = Test-CanRemoteSystetmRunPSCmd $PC}

 $TestTimeTotal = $T.Totalseconds
  If($RemoteCommandCheck -like "*Fail*")
  {

    Write-Host "$RemoteCommandCheck,$TestTimeTotal" -ForegroundColor Red -BackgroundColor Yellow

  }
  Else
  {

    Write-Host "$RemoteCommandCheck,$TestTimeTotal" -ForegroundColor White -BackgroundColor DarkGreen

  }
  $RemoteCommandCheck + ',' + $TestTimeTotal | Out-File -FilePath $_report_File -Encoding UTF8 -Append
}

这是一个循环脚本，用于检查远程 powershell 是否正常工作，基本上主机是否正常工作。我已经让它冻结了，尽管它仍然可以 ping 通并且端口仍然处于活动状态。

# start-threadjob avdcheck.ps1 -StreamingHost $Host
# $s2 is an array of new-pssession's

while ($true) {
  foreach ($s in $using:s2) {
    icm $s { pwd } > $null
    if (! $?) {
      [console]::beep(500,300)
      write-host ($s.computername + " is not responding " + (get-date))
    }
  }
  sleep (60*15)
}
