[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: =========May 17 11:56:02 debian systemd[1]: Stopping LSB: start Samba NetBIOS nameserver (nmbd)...

Can you post the init script ? Rowland

It looks like the update enabled a systemd service that starts the "samba" binary - which is the Samba AD DC. Because your config is not for a DC, Samba logs this error. * Disable the samba and samba-ad-dc services * Enable the nmbd and smbd services Regards, Marc

that init script is ok.
Try adding the following in your smb.conf
Add :
interfaces = 192.168.249.230 127.0.0.1
Or interfaces = eth0 lo
( change eth0 to your interface name)
Check:
systemctl status samba
systemctl status samba-ad-dc
If samba-ad-dc is enable, disable that one, and enable samba.
systemctl disable samba-ad-dc
systemctl enable samba
