[Samba] Share disconnect after inactivity

[Andreas Schlager]

Hi list,

I've the strange problem, that after some time of inactivity a share is
being disconnected. This leads to a red 'X' in the Workplace's list of
connected drives. When opening a disconnected drive, the drive is being
reconnected.

BUT: This has a very fatal side-effect: When f.e. an MS-Access database
is open and the user does not use this db, the share is also being
disconnected. The connection is not restored, when the user works again
in the access-db.

My question: Is this a windows-behaviour or is this from the samba? The
disconnected drives (marked with the red 'X') I can see also on machines
connected to a Windows PDC, but no problems with access occurs there.

Many thanks in advance!

look to "deadtime" option in smb.conf(5)

Hi Dimitriy,

deadtime is set to "0" (= default value).
Maybe the documentation is wrong here?? (it says: "A deadtime of zero
indicates that no auto-disconnection should be performed.")

Or could it be a problem in the implementation? I've googled around and
found that windows servers (NT4 and above) have a default disconnect
time from 15 minutes. But with a windows server this wasn't a problem
for me at any time.

Regards,

-Andreas.

Try use 30 min. In this case we can understand -- is this option work.

AFAIK, connection can be closed from server and from client.
Possible, you need tune your clients machines. Not samba server.
