Error changing interface name

natepad · 2015-02-25 19:44:36

Hello everyone,

i got this errors when I boot my system:

Feb 25 20:14:05 natepad systemd-udevd[176]: Error changing net interface name 'eth0' to 'enp0s25': Device or resource busy
Feb 25 20:14:05 natepad systemd-udevd[170]: Error changing net interface name 'wlan0' to 'wlp3s0': Device or resource busy

I use connman and I know, that connman sets the interfaces to eth0 and wlan0. But I can't figure out, which other unit wants to override the interfaces.

The output of 'systemctl -t service' is:

What makes you think connman changes the names of the interfaces?

natepad · 2015-02-25 20:43:31

I read it somewhere, but I can't find the link at the moment. Maybe that is not the case. It will actually not change the error messages, because something will change them anyway away from eth0 and wlan0.
And as I know, connman sets them to eth0 and wlan0, thats the reasen why they are busy. That's just what I can remember out of my head and would be logic for me.

That error suggests a udev rule to me... What is in your /etc/udev/rules.d/?

Nothing in there.
