Edit connections

This section shows how to use the network-manager built-in editor to modify connections as well as provide a reference for changing some of the settings.

Using nmcli Console

Aside from offering the possibility to manage and modify the network connections using the command-line, network-manager offers a built-in, interactive console to achieve the same. In order to use it type:

nmcli connection edit

It will bring up an interactive console. In the first step you will be prompted to enter the connection type. The list of valid connection types will be displayed on the screen. Once you select one you will be taken to the nmcli console where you have the possibility to modify its parameters.

Alternatively, if you know the valid connection types, you could jump straight to the nmcli console by providing the type as a parameter:

nmcli connection edit type <type>

where must be a valid connection type such as ‘wifi’.

An attempt to edit the wifi connection type would look like:

$ nmcli c edit

Valid connection types: generic, 802-3-ethernet (ethernet), pppoe,
802-11-wireless (wifi), wimax, gsm, cdma, infiniband, adsl, bluetooth, vpn,
802-11-olpc-mesh (olpc-mesh), vlan, bond, team, bridge, bond-slave, team-slave,
bridge-slave, no-slave, tun, ip-tunnel, macvlan, vxlan
Enter connection type: wifi
