That should not be the case.  The upstart configuration says *to start nmbd
when the network comes up.*  Please put the nmbd.conf back in the correct
configuration, boot with '--verbose' on the commandline, log in, and attach
the /var/log/syslog.conf that results.

Why would nmbd start before your network is up?

Because:

 - nmbd is only needed for operations in some environments, so smbd should
   not block on nmbd being ready before starting
 - nmbd *must* wait for a broadcast-capable network interface to come up
   before it's started, otherwise it will fail - so it can't use the same
   start condition smbd currently does.

The same was reported to Debian as well and looks like it is the same
timing problem: http://bugs.debian.org/576415

I'm just discovering the long story of that LP#462169. It apparently
got fixed in some Ubuntu packages and just forgot flowing "upstream".

If only I could find the patch in LP, it could be added to the Debian
package but that bug is...ahemquite hairy. I get gazillion
informations about the people who are subscribed to the bug but no
obvious point that says *this is the fix*.

This bug is fixed in both karmic and lucid.  If you have not yet installed
the updated samba package from karmic-updates, you should do so.  If you
have the current karmic-updates or lucid version of samba installed and are
still having problems, you have a different bug and should file a separate
report.

This bug in no way would cause such symptoms.

[theozzlives]

have you tried: sudo /etc/init.d/samba start? This is not meant for a
production server we're only in Alpha 2. I have to issue the previous
command in order for my laptop to be seen by my other computers. the
bookmark idea was to see other computers. I hope this helps.

It's not supposed to have been solved in 3.4.0-3ubuntu5.1.  The fix is in
3.4.0-3ubuntu5.3, present in karmic-proposed.

I can also confirm that while I'm running 3.4.0-3ubuntu5.1 the issue hasn't
been solved either.

After booting, running /etc/init.d/samba status shows nmbd not running.

The use of 'wins' here suggests you may have a different bug.  Please
provide the /etc/samba/smb.conf and /var/log/samba/log.nmbd from this system
as well (after setting log level = 3) - preferably attaching these to your
original bug, bug #487795, so if we find ourselves unmarking that bug as a
duplicate, all your information stays with it.

So far, the only way I can reproduce any failure at all is if the loopback
interface is also down, and no interfaces line is set.  That would appear to
be a duplicate of bug #461725; and furthermore it produces an entirely
different error message in the log:

 [2009/12/09 15:16:37,  0] lib/interface.c:527(load_interfaces)
   ERROR: Could not determine network interfaces, you must use a interfaces 
config line

and causes smbd to fail to start *in addition to* nmbd.  So this doesn't
match the bug report of the original user.

It looks like I'm still missing here a complete set of:

 - description of which server processes fail to run
 - copy of /etc/samba/smb.conf
 - copy of /var/log/samba/log.nmbd (with log level = 3 set)
 - copy of /etc/nsswitch.conf
 - copy of /etc/resolv.conf

from *the same* user.  Until I have all of these things (preferably from the
original submitter, with other people experiencing problems filing their own
bug reports so that they can be tracked separately if it's *not* the same
bug), I don't think I'm going to make forward progress on resolving this.

The bug being tracked here is specifically related to the nmbd server not
starting.  Can you please confirm that your boot-time start error has the
same log output as Alain's in
,
using 'log level = 3' in /etc/samba/smb.conf?  Your description of what
you're seeing makes me think it may not be the same problem.
