hi iv been readin up on Wake on Lan and have been trying to get it working, iv enabled it in the bios but i dont know where to configure it in opensuse ? can anyone help thanks
btw im running opensuse 11.1.:\
It’s not an OS thing. When the computer is on standby power, it’s the hardware NIC that recognises the magic packet and triggers full power from the supply. So there is nothing to configure in the OS. But you of course need a WOL client program on the machine that’s doing the waking to send the magic packet.
There is one caveat though. In some cases the OS might leave the NIC in a non-wakeable state when shutdown. But this is specific to NIC models and circumstances. You’d have to try it out to see if this unlikely situation applies to you.
That’s why I had to add following lines to my /etc/init.d/halt.local:
/sbin/ifup eth0
/usr/sbin/ethtool -s eth0 wol g
hmmm i added the code, still a problem with it. I might try and do a bios update, but im not sure what motherboard i have. Is there a command i can use to find out its name and model ??
WOL is very HW dependent. Check with lspci which type of HW card you have and search the net.
The trick worked for my NIC - I thought it might also solve your problem.
Another way (nicer, perhaps) is to edit /etc/sysconfig/network/ifcfg-eth0 and set:
ETHTOOL_OPTIONS='wol g'
The next time you boot, WOL will be activated in the network card. Or you can sudo /usr/sbin/ethtool -s eth0 wol g once if you don’t want to wait until the next boot.
