nmcli – Manage Networking

New in version 2.0.


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.
