Powershell Remote Wake-up system

The official MS blog shows a very practical script to remotely wake up the system.

1. Check whether your system supports remote wakeup.

# Ethtool etho | grep 'ake-on'

Supports Wake-on: pumbag

Wake-on: g

G indicates that the instance has been started.

2. write scripts

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

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)

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

Save as wakeup. ps1

3. Test

Ps d: programmepowershell> ping 192.168.1.188-n 1;. wakeup. ps1 00-16-11-11-11
