powershell遠程喚醒系統

從MS官方blog上看到一則很實用的指令碼，用來遠程喚醒系統

1、確認你的系統是否支援遠程喚醒

#ethtool etho|grep ‘Wake-on’

Supports Wake-on: pumbag

Wake-on: g

g 表示已啟動

2、編寫指令碼

########################

param($MacAddress)
echo “Wake up $MacAddress Now!”
[byte[]] $MagicPacket = 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF
$MagicPacket += ($MacAddress.split(‘-’) | foreach {[byte] (’0x’ + $_)}) * 16
$UdpClient = New-Object System.Net.Sockets.UdpClient
$UdpClient.Connect(([System.Net.IPAddress]::Broadcast) ,9)
$UdpClient.Send($MagicPacket,$MagicPacket.length)

########################

儲存為wakeup.ps1

3、測試

PS D:programmepowershell> ping 192.168.1.188 -n 1;.wakeup.ps1 00-16-11-11-11
-11;ping 192.168.1.188 -n 3
