Hi - Thanks for your help. I think the ethtool trick is not helping. As per instructions, I have a file /etc/init.d/wakeonlanconfig which has
#!/bin/bash
ethtool -s eth0 wol g
exit
and when I do "ethtool eth0", I get (amongst other things)
Supports Wake-on: pg
Wake-on: g
Yet, when I powerdown the led for the nic goes off and wol does not work. I use "wakeonlan -i 192.168.0.2 -p 8 00:16:E6

D:B9

D" from another computer on my lan (the IP and MAC are correct according to ifconfig on 192.168.0.2, i.e.
$ ifconfig
eth0 Link encap:Ethernet HWaddr 00:16:e6:dd:b9:dd
inet addr:192.168.0.2 Bcast:192.168.0.255 Mask:255.255.255.0
)
So maybe this is something specific to my hardware. I listed the output of lspci below. I have two other types of machines that I can experiment with to see if I can get wol working. That might be a useful exercise to narrow down the possibilities.
thanks for your help,
Mark
