wrong network interface / wol

[ber56]

Hello,

I have a proxmox cluster (7.3), with private cluster network.
cluster network : 192.168.19.x

Only 1 node (frontal) has 2 interfaces:
vmbr0: on my network, accessible via web gui https://172.25.34.10:8806
vmbr1: on private cluster network (192.168.19.1)


if I do :

pvenode wakeonlan cluster02

does not work, because the command is sent to the wrong interface (vmbr0)
Same thing with graphical interface.

wakeonlan xx:xx:xx:xx:xx:xx either

etherwake -b -i eth1 xx:xx:xx:xx:xx:xx is ok.


Is it possible to specify on which interface we want to send the magic packet with proxmox ?

Sincerely

Hi,
no unfortunately this is not implemented, the interface on which the magic packet is send out is determined by the routing table.

Could you open feature request for this at https://bugzilla.proxmox.com/, it should be possible to include the interface to send the packet to in the config, and set it via setsockopt by specifying SO_BINDTODEVICE.

ok, I do this ...

I have the same issue (in 8.1.3) and looked for that feature/enhancement request in bugzilla but found nothing so I'll probably open it myself.
Looking at the code it should be easy to replace the hardcoded local broadcast (255.255.255.255) with a new configuration option (e.g. "Broadcast address for Wake on LAN") that defaults to 255.255.255.255. That way it would be possible to direct the broadcast (e.g. 192.0.2.255) to a specific subnet interface if needed.

Hi,
yes do please open an issue in our bugtracker for this, I will have a look at this when time allows. Thanks!
