This config is designed to specifically work with IWD. It should work like the original script if you are using ethernet (I made it detect if the interface is wireless or not.)

Needless to say that with the default script it doesn't work either.

Please, please STOP FULL-POST QUOTING. Thank you.

The Kempster,

It would probably help if you pointed to THIS POST so that you don't come off as so offensive when (cough-cough) requesting for people to please STOP FULL POST QUOTING...by explaining that an administrator has requested the same...instead of coming across as an angry man with an agenda of his own.

Hi,
I don't use IWD only interfaces config file.

Did you remove allow-hotplug?

Both auto and allow-hotplug, should I restore auto instead?

Did you make sure not to use IWD's built-in DHCP client?

IWD is not installed!

Did you modify /etc/netplug/netplug?

Yes I did, using the configuration you shared!

I don't actually need the wifi I need it for the eth0, but I guess that if doesn't work is the same for the others, isn't it?

Thanks!

Did you customize the default script?

My WiFi dongle is stuck in a endless loop with your script...

Can you explain a little bit better what you did?

Thanks!

Remove all allow-hotplug and auto lines (except for lo) from /etc/network/interfaces, like this:

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
iface eth0 inet dhcp

iface usb0 inet dhcp

iface wlan0 inet dhcp

Replace /etc/netplug/netplug with all of this:

#!/bin/sh

                # Do the same thing as ifdown (kill dhcp process, etc.) without putting the interface down

    ;;
esac

And replace /etc/netplug/netplugd.conf with this:

eth*
wlan*
usb*

I fixed this by using ifplugd and not using ifupdown's built-in allow-hotplug.

Can you explain a little bit better what you did?

Thanks!

Ifplugd was the only workaround to my problem that I found that didn't involve using NetworkManager.
