Samba: after update from Mint 18.3 to 19, Windows cannot access Samba shares

A_UK_LinuxUser · 07-08-2018, 02:37 PM

Windows 8.1 x64
Linux Mint x64 Cinnamon
Samba 4.7.6

The Windows machine and the Linux machine can ping each other, both by (static) IP and by hostname.

Windows opens a credentials window for each of the Linux samba shares, but rejects any credentials I supply.

I have this in log.samba:

Code:

[2018/07/08 17:51:23.534753,  0] ../source4/smbd/server.c:448(binary_smbd_main)
  samba version 4.7.6-Ubuntu started.

[2018/07/08 17:51:23.561679,  0] ../source4/smbd/server.c:600(binary_smbd_main)
  At this time the 'samba' binary should only be used for either:
  'server role = active directory domain controller' or to access the ntvfs file server with 'server services = +smb' or the rpc proxy with 'dcerpc endpoint servers = remote'
  You should start smbd/nmbd/winbindd instead for domain member and standalone file server tasks
[2018/07/08 17:51:23.561859,  0] ../lib/util/become_daemon.c:111(exit_daemon)
  STATUS=daemon failed to start: Samba detected misconfigured 'server role' and exited. Check logs for details, error code 22

I have a VPN on each machine, and a software firewall on each machine (and a Router firewall, and an ISP firewall) but I have the problems even with most of that (VPNs, software firewalls, router firewall) disabled.

I'd really appreciate any help.

Are you using active directory?

What are the contents of /etc/samba/smb.conf?

Are the shared directories properly configured to be shared?

Samba error 22 means Samba is misconfigured: https://askubuntu.com/questions/4270...valid-argument

Please surround any terminal output with "code" tags, which become available when you click the "Go Advanced" button beneath the "compose post" window.

Thank you for the reply.

> Are you using active directory?
No - the error I reported seemed to suggest I should be. But that error has no disappeared, to be replaced by one that complains about being unable to 'sync browser lists', though the problem is intermittent and may be unrelated to the lack of connection that I reported.

What are the contents of /etc/samba/smb.conf? Here.

> Are the shared directories properly configured to be shared?

Well, the single user the smb.conf file assigns to them does have full rights over them.

Investigating now.
