RE: starting eth without IP address
I'd got the same question and the most elegant way that I've found is to start it in another script, not in "networking", for example /etc/init.d/eth1 

#!/bin/bash

case "$1" in
 start)
       /sbin/ifconfig eth1 up
   ;;

 stop)
       /sbin/ifconfig eth1 down
   ;;
 *)
   echo "Usage: /etc/init.d/$NAME {start|stop}"
   exit 1
   ;;
esac

and make an update-rc.d eth1 defaults 10.

I don't know if this way is the debian way but sure it's a linux way ;-)

Subject: starting eth without IP address
Date: Thu, 20 Oct 2005 11:00:56 +0300

Hi list,
I have a sarge system with two NICs. I want to start eth1 without an IP address and with no ARP running, so as to use it just for sniffing. I can't figure out how do that.
Nothing I tried putting in /etc/network/interfaces works. The net startup script always complains about missing configuration and of course eth1 isn't started. As a temporary solution I added a 'ifconfig eth1 up' line in /etc/init.d/networking but I really don't like this approach. I don't think that it's even the right thing to do cause of upgrade issues. 

Is there a more elegant solution? What is the debian way?

Any help much appreciated,
thanx in advance!
