Wake On Lan(WOL) tool/class for Ruby

Download: wakeonlan.rb.

Wake On Lan(WOL) means to wake up or power on remote PCs with LAN access using Magic Packet technology. The Maic Packet is a broadcast packet containing MAC address of PCs. See Magic Packet for more details. We need a list of MAC address(or Ether address) to make Magic Packets. See "making a list of ether address". See also "Wake On Lan(WOL) with ping comand".

Usage(as a command)

$ ruby wakeonlan.rb [broadcast_address] < data_text

Each line of data text is of the form "ip_address host_name MAC_address".
For example:

10.20.30.40 host1  101:102:103:104:105:106
10.20.30.50 host2  201:102:103:104:105:106
10.20.30.60 host3  301:102:103:104:105:106

Usage(as a class)

require "wakeonlan"
wol=WakeOnLan.new
wol.wake("101:102:103:104:105:106", "10.255.255.255", "10.20.30.40")
# args: MAC_address Broadcast IP_address
