Samba needs to be stopped and restarted in order to work

This behaviour was observed in Ubuntu 11.10 too.

Thanks for taking the time to report this bug in Ubuntu.

I've seen similar issues when using the following configuration:

  bind interfaces only = yes

This causes samba to only bind to selected interfaces rather than 0.0.0.0 - as it starts early in the boot process this fails as its not guaranteed that all network interfaces have started when smbd does:

  start on (local-filesystems and net-device-up)

When you restart smbd after boot the network interfaces have started so all works OK.

I would suggest that you either reconfigure samba to listen more generically or add a upstart stanza to /etc/init/smbd.override:

  start on (local-filesystems and net-device-up IFACE=eth0)

You will need to change this to fit your configuration - i.e. which network interface provides 192.168.0.0/24. For more information see 'man 5 init'.

I'm going to mark the bug as 'Invalid' as I think its specific to your local samba configuration. If you think this is not the case please comment and mark as 'New'.

Thanks

confirmed on fresh install of ubuntu 12.04TLS, it is definitely not dependent on PArnal's local configuration,
for me even "start on (local-filesystems and net-device-up IFACE=eth0)" did not help
it needs restart of smbd/nmbd after each reboot

This also affects me; I was simply follwing the recommendation, in the configuration file, since my server is also a firewall:

# Only bind to the named interfaces and/or networks; you must use the
# 'interfaces' option above to use this.
# It is recommended that you enable this feature if your Samba machine is
# not protected by a firewall or is a firewall itself. However, this
# option cannot handle dynamic or non-broadcast interfaces correctly.
   bind interfaces only = yes

I forgot to mention that this is on ubuntu 12.04LTS for me as well.

I have also just observed this on my 12.05LTS install as well.

12.04LTS (typo)

This bug is still present in 14.04 LTS. Putting the following line in /etc/init/smbd.override solves it for me:

start on (local-filesystems and net-device-up IFACE!=lo)

(Putting this line in /etc/init/smbd.conf also works of course.)

Why can't this line be included in the standard smbd.conf that ships with Ubuntu? The only downside I can see is that on computers which only have a loopback interface, Samba will not start. But why would someone want to use Samba in such a configuration?

By the way, this bug seems to be a duplicate of https://bugs.launchpad.net/ubuntu/+source/samba/+bug/951087
