Fedora 10 uses NetworkManager by default. The primary settings for any network devices will be automatically selected at installation time. Since there is no screen for selecting networking options, most devices will default to using DHCP.

Using NetworkManager has greatly improved networking for many wireless and some less common devices (mobile broadband, GSM, etc.), it may still have problems with some configurations. NetworkManager development and integration into Fedora is still an ongoing effort.

NOTE: The following steps do NOT apply to all users. NetworkManager is highly recommended for Laptop users, especially using wireless with security.

Disabling NetworkManager and Enabling network Service

On machines with a fixed networking device and a fixed IP address (e.g. desktop, server, appliance), it might be more practical to disable NetworkManager and use the older network service. Additionally users requiring virtual device types (bridging, bonding, or VLANs) will also need to use the network service.

Note that the Fedora 10 installer disables the network service by default. To switch to using the network service:

First disable NetworkManager and prevent it from automatically loading:

-------------------------------------------------------------------------------------------------
[mirandam@charon ~]$ sudo /etc/init.d/NetworkManager stop
Stopping NetworkManager daemon: [ OK ]

[mirandam@charon ~]$ sudo /sbin/chkconfig --level 35 NetworkManager off
-------------------------------------------------------------------------------------------------

Next, configure your network settings:

-------------------------------------------------------------------------------------------------
[mirandam@charon ~]$ sudo system-config-network
-------------------------------------------------------------------------------------------------

You should have an eth0 device already showing. To configure the IP settings click on Edit. Do not forget to set DNS on the DNS tab (if you're using fixed IP's). Make sure the eth0 is selected as Active. Then File > Save and quit.

Next, enable the service and make sure it loads at next boot:

-------------------------------------------------------------------------------------------------
[mirandam@charon ~]$ sudo /etc/init.d/network start
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: [ OK ]

[mirandam@charon ~]$ sudo /sbin/chkconfig --level 35 network on
-------------------------------------------------------------------------------------------------

While it may be possible to re-activate your network without a reboot, it may be recommended to reboot.

Startup Applications Requiring Network

Some applications require the network to be initialized during boot. If you are using NetworkManager and having these problems, edit /etc/sysconfig/network as 'root' and add the following line:

NETWORKWAIT=1.

Or run:

-------------------------------------------------------------------------------------------------
[mirandam@charon ~]$ sudo su -c 'echo NETWORKWAIT=1 >> /etc/sysconfig/network'
-------------------------------------------------------------------------------------------------
