What does "ethtool eth0 | grep Wake" as root say on the box you want to remotely wake up?

Supports Wake-on: pumbg

Wake-on: g

OK, then you should be good to go. Just to be clear, I'm assuming you wish to wake up william-desktop (IP: 192.168.1.70; MAC:00:e0:4c:e9:96:a7) from william-GA-78LMT-USB3?

Your "arp -n" from the latter didn't show william-desktop. Are you sure they are on the same LAN? If you "ping -c 1 192.168.1.70" and then "arp -n" does it show up?

If so, try powering down william-desktop, and then run "ether-wake 00:e0:4c:e9:96:a7" as root from william-GA-78LMT-USB3. If everything's good, william-desktop should power up.

good news
 

It wasn't on the same LAN but is now. Great news :

So what next?

Already given.

Note that this is based on CentOS / RedHat / Fedora. The command "ether-wake" may be different under Ubuntu.

william@william-GA-78LMT-USB3:~$ sudo etherwake 00:e0:4c:e9:96:a7
SIOCGIFHWADDR on eth0 failed: No such device


I ran sudo poweroff on the machine I wanted to wake.

Is Wakeonlan intended to switch PC's on from a position like that?

Hmmm... Weird.

When I ran the command from one of my CentOS boxens I got this:[CODE][root@samba2 ~]# ether-wake -v -D 00:e0:4c:e9:96:a7

Perhaps try increasing the debugging / verbosity for the command, and report the results. Note that you are running a different derivative of Linux, so your etherwake may be completely different software than my ether-wake.

Having done a bit of Googling, is seems like Ubuntu also has a "powerwake" command. You might want to try installing and running that.

[QUOTE=wildrabbitt;435121]I ran sudo poweroff on the machine I wanted to wake. Is Wakeonlan intended to switch PC's on from a position like that?[/QUOTE]

Yes. I often use this to bring machines back online after power failures and/or user shutdowns.

Can you tell me what this means ? :


<code>
william@william-GA-78LMT-USB3:~$ sudo etherwake 00:e0:4c:e9:96:a7
SIOCGIFHWADDR on eth0 failed: No such device

This was ran from the waker while it the only machine plugged into the modem.

I'm asking because I'm wondering if we identified correctly the machine to wake.

[QUOTE=wildrabbitt;435162]I'm asking because I'm wondering if we identified correctly the machine to wake.[/QUOTE]

Please take this as supportive... You seem to go out of your way to not follow suggestions. To be spoon-fed what to do next.

What happens when you run etherwake with deeper verbosity and/or debugging?

Have you tried using alternative programs from the waking machine? Have you tried thinking for yourself?

I try to be tolerant, but this is getting a bit ridiculous.

[QUOTE=wildrabbitt;435162]This was ran from the waker while it the only machine plugged into the modem.[/QUOTE]

Why on gods green earth would you think this would work?

How is william-desktop supposed to receive the broadcast message if it isn't plugged into the switch (on the modem)? Magic???

I know this wouldn't work with regards to switching on the machine we were

trying to wake.

I was trying to understand what arp -n

actually does and I wanted to try it (on the waker) with no other machines except the waker plugged in to the modem.
