[Samba] samba browsing through subnets with different nethoods
Hi everybody
I installed 2 subnets, one with a samba PDC fully functional and the other
with just
one linux client (called CLIENTE) with samba running a basic configuration.
Subnet 1 has a samba PDC called BAR (domain FOOBAR with ip 192.168.1.1) that
is also the wins
server for both subnets and the domain master browser for 192.168.1.0/24

FOOBAR BAR
Subnet 2 has only a basic funcional samba client (called CLIENTE with IP
192.168.20.2) joined to BAGOLIN workgroup (there's no domain controller)
that is configured to share directories. Its important to say that CLIENTE
is configured to use the wins server that BAR
offers on subnet 1 (and also CLIENTE is the Local Master Browser for
192.168.20.0/24).

BAGOLIN CLIENTE
These 2 subnets are joined with 3 routers as can be seen:
SUBNET 1 (BAR PDC)===192.168.1.0/24===(Router 1)===10.0.0.0/24===(Router
2)===11.0.0.0/24===(Router 3)===192.168.20.0/24===(CLIENTE) SUBNET 2
I made sure that both subnets can be seen each other with no restrictions
(disabled iptables, static routing implementation)
My purpuse is that both subnets can share their browsing lists so I can
access any shared
directory (using any windows workstation) available from both subnets.
I added these options to BAR smb.conf file
remote announce = 192.168.20.2/FOOBAR
remote browse sync = 192.168.20.2
#added earlier
wins support = Yes
and these options to CLIENTE smb.conf file
remote announce = 192.168.1.1/BAGOLIN
remote browse sync = 192.168.1.1
wins server = 192.168.1.1
local master = yes
preferred master = yes
hoping that both samba services can exchange their browse lists, but
unfortunately
the CLIENTE server is still getting only its own browse list meanwhile BAR only
gets
the nethood name:
bar:/var/log/samba # smbclient -L bar -N

BAGOLIN CLIENTE
FOOBAR BAR
if I join a windows workstations to subnet 1 (where BAR PDC belongs) y can see
both
nethoods (FOOBAR and BAGOLIN) but I can't see any computer on BAGOLIN
nethood (at
least should be CLIENTE showing there).
I can ping and even access cliente shares using \\CLIENTE\myshare\ from either
subnets
looking logs I only could get these lines:

as can be seen, CLIENTE is rejecting any attempt to share data with BAR.
I read "Samba how to","samba by example" and google various
sites with no luck.
I'm stuck here, Any tip to solve this problem?
Can samba servers (either Domain master browser or local master browser) share
their browse and nethood lists
along each other through subnets?
thanks in advanced for any suggestions?
