[Samba] macintosh disconnect problem

Hi all,
   We're having trouble with Macintosh clients (at least) being 
disconnected from Samba.  Below is one macintosh console output when 
this happens, filtered by "smb".  (Yeah, maybe some clues are
missing...)
   ATM I don't see anything that stands out in the Samba log file. 
However one thing I don't see in the samba log file is session disconnects.
   Does anyone know how to log disconnects?  I've found one such way on 
stackexchange involving 'postexec' 
https://unix.stackexchange.com/a/478881/275843, but I thought maybe 
there was a log subsection and level which would also work.  (I don't 
want to set log 10 b/c that would generate so much log file it would 
either fill the drive or get rotated out.)

Thanks!
Chad.

It looks like it cannot find/see the share, how are you running Samba ?

Can you please post your smb.conf.

Hello.
I'm seeing them too (see my messages from a few days ago).

> However one thing I don't see in the samba log file is session
disconnects.
Neither do I.
I've skimmed briefly a level 10 log and didn't see anything useful, but 
I'd need to look better before I state this for sure.

However I see smbd crashing on notifications and I'm still investigating 
why and whether the two things are related.
Do you also see crashes?

Also when did this start?
Did you do some upgrade?
Did it work before?

In my case it started when I moved shares from a base 4.8 installation 
to a jailed 4.10.

  bye & Thanks
	av.

Hi Andrea,

The preexec / postexec hooks mentioned at 
https://unix.stackexchange.com/a/478881/275843 work well for this.  I 
see Mac clients disconnecting when they have problems, but haven't yet 
correlated that occurrence to anything suspicous in the log.smbd file yet.

These questions are hard to answer.  I have the suspicion that there is 
more than one problem going on AND my end users have just lived with it 
for awhile.

I need to do more testing before I have enough to go on before using 
someone like Rowland's time. :)

For example, one failure mode is that sometimes macOS (10.13 ,10.15, ?) 
will block access to paths hosted by Samba.  It is most easily 
reproducible if a DFS link is involved.  So far I know this happens with 
Samba 4.9.17, 4.10.11, and 4.11.4 .

Try searching for "finder" and "sandbox" in Console of a
Macintosh which
is having problems.  Press "return" after each term so you're not 
searchign for "finder sandbox" but "finder" AND
"sandbox".

Eventually I'll submit a bug report on that, but need to write it up.

That is not the only problem however.

Chad.
