Hi,

I'm playing with docker on a fresh OMV 4 installation and I need to set my network card's promiscuous mode for the macvlan system.

I can check the mode with

ip -d link show interface_name

I can enable promiscuous mode with

ip link set interface_name promisc on

However, when I reboot, promiscuous mode is no longer enabled. How can I persist this setting ?

Thx

Thanks for the answer, but I can't figure how to do it.
If I edit the /etc/network/interfaces file to add this line (up /sbin/ip link set enp0s3 promisc on), the promiscuous mode is enabled after a reboot.

As you're not supposed to manually edit this file, I tried to create a /etc/network/interfaces.d/promiscuous file and put the same line in it, but it doesn't enable promiscuous mode after a reboot.

/etc/network/interfaces :

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).


source /etc/network/interfaces.d/*


# The loopback network interface
auto lo
iface lo inet loopback


# The primary network interface
allow-hotplug enp0s3
iface enp0s3 inet dhcp
#up /sbin/ip link set enp0s3 promisc on

/etc/network/interfaces.d/promiscuous :

up /sbin/ip link set enp0s3 promisc on

Nevermind, what I tried below doesn't work
I found a way to make it work, though I'm not sure that's the better way to do it :
Keep the /etc/network/interfaces file as-is.
Create a /etc/network/interfaces.d/promiscuous (or whatever name suits you) and write inside :

iface enp0s3
up /sbin/ip link set enp0s3 promisc on

After a reboot, promiscuous mode is on.
Replace enp0s3 with your interface name.
