Establishing An Ethernet Connection - Red Hat ENTERPRISE LINUX 4 System Administration Manual

This chapter discusses each of these steps for each type of network connection.

17.2. 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
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.
7. Click Apply on the Create Ethernet Device page.
