Did you know that you can turn on a computer over LAN or Internet? Yes you can! Why will you need it? For example you have a computer that you need to connect to remotely. So instead of keeping it always on, you can turn it on remotely and then just turn it of when you done.
I need it for my file server that I’ve made. I’ve installed Ubuntu a cheap PC and configured it as network file server. I want to hide it somewhere far at home and it will be connected only with power and LAN cable. I don’t need it always on so here how you set the “Wake on LAN”.
