I'm asking this question on behalf of a friend. I don't have access to this hardware, but I can contact my friend to get more info as required.
Does anyone know how to get wake-on-lan to work on a Dell 4550 with any recent version of Ubuntu? My friend saw on the Ubuntu discussion forums that someone had wake-on-lan working with Ubuntu 8.04, but he hasn't seen anything newer than that.
Here is his statement:
I inherited a 4550 (my gamer son got a newer machine) and I can't get WOL to work with Ubuntu 9.04 or 9.10. I can set and see the 'g' in ethtool, and the LEDs adjacent to the built-in Ethernet connector stay on when the machine is is in suspend mode. Pressing the power button in suspend mode wakes up the machine (about five seconds to the Ubuntu splash screen; no booting).
(BTW, those Ethernet LEDs didn't stay on when running 9.04.)
I'm sending magic packets from my Linux-based router machine (not Ubuntu). If I'm logged into the 4550, I can run tcpdump port 40000 (default port for magic packets on the router box), and I can see the magic packets; I can dump them with tcpdump -xx -XX too. But with all of the above working, the 4550 won't wake on lan.
What am I missing?
Thanks in advance.
P.S. Merry Christmas and happy holidays everyone!
