rhel 4 linux WOL wake on lan
Hi guys,
Two boxes on the same .23 subnet 192.168.1.x
The box I wanted to shutdown and restart remotely
went down, but didn't come back up when I used ether-wake 00:11:22:etc:etc:
The sleeper has two nics, but only one with cable. I configured both nics to wake on lan using the g option.
The sleeper is an IBM 336
I thought I'd setup the remoteMachine, by using ethertool to set Wake-on to g, which is supposed to mean it'll repond to the MagicPacket.
The thing is, I wasn't able to get a monitor onto the sleeper, or a keyboard,
so I had to pull the power cable to get it backup. Not great you'll agree.
So, with the above information in mind, where would you start in order to figure out why my ether-wake isn't waking the sleeper?
I even modifed the sleepers /etc/init.d directory so that it contains an executable file called wol.sh, but as the sleeper didn't reboot, I'm not sure that even worked. Do I have to do something with chkconfig so that my ethtool tweak is persistent?
Many questions, any help, as always, is very much appreciated.
The reason I'm doing this:
We have an electricity bill we'd like to reduce.
Is using wake on lan a good idea, or something to be avoided.
I'm looking for the voice of experience, to help me stand on the shoulders of giants.
