Suse 8.2: Setting up an ethernet-interface without an ip-address

Because of setting up Suse 8.2 for Snort I want to set one of the
ethernet-interfaces in promiscuous mode. Which is not the problem ;-)

The problem is I want to setup this ethernet-interface without an
ip-address.

Setting up with an ip-address works fine.

================================================== ========================

Using Suse 7.2 this was very easy using /etc/rc.config:
#
IPADDR_0=""
#
NETDEV_0="eth0"
#
IFCONFIG_0="up"
#

================================================== ========================

Now I have to use /etc/sysconfig/network/ifcfg-eth0:
BOOTPROTO='static' # dhcp or static, none (and bootp) are not
supported
BROADCAST=''
IPADDR=''
MTU=''
NETMASK=''
NETWORK=''
REMOTE_IPADDR=''
STARTMODE='onboot'
UNIQUE=unique number
WIRELESS='no'

================================================== ========================

/var/log/boot.msg says:

eth0 ERROR: Warning: Could not set up default route via
interface eth0


Please advise,
Xantos

I fear you have to hack the scripts for supporting none, or
you have do have your own script which is doing the ifconfig
for you.

But why aren't you asking SuSE themselves?

You are trying to setup the default route via interface without IP
address. This doesnt work. What you need to do is to delete GATEWAY ip
address.

I would like to, but I added only a default ip adress which should be
routed via eth1. Any idea how to delete GATEWAY ip for eth0?

Kind regards,
