wol_server

Wake-on-LAN (WoL) server for broadcasting magic packets on a local network. For my setup, my machines use static IP addresses, but I cannot configure the Telenet router to remember these IP addresses. So I have this program always running on my CPU server. When it receives a HTTP request to wake up a device, it the magic packet will be broadcasted on the local network.
