Macchanger stopped working on boot

For a while now I have had macchanger run on boot, as per the wiki instructions.

This is my /etc/systemd/system/macspoof@.service:

[Unit]
Description=macchanger on %I
Wants=network-pre.target
Before=network-pre.target
BindsTo=sys-subsystem-net-devices-%i.device
After=sys-subsystem-net-devices-%i.device

[Service]
ExecStart=/usr/bin/macchanger -e %I
Type=oneshot

[Install]
WantedBy=multi-user.target

This is the error being reported:

systemctl status macspoof@wlp1s0
● macspoof@wlp1s0.service - macchanger on wlp1s0
   Loaded: loaded (/etc/systemd/system/macspoof@.service; enabled; vendor preset: disabled)

Oct 25 06:04:09 george systemd[1]: macspoof@wlp1s0.service: Failed with result 'exit-code'.

The "interface up or insufficient permissions: Device or resource busy" makes me think this is being run after the wireless has already started up, but from the wiki the line Before=network-pre.target line should prevent that.

It worked well in the past and it also works just fine if I run it manually. It just doesn't run on boot anymore. Any ideas?

Thanks

Re: Macchanger stopped working on boot

If you use NetworkManager you need to read: https://blogs.gnome.org/thaller/2016/08 … ger-1-4-0/
According to that I suppose you shouldn't need macchanger anymore. I was thinking it may somehow be related to your problem even if you don't use NetworkManager.

Hope it helps.

Re: Macchanger stopped working on boot

Thanks but I do not use NetworkManager - I use Wicd instead.
