wake on lan and Ubuntu PPC

[meg23]

I am running a G4 450 MHz PPC with Feisty and OS X installed on two separate harddrives. OS X's wake on lan is

enabled and works when I send a packet with wakeonlan, however, when Ubuntu is shutdown on the machine (which

is the default hard disk), sending a wake on lan request does not start up the system. Because of this, it

leads me to believe that something is improperly configured on the Ubuntu hard disk to allow wake on lan. Has

anyone had similar problems? Is there anything in particular, besides BIOS, that needs to be configured to

allow wake on lan? Additionally, is there any accessible feature in OPENfirmware to allow wake on lan.

Here is the output from sudo ethtool eth0.

I noticed a little tool called "etherwake" has a ppc port for it, and see that 1.09 is available in Hardy PPC when I browsed with Synaptic.

The mention of bios in the description threw me off since we are openfirmware, but perhaps this might work for ppc?

UPDATE - upon further inspection, it appears that this utility only allows you to send the magic wakeup packet from the machine, not actually respond to it.

Aha, this looks good though I'm going to have to go through it a few times and see if it works on ppc.

If you do get wake on lan to work please post the output of sudo

ethtool eth0 for comparisons sake. I am interested to see what the

transceiver line reads. The transceiver should be listed as

internal but it is not. I am not sure if this would make a

difference.

Here's my ethtool eth0 on my G5 iMac using a Sun GEM card:

Settings for eth0:
Supported ports: [ TP MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
Advertised auto-negotiation: Yes
Speed: 100Mb/s
Duplex: Full
Port: MII
PHYAD: 0
Transceiver: external
Auto-negotiation: on
Supports Wake-on: g
Wake-on: d
Current message level: 0x00000007 (7)
Link detected: yes

I was able to set the Wake-on paramater from "d" to "g" by using

sudo ethtool -s eth0 wol g

But I noticed that after reboot, it reverted back to "d" again. Maybe there is something about the halt that needs to be addressed so it will keep this setting.

This is a bit new to me - I guess you need a "magic packet" specifically addressed to the machine to wake it up as well, rather than just detecting overall lan activity?

And I wonder if my card is even supported - I took a look at /usr/share/doc/ethtool/README.Debian and my Sun GEM is there, but I don't think I have the gigabit ethernet card...

My ethtool option for wol has a script installed to keep the

settings, however, the machine will not boot up at all.

Do you have OS X installed along with Ubuntu? If so, how are the

partitions set up? My Mac PPC will wake on lan with OS X.

I used to dual-boot it, but lately I just run Linux on the internal drive, and when I need OSX, I just boot from an external firewire drive I loaded osx onto - using the alt/option key to choose it at boot time.

When finished, back into the drawer.. :)
