4.3. Installing via FTP

The FTP dialog applies only if you are installing from an FTP server (if you selected FTP in the

Installation Method dialog). This dialog allows you to identify the FTP server from which you

are installing Red Hat Enterprise Linux.

Figure 2.4. FTP Setup Dialog

Enter the name or IP address of the FTP site you are installing from, and the name of the

directory containing the

RedHat/

installation files for your architecture. For example, if the FTP

site contains the directory

/mirrors/redhat/arch/RedHat/

, enter

/mirrors/redhat/arch/

(where

arch

is replaced with the architecture type of your system, such as i386, ia64, ppc, or

s390). If everything was specified properly, a message box appears indicating that

base/hdlist

is being retrieved.

Next, the Welcome dialog appears.

Tip

You can save disk space by using the ISO images you have already copied to

the server. To accomplish this, install Red Hat Enterprise Linux using ISO

images without copying them into a single tree by loopback mounting them. For

each ISO image:

mkdir discX
