[Samba] 2 nics, browsing

[Stefan G. Weichinger]

I have problems with browsing, AFAI see ...

There are 2 Samba 3.0-hosts in the subnet 192.168.16. called server
and backup. The workgroup is buero.

server has 2 NICs with the ips 192.168.16.200 and 192.168.16.201.
backup has one NIC with ip 192.168.16.112.

server is configured with the options:

local master=yes
preferred master=yes
os type=40

backup with:
os type=20
local master=yes

(to provide backup-browser-service).

interfaces parameter is not set.
I want Samba to use both NICs on server.

testparm runs ok on each host.

Look at these lines:

> server:~ # nmblookup -M buero
> querying buero on 192.168.16.255
> 192.168.16.201 buero<1d>
> 192.168.16.201 buero<1d>
> server:~ #

So I get two answers over the localhost-interface, I assume. Why is it
two times the .201-ip?

If I try the same from backup:

> backup:~ # nmblookup -M buero
> added interface ip=192.168.16.112 bcast=192.168.16.255 nmask=255.255.255.0
> querying buero on 192.168.16.255
> Got a positive name query response from 192.168.16.201 ( 192.168.16.201 )
> Got a positive name query response from 192.168.16.201 ( 192.168.16.201 )
> Got a positive name query response from 192.168.16.201 ( 192.168.16.201 )
> Got a positive name query response from 192.168.16.201 ( 192.168.16.201 )
> 192.168.16.201 buero<1d>
> 192.168.16.201 buero<1d>
> 192.168.16.201 buero<1d>
> 192.168.16.201 buero<1d>

I get four responses ....

Question: Should the backup:/etc/hosts contain both ips of server
like:

192.168.16.200 server
192.168.16.201 server

How should this be handled?

I know this is another topic but has possibly the same reason:

> backup:~ # tail /var/log/messages
> Oct 27 15:20:06 backup sshd[21744]: Could not reverse map address 192.168.16.201.
> Oct 27 15:20:06 backup sshd[21744]: Accepted rsa for root from ::ffff:192.168.16.201 port 46587

Reverse DNS ... I will look that up, I promise ...
I think that

... this ...

> server:~ # tail /var/log/messages
> Oct 27 15:22:19 server nmbd[1318]:   find_response_record: response packet id 19864 received with no matching record.
> Oct 27 15:22:20 server nmbd[1318]: [2003/10/27 15:22:20, 0] nmbd/nmbd_responserecordsdb.c:find_response_record(235)
> Oct 27 15:22:20 server nmbd[1318]:   find_response_record: response packet id 19863 received with no matching record.

... and this ...

... results from the same wrong configuration .

Am I right? What should I do about it?
