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 :
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 :
PoSH> $mac = [byte[]]("00-0F-1F-20-2D-35".split('-') |% {[int]"0x$_"})
PoSH> $mac
0
15
31
32
45
53
PoSH> "000F1F202D35" -match "(..)(..)(..)(..)(..)(..)" | out-null
PoSH> $mac = [byte[]]($matches[1..6] |% {[int]"0x$_"})
PoSH> $mac

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