NetworkManager-1.30.2
Introduction to 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.
This package is known to build and work properly using an LFS-10.1
platform.

Kernel Configuration
If you wish to run the tests, enable the following options in the
kernel configuration and recompile the kernel if necessary:
Device Drivers --->
[*] Network device support [CONFIG_NETDEVICES] --->
[*] Bonding driver support [CONFIG_BONDING]
[*] Dummy net driver support [CONFIG_DUMMY]
[*] Ethernet team driver support [CONFIG_NET_TEAM]
Installation of NetworkManager
If Qt-5.15.2 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 a missing meson.build file for initrd hooks (not used in BLFS):
sed '/initrd/d' -i src/core/meson.build
Fix the python scripts so that they use Python 3:
grep -rl '^#!.*python$' | xargs sed -i '1s/python/&3/'
Fix a security vulnerability in the matching system:
sed -i 's/str, 0/str ?: "", 0/' src/core/nm-core-utils.c
Install NetworkManager by running
the following commands:
mkdir build &&
cd build &&
CXXFLAGS+="-O2 -fPIC" \
meson --prefix /usr \
-Dlibaudit=no \
-Dlibpsl=false \
-Dnmtui=true \
-Dovs=false \
-Dppp=false \
-Dselinux=false \
-Dudev_dir=/lib/udev \
-Dsession_tracking=elogind \
-Dmodem_manager=false \
-Dsystemdsystemunitdir=no \
-Dsystemd_journal=false \
-Dqt=false \
.. &&
ninja
An already active graphical session with a bus address is necessary
to run the tests. To test the results, as the root user, issue:
ninja test. Five
tests, devices/test-acd
, platform/test-tc-linux
, platform/test-route-linux
, platform/test-link-linux
, and platform/test-cleanup-linux
, are known to fail.
Now, as the root
user:
ninja install &&
mv -v /usr/share/doc/NetworkManager{,-1.30.2}
Command Explanations
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 GTK-Doc-1.33.2
is installed.
-Dnmtui=true
: This
parameter enables building nmtui.
-Dsystemdsystemunitdir=no
and -Dsystemd_journal=false
: systemd is
not used for sysv init systems.
-Dlibpsl=false
and
-Dovs=false
: These switches
disable building with the respective libraries. Remove if you have
the needed libraries installed.
-Dmodem_manager=false
: This
switch is requried if ModemManager
is not installed. Omit 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.
-Dppp=false
: This parameter
disables PPP support in
NetworkManager.
-Dlibaudit=no
and
-Dselinux=false
: libaudit
and SELinux are not used in BLFS.
-Dqt=false
: disables the
QT examples. Omit if you have
QT available and wish to install
the examples.
Configuring NetworkManager
Config Files
/etc/NetworkManager/NetworkManager.conf
Configuration Information
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 dhclient or internal):
cat > /etc/NetworkManager/conf.d/dhcp.conf << "EOF"
[main]
dhcp=
dhclient
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 configuation 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
Boot Script
To automatically start the NetworkManager daemon when the
system is rebooted, install the /etc/rc.d/init.d/networkmanager
bootscript from
the blfs-bootscripts-20210110 package.
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.
