"WakeMeOnLan is a new utility that allows you to easily turn on one or more computers on your network, by sending Wake-on-LAN (WOL) packet to these computers.
When your computers are turned on, WakeMeOnLan allows you to scan your network, and collect the MAC addresses of all your computers, and save the computers list into a file. Later, when your computers are turned off or in standby mode, you can use the stored computers list to easily choose the computer you want to turn on, and then turn on all these computers with a single click.
WakeMeOnLan also allows you to turn on a computer from command-line, by specifying the computer name, IP address, or the MAC address of the remote network card.
No need to hunt down your spouse's, kids, utility, etc., etc. notebook/PC anymore when all you need to do is wake it up... I don't know about you, but I hate having to get up and go into another room just to wake a notebook so I can put something on it (or take something off). Sure we could just leave them on 24x7, but that's lame. This way you get the best of both worlds?
