Stop nmbd from listening on external interface?

Question

I've installed a Mac mini (with OS X Lion Server) as a file server and  local gateway between my organization's local network and ISP's private network.
Issues with NAT and DHCP are separate, and not much of an immediate concern for now, but the nmbd acting up on the local network is a real stopper.
The connection scheme is as follows:
My LAN is connected to en0 (internal Ethernet port) and is located in Apple's idiotic 192.168.2.0/24 range (for now).
The ISP network is somewhere in the 10/8 range and is connected to en3 (USB Ethernet adapter)
In system settings, own LAN (en0) is set above all else.
The problem is that if Mac's nmbd winning election and become a responsible name server, the name resolution in the workgroup fails with "no route to host" message, until I turn on any MacBook located in the same workgroup, which winning election over the server.
When i make a check with server itself, it's SMB name (and the <name>.local alias) is always resolved to the address of external (en3) adapter.
The question is - how to tell this idiot to do the right thing and stop acting like it have a brain?

Answer 1

I am sure that there is a better way to do this using the /etc/X11/nvidia.conf file, but I am not very familiar with that one. The way that I am familiar is to put this line at the top of the session file that startx uses:
disper -s
Note that I am not backgrounding it using the '&'. You do not want to do that because then the script will hang until the display switch complete. You also want to put it before the conkys because then the display switch happens before conky is started.
I face similar issues with dzen and trayer. I get around it by using the following bash script to determine the screen sizes:
#!/bin/bash
OUT=$(disper -p 2> /dev/null )
NUMBER=$(( ${1:-1} + 1 ))
MONITOR=$(echo "$OUT" | sed -e '/xinerama/!d' \
-e 's/[a-z ]*: //' \
-e 's/$/,/' \
-e 's/[A-Z0-9-]*,/|&|/'$NUMBER \
-e 's/,//g' \
-e 's/[^|]*|\([A-Z0-9-]*\)|.*/\1/')
source <(echo "$OUT" | sed -e '/metamode/!d' \
-e "s/$MONITOR: nvidia-auto-select @\([0-9]*\)x\([0-9]*\) +\([0-9]*\)+\([0-9]\)/|W=\1;H=\2;X=\3;Y=\4;|/" \
-e 's/[^|]*|\([0-9XYWH=;]*\)|.*/\1/')
case $2 in
w) echo $W ;;
h) echo $H ;;
x) echo $X ;;
y) echo $Y ;;
*) echo "X=$X"
echo "Y=$Y"
echo "W=$W"
echo "H=$H"
esac
I am sure that the script could be improved upon, but that's how I take care of it.
Just out of curiosity, does your disper function properly? Mine stopped working a couple weeks ago.
