如何使用 PowerShell 發送 LAN 喚醒魔術包？

Question

我想使用 PowerShell 發送一個 WOL 魔術包，而不依賴任何第三方工具。

Answer 1

這是我用來發送WakeOnLan數據包的工作 PowerShell 單線：

$mac = '01:23:45:67:89:AB'; [System.Net.NetworkInformation.NetworkInterface]::GetAllNetworkInterfaces() | Where-Object { $_.NetworkInterfaceType -ne [System.Net.NetworkInformation.NetworkInterfaceType]::Loopback -and $_.OperationalStatus -eq [System.Net.NetworkInformation.OperationalStatus]::Up } | ForEach-Object { $targetPhysicalAddressBytes = [System.Net.NetworkInformation.PhysicalAddress]::Parse($mac).GetAddressBytes(); $packet = [byte[]](,0xFF * 102); 6..101 | Foreach-Object { $packet[$_] = $targetPhysicalAddressBytes[($_ % 6)] }; $client = [System.Net.Sockets.UdpClient]::new([System.Net.IPEndPoint]::new(($_.GetIPProperties().UnicastAddresses | Where-Object { $_.Address.AddressFamily -eq [System.Net.Sockets.AddressFamily]::InterNetwork })[0].Address, 0)); try { $client.Send($packet, $packet.Length,[System.Net.IPEndPoint]::new([System.Net.IPAddress]::Broadcast, 9)) | Out-Null } finally { $client.Dispose() } }

這是一個更易讀的版本：

$mac = '01:23:45:67:89:AB'; [System.Net.NetworkInformation.NetworkInterface]::GetAllNetworkInterfaces() | Where-Object { $_.NetworkInterfaceType -ne [System.Net.NetworkInformation.NetworkInterfaceType]::Loopback -and $_.OperationalStatus -eq [System.Net.NetworkInformation.OperationalStatus]::Up } | ForEach-Object {
    $networkInterface = $_
    $localIpAddress = ($networkInterface.GetIPProperties().UnicastAddresses | Where-Object { $_.Address.AddressFamily -eq [System.Net.Sockets.AddressFamily]::InterNetwork })[0].Address
    $targetPhysicalAddress = [System.Net.NetworkInformation.PhysicalAddress]::Parse($mac)
    $targetPhysicalAddressBytes = $targetPhysicalAddress.GetAddressBytes()
    $packet = [byte[]](,0xFF * 102)
    6..101 | Foreach-Object { $packet[$_] = $targetPhysicalAddressBytes[($_ % 6)] }
    $localEndpoint = [System.Net.IPEndPoint]::new($localIpAddress, 0)
    $targetEndpoint = [System.Net.IPEndPoint]::new([System.Net.IPAddress]::Broadcast, 9)
    $client = [System.Net.Sockets.UdpClient]::new($localEndpoint)
    try { $client.Send($packet, $packet.Length, $targetEndpoint) | Out-Null } finally { $client.Dispose() }
}

大致基於Wake on LAN using C#中的代碼。
