3.0 Managing Network Connections Traditionally
In contrast to NetworkManager, traditional network configuration requires you
to configure network interfaces and switch between networks
when moving. The program ifup is used to activate preconfigured
network devices. It means that all network devices must be
configured before you can use them.
If you want to use traditional managing with ifup, disable NetworkManager first.
To disable NetworkManager during the
on the screen. To disable NetworkManager on an already
installed system, follow these steps:
On the first screen, set
NOTE: Switching to NetworkManager
NetworkManager can use the configuration from the directory
YaST uses this directory to store the network configuration. If you switch
from traditional configuration with YaST to NetworkManager, NetworkManager adopts
configurations from YaST.
After selecting traditional configuration, set up your network devices.
To configure your network devices, use YaST. Find the YaST modules
for all network devices in the
To allow users to control devices, set device
activation in YaST to .
A detailed description of the network configuration with YaST is
available in “Configuring a Network Connection with YaST” (Chapter “Basic Networking”, ↑Deployment Guide) and
“Wireless LAN” (Chapter “Wireless Communication”, ↑Deployment Guide).

module. Use this
module also for GPRS and CDMA modems.
To configure your internal or USB DSL modem, select the
If you have an external DSL modem with the ethernet connection, simply
connect the modem

- Configuring Wired Network Cards
YaST displays a general network configuration
dialog. To configure your network in the traditional way with the YaST,
The upper part of the traditional configuration shows a list with all the
network cards available for configuration. Any card properly detected is
listed with its name. Configure devices that could not be detected using
- Configuring Wireless Cards
To configure a wireless card, use the /usr/share/doc/packages/wireless-tools/README.firmware.
Some WLAN cards need a firmware image that must be loaded into the card
driver is initialized. This is the case with , , and
. Easily install the
firmware with the YaST Online Update. The firmware for Intel
PRO/Wireless cards ships with SUSE Linux and is automatically installed
by YaST as
soon as a card of this type is detected. More information about this subject
is available in the installed system in
Several techniques are used to control connectivity.
All require preconfigured network connections. Users have no right to add,
remove, or change them.
The most important are:
- ifplug or hotplug
ifplug and hotplug do not provide users with any possibility to control the
are activated with preconfigured settings automatically when a connection
becomes available. For a wired connection, this means the device is
when the cable is plugged in. For wireless connections, it depends on the
availability of the preconfigured WLAN network.
- System Configuration Profile Management (SCPM)
Network control is only the part of the SCPM capabilities. root
can grant rights to switch and configure SCPM to selected users.
- User-Controlled Devices
To grant users some rights to control connectivity,
set up your devices as user controlled. To do so, set the device
activation in YaST to
. With user-controlled devices, users
start, stop, and switch preconfigured connections.
