.SH DESCRIPTION
|
||||
.B nmcli
|
||||
is a command\(hyline tool for controlling NetworkManager and reporting on its status.
|
||||
It is not meant as a full replacement for \fInm\(hyapplet\fP or other similar clients
|
||||
but as a complementary utility to those programs.
|
||||
The main usage for \fInmcli\fP is on servers, headless machines or for power users
|
||||
who prefer the command line.
|
||||
is a command\(hyline tool for controlling NetworkManager and reporting network
|
||||
status. It can be utilized as a replacement for \fInm\(hyapplet\fP or other
|
||||
graphical clients. \fInmcli\fP is used to create, display, edit, delete, activate,
|
||||
and deactivate network connections, as well as control and display network device
|
||||
status.

Typical applications include:
|
||||
Typical uses include:
|
||||
.IP \(em 4
|
||||
Initscripts: ifup/ifdown can utilize NetworkManager via \fInmcli\fP instead of
|
||||
having to manage connections itself and possibly interfere with NetworkManager.
|
||||
Scripts: utilize NetworkManager via \fInmcli\fP instead of managing network
|
||||
connections manually. \fInmcli\fP supports a terse output format which is better
|
||||
suited for script processing. Note that Networkmanager can also execute scripts,
|
||||
called "dispatcher scripts", in response to network events. See
|
||||
\fBNetworkManager\fP for details about these dispatcher scripts.
|
||||
.IP \(em 4
|
||||
Servers, headless machines: No GUI is available; then \fInmcli\fP can be used
|
||||
to activate/deactivate connections. However, if a connection requires a secret
|
||||
in order to activate and if that secret is not stored at the system level,
|
||||
\fInmcli\fP will not be able to activate it; it is currently unable to supply
|
||||
the secrets to NetworkManager.
|
||||
.IP \(em 4
|
||||
User sessions: \fInmcli\fP can be used to activate/deactivate connections from
|
||||
the command line, but a client with a secret agent (like \fInm\(hyapplet\fP) is needed
|
||||
for supplying secrets not stored at the system level. Keyring dialogs and
|
||||
password prompts may appear if this happens.
|
||||
Servers, headless machines, and terminals: \fInmcli\fP can be used to control
|
||||
NetworkManager without a GUI, including creating, editing, starting and stopping
|
||||
network connections and viewing network status.
