Re: [Openvpn-users] Netbios + Routing?

I think the dance is something like that:
(or why i'm not a broadcast-slave partner, or even: the half of the hosts
available in Network Neighborhood are just your imagination and try to use
a share and you'll see what i'm talking about).

Suppose you have 2 WINS servers: one in each subnet.

Both are connected with their duplicating partners facilities (all
Win2kServer version around here are pt_BR locale, so, translate it,
please).

SAMBA has a lot of ressources to get connected to it's subnet and to other
WINS servers: remote announce, domain master, name resolv order, and many
more.

The "wins server" parameter is first used instead of broadcast - you can
check yourserlf disconnecting for few moments the wins server and trying
to use some "new" share. Broadcast also plays it's role: this is why we
can use a share without a wins server in a given subnet.

So, suppose you want to print a doc in Brazil from England trough OpenVPN:
Your client connects to the WINS server in the subnet you are (usually).
The wins server in the same subnet range of your host has his "copy" of
lmhosts, with some entries given by the remote wins server, and the share
map is done.
Printing to \\veryremotehost\veryremoteprinter1 is possible, and a
cross-subnet browsing stuff finally works!

This is just a simplistic remote-browse-sync explanation: don't get it too
seriously.

I'm sure you'll have much more fun at http://us1.samba.org/samba/docs/

HTH,


RSalles
