[Samba] Can't access by NetBIOS Aliases or IP Address

Hi all.

I am running Debian jessie server with Samba, which has joined the Active
Directory domain. The domain controllers are Windows Server 2012 R2.

After I upgraded Samba version from 4.1.17+dfsg-2+deb8u2 to
4.2.10+dfsg-0+deb8u2, I'm facing the problem that I can't access Samba
share by NetBIOS Aliases or IP Address.

The Samba's NetBIOS name is mysamba, and I can access by NetBIOS Name from
windows pcs as follows.

net use g: \\mysamba\myshare

But, I can't access by NetBIOS aliases or IP address as follows. (mysamba01
is NetBIOS aliase)

net use g: \\mysamba01\myshare
or
net use g: \\192.168.0.1\myshare

The previous version, 4.1.17+dfsg-2+deb8u2 works fine, and I can access share by
NetBIOS Aliases or IP Address.

Any suggestions will be appreciated.

[Samba] Can't access by NetBIOS Aliases or IP Address

Hm.. standard troubleshooting may be

use smbclient -L on the samba server to list shares and make sure samba is
responding to request.

check the samba logs for info -- and if needed turn loglevel up in smb.conf

if this was a joined server prior to upgrade, you may need to rejoin it to
the domain

[Samba] Can't access by NetBIOS Aliases or IP Address

Hi, David.

Thank you for your reply.

I ran smbclient -L on the samba as follows.

smbclient -L mysamba -U tsuyama -W foo.local

Enter tsuyama's password:
Domain=[SPS] OS=[Windows 6.1] Server=[Samba 4.2.10-Debian]

        Sharename       Type      Comment
        ---------       ----      -------
        IPC$            IPC       IPC Service (mysamba server)
Domain=[foo] OS=[Windows 6.1] Server=[Samba 4.2.10-Debian]

        Server               Comment
        ---------            -------
        mysamba01            mysamba server
        COLUMBUS             columbus server
        mysamba              mysamba server

        Workgroup            Master
        ---------            -------
        foo                  COLUMBUS

COLUMBUS is another samba server.

I set log level to 3. Here is the log for running smbclient -L.

The samba server joined the domain prior to upgrade, and I rejoined it
to the domain. But the issue is the same as before.

[Samba] Can't access by NetBIOS Aliases or IP Address

Hi all.

The problem has been finally solved. Please let me explain how to
solve it.

I just installed winbind package, and the samba server works fine
again.

I don't understand why winbind contributes to fix the problem.


Take care.
