%general-entities; ]> NetworkManager NetworkManager is a set of co-operative tools that make networking simple and straightforward. Whether you use WiFi, wired, 3G, or Bluetooth, NetworkManager allows you to quickly move from one network to another: Once a network has been configured and joined once, it can be detected and re-joined automatically the next time it's available. &lfs121_checked; Make sure that you disable the systemd-networkd service or configure it not to manage the interfaces you want to manage with NetworkManager. Package Information Download (HTTP): Download (FTP): Download MD5 sum: &NetworkManager-md5sum; Download size: &NetworkManager-size; Estimated disk space required: &NetworkManager-buildsize; Estimated build time: &NetworkManager-time; NetworkManager Dependencies Required Recommended , , , , , (for nmtui), , (runtime), , , , , and (runtime, built with D-Bus support) Optional , (for the test suite), (can be used instead of ), , , , ( or with qtdoc) (for examples), , , dnsmasq, firewalld, libaudit, libteam, mobile-broadband-provider-info, PPP, and RP-PPPoE If you wish to run the tests, check that at least the following options are enabled in the kernel configuration. Those options have been determined to be necessary, but may not be sufficient. Recompile the kernel if necessary: NetworkManager (test) If is installed and the Qt based examples are desired, fix two meson.build files: sed -e 's/-qt4/-qt5/' \ -e 's/moc_location/host_bins/' \ -i examples/C/qt/meson.build && sed -e 's/Qt/&5/' \ -i meson.build Fix the python scripts so that they use Python 3: grep -rl '^#!.*python$' | xargs sed -i '1s/python/&3/' Install NetworkManager by running the following commands: mkdir build && cd build && CXXFLAGS+="-O2 -fPIC" \ meson setup .. \ --prefix=/usr \ --buildtype=release \ -Dlibaudit=no \ -Dnmtui=true \ -Dovs=false \ -Dppp=false \ -Dselinux=false \ -Dsession_tracking=elogind \ -Dmodem_manager=false \ -Dsystemdsystemunitdir=no \ -Dsystemd_journal=false \ -Dqt=false && ninja mkdir build && cd build && CXXFLAGS+="-O2 -fPIC" \ meson setup .. \ --prefix=/usr \ --buildtype=release \ -Dlibaudit=no \ -Dnmtui=true \ -Dovs=false \ -Dppp=false \ -Dselinux=false \ -Dqt=false \ -Dsession_tracking=systemd \ -Dmodem_manager=false && ninja An already active graphical session with a bus address is necessary to run the tests. To test the results, issue ninja test. A few tests may fail, depending on enabled kernel options. Now, as the root user: ninja install && mv -v /usr/share/doc/NetworkManager{,-&NetworkManager-version;} If you have not passed the -Ddocs=true option to meson, you can install the pregenerated manual pages with (as the &root; user): for file in $(echo ../man/*.[1578]); do section=${file##*.} && install -vdm 755 /usr/share/man/man$section install -vm 644 $file /usr/share/man/man$section/ done If you have not used -Ddocs=true, the pregenerated HTML documentation can also be installed with (as the &root; user): cp -Rv ../docs/{api,libnm} /usr/share/doc/NetworkManager-&NetworkManager-version; CXXFLAGS="-O2 -fPIC": These compiler options are necessary to build the Qt5 based examples. -Ddocs=true: Use this switch to enable building man pages and documentation if is installed. -Dnmtui=true: This switch enables building nmtui. -Dsystemdsystemunitdir=no and -Dsystemd_journal=false: systemd is not used for sysv init systems, so prevent installing units and using the systemd journal. -Dovs=false: This switch disable the Open vSwitch integration because it needs . Remove it if you have installed on your system. -Dmodem_manager=false: This switch is required if ModemManager is not installed. Omit this switch if you have built ModemManager and mobile-broadband-provider-info. -Dsession_tracking=elogind: This switch is used to set elogind as the default program for session tracking. -Dsession_tracking=systemd: This switch is used to set systemd-logind as the default program for session tracking. -Dppp=false: This switch disables PPP support in NetworkManager since the programs necessary for it are not installed. Remove this switch if you need PPP support and have PPP installed. -Dlibaudit=no and -Dselinux=false: This switch disables support for libaudit and SELinux since they are not used in BLFS. -Dqt=false: This switch disables the Qt examples. Omit if you have Qt available and wish to install the examples. -Dcrypto=gnutls: Use this switch if you have GnuTLS installed and want to use it for certificate and key operations in NetworkManager, instead of using NSS (the default). -Dcrypto=null: Use this switch if neither NSS nor GnuTLS is installed but you want to build NetworkManager anyway. This switch will make NetworkManager lack some features (for example 802.1X). -Dsuspend_resume=upower: Use this switch if you have installed and want to use it (instead of &logind;) for suspend and resume support. /etc/NetworkManager/NetworkManager.conf /etc/NetworkManager/NetworkManager.conf For NetworkManager to work, at least a minimal configuration file must be present. Such a file is not installed with make install. Issue the following command as the root user to create a minimal NetworkManager.conf file: cat >> /etc/NetworkManager/NetworkManager.conf << "EOF" [main] plugins=keyfile EOF This file should not be modified directly by users of the system. Instead, system specific changes should be made using configuration files in the /etc/NetworkManager/conf.d directory. To allow polkit to manage authorizations, add the following configuration file: cat > /etc/NetworkManager/conf.d/polkit.conf << "EOF" [main] auth-polkit=true EOF To use something other than the built-in dhcp client (recommended if using only nmcli), use the following configuration (valid values include either dhcpcd or internal): cat > /etc/NetworkManager/conf.d/dhcp.conf << "EOF" [main] dhcp=dhcpcd EOF To prevent NetworkManager from updating the /etc/resolv.conf file, add the following configuration file: cat > /etc/NetworkManager/conf.d/no-dns-update.conf << "EOF" [main] dns=none EOF For additional configuration options, see man 5 NetworkManager.conf. To allow regular users to configure network connections, you should add them to the netdev group, and create a polkit rule that grants access. Run the following commands as the root user: groupadd -fg 86 netdev && /usr/sbin/usermod -a -G netdev <username> cat > /usr/share/polkit-1/rules.d/org.freedesktop.NetworkManager.rules << "EOF" polkit.addRule(function(action, subject) { if (action.id.indexOf("org.freedesktop.NetworkManager.") == 0 && subject.isInGroup("netdev")) { return polkit.Result.YES; } }); EOF To automatically start the NetworkManager daemon when the system is rebooted, install the /etc/rc.d/init.d/networkmanagerbootscript from the package. To start the NetworkManager daemon at boot, enable the previously installed systemd unit by running the following command as the root user: If using Network Manager to manage an interface, any previous configuration for that interface should be removed, and the interface brought down prior to starting Network Manager. NetworkManager make install-networkmanager systemctl enable NetworkManager Starting in version 1.11.2 of NetworkManager, a systemd unit named NetworkManager-wait-online.service is enabled, which is used to prevent services that require network connectivity from starting until NetworkManager establishes a connection. To disable this behavior, run the following command as the root user: systemctl disable NetworkManager-wait-online Installed Programs Installed Libraries Installed Directories NetworkManager, nmcli, nm-online, nmtui, and, symlinked to nmtui: nmtui-connect, nmtui-edit, and nmtui-hostname libnm.so and several modules under /usr/lib/NetworkManager /etc/NetworkManager, /usr/include/libnm, /usr/lib/NetworkManager, /usr/share/doc/NetworkManager-&NetworkManager-version;, /usr/share/gtk-doc/html/{libnm,NetworkManager} (if the documentation is built), and /var/lib/NetworkManager Short Descriptions nmcli is a command-line tool for controlling NetworkManager and getting its status nmcli nm-online is an utility to determine whether you are online nm-online nmtui is an interactive ncurses-based user interface for nmcli nmtui nmtui-connect is an interactive ncurses-based user interface to activate/deactivate connections nmtui-connect nmtui-edit is an interactive ncurses-based user interface to edit connections nmtui-edit nmtui-hostname is an interactive ncurses-based user interface to edit the hostname nmtui-hostname NetworkManager is the network management daemon NetworkManager libnm.so contains functions used by NetworkManager libnm.so
