To establish an Ethernet connection, you need a network interface card
(NIC), a network cable (usually a CAT5 cable), and a network to connect
to. Different networks are configured to use different network speeds;
make sure your NIC is compatible with the network to which you want to
To add an Ethernet connection, follow these steps:
Click the Devices tab.
Click the New button on the
Select Ethernet connection from the
Device Type list, and click
If you have already added the network interface card to
the hardware list, select it from the Ethernet
card list. Otherwise, select Other Ethernet
Card to add the hardware device.
The installation program detects supported Ethernet devices and
prompts you to configure them. If you configured any Ethernet
devices during the installation, they are displayed in the
hardware list on the Hardware tab.
If you selected Other Ethernet Card, the
Select Ethernet Adapter window appears. Select
the manufacturer and model of the Ethernet card. Select the device
name. If this is the system's first Ethernet card, select
eth0 as the device name; if this is the second
Ethernet card, select eth1 (and so on). The
Network Administration Tool also allows
you to configure the resources for the NIC. Click
Forward to continue.
In the Configure Network Settings window as
shown in Figure 18-2, choose between
DHCP and a static IP address. If the device receives a different IP
address each time the network is started, do not specify a
hostname. Click Forward to continue.
Click Apply on the Create
Ethernet Device page.

After configuring the Ethernet device, it appears in the device list as
shown in Figure 18-3.

After adding the Ethernet device, you can edit its configuration by
selecting the device from the device list and clicking
Edit. For example, when the device is added, it
is configured to start at boot time by default. To change this setting,
select to edit the device, modify the Activate device when
computer starts value, and save the changes.
When the device is added, it is not activated immediately, as seen by
its Inactive status. To activate the device, select
it from the device list, and click the Activate
button. If the system is configured to activate the device when the
computer starts (the default), this step does not have to be performed
If you associate more than one device with an Ethernet card, the
subsequent devices are device aliases. A device
alias allows you to setup multiple virtual devices for one physical
device, thus giving the one physical device more than one IP
address. For example, you can configure an eth1 device and an eth1:1
device. For details, refer to Section 18.11 Device Aliases.
