> To communicate with other computers, computers need a network
connection. This is accomplished by having the operating system recognize
an interface card (such as Ethernet, ISDN modem, or token ring) and
configuring the interface to connect to the network.

> The <B
CLASS="APPLICATION"

used to configure the following types of network interfaces:

> To use the <B
CLASS="APPLICATION"
>Network Administration Tool</B
>, you must have root
privileges. To start the application, go to the <B

>Main Menu
Button</B
> (on the Panel) => <B
CLASS="GUIMENU"
>System Settings</B
> =>
<B
CLASS="GUIMENUITEM"
>Network</B
>, or type the command
<TT
CLASS="COMMAND"
>system-config-network</TT
> at a shell prompt (for example,
in an <B
CLASS="APPLICATION"
>XTerm</B
> or a <B
CLASS="APPLICATION"
>GNOME
terminal</B
>). If you type the command, the graphical version is
displayed if X is running, otherwise, the text-based version is
displayed. To force the text-based version to run, use the
<TT
CLASS="COMMAND"
>system-config-network-tui</TT
> command.
