Hi,
An easy way to do this would be trhough suse's YAST tool, somewhere you should find the options to set up the network interface, otherwise, follow these instructions -
What follows are the general instructions for configuring an ethernet in a linux distribution (assuming only one LAN card in the system).
1. Login as root in a terminal.
2. Optional step - find out the module used by your LAN card and load it by using "modprobe <module name>".
3. Configure your IP addres.
Code:
ifconfig eth0 10.0.0.203
4. Configure the netmask
Code:
ifconfig eth0 netmask 255.255.255.0
5. Add the DNS entries by opening the file /etc/resolv.conf in an editor (try typing kedit /etc/resolv.conf, or gedit /etc/resolv.conf)
Add the lines of your DNS servers
6. Add the gateway
Code:
route add default gw 10.0.0.1
7. Start the network interface
