WOL webpage setup.

This is probably insecure and only really useful on home local network; I
suggest putting this behind a reverse SSH proxy.

* sudo aptitude install etherwake acpitool ethtool pciutils
* copy apache-cgi-section to /etc/apache2/sites-available/default-ssl
  (or related). Should be placed in <VirtualHost _default_:443>
* generate a login/password to protect the page

  sudo htpasswd -cs /etc/apache2/wol-htaccess <user>
  sudo chgrp www-data /etc/apache2/wol-htaccess

* copy wake.py to cgi-bin directory and set permissions

  sudo chown root:www-data /usr/lib/cgi-bin/wake.py
  sudo chmod 0550 /usr/lib/cgi-bin/wake.py

* allow all users to execute etherwake (as root), so webpage will work

  sudo chmod u+s /usr/sbin/etherwake

* enable WOL on all interfaces you care about

  sudo ethtool -s eth0 wol g
  sudo ethtool eth0

* verify S5 state is set for ethernet cards

  sudo lspci -k
  acpitool -w

* if state is *not* set, copy wake-on-lan-config to /etc/init.d, and make sure
  to update pciNIC with your specific address; add to load before bringing up
  network interfaces
* copy wake-on-lan to /etc/network/
* add custom handlers in /etc/network/interfaces to enable WOL on startup

  iface eth0 inet dhcp
    ...
    post-up /etc/network/wake-on-lan
    post-down /etc/network/wake-on-lan
