PowerShell Wake-on-lan script

*note* I forgot this post still was in my drafts folder, I posted the script in the PowerShell Newsgroup and asked if someone could test it and I got confirmed that it did work,thanks again,  so here it is :

I came along this post about WOL (wake-on-Lan) in PowerShell : Wake-On-LAN script , and that it did use an external .EXE

As I made scripts (o.a. VB.NET) for this before , I almost instanty did think

TMTOWTDI

I did know that it was something with a Magic Packet and a WakeUp bytes containing the MAC adress,

As I already did read this post, C# to PowerShell Translation Thought Process , and to make it easier I added C# to my search.

(before I did .NET or VB.NET ) , but the C# is easy to search on and examples are more easy to translate.

so I did my first (and last) Google search only with : WOL C#

The first page shown was :

CodeKeep Snippet: Wake On LAN (WOL) (C#)

I opened was this one and hit-in-one a perfect sample, so I just worked my way down an had my script ready in minutes

$mac = [byte[]](0x00, 0x0F, 0x1F, 0x20, 0x2D, 0x35)

$UDPclient = new-Object System.Net.Sockets.UdpClient
$UDPclient.Connect(([System.Net.IPAddress]::Broadcast),4000)
$packet = [byte[]](,0xFF * 102)
6..101 |% { $packet[$_] = $mac[($_%6)]}
$UDPclient.Send($packet, $packet.Length)

(but then... oops no machine to test around... Off to friend for coffee ;-) ) :

we have not been able to test it but meanwhile made some parser lines for other formats of mac adresses :
