I have a samba file server that I created about 20 years ago and in the time I have done the little updates needes to new server (when I move to a new server I copy config and adapt if needed). It only do public file sharing. Some week ago a client stopped to connect to the share. Only this client (Win 10 updated to 1703 or 1709). It can connect to other windows shares or linux samba shares, but not to this server.. Any attempt end in a messagge like "can't connect to \\GWLAN check ortography ..." (translation from Italian original message) After many attempt, I reformatted and reinstalled the client from scratch. Now the problem is still present: this client can't connect to the shares. It connect to every other box in the LAN, but not to this box. I can't find any useful info in the server's logs, but I noticied a strange report from the smbstatus command: Samba version 4.5.12-Debian PID Username Group Machine Protocol Version Encryption Signing -------------------------------------------------------------------------------------------------------------------------------- 12620 mondo mondo 192.168.67.5 (ipv4:192.168.67.5:51969) SMB3_11 - - 12620 mondo mondo 192.168.67.5 (ipv4:192.168.67.5:51969) SMB3_11 - - 12620 mondo mondo 192.168.67.5 (ipv4:192.168.67.5:51969) SMB3_11 - - 12620 mondo mondo 192.168.67.5 (ipv4:192.168.67.5:51969) SMB3_11 - - 12620 mondo mondo 192.168.67.5 (ipv4:192.168.67.5:51969) SMB3_11 - - . . .

It works fine and don't show any symptoms of problem. Like all other clients. The not working client is the 192.168.67.204 (not listed) That can connet to other samba servers or windows shares. No DC in this LAN. only workgroup. If I restart samba the 65534 rows disappear but after few hours I can noticied them again in smbstatus report. 65534 is so close to the 65536 magic number that I can't think it is a coincidence :-) My smb.conf: ============================================================================[global] workgroup = APF server string = APF Server Version %v netbios name = GWLAN interfaces = lo eth0 192.168.67.254/24 hosts allow = 127. 192.168.67. log file = /var/log/samba/log.%m max log size = 5000 guest account = mondo security = user map to guest = bad user passdb backend = tdbsam load printers = no cups options = raw [homes] comment = Home Directories browseable = no writable = yes [printers] comment = All Printers path = /var/spool/samba browseable = no guest ok = no writable = no printable = yes [share] writeable = yes public = yes path = /DATA/HOME/share/public guest ok = yes comment = Area Condivisa read only = no writable = yes printable = no inherit permissions = yes create mode = 0664 veto files = /.flexshare*/ recycle:repository = .trash/%U recycle:maxsize = 0 recycle:versions = Yes recycle:keeptree = Yes recycle:touch = No recycle:directory_mode = 0775 vfs object = recycle:recycle [hidden$] comment = Area Condivisa path = /DATA/HOME/public/hidden read only = no writable = yes printable = no inherit permissions = yes create mode = 0664 guest ok = yes public = yes only guest = yes [condiv] guest ok = yes public = yes only guest = yes comment = Area Condivisa Spool path = /home/mondo read only = no writable = yes ============================================================================ Are these things related?

I reinstalled the box and worked fine for a couple of weeks (this box is only used about twice for week). I have about 10 other boxes with windows 10 that works without problems (some always on other sporadic guests). Like the 2016 boxe (that seems to generate the other "problem" of the 65534 rows in the smbstatus report). And some Win 7, Win XP, ... Anyway, tried your hint. No difference for the specific win 10 client. Still can't connect. All other Win 10 and the 2016 tested still works as usual. smbstatus still reports the "strange" rows: Samba version 4.5.12-Debian PID Username Group Machine Protocol Version Encryption Signing ---------------------------------------------------------------------------------------------------------------------------------------- 6358 mondo mondo 192.168.67.5 (ipv4:192.168.67.5:58761) SMB3_11 - - 6358 mondo mondo 192.168.67.5 (ipv4:192.168.67.5:58761) SMB3_11 - - 6358 mondo mondo 192.168.67.5 (ipv4:192.168.67.5:58761) SMB3_11 - - . . . but only 16650 (until now). The only real difference is that a couple of old VMs with win 98 (yes there is the need to keep them alive), now can't connect to the server :-) Thanks, B.
