 6 | # WakeOnLAN
 7 | A simple C program that sends a magic packet
 8 | 
 9 | You can use this program to wake up a PC over the network. It sends the so called magic packet to the network card of the target PC, instructing it to open the PC. [[Download]](https://github.com/GramThanos/WakeOnLAN/releases)
10 | 
11 | ___
12 | 
13 | ### Usage
14 | ```bash
15 | ./WakeOnLAN <mac address>[ <broadcast address>]
16 | ```
17 | The first parameter is the mac address of the target (usually your's network card's mac address).
18 | The second parameter is optional and defines the broadcast address to send the packet.
19 | 
20 | Example
21 | ```bash
22 | ./WakeOnLAN 00:11:22:33:44:55 192.168.1.255
23 | ```
