[Samba] Multiple IP addresses in DNS record

[Jarrod Hyder]

I have a samba server running on Linux that has two ethernet cards (eth0 &
eth1) that are bonded into a single virtual interface (bond0). This virtual
interface is connected to the corporate LAN and I have another ethernet card
(eth2) that is connected to another server that is used for making
incremental backups. The problem that I am having is that no matter what I
do, the command "net ads dns register -P' causes both the bond0 and eth2 IP
addresses to show up in the DNS record on the corporate domain controller.

I have tried to force samba and winbind to use "interface = bond0" and
"bind interfaces only = yes" and it doesn't seem to help this situation.

If anyone can shed some light on what I am doing wrong, I would really
appreciate it.

BTW, I am using samba 3.0.28a

Jarrod,

Not sure how much help I can be, but give this a try - add the -d # flag
to your 'net ads dns ...' command where # can be something up to 10
(more debug output). This can at the very least confirm the smb.conf
file being read as well as perhaps point you in a better direction. If
nothing else, posted the somewhat cleansed output here; it may help
others here to see where your problem lies.



Regards,
Frank

Here is the debug output of "net ads dns register -P -d 10". I can't really
make heads or tails of it, but I also don't see either of the IP addresses
that are getting registered on the domain. If you could take a look at it I
would really appreciate it.

I fixed a bug recently that prevently :"net ads dns register" from
honoring the "interfaces" line in smb.conf. The fixed only went
in to the v3.2 and later branches. If you need a backport to the 3.0
tree, let me know.

Jarrod,

The above snip was the line I was looking for, and had been hoping to
see more than one line added. Meanwhile, back at the ranch, I see that
Jerry has already responded that this was a bug that was fixed.

Regards,
Frank

Jerry,

If you could create a patch for 3.0.28a that would be great.

Our server is running an older distro and I'm not sure when I would have
time to try to compile 3.2. I think if I could patch the source for the
version we are currently using and recompile it, I would be better off.

Thanks!
