i have instaled suse 8 and one network card with ip 192.168.0.80/255.255.255.0
I wish to add another ip (an external one 213.157.185.197) to this network card.
I did with
ifconfig eth0:0 213.157.185.197 netmask 255.255.255.248 broadcast 213.157.185.199

and it worked for a moment.
I reboot-ed the station and now i have only the old 192.168.0.80 ip

here it is the:

--ifconf

I expect suseconf just overwrites the settings on boot. You'll need to use Yast2 to set the 2 cards up.

i have a realtek 8139 network card.
i had tried with yast2 to add a new ip for the nethork card but no work.
If i do add... the a new eth1 will be instaled.I choose from the list realtek 8139 but it will not work.
if i check the /etc/module.conf i can see that eth0 use 8139too and the eth1 use RTL8139.
I don't understand why are those different since it is the same network card.
so...yast2 =no good for me ;-(
