[Samba] Cross subnet browsing

Jason C. Waters

I'm having a hard time figuring this one out. I've done this before
when I had a PDC on one end of the VPN, and a BDC on the other. This is
what my setup looks like now.

Clients(XP)
|
PDC(192.168.0.4), windows 2000
|
|
WINS Server Samba(192.168.0.1), also the gateway for this network
|
|
Internet
|
|
WINS Server Samba(192.168.2.1), also the gateway for this network
|
|
Clients(XP)

With this setup I'm not sure how I'm suppose to setup each wins server.
Do I need to have one on each subnet, and then have them both remote
announce and remote browse sync to each other? Or maybe some like
that? When I'm using remote announce, should it be 192.168.0.1 or
192.168.0.0 or 192.168.0.255? Same with remote browse sync, does it
need to be the actual address of the other wins server? or do I just
send it to that subnet? Does anyone have a working configuration with
this setup(Domain on one side of the tunnel and just a workgroup on the
other, both are the same workgroup). All the machines can ping each
others ip, so I know its not a tunnel issue. Thanks for your guys help.

Charles,
The clients behind each gateway, do they point to the local wins
server then? So for the clients on the 192.168.0.0 network, they would
point to 192.168.0.1, where samba is running a wins server and announces
to 192.168.2.255? You have wins server = 192.168.1.50, would I just
have wins
support = yes if its on the same machine? Let me clear up what I'm
trying to say.

Should my network look like this: Option A

Clients on network A(192.168.0.0) have a wins server of 192.168.0.1(the
vpn gateway for them as well as a samba wins server)
192.168.0.1(Samba wins server with these settings, wins support = yes,
remote announce = 192.168.2.255)
192.168.2.1(Samba wins server with these settings, wins support = yes,
remote announce = 192.168.0.255)
Clients on network B(192.168.2.0) have a wins server of 192.168.2.1(the
vpn gateway for them as well as a samba wins server)

Or this: Option B

Clients on network A(192.168.0.0) have a wins server of 192.168.0.1(the
vpn gateway for them as well as a samba wins server)
192.168.0.1(Samba wins server with these settings, wins support = yes,
remote announce = 192.168.2.255)
192.168.2.1(Samba wins server with these settings, wins server =
192.168.0.1, remote announce = 192.168.0.255)
Clients on network B(192.168.2.0) have a wins server of 192.168.2.1(the
vpn gateway for them as well as a samba wins server)

Or this: Option C

Clients on network A(192.168.0.0) have a wins server of 192.168.0.1(the
vpn gateway for them as well as a samba wins server)
192.168.0.1(Samba wins server with these settings, wins support = yes,
remote announce = 192.168.2.255)
192.168.2.1(Samba wins server with these settings, wins server =
192.168.0.1, remote announce = 192.168.0.255)
Clients on network B(192.168.2.0) have a wins server of 192.168.0.1(the
vpn gateway for them as well as a samba wins server)

Thanks for your help

Jason,

Option A is the good way.

You could use remote browse sync according the the manpage since you only have
Samba servers. We have a mixed network here so it is not a solution. So your
configuration could be, anybody correct me if this is wrong :

For the 192.168.0.1 server :
remote browse sync = 192.168.2.1
wins support = yes

For the 192.168.2.1 server :
remote browse sync = 192.168.0.1
wins support = yes

The manpage doesn't mention that WINS is required for remote browse sync,
since it is based on the workgroup master browser. So maybe you don't need
WINS server at all.

I have it setup that way, with the clients behind each gateway to use
the gateway as their wins server. But I can't see them through my
network places. Any ideas? How long does it take to sync? Can I force
it to sync? Thanks for your help.

Jason,

I have seen sync delays of a couple of hours. I don't know any way to force
it. I would suggest to increase the logging level of nmbd to 2 or 3 and tail
-f the nmbd.log file and see what you get.

Ok so I got it working on one side of the vpn. The 192.168.2.0 can see
all the machines on both sides, but the 192.168.0.0 side can't see the
machines in my network places. They are XP Pro machines incase that
makes a difference. The wierd thing is I can ping the machines by name
but can't see them in my network places. The 192.168.0.0 network has a
windows 2000 PDC. Any ideas? Thanks for your help.
