samba - Jun 2017 - [4.2.14-Debian] Smbd not listening on 192.168.0.x on cold start

Hello,

I noticed a problem when cold-starting a Debian host: smbd doesn't listen on
192.168.0.x. I need to restart it through the Initd script:

Forgot to give the smb.conf:

=========root at debian:~# cat /etc/samba/smb.conf
[global]
workgroup = WORKGROUP

log level = 2

;this avoids needless errors in the logs if you have no printer
printcap name = /dev/null
load printers = no
printing = bsd

security = user
hosts allow = 127.0.0.1 192.168.0.0/24
hosts deny = 0.0.0.0/0
bind interfaces only = yes
;added to investigate issue with Net'hood
interfaces = eth0 lo

map to guest = bad user

;Remote Samba host acting as WINS server
wins server = 192.168.0.15

;Added to investigate issue "At this time the 'samba' binary should
only be
used for either"
server services = +smb

[write]
path = /mydir
guest ok = yes
writeable=yes
browseable=yes

OK, it looks like you are trying to set up a standalone server with
guest access, I suggest you read this wiki page:

https://wiki.samba.org/index.php/Setting_up_Samba_as_a_Standalone_Server

You do not need most of the parameters you have added to smb.conf, you
most definitely don't need this one:

server services = +smb

This should only be added to a smb.conf on a Samba AD DC and only then
if you had been using the deprecated (and now no longer built by
default) ntvfs code.

You should also investigate why this is happening:

[ ok ] Restarting samba-ad-dc (via systemctl): samba-ad-dc.service.

This is probably being done by the 'samba' init script, but it
shouldn't, it should be that the 'samba' init script starts the
'smbd' &
'nmbd' binaries or 'samba-ad-dc' starts the 'samba'
binary. If your
'samba' init script tries to start all the binaries I have mentioned,
I would class this as a bug.

I would not worry about your samba standalone server not listening on
'192.168.0.7' ports 139 & 445. The Unix domain member I am typing
this
on doesn't either and I have never noticed any problems.
