Wake on lan doesn't work

[Valerio Pachera]

Hi, I have a proxmox 4.4 installation on a laptop.
This laptop has wake on lan enabled on bios side.
I checked also from shell

ethtool eth0 | grep -i wake
Supports Wake-on: pumbg
Wake-on: g

I turned off the laptop and tried to wake it from another linux server by

wakeonlan <macaddress>
etherwake <macaddress> -D

and also by an app from a windows 10 pc.

It doesn't turn on!

I looked the /etc/network/interfaces file and there are no option related to wake on lan.
So I wonder if the wake-on get disabled during boot by some instruction I don't know about.

thank you.

Proxmox VE does not have any specific handling for wake on lan, i.e. works as it does in any Debian.

Important: file /etc/default/halt must contain the line

NETDOWN=no

If this has been done correctly and ethtool show WOL active (as above), try:

- if your wakeonlan application wakes a different machine correctly

- if yes: does it work with your laptop if you use a different OS.

It seems a switch issue because wake on land doesn't work with other pc as well.

Check with

tcpdump -e -n -i eth..

if the magic packet arrives - if not it is a switch issue indeed.
