Introduction to NetworkManager

NetworkManager is a set of co-operative tools that make networking simple and straightforward. Whether 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.

This package is known to build and work properly using an LFS-7.10 platform.

Package Information

NetworkManager Dependencies


dbus-glib-0.106, libgudev-230, libndp-1.6, libnl-3.2.28, and NSS-3.26



BlueZ-5.41, GTK-Doc-1.25, Qt-5.7.0 (for examples), ModemManager-1.6.0, Valgrind-3.11.0, libteam, PPP, and RP-PPPoE

User Notes:

Installation of NetworkManager

If Qt-5.7.0 is installed and the Qt based examples are desired, fix the configure script:

sed -e '/Qt[CDN]/s/Qt/Qt5/g'       \
    -e 's/moc_location/host_bins/' \
    -i configure

Install NetworkManager by running the following commands:

CXXFLAGS="-O2 -fPIC"             \
./configure --prefix=/usr        \
            --sysconfdir=/etc    \
            --localstatedir=/var \
            --with-nmtui         \
            --disable-ppp        \
            --with-systemdsystemunitdir=no \
            --docdir=/usr/share/doc/network-manager-1.4.0 &&

An already active graphical session with bus address is necessary to run the tests. To test the results, issue: make check.

Now, as the root user:

make install

Command Explanations

CXXFLAGS="-O2 -fPIC": These compiler options are necessary to build the Qt5 based examples.

--with-nmtui: This parameter enables build of nmtui.

--with-systemdsystemunitdir=no: This parameter is used for sysv init systems. If you use systemd, replace "no" by the proper directory.

--disable-ppp: This parameter disables parameteral PPP support in NetworkManager.

--enable-gtk-doc: Use this switch if you have installed GTK-Doc-1.25 and wish to build the API manuals.

--without-iptables: Use this switch if you don't have Iptables installed.

Configuring NetworkManager

Config Files


Configuration Information

For NetworkManager to work, at least minimal configuration file must be present. Such file is not installed with make install. Issue following command as the root user to create minimal NetworkManager.conf file:

cat >> /etc/NetworkManager/NetworkManager.conf << "EOF"

You can add dns=none to suppress changes to /etc/resolv.conf. See man 5 NetworkManager.conf for any additional options.

Boot Script

To automatically start the NetworkManager daemon when the system is rebooted, install the /etc/rc.d/init.d/networkmanagerbootscript from the blfs-bootscripts-20160902 package.

make install-networkmanager
