5.1. The NetworkManager Daemon5.2. Interacting with NetworkManager 5.3. Configuring Connection Settings

NetworkManager is a dynamic network contro and configuration system that attem!ts to kee! network de"ices and connections u! and acti"e when they are a"aia#e. NetworkManager consists of a coredaemon$ a %N&M' Notification (rea a!!et that !ro"ides network status information$ and gra!hica

configuration toos that can create$ edit and remo"e connections and interfaces. NetworkManager can #eused to configure the foowing ty!es of connections) 'thernet$ wireess$ mo#ie #road#and *such asceuar 3%+$ and DSL and PPPoE *,oint-to-,oint o"er 'thernet+. In addition$ NetworkManager aows

for the configuration of network aiases$ static routes$ DNS information and ,N connections$ as we asmany connection-s!ecific !arameters. /inay$ NetworkManager !ro"ides a rich (,I "ia D-0us which

aows a!!ications to uery and contro network configuration and state.

,re"ious "ersions of /edora shi!!ed with the Network Administration oo!$ which was commonyknown as system-config-network after its command ine in"ocation. In /edora 1$

NetworkManager re!aces the former Network Administration oo! whie !ro"iding enhancedfunctionaity$ such as user-s!ecific and mo#ie #road#and configuration. It is aso !ossi#e to configure

the network in /edora 1 #y editing interface configuration fies refer to Cha!ter $ Network Interfacesfor more information.

NetworkManager may #e instaed #y defaut on /edora. To ensure that it is$ first run the foowingcommand as the root user)

~]# yum install NetworkManager

5.1. he NetworkManager Daemon

The NetworkManager daemon runs with root !ri"ieges and is usuay configured to start u! at #oot

time. 4ou can determine whether the NetworkManager daemon is running #y entering this command asroot)

~]# service NetworkManager statusNetworkManager (i! "$%& is running'''

The service command wi re!ort NetworkManager is stoe! if the NetworkManager

ser"ice is not running. To start it for the current session)

~]# service NetworkManager start

un the ckconfig command to ensure that NetworkManager starts u! e"ery time the system #oots)

~]# ckconfig NetworkManager on

5.". #ntera$ting with NetworkManager

7sers do not interact with the NetworkManager system ser"ice directy. Instead$ you can !erform

network configuration tasks "ia NetworkManager8s Notification (rea a!!et. The a!!et has muti!estates that ser"e as "isua indicators for the ty!e of connection you are currenty using. 9o"er the !ointer o"er the a!!et icon for tooti! information on the current connection state.

5.2.4. User and ystem Connections

NetworkManager connections are aways either user connections or system connections. De!ending onthe system-s!ecific !oicy that the administrator has configured$ users may need root !ri"ieges to create

and modify system connections. NetworkManager8s defaut !oicy ena#es users to create and modifyuser connections$ #ut reuires them to ha"e root !ri"ieges to add$ modify or deete system connections.7ser connections are so-caed #ecause they are s!ecific to the user who creates them. In contrast tosystem connections$ whose configurations are stored under the +etc+sysconfig+network-

scrits+ directory *mainy in ifcfg- interface configuration fies+$ user

connection settings are stored in the %Conf configuration data#ase and the %N&M' keyring$ and are ony

a"aia#e during ogin sessions for the user who created them. Thus$ ogging out of the deskto! sessioncauses user-s!ecific connections to #ecome una"aia#e.

ip+ #n$rease se$urit& *& making ,'N $onne$tions user-spe$ifi$

0ecause NetworkManager uses the %Conf and %N&M' keyring a!!ications to store user connection

settings$ and #ecause these settings are s!ecific to your deskto! session$ it is highy recommended toconfigure your !ersona ,N connections as user connections. If you do so$ other non-root users on thesystem cannot "iew or access these connections in any way.

System connections$ on the other hand$ #ecome a"aia#e at #oot time and can #e used #y other users onthe system without first ogging in to a deskto! session.

NetworkManager can uicky and con"enienty con"ert user to system connections and "ice "ersa.Con"erting a user connection to a system connection causes NetworkManager to create the ree"antinterface configuration fies under the +etc+sysconfig+network-scrits+ directory$ and to

deete the %Conf settings from the user8s session. Con"ersey$ con"erting a system to a user-s!ecificconnection causes NetworkManager to remo"e the system-wide configuration fies and create the

corres!onding %Conf>%N&M' keyring settings.

The A)ai!a*!e to a!! users check#o; contros whether connections are user-s!ecific or system-wide
