> 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
connect.

selecting the device from the device list and clicking
<B

is configured to start at boot time by default. To change this setting,
select to edit the device, modify the <B

> When the device is added, it is not activated immediately, as seen by
its <B

>Inactive</B

it from the device list, and click the <B

button. If the system is configured to activate the device when the
computer starts (the default), this step does not have to be performed
again.
</P
><P
> If you associate more than one device with an Ethernet card, the
subsequent devices are <I
CLASS="FIRSTTERM"
>device aliases</I
>. 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 <A
