Hai, This bug is related to these to settings. bind interfaces only = Yes interfaces = lo eth0 As tested by the user, remove these, and you done have start problems. The other fix is : bind interfaces only = Yes interfaces = 127.0.0.1 YOUR_IP_HERE Related to systemd startup, maybe, but ive seen this as of samba 3.6.x 4.1.x 4.5.8 ( on debian, not tested on ubuntu ) I've not tested 4.6.5 packages from unstable on this yet. imo, its related to the "network interface resolving" and/or startup of debian, not samba itself. but i've never found they why and where. I hops this helps you guys. Greetz, Louis
