samba - Jul 2005 - Samba File Server with 2 NICs, only one is used

Hello all,

We have a Mandrake 10.1 server with Samba 3.0.13. The box has 2 NICs,
2 IPs and our DNS servers have both entries (same name for 2 IPs).
Since kerberos is not working around here (tried to fix it for about 3
weeks, then gave up) I found my workaround: I use NetBIOS alias for my
server, all clients use this alias for samba access and they
authenticate thgrough SSPI.

My problem is that only one of my NICs seems to work :

ifconfig | grep RX\ bytes gives:

          RX bytes:2906637535 (2771.9 Mb)  TX bytes:4256133463 (4058.9 Mb)
          RX bytes:13805476 (13.1 Mb)  TX bytes:546 (546.0 b)
          RX bytes:151532631 (144.5 Mb)  TX bytes:151532631 (144.5 Mb)
(last line is lo)

This data is after 8 days of heavy usage...

Any hints?

smb.conf:

        workgroup = XXX
        realm = XXX.LOCAL
        netbios aliases = YYY
        server string = Samba Server %v

        idmap uid = 10000-20000
        idmap gid = 10000-20000
        template shell = /bin/bash
        winbind use default domain = Yes
        valid users = @ZZZ
        create mask = 0760
        hosts allow = 192.168.254.0/255.255.255.0
        hide files = /.*/desktop.ini/thumbs.db/

TIA

It caused havoc on my system, I used 1 for Samba, 1 for DHCP & DNS..  
on the same subnet...
It really didn't help system performance, and just caused confusion  
in the log files...

I believe the Best Practice, is to have 2 separate subnets, on those  
2 cards. In & Out or 2 different Inside Subnets...

2 nic's on the same subnet?
I have been told that this will not work. And to type "route" to see 
why.

Seems to me that you could use Linux's ethernet bonding support if the
switch the machine is connected to supports port trunking.
