Establishing an Ethernet Connection
169
This chapter discusses each of these steps for each type of network connection.
15.2. Establishing an Ethernet Connection
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.
To add an Ethernet connection, follow these steps:
1. Click the
Devices
tab.
2. Click the
New
button on the toolbar.
3. Select
Ethernet connection
from the
Device Type
list, and click
Forward
.
4. 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.
Note
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.
5. 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.
6. In the
Configure Network Settings
window shown in
Figure 15.2, “Ethernet Settings”
, 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.
7. Do not specify a value for the
Set MTU to
or
Set MRU to
fields.
MTU
stands for Maximum
Transmission Unit and
MRU
for Maximum Receive Unit; the network configuration tool will choose
appropriate values for both of these parameters. Click
Forward
to continue.
8. Click
Apply
on the
Create Ethernet Device
page.
