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 8 and Fedora >=29 like systems, the requirements can be met by installing the following packages: NetworkManager-nmlib, libsemanage-python, policycoreutils-python.
- On CentOS 7 and Fedora <=28 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-dev.
- On older 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.
Requirements¶
The below requirements are needed on the host that executes this module.
- dbus
- NetworkManager-libnm (or NetworkManager-glib on older systems)
- nmcli
