Получить список MAC-адресов из pingable IP-адресов

Question

ЦЕЛЬ: получить массив, содержащий имя хоста (через DNS, пустое, если не найденное), MAC-адрес и IP-адрес активных устройств в сети. Это должно работать для не-windows-устройств (коммутаторы, хосты ESX и т. Д.), Поэтому WMI отключен.

То, что я до сих пор, на основе этого post:

[CmdletBinding()] 
Param (
    [string]$Network = "192.168.1", 
    [int]$IPStart = 1, 
    [int]$IPEnd = 255 
) 

$outArray = @() 
ForEach ($IP in ($IPStart..$IPEnd)) 
{ 
    Try { 
     $Ping = Get-WMIObject Win32_PingStatus -Filter "Address = '$Network.$IP' AND ResolveAddressNames = TRUE" -ErrorAction Stop 
    } 
    Catch { 
     $windows = 0 
     $hostname = ([system.net.dns]::GetHostByAddress($IP)).hostname 
     Continue 
    } 
    if ($Ping.StatusCode -eq 0) 
    { 
     Try { 
      $Adapters = Get-WmiObject Win32_NetworkAdapter -Filter "NetEnabled = True" -ComputerName $Ping.ProtocolAddressResolved -ErrorAction Stop 
     } 
     Catch { 
      $windows = 0 
      Continue 
     } 
     if ($windows -ne 0) { 
      ForEach ($Adapter in $Adapters) 
      { $Config = Get-WmiObject Win32_NetworkAdapterConfiguration -Filter "Index = $($Adapter.Index)" -ComputerName $Ping.ProtocolAddressResolved 
       ForEach ($IPAddr in $Config.IPAddress) 
       { $adapterInfo = New-Object PSObject -Property @{ 
         Host = $Ping.ProtocolAddressResolved 
         'Interface Name' = $Adapter.Name 
         'IP Address' = $IPAddr 
         'MAC Address' = $Config.MACAddress 
        } 
        $outArray += $adapterInfo 
       } 
      } 
     } 
    } 
    Else { 
     $MACAddress = ?  # NEED THIS INFORMATION 

     $hostinfo = New-Object PSObject -Property @{ 
       Host = "" 
       'Interface Name' = "" # Don't care in this instance. Placeholder to keep the array happy 
       'IP Address' = $IP 
       'MAC Address' = $MACAddress 
      } 
     $outArray += $hostInfo 
    } 
}

Answer 1

Существует несколько способов удаленного доступа к MAC-адресу с компьютера под управлением Windows.

getmac /S <computername> /FO CSV | ConvertFrom-Csv

Или

Get-WmiObject win32_networkadapterconfiguration | select description, macaddress

Я обнаружил, что getmac, как правило, данные, которые вы хотите, запрос WMI будет нужно немного фильтрации. Но вы можете сравнивать и фильтровать результаты запроса WMI на основе сетевых интерфейсов, которые вы обнаруживаете в своем скрипте.

Также измените свой [int]$IPEnd = 255 на [int]$IPEnd = 254 255 - это широковещательный адрес вашей сети.

Редактировать: Хорошо, потому что у вас, кажется, сложный набор ограничений, но у вас есть единый домен столкновения (рад его слышать!).

Похоже, что вам нужно позвонить напрямую iphlpapi.dll.

Кто-то уже решил эту загадку, хотя взгляните на этот скрипт: http://poshcode.org/2763
