How to use Wake On Lan (WOL):

For windows:

Save the script below to a file named Wol.ps1. Change the mac address of your machine accordingly.

# Function to send Wake-on-LAN (WoL) Magic Packet
function Send-WoL {
    param (
        [Parameter(Mandatory = $true)]
        [string]$MacAddressDelimetered,
        
        # CHANGE THE BROADCAST ADDRESS ACCORDING TO YOUR LAN SUBNET.
        # THIS IS FOR COMPUTERS THAT HAS AN IP OF: 192.168.1.xxx
        [string]$BroadcastAddress = "192.168.1.255",
        [int]$Port = 9
    )
    
    # Remove any delimiters in the MAC address
    $MacAddress = $MacAddressDelimetered -replace "[:-]", ""
    
    # Validate MAC address length
    if ($MacAddress.Length -ne 12) {
        Write-Error "Invalid MAC Address. Ensure it is a 12-character hexadecimal string."
        return
    }

    # Convert the MAC address string into a byte array
    $MacBytes = @()
    for ($i = 0; $i -lt 12; $i += 2) {
        $MacBytes += [convert]::ToByte($MacAddress.Substring($i, 2), 16)
    }

    # Create the magic packet: 6 bytes of 0xFF followed by 16 repetitions of the MAC address
    $MagicPacket = [byte[]](0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF) + ($MacBytes * 16)
    

    # Send the magic packet over UDP
    $UdpClient = New-Object System.Net.Sockets.UdpClient
    $UdpClient.Connect($BroadcastAddress, $Port)
    $UdpClient.Send($MagicPacket, $MagicPacket.Length)
    $UdpClient.Close()

    Write-Host "Wake-on-LAN packet sent to $MacAddressDelimetered via ${BroadcastAddress}:${Port}"
    
}

# Replace with the MAC address of the device you want to wake up
Send-WoL -MacAddress "AA:BB:CC:DD:EE:FF"

For Linux (debian based):

Install wakeonlan:

sudo apt-get install wakeonlan

Use this command to broadcast a wol event, change the mac address of the machine you've set up wol

wakeonlan xx:yy:zz:11:22:33

Send WOL to a targeted ip:

wakeonlan -i 192.168.1.123 AA:BB:CC:DD:EE:FF

Using a desktop launcher for convenience:

Save these to a file named: WakeOnLan.desktop and put it to your desktop
