NetworkManager осигурява автоматично откриване на мрежи и конфигуриране на системата. Веднъж активирана, услугата NetworkManager също следи за мрежовите интерфейси и може автоматично да превключва на най-добрата връзка във всеки определен момент. Приложенията, включващи поддръжка на NetworkManager могат автоматично да превключват между режими онлайн и офлайн, когато системата се свърже или загуби връзка с мрежата.

Тези инструменти са най-полезни за модерните лаптопи, при които потребителят може да се мести в различни безжични мрежи и да се включва към множество жични мрежи, но NetworkManager предоставя също и характеристики, които са от значение за стационарните компютри. Настоящите версии на NetworkManager поддържат модемни връзки, и някои типове VPN. Разработването на тези характеристики продължава.

NetworkManager изисква Fedora да има драйвери за жичните и безжичните интерфейси на компютъра. Много производители на модеми и безжични устройства предоставят ограничена поддръжка за Linux. Може да е необходимо да инсталирате допълнителни драйвери или вграден софтуер на вашата система Fedora, за да активирате тези интерфейси.

Чрез команден ред
Процесът на инсталиране на Fedora автоматично включва NetworkManager. За да го активирате, въведете следните команди в прозореца на терминала:

1. Set the main service to automatically start on boot: 1. Start the service:

For each command, enter the root password at the prompt.

Graphical Way
Start the  program, enter your root password and activate the   service for runlevel 5.

Gnome-specific information
The NetworkManager tray icon automatically appears on your desktop once the services are started. If the NetworkManager service is active, then the tray icon appears each time that you log in to your desktop.

NetworkManager also stores any encryption keys in the gnome-keyring manager. If your are prompted to enter the keyring password after login, then keep reading. If your login password & the keyring password are the same, then there is a tool built to open the keyring for you on login. The package is called pam_keyring. To configure your system first install pam_keyring with yum: su -c 'yum -y install pam_keyring' Second you'll need to modify your /etc/pam.d/gdm file. su -c 'gedit /etc/pam.d/gdm' Add the following lines auth   optional    pam_keyring.so try_first_pass session optional   pam_keyring.so

The order in which this lines are placed in this file are important, here is a copy from a working system auth      required    pam_env.so auth       optional    pam_keyring.so try_first_pass <--- auth      include     system-auth account   required    pam_nologin.so account    include     system-auth password  include     system-auth session   optional    pam_keyinit.so force revoke session   include     system-auth session   required    pam_loginuid.so session    optional    pam_console.so session    optional    pam_keyring.so <---
 * 1) %PAM-1.0

Now reboot your computer. After login the keyring will be unlocked for you.

Changing keyring password

If your keyring password is different from your login password, you will be prompted to enter it every time you login to your computer. To 'fix' this, see below:

Fedora 10 or older

If you are running Fedora 10 or older, you should first install the following tools:

su -c 'yum -y install gnome-keyring-manager gnome-keyring pam_keyring'

Once you have installed pam_keyring and gnome-keyring, you will need to log out and back on. Then you can run /usr/libexec/pam-keyring-tool -c to change the default password. Alternatively you can now change a password through gnome-keyring-manager. Download and install gnome-keyring-manager. Then highlight the keyring and select Change Keyring Password from the Keyring menu of gnome-keyring-manager.

Fedora 11 and newer

The Seahorse Encryption Key Manager has replaced gnome-keyring-manager in Fedora 11 onwards. You can install Seahorse via Add/Remove Software or from the command line:

su -c 'yum -y install seahorse'

Once you have installed Seahorse, you will find its program icon titled 'Passwords and Encryption Keys' in the Applications...Accessories menu folder. To change the default keyring password, start Seahorse then right click Passwords:login at the top of the Passwords tab and select Change Password.

KDE specific information
To control NetworkManager by a system tray applet you need to install and start the program  of the same named package. The keys to the different networks are stored automatically in KDE's password storage system kwalletmanager.
