After I shut down the PC, I used different tools to send out the magic package, but nothing happens. Any suggestion?
Your card is supported, now to configure wake-on-lan:
-
Install
ethtool
sudo apt-get install ethtool
-
Edit
/etc/rc.local
to add this line before theexit 0
line:ethtool -s eth0 wol g
-
Find out the MAC address of your network card (replace
eth
if with your interface name,eth0
,eth1
, ..):ifconfig eth | grep "HWaddr" | awk '{print $5}'
-
Shutdown the machine. You should be able to wake it up using:
wakeonlan your_mac
You need to install ethtool by typing with root privilage:
apt-get install ethtool
Next step is to enable wake on lan in your system by typing:
ethtool -s eth0 wol g
I describe such scenario and few optional next step on my blog
