Assign Static IP to SUSE Installation

Assigning a Static IP

Login to your SUSE server via SSH and run the following command:

nano /etc/sysconfig/network/ifcfg-eth0

This will load the file that contains the configuration options for eth0. You will see something similar to this:

BOOTPROTO='dhcp'
BROADCAST=''
ETHTOOL_OPTIONS=''
IPADDR=''
MTU=''
NAME='AMD PCnet - Fast 79C971'
NETMASK='255.255.255.0'
NETWORK=''
REMOTE_IPADDR=''
STARTMODE='auto'
UNIQUE='rBUF.weGuQ9ywYPF'
USERCONTROL='no'
_nm_name='bus-pci-0000:02:00.0'

In order to switch from DHCP to a static IP address, we need to change a few of these values. In the following example, you will need to change the values so they match your network:

BOOTPROTO='static'
BROADCAST='192.168.168.255'
ETHTOOL_OPTIONS=''
IPADDR='192.168.168.221'
MTU=''
NAME='AMD PCnet - Fast 79C971'
NETMASK='255.255.255.0'
NETWORK='192.168.168.0'
REMOTE_IPADDR=''
STARTMODE='auto'
UNIQUE='rBUF.weGuQ9ywYPF'
USERCONTROL='no'
_nm_name='bus-pci-0000:02:00.0'

In this file, we changed the following configuration options: BOOTPROTO, BROADCAST, IPADDR, NETMASK (if applicable), NETWORK (if applicable). Leave everything else as is. Once you have updated this file to reflect your network settings, save the file by hitting Ctrl-O and then exit nano by hitting Ctrl-X. Now we need to restart the network service by running the following command:

service network restart

Once the service has been restarted run ifconfig and make sure the IP address has been assigned to the adapter.
