Wake on LAN from the command-line with mc-wol

Waking a machine up through a LAN connection can be very useful to turn on a computer if the power button is a pain to get to; say if you have a computer under your desk. It is also handy if you want to turn on a group of computers.

There are a number of Magic Packet senders that will wake a computer up over a LAN connection, but these are usually stand alone programs that need to be opened up and have data entered into them before they work. I wanted a more customizable solution.

Mc-wol is a command line utility that enables you to wake up a machine on your local area network. Being a command line utility, it is easy to utilize in a shortcut on your desktop, place into a batch file, or use it in a scheduled task.

Don’t let the command line scare you. The syntax is really simple. To launch a computer, type mc-wol followed by the mac/ethernet address. i.e.:

mc-wol 91:34:eb:de:45:32


Wake on LAN software only works on computers which are in standby or hibernate modes.

Mc-wol is free and available from Matcode.com. You will also find a bunch of useful information on the page about simple settings you will need to check before WOL will work.

    This is a great tool, I used it when troubleshooting why I couldn’t get WoL to work through Microsoft’s System Center Configuration Manager 2007.

    It does not work with Eset Firewall. Any solutions?

    Your firewall should have little impact on WOL. It is probably another issue. The WOL happens before the WOL is loaded. I think it may be settings in your bios preventing WOL.
