Wake on lan works

I previously tried to get wake-on-lan to work and had no luck. I was never sure if my code was wrong, or if a firewall was filtering the command of if my motherboard just doesn't support it (probably the latter).
Today I got a new computer and the old wake-on-lan.py worked!

So here's the program that works for me.

#!/usr/bin/env python

import socket
import struct
import sys

def wake_on_lan(macaddress):
""" Switches on remote computers using WOL. """

# Check macaddress format and try to compensate.
if len(macaddress) == 12:
elif len(macaddress) == 12 + 5:
sep = macaddress[2]
macaddress = macaddress.replace(sep, '')
raise ValueError('Incorrect MAC address format')

# Pad the synchronization stream.
data = ''.join(['FFFFFFFFFFFF', macaddress * 20])
send_data = ''

# Split up the hex values and pack.
for i in range(0, len(data), 2):
send_data = ''.join([send_data,
struct.pack('B', int(data[i: i + 2], 16))])

# Broadcast it to the LAN.
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
sock.sendto(send_data, ('', 7))

if __name__ == '__main__':
machines = {
'hera' : '01-23-45-67-89-AB',
'zeus' : 'CD:EF:01:12:45:67',
machine = 'scott'
if len(sys.argv) > 1:
machine = sys.argv[1].strip()

In the BIOS settings I turned on both "PME Event Wakeup" and "Power On Ring" (neither of which is written "wake on LAN").

I'm quite happy with the computer, it has a very silent power supply and I also got a 22" Samsung LCD to go with it.
No I'll have to go and setup my old computer for Victor.
