Using nmbd without smb for browsing

Thu Apr 18 16:46:29 GMT 2002

Hi,

If you want Samba to act as a browse master then you need to be running
smbd. The way that it works is that nmbd will collect the browsing
information and write it to the browse.dat file. When a client wants to
retrieve the browse list it will connect to the IPC$ share on the machine
and issue a request to receive the browse list, thus requiring smbd to be
running. Smbd will then read the browse.dat file to server this information.

Note that this is a completely separate function from being a WINS server.
Without smbd running you will not be able to browse, but you should still be
able to access the computer by name, e.g. by typing \\machine in the Run
dialog box.

Cheers,

Martin.

Subject: Using nmbd without smb for browsing

Hi all,

I would like 2 "Windows" PCs connected with PPP to a linux box to share
their 
files and printers using netbios.

The linux box doesn't have to appear in the "network neighbourhood".
So I run nmbd (and NOT smbd) in the linux box with the appropriate options
in 
smb.conf to be a wins server and to be the domain browse master and local 
browse master (as I saw in the file "browse.txt" in the docs).

One of the "Windows PC" is an XP computer. On this machine in the 
neighbourhood I see the workgroup name a entered in smb.conf (MY_WORKGROUP),

but I can't browse it. The name resolution looks good though (I can ping the

windows name of the linux box).

In the tcpdump on this connection, it looks like the client sees the linux 
box (BLUEDSL), and the try to connect to a TCP port (that would probably be 
handled by smbd if it were here).

Is there any chance I could make this configuration work ? Is anyone 
interested in having more logs/config files ?

Regards,

David.

ps :

I use samba  2.2.3a and  the linux box is based on an ARM processor, linux 
2.4.17.
tcpdump on the linux box :
