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.
