nmcli – Manage Networking¶
Synopsis¶
Manage the network devices. Create, modify and manage various connection and device type e.g., ethernet, teams, bonds, vlans etc.
On CentOS and Fedora like systems, the requirements can be met by installing the following packages: NetworkManager-glib, libnm-qt-devel.x86_64, nm-connection-editor.x86_64, libsemanage-python, policycoreutils-python.
On Ubuntu and Debian like systems, the requirements can be met by installing the following packages: network-manager, python-dbus (or python3-dbus, depending on the Python version in use), libnm-glib-dev.
On openSUSE, the requirements can be met by installing the following packages: NetworkManager, python2-dbus-python (or python3-dbus-python), typelib-1_0-NMClient-1_0 and typelib-1_0-NetworkManager-1_0.
