[Samba] Upgraded > Samba no longer listening on 192.168.0.x




Hello

Since I last ran "apt-get upgrade" on a Debian host which upgraded Debian to
8.8 and Samba to 4.2.14, Samba is no longer listening on the 192.168.0.x
network after waking up from suspend mode. As a result, it's not listed in
Windows' Network Neighborhood and, thus, not reachable from a Windows host
where a backup job is running that uses the Debian host as a file server.

Samba runs as a stand-alone server at home, and is only used to share a
directory, with write access; It handles no printer. This computer only has
one Ethernet card, and is scheduled to wake up and go back to sleep every
day with enough time to be used to run the backup job.

Running "/etc/init.d/samba restart" does solve the problem but I must find
the root of the problem and solve it accordingly.

Here's what /var/log/syslog says when I run the init.d script; Notice the
"At this time the 'samba' binary should only be used for either" at the end:

This is the smb.conf I wrote:
==========
[global]
workgroup = WORKGROUP
;netbios name = LINUX

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

map to guest = bad user

;Sheevaplug
wins server = 192.168.0.15

[write]
path = /BackupFromWindows7
guest ok = yes
writeable=yes
browseable=yes
==========

And I notice that Samba mentions "samba-ad-dc" when running the init.d
script:
==========
root@debian:~# /etc/init.d/samba restart
[ ok ] Restarting nmbd (via systemctl): nmbd.service.
[ ok ] Restarting smbd (via systemctl): smbd.service.
[ ok ] Restarting samba-ad-dc (via systemctl): samba-ad-dc.service.
==========

It used to work fine before upgrading: Do I need to change something in
smb.conf? And should I run add a Cron job to run the init.d script after the
computer wakes up?

Thank you.
