Hello,
As subject says I am working on browsing and access servers, which
are dispatched on two subnet, in one workgroup named "WORKGROUP".
First here the network :
( I don' t use ASCI art 'cause I am not an expert on that and it may not
be printed as it was emailed. )
So, there is five machine :
- one, under debian 6, which is the gateway
- two, under debian 6, samba server => one per subnet
- two, under windows xp sp2, "client"
and two network :
- 192.168.52.0/24
- 192.168.53.0/24
The gateway is very simple, it just a fresh minimal install from a
debian 6.0 business card CD with two network interface and the sysctl
"net.ipv4.ip_forward" set to "1" in sysctl.conf.
No firewall is running on this gateway so all packet (except broadcast)
from subnet 1 to subnet 2 pass through and vice versa (tested with ping
command).
His IP address are 192.168.52.254 for subnet 1 et 192.168.53.254 for
subnet 2.
The two samba server :
Both of then are fresh installed as the gateway but with only one
network interface.
Samba was installed with debian package and version is 3.5.6
IPv6 has been disable on those server with this method
(wiki.debian.org/DebianIPv6#How_to_turn_off_IPv6) => /echo
net.ipv6.conf.all.disable_ipv6=1 > /etc/sysctl.d/disableipv6.conf/
They don' t server any printer or file share, configuration file include
only "global" section.
WINSGW is the wins server, domain master browser, local master browser.
WINSGW2 is only local master browser.
Des conseils sur : interfaces, remote announce, remote browse sync
I understand this, may be I get it wrong !
Local Master Browser is the computer on each subnet which manage a
list of computer by the help of broadcast message from all other
computer on the same subnet. But it don't "share" this list.
Domain Master Browser (WORKGROUP#1B) is used to share this list of
computer for each workgroup and is also a local master browser for his
subnet (if their isn't an other).
Any LMB must talk to this DMB to sync their browse list.
WINS server is used to resolve NetBIOS Name and their should be
only one for the whole network.
Only port 137, 138 and 139 are used to browse and get IP address.
So when client boot up send using brodcast their server announcement
(share, messenger, user logged) on the local subnet and the LMB
interpret them.
After they give their IP address to the WINS server.
With no wins server (nor xp client, nor samba configuration) used each
subnet can see (browse) and can access (sahre) all other computer on the
same subnet.
Now, the idea is to make computer on each subnet must see computer on
the other one with the help of WINS and master roles.
I don't make this works.
I don' t know where to place "remote announce", "remote browse sync" and
which parameter for each and I am not shure about "wins support", "wins
server" and '"interfaces".
"interfaces" only contain local IP, or they must contain network address
of each subnet where the workgroup is ?
In my case WINSGW2 can' t solve WORKGROUP#1B (DMB) to an IP address and
can' t sync his browse list.
Does the wins server should not run any king of master browser ?
It seems that query a wins server about himself don' t generate answer.
I would get advice about previous parameters to understand what they
means, should done and how.
Does any one has ever worked with this kind of architecture ?
Thank you.
Here extract of the log on WINSGW2 :

The two XP are fresh install (no any additional software) and the
windows firewall is disabled on both.
