A simple C program that sends a magic packet

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]

./WakeOnLAN <mac address>[ <broadcast address>][ <interface>]

The first parameter is the mac address of the target (usually your network card's mac address). The second parameter is optional and defines the broadcast address to send the packet. The third parameter is optional and defines the source interface to send the packet from (not for Windows).

Example

./WakeOnLAN 00:11:22:33:44:55 192.168.1.255 eth0

or, from a file with MAC addresses inside:

./WakeOnLAN -f macs-list.txt

where macs-list.txt has one MAC address per line:

00:1A:2B:3C:4D:5E
00:11:22:33:44:55
12:34:56:78:90:AB
.
.
.

For Linux, you can compile the source using GCC

gcc WakeOnLAN.c -o WakeOnLAN

For Windows, you can compile the source using MinGW

gcc WakeOnLAN.c -o WakeOnLAN.exe -lwsock32

Or Open up a Visual Studio Native Tools Command Prompt, navigate to your source directory

cl WakeOnLAN.c -o WakeOnLAN.exe

GNU make can be used in order to compile the sources on Linux/Mac:

make

To clean everything:

make clean

CMake can also be used on Linux/Mac:

mkdir build
cd build
cmake ..
cmake --build .
