To add a network device, start Red Hat Network
Administration Tool and click Add
in the Devices tab. From the Device
Type menu, you have the following options:
Ethernet — Select this option to configure a network interface
card (NIC).
Modem — Select this option to configure a modem for a dial-up
connection.
ISDN — Select this option if you subscribe to an ISDN Internet
service.
xDSL — Select this option if you subscribe to a type of xDSL service
such as ADSL.
CIPE — Select this option to configure a virtual CIPE device.
Wireless — Select this option to configure a wireless network
device.
Token Ring — Select this option to configure a token ring
device.
After selecting a device type, you will see a window with tabbed
panes. The tabs vary depending on which device type you selected. All
device types will have the following tabs:
General — Give the device a nickname,
choose to activate the device when the computer boots, and choose
to allow users to enable and disable the device.
Protocols — Edit the TCP/IP settings such
as an IP address (including DHCP), hostname, and static network routes.
If you selected Ethernet as the device type, you
will also see a Hardware Device tab. Use this tab
to configure a device alias. A device alias allows you to setup multiple
virtual devices for one physical device.
Click the Provider tab to enter the phone number,
login, and password for your dial-up account. Use the
Compression tab to enable different forms of
compression. The Options tab allows you to
configure PPP options, and the Advanced tab
provides pulldown menus to customize the hangup timeout value, the
dial mode, and the modem port. You can also configure the device to
restart if the connection dies using the Advanced tab.
The tabs for ISDN configuration are similar to the tabs for
Modem configuration, except there is an
additional tab that allows you to use callback and configure the
callback settings.
xDSL provides an Internet connection through an Ethernet card. To
configure xDSL, you must configure an Ethernet device first. Most xDSL
services require you to configure the Ethernet device to obtain an IP
address via DHCP. Consult your Internet provider for details. After
configuring the Ethernet device, add an xDSL device. From the
Provider tab, select the appropriate Ethernet
device to use to establish your connection.
CIPE stands for Crypto IP Encapsulation. It is used to configure an IP
tunneling device. For example, CIPE can be used to grant access from
the outside world into a Virtual Private Network (VPN). If you need to
setup a CIPE device, contact your system administrator for the correct
values.
The tabs for Wireless configuration are similar to the tabs for an
Ethernet device, except there is an extra tab called Wireless
Settings. This tab allows you to configure the network ID,
mode, frequency, channel, transmit rate, and key for the wireless
device.
The Token Ring device configuration is similar to
the Ethernet device configuration. There is an
additional Hardware Device tab.
