Chapter 3. Installing Red Hat Linux

The installation program will automatically detect any network devices you have and display them in

the Network Devices list.

Once you have selected a network device, click Edit. From the Edit Interface pop up screen, you

can choose to configure the IP address and Netmask of the device via DHCP (or manually if DHCP is

not selected) and you can choose to activate the device at boot time. If you select Activate on boot,

your network interface will be started when you boot. If you do not have DHCP client access or you

are unsure what to provide here, please contact your network administrator.

Figure 3 18. Editing a Network Device

Note

Do not use the numbers as seen in this sample configuration. These values will not work for your own

network configuration. If you are not sure what values to enter, contact your network administrator for

assistance.

If you have a hostname (fully qualified domain name) for the network device, you can choose to have

DHCP (Dynamic Host Configuration Protocol) automatically detect it or you can manually enter the

hostname in the field provided.

Finally, if you entered the IP and Netmask information manually, you may also enter the Gateway

address and the Primary, Secondary, and Tertiary DNS addresses.

Tip

Even if your computer is not part of a network, you can enter a hostname for your system. If you do

not take this opportunity to enter a name, your system will be known as localhost.

Tip

To change your network configuration after you have completed the installation, use the Network

Administration Tool.

Type the redhat config network command in a shell prompt to launch the Network Administra 

tion Tool. If you are not root, it will prompt you for the root password to continue.
