Here is some additional information that I could gather over this problem: - smbstatus from samba 4.3.1 also shows the Protocol version from connected clients:
root@vdebian:~# smbstatus -v using configfile = /usr/local/samba/etc/smb.conf Samba version 4.3.1 PID Username Group Machine Protocol Version ------------------------------------------------------------------------------ 733 client1 clients 192.168.1.21 (ipv4:192.168.1.21:57591) Unknown (0x0311) Opened /usr/local/samba/var/lock/connections.tdb ... Unless I force Win10 to use SMBv1 it talks to samba with SMBv3 and in this case smbstatus reports "Unknown (0x0311)". Otherwise (with SMBv1, an XP- or Linux-client) it shows a correct Version like "NT1". Also see https://bugzilla.samba.org/show_bug.cgi?id=11472 - When using the -v option with smbstatus, it prints the line "Opened /usr/local/samba/var/lock/connections.tdb". When I browse this directory and look for connections.tdb, the file simply does not exist. - The problems as shown above only occur when a Windows-client connects via SMBv2/3 (e.g. Win7/8/10) to Samba 4.1.x (maybe also 4.0.x, I haven't testet yet). So in my layman's terms I would explain it like this: on the one hand it's the clients fault when it doesn't tell to the server to release locked files. Maybe SMBv2/3 uses some faulty functionality that is completely ignored by Samba 3.x and therefore causes no issue - other than Samba 4.x. On the other hand the server should be able to detect dead connections and close them after a while since there is a chance that the client lost the connection unexpectedly or because of external reasons. ** Bug watch added: Samba Bugzilla #11472 https://bugzilla.samba.org/show_bug.cgi?id=11472 -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in Ubuntu. https://bugs.launchpad.net/bugs/1392647 Title: smbstatus reports dead connection as active To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1392647/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
