NetworkManager-1.4.2

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

Required

dbus-glib-0.108, libgudev-230, libndp-1.6, libnl-3.2.28, and NSS-3.27.2

Recommended

Optional

BlueZ-5.43, GTK-Doc-1.25, Qt-5.7.0 (for examples), ModemManager-1.6.2, Valgrind-3.12.0, dnsmasq, libteam, PPP, and RP-PPPoE

User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/NetworkManager

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-1.4.2 &&
make

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

/etc/NetworkManager/NetworkManager.conf

Configuration Information

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

cat >> /etc/NetworkManager/NetworkManager.conf << "EOF"
[main]
plugins=keyfile
EOF

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

To allow regular users permission 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:

/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

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.

[Note]

Note

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.

make install-networkmanager
