NAME
nmcli - command-line tool for controlling NetworkManager
SYNOPSIS
nmcli [OPTIONS...] {help | general | networking | radio | connection |
device | agent | monitor} [COMMAND] [ARGUMENTS...]
DESCRIPTION
nmcli is a command-line tool for controlling NetworkManager and
reporting network status. It can be utilized as a replacement for
nm-applet or other graphical clients. nmcli is used to create,
display, edit, delete, activate, and deactivate network connections, as
well as control and display network device status.
Typical uses include:
· Scripts: Utilize NetworkManager via nmcli instead of managing
network connections manually. nmcli 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 NetworkManager(8) for
details about these dispatcher scripts.
· Servers, headless machines, and terminals: nmcli can be used to
control NetworkManager without a GUI, including creating, editing,
starting and stopping network connections and viewing network
status.
OPTIONS
-t | --terse
Output is terse. This mode is designed and suitable for computer
(script) processing.
-p | --pretty
Output is pretty. This causes nmcli to produce easily readable
outputs for humans, i.e. values are aligned, headers are printed,
etc.
-m | --mode {tabular | multiline}
Switch between tabular and multiline output:
tabular
Output is a table where each line describes a single entry.
Columns define particular properties of the entry.
multiline
Each entry comprises multiple lines, each property on its own
line. The values are prefixed with the property name.
If omitted, default is tabular for most commands. For the commands
producing more structured information, that cannot be displayed on
a single line, default is multiline. Currently, they are:
· nmcli connection show ID
· nmcli device show
-c | --colors {yes | no | auto}
This option controls color output (using terminal escape
sequences). yes enables colors, no disables them, auto only
produces colors when standard output is directed to a terminal. The
default value is auto.
-f | --fields {field1,field2... | all | common}
This option is used to specify what fields (column names) should be
printed. Valid field names differ for specific commands. List
available fields by providing an invalid value to the --fields
option. all is used to print all valid field values of the
command. common is used to print common field values of the
command.
If omitted, default is common.
-g | --get-values {field1,field2... | all | common}
This option is used to print values from specific fields. It is
basically a shortcut for --mode tabular --terse --fields and is a
convenient way to retrieve values for particular fields. The values
are printed one per line without headers.
If a section is specified instead of a field, the section name will
be printed followed by colon separated values of the fields
belonging to that section, all on the same line.
-e | --escape {yes | no}
Whether to escape : and \ characters in terse tabular mode. The
escape character is \.
If omitted, default is yes.
-a | --ask
When using this option nmcli will stop and ask for any missing
required arguments, so do not use this option for non-interactive
purposes like scripts. This option controls, for example, whether
you will be prompted for a password if it is required for
connecting to a network.
-s | --show-secrets
When using this option nmcli will display passwords and secrets
that might be present in an output of an operation. This option
also influences echoing passwords typed by user as an input.
-w | --wait seconds
This option sets a timeout period for which nmcli will wait for
NetworkManager to finish operations. It is especially useful for
commands that may take a longer time to complete, e.g. connection
activation.
Specifying a value of 0 instructs nmcli not to wait but to exit
immediately with a status of success. The default value depends on
the executed command.
--complete-args
Instead of conducting the desired action, nmcli will list possible
completions for the last argument. This is useful to implement
argument completion in shell.
The exit status will indicate success or return a code 65 to
indicate the last argument is a file name.
NetworkManager ships with command completion support for GNU Bash.
-v | --version
Show nmcli version.
-h | --help
Print help information.
GENERAL COMMANDS
nmcli general {status | hostname | permissions | logging}
[ARGUMENTS...]
Use this command to show NetworkManager status and permissions. You can
also get and change system hostname, as well as NetworkManager logging
level and domains.
status
Show overall status of NetworkManager. This is the default action,
when no additional command is provided for nmcli general.
hostname [hostname]
Get and change system hostname. With no arguments, this prints
currently configured hostname. When you pass a hostname, it will be
handed over to NetworkManager to be set as a new system hostname.
Note that the term "system" hostname may also be referred to as
"persistent" or "static" by other programs or tools. The hostname
is stored in /etc/hostname file in most distributions. For example,
systemd-hostnamed service uses the term "static" hostname and it
only reads the /etc/hostname file when it starts.
permissions
Show the permissions a caller has for various authenticated
operations that NetworkManager provides, like enable and disable
networking, changing Wi-Fi and WWAN state, modifying connections,
etc.
logging [level level] [domains domains...]
Get and change NetworkManager logging level and domains. Without
any argument current logging level and domains are shown. In order
to change logging state, provide level and, or, domain parameters.
See NetworkManager.conf(5) for available level and domain values.
NETWORKING CONTROL COMMANDS
nmcli networking {on | off | connectivity} [ARGUMENTS...]
Query NetworkManager networking status, enable and disable networking.
on, off
Enable or disable networking control by NetworkManager. All
interfaces managed by NetworkManager are deactivated when
networking is disabled.
connectivity [check]
Get network connectivity state. The optional check argument tells
NetworkManager to re-check the connectivity, else the most recent
known connectivity state is displayed without re-checking.
Possible states are:
none
the host is not connected to any network.
portal
the host is behind a captive portal and cannot reach the full
Internet.
limited
the host is connected to a network, but it has no access to the
Internet.
full
the host is connected to a network and has full access to the
Internet.
unknown
the connectivity status cannot be found out.
RADIO TRANSMISSION CONTROL COMMANDS
nmcli radio {all | wifi | wwan} [ARGUMENTS...]
Show radio switches status, or enable and disable the switches.
wifi [on | off]
Show or set status of Wi-Fi in NetworkManager. If no arguments are
supplied, Wi-Fi status is printed; on enables Wi-Fi; off disables
Wi-Fi.
wwan [on | off]
Show or set status of WWAN (mobile broadband) in NetworkManager. If
no arguments are supplied, mobile broadband status is printed; on
enables mobile broadband, off disables it.
all [on | off]
Show or set all previously mentioned radio switches at the same
time.
ACTIVITY MONITOR
nmcli monitor
Observe NetworkManager activity. Watches for changes in connectivity
state, devices or connection profiles.
See also nmcli connection monitor and nmcli device monitor to watch for
changes in certain devices or connections.
CONNECTION MANAGEMENT COMMANDS
nmcli connection {show | up | down | modify | add | edit | clone |
delete | monitor | reload | load | import | export}
[ARGUMENTS...]
NetworkManager stores all network configuration as "connections", which
are collections of data (Layer2 details, IP addressing, etc.) that
describe how to create or connect to a network. A connection is
"active" when a device uses that connection's configuration to create
or connect to a network. There may be multiple connections that apply
to a device, but only one of them can be active on that device at any
given time. The additional connections can be used to allow quick
switching between different networks and configurations.
Consider a machine which is usually connected to a DHCP-enabled
network, but sometimes connected to a testing network which uses static
IP addressing. Instead of manually reconfiguring eth0 each time the
network is changed, the settings can be saved as two connections which
both apply to eth0, one for DHCP (called default) and one with the
static addressing details (called testing). When connected to the
DHCP-enabled network the user would run nmcli con up default , and when
connected to the static network the user would run nmcli con up
testing.
show [--active] [--order [+-]category:...]
List in-memory and on-disk connection profiles, some of which may
also be active if a device is using that connection profile.
Without a parameter, all profiles are listed. When --active option
is specified, only the active profiles are shown.
The --order option can be used to get custom ordering of
connections. The connections can be ordered by active status
(active), name (name), type (type) or D-Bus path (path). If
connections are equal according to a sort order category, an
additional category can be specified. The default sorting order is
equivalent to --order active:name:path. + or no prefix means
sorting in ascending order (alphabetically or in numbers), - means
reverse (descending) order. The category names can be abbreviated
(e.g. --order -a:na).
show [--active] [id | uuid | path | apath] ID...
Show details for specified connections. By default, both static
configuration and active connection data are displayed. When
--active option is specified, only the active profiles are taken
into account. Use global --show-secrets option to display secrets
associated with the profile.
id, uuid, path and apath keywords can be used if ID is ambiguous.
Optional ID-specifying keywords are:
id
the ID denotes a connection name.
uuid
the ID denotes a connection UUID.
path
the ID denotes a D-Bus static connection path in the format of
/org/freedesktop/NetworkManager/Settings/num or just num.
apath
the ID denotes a D-Bus active connection path in the format of
/org/freedesktop/NetworkManager/ActiveConnection/num or just
num.
It is possible to filter the output using the global --fields
option. Use the following values:
profile
only shows static profile configuration.
active
only shows active connection data (when the profile is active).
You can also specify particular fields. For static configuration,
use setting and property names as described in nm-settings(5)
manual page. For active data use GENERAL, IP4, DHCP4, IP6, DHCP6,
VPN.
When no command is given to the nmcli connection, the default
action is nmcli connection show.
up [id | uuid | path] ID [ifname ifname] [ap BSSID] [passwd-file file]
Activate a connection. The connection is identified by its name,
UUID or D-Bus path. If ID is ambiguous, a keyword id, uuid or path
can be used. When requiring a particular device to activate the
connection on, the ifname option with interface name should be
given. If the ID is not given an ifname is required, and
NetworkManager will activate the best available connection for the
given ifname. In case of a VPN connection, the ifname option
specifies the device of the base connection. The ap option specify
what particular AP should be used in case of a Wi-Fi connection.
If --wait option is not specified, the default timeout will be 90
seconds.
See connection show above for the description of the ID-specifying
keywords.
Available options are:
ifname
interface that will be used for activation.
ap
BSSID of the AP which the command should connect to (for Wi-Fi
connections).
passwd-file
some networks may require credentials during activation. You
can give these credentials using this option. Each line of the
file should contain one password in the form:
setting_name.property_name:the password
For example, for WPA Wi-Fi with PSK, the line would be
802-11-wireless-security.psk:secret12345
For 802.1X password, the line would be
802-1x.password:my 1X password
nmcli also accepts wifi-sec and wifi strings instead of
802-11-wireless-security. When NetworkManager requires a
password and it is not given, nmcli will ask for it when run
with --ask. If --ask was not passed, NetworkManager can ask
another secret agent that may be running (typically a GUI
secret agent, such as nm-applet or gnome-shell).
down [id | uuid | path | apath] ID...
Deactivate a connection from a device without preventing the device
from further auto-activation. Multiple connections can be passed to
the command.
Be aware that this command deactivates the specified active
connection, but the device on which the connection was active, is
still ready to connect and will perform auto-activation by looking
for a suitable connection that has the 'autoconnect' flag set. This
includes the just deactivated connection. So if the connection is
set to auto-connect, it will be automatically started on the
disconnected device again.
In most cases you may want to use device disconnect command
instead.
The connection is identified by its name, UUID or D-Bus path. If ID
is ambiguous, a keyword id, uuid, path or apath can be used.
See connection show above for the description of the ID-specifying
keywords.
If --wait option is not specified, the default timeout will be 10
seconds.
modify [--temporary] [id | uuid | path] ID
{option value | [+|-]setting.property value}...
Add, modify or remove properties in the connection profile.
To set the property just specify the property name followed by the
value. An empty value ("") removes the property value.
In addition to the properties, you can also use short names for
some of the properties. Consult the PROPERTY ALIASES section for
details.
If you want to append an item to the existing value, use + prefix
for the property name. If you want to remove just one item from
container-type property, use - prefix for the property name and
specify a value or an zero-based index of the item to remove (or
option name for properties with named options) as value. The + and
- modifies only have a real effect for multi-value (container)
properties like ipv4.dns, ipv4.addresses, bond.options, etc.
See nm-settings(5) for complete reference of setting and property
names, their descriptions and default values. The setting and
property can be abbreviated provided they are unique.
The connection is identified by its name, UUID or D-Bus path. If ID
is ambiguous, a keyword id, uuid or path can be used.
add [save {yes | no}] {option value | [+|-]setting.property value}...
Create a new connection using specified properties.
You need to describe the newly created connections with the
property and value pairs. See nm-settings(5) for the complete
reference. You can also use the aliases described in PROPERTY
ALIASES section. The syntax is the same as of the nmcli connection
modify command.
To construct a meaningful connection you at the very least need to
set the connection.type property (or use the type alias) to one of
known NetworkManager connection types:
· ethernet
· wifi
· wimax
· pppoe
· gsm
· cdma
· infiniband
· bluetooth
· vlan
· bond
· bond-slave
· team
· team-slave
· bridge
· bridge-slave
· vpn
· olpc-mesh
· adsl
· tun
· ip-tunnel
· macvlan
· vxlan
· dummy
The most typical uses are described in the EXAMPLES section.
Aside from the properties and values two special options are
accepted:
save
Controls whether the connection should be persistent, i.e.
NetworkManager should store it on disk (default: yes).
--
If a single -- argument is encountered it is ignored. This is
for compatibility with older versions on nmcli.
edit {[id | uuid | path] ID | [type type] [con-name name] }
Edit an existing connection or add a new one, using an interactive
editor.
The existing connection is identified by its name, UUID or D-Bus
path. If ID is ambiguous, a keyword id, uuid, or path can be used.
See connection show above for the description of the ID-specifying
keywords. Not providing an ID means that a new connection will be
added.
The interactive editor will guide you through the connection
editing and allow you to change connection parameters according to
your needs by means of a simple menu-driven interface. The editor
indicates what settings and properties can be modified and provides
in-line help.
Available options:
type
type of the new connection; valid types are the same as for
connection add command.
con-name
name for the new connection. It can be changed later in the
editor.
See also nm-settings(5) for all NetworkManager settings and
property names, and their descriptions; and nmcli-examples(7) for
sample editor sessions.
clone [--temporary] [id | uuid | path] ID new_name
Clone a connection. The connection to be cloned is identified by
its name, UUID or D-Bus path. If ID is ambiguous, a keyword id,
uuid or path can be used. See connection show above for the
description of the ID-specifying keywords. new_name is the name of
the new cloned connection. The new connection will be the exact
copy except the connection.id (new_name) and connection.uuid
(generated) properties.
The new connection profile will be saved as persistent unless
--temporary option is specified, in which case the new profile
won't exist after NetworkManager restart.
delete [id | uuid | path] ID...
Delete a configured connection. The connection to be deleted is
identified by its name, UUID or D-Bus path. If ID is ambiguous, a
keyword id, uuid or path can be used. See connection show above for
the description of the ID-specifying keywords.
If --wait option is not specified, the default timeout will be 10
seconds.
monitor [id | uuid | path] ID...
Monitor connection profile activity. This command prints a line
whenever the specified connection changes. The connection to be
monitored is identified by its name, UUID or D-Bus path. If ID is
ambiguous, a keyword id, uuid or path can be used. See connection
show above for the description of the ID-specifying keywords.
Monitors all connection profiles in case none is specified. The
command terminates when all monitored connections disappear. If you
want to monitor connection creation consider using the global
monitor with nmcli monitor command.
reload
Reload all connection files from disk. NetworkManager does not
monitor changes to connection files by default. So you need to use
this command in order to tell NetworkManager to re-read the
connection profiles from disk when a change was made to them.
However, the auto-loading feature can be enabled and then
NetworkManager will reload connection files any time they change
(monitor-connection-files=true in NetworkManager.conf(5)).
load filename...
Load/reload one or more connection files from disk. Use this after
manually editing a connection file to ensure that NetworkManager is
aware of its latest state.
import [--temporary] type type file file
Import an external/foreign configuration as a NetworkManager
connection profile. The type of the input file is specified by type
option.
Only VPN configurations are supported at the moment. The
configuration is imported by NetworkManager VPN plugins. type
values are the same as for vpn-type option in nmcli connection add.
VPN configurations are imported by VPN plugins. Therefore the
proper VPN plugin has to be installed so that nmcli could import
the data.
The imported connection profile will be saved as persistent unless
--temporary option is specified, in which case the new profile
won't exist after NetworkManager restart.
export [id | uuid | path] ID [file]
Export a connection.
Only VPN connections are supported at the moment. A proper VPN
plugin has to be installed so that nmcli could export a connection.
If no file is provided, the VPN configuration data will be printed
to standard output.
DEVICE MANAGEMENT COMMANDS
nmcli device {status | show | set | connect | reapply | modify |
disconnect | delete | monitor | wifi | lldp}
[ARGUMENTS...]
Show and manage network interfaces.
status
Print status of devices.
This is the default action if no command is specified to nmcli
device.
show [ifname]
Show detailed information about devices. Without an argument, all
devices are examined. To get information for a specific device, the
interface name has to be provided.
set [ifname] ifname [autoconnect {yes | no}] [managed {yes | no}]
Set device properties.
connect ifname
Connect the device. NetworkManager will try to find a suitable
connection that will be activated. It will also consider
connections that are not set to auto connect.
If --wait option is not specified, the default timeout will be 90
seconds.
reapply ifname
Attempt to update device with changes to the currently active
connection made since it was last applied.
modify ifname {option value | [+|-]setting.property value}...
Modify the settings currently active on the device.
This command lets you do temporary changes to a configuration
active on a particular device. The changes are not preserved in the
connection profile.
See nm-settings(5) for the list of available properties. Please
note that some properties can't be changed on an already connected
device.
You can also use the aliases described in PROPERTY ALIASES section.
The syntax is the same as of the nmcli connection modify command.
disconnect ifname...
Disconnect a device and prevent the device from automatically
activating further connections without user/manual intervention.
Note that disconnecting software devices may mean that the devices
will disappear.
If --wait option is not specified, the default timeout will be 10
seconds.
delete ifname...
Delete a device. The command removes the interface from the system.
Note that this only works for software devices like bonds, bridges,
teams, etc. Hardware devices (like Ethernet) cannot be deleted by
the command.
If --wait option is not specified, the default timeout will be 10
seconds.
monitor [ifname...]
Monitor device activity. This command prints a line whenever the
specified devices change state.
Monitors all devices in case no interface is specified. The monitor
terminates when all specified devices disappear. If you want to
monitor device addition consider using the global monitor with
nmcli monitor command.
wifi [list [ifname ifname] [bssid BSSID]]
List available Wi-Fi access points. The ifname and bssid options
can be used to list APs for a particular interface or with a
specific BSSID, respectively.
wifi connect (B)SSID [password password] [wep-key-type {key | phrase}]
[ifname ifname] [bssid BSSID] [name name] [private {yes | no}]
[hidden {yes | no}]
Connect to a Wi-Fi network specified by SSID or BSSID. The command
creates a new connection and then activates it on a device. This is
a command-line counterpart of clicking an SSID in a GUI client. The
command always creates a new connection and thus it is mainly
useful for connecting to new Wi-Fi networks. If a connection for
the network already exists, it is better to bring up (activate) the
existing connection as follows: nmcli con up id name. Note that
only open, WEP and WPA-PSK networks are supported at the moment. It
is also supposed that IP configuration is obtained via DHCP.
If --wait option is not specified, the default timeout will be 90
seconds.
Available options are:
password
password for secured networks (WEP or WPA).
wep-key-type
type of WEP secret, either key for ASCII/HEX key or phrase for
passphrase.
ifname
interface that will be used for activation.
bssid
if specified, the created connection will be restricted just
for the BSSID.
name
if specified, the connection will use the name (else NM creates
a name itself).
private
if set to yes, the connection will only be visible to the user
who created it. Otherwise the connection is system-wide, which
is the default.
hidden
set to yes when connecting for the first time to an AP not
broadcasting its SSID. Otherwise the SSID would not be found
and the connection attempt would fail.
wifi hotspot [ifname ifname] [con-name name] [ssid SSID]
[band {a | bg}] [channel channel] [password password]
Create a Wi-Fi hotspot. The command creates a hotspot connection
profile according to Wi-Fi device capabilities and activates it on
the device. The hotspot is secured with WPA if device/driver
supports that, otherwise WEP is used. Use connection down or device
disconnect to stop the hotspot.
Parameters of the hotspot can be influenced by the optional
parameters:
ifname
what Wi-Fi device is used.
con-name
name of the created hotspot connection profile.
ssid
SSID of the hotspot.
band
Wi-Fi band to use.
channel
Wi-Fi channel to use.
password
password to use for the created hotspot. If not provided, nmcli
will generate a password. The password is either WPA pre-shared
key or WEP key.
Note that --show-secrets global option can be used to print the
hotspot password. It is useful especially when the password was
generated.
wifi rescan [ifname ifname] [ssid SSID...]
Request that NetworkManager immediately re-scan for available
access points. NetworkManager scans Wi-Fi networks periodically,
but in some cases it can be useful to start scanning manually (e.g.
after resuming the computer). By using ssid, it is possible to scan
for a specific SSID, which is useful for APs with hidden SSIDs. You
can provide multiple ssid parameters in order to scan more SSIDs.
This command does not show the APs, use nmcli device wifi list for
that.
lldp [list [ifname ifname]]
Display information about neighboring devices learned through the
Link Layer Discovery Protocol (LLDP). The ifname option can be used
to list neighbors only for a given interface. The protocol must be
enabled in the connection settings.
SECRET AGENT
nmcli agent {secret | polkit | all}
Run nmcli as a NetworkManager secret agent, or polkit agent.
secret
Register nmcli as a NetworkManager secret agent and listen for
secret requests. You do usually not need this command, because
nmcli can handle secrets when connecting to networks. However, you
may find the command useful when you use another tool for
activating connections and you do not have a secret agent available
(like nm-applet).
polkit
Register nmcli as a polkit agent for the user session and listen
for authorization requests. You do not usually need this command,
because nmcli can handle polkit actions related to NetworkManager
operations (when run with --ask). However, you may find the command
useful when you want to run a simple text based polkit agent and
you do not have an agent of a desktop environment. Note that
running this command makes nmcli handle all polkit requests, not
only NetworkManager related ones, because only one polkit agent can
run for the session.
all
Runs nmcli as both NetworkManager secret and a polkit agent.
PROPERTY ALIASES
Apart from the property-value pairs, connection add, connection modify
and device modify also accept short forms of some properties. They
exist for convenience. Some aliases can affect multiple connection
properties at once.
The overview of the aliases is below. An actual connection type is used
to disambiguate these options from the options of the same name that
are valid for multiple connection types (such as mtu).

ENVIRONMENT VARIABLES
nmcli's behavior is affected by the following environment variables.
LC_ALL
If set to a non-empty string value, it overrides the values of all
the other internationalization variables.
LC_MESSAGES
Determines the locale to be used for internationalized messages.
LANG
Provides a default value for the internationalization variables
that are unset or null.
INTERNATIONALIZATION NOTES
Be aware that nmcli is localized and that is why the output depends on
your environment. This is important to realize especially when you
parse the output.
Call nmcli as LC_ALL=C nmcli to be sure the locale is set to C while
executing in a script.
LC_ALL, LC_MESSAGES, LANG variables specify the LC_MESSAGES locale
category (in that order), which determines the language that nmcli uses
for messages. The C locale is used if none of these variables are set,
and this locale uses English messages.
EXIT STATUS
nmcli exits with status 0 if it succeeds, a value greater than 0 is
returned if an error occurs.
0
Success – indicates the operation succeeded.
1
Unknown or unspecified error.
2
Invalid user input, wrong nmcli invocation.
3
Timeout expired (see --wait option).
4
Connection activation failed.
5
Connection deactivation failed.
6
Disconnecting device failed.
7
Connection deletion failed.
8
NetworkManager is not running.
10
Connection, device, or access point does not exist.
65
When used with --complete-args option, a file name is expected to
follow.
EXAMPLES
This section presents various examples of nmcli usage. If you want even
more, please refer to nmcli-examples(7) manual page.
nmcli -t -f RUNNING general
tells you whether NetworkManager is running or not.
nmcli -t -f STATE general
shows the overall status of NetworkManager.
nmcli radio wifi off
switches Wi-Fi off.
nmcli connection show
lists all connections NetworkManager has.
nmcli -p -m multiline -f all con show
shows all configured connections in multi-line mode.
nmcli connection show --active
lists all currently active connections.
nmcli -f name,autoconnect c s
shows all connection profile names and their auto-connect property.
nmcli -p connection show "My default em1"
shows details for "My default em1" connection profile.
nmcli --show-secrets connection show "My Home WiFi"
shows details for "My Home WiFi" connection profile with all
passwords. Without --show-secrets option, secrets would not be
displayed.
nmcli -f active connection show "My default em1"
shows details for "My default em1" active connection, like IP, DHCP
information, etc.
nmcli -f profile con s "My wired connection"
shows static configuration details of the connection profile with
"My wired connection" name.
nmcli -p con up "My wired connection" ifname eth0
activates the connection profile with name "My wired connection" on
interface eth0. The -p option makes nmcli show progress of the
activation.
nmcli con up 6b028a27-6dc9-4411-9886-e9ad1dd43761 ap 00:3A:98:7C:42:D3
connects the Wi-Fi connection with UUID
6b028a27-6dc9-4411-9886-e9ad1dd43761 to the AP with BSSID
00:3A:98:7C:42:D3.
nmcli device status
shows the status for all devices.
nmcli dev disconnect em2
disconnects a connection on interface em2 and marks the device as
unavailable for auto-connecting. As a result, no connection will
automatically be activated on the device until the device's
'autoconnect' is set to TRUE or the user manually activates a
connection.
nmcli -f GENERAL,WIFI-PROPERTIES dev show wlan0
shows details for wlan0 interface; only GENERAL and WIFI-PROPERTIES
sections will be shown.
nmcli -f CONNECTIONS device show wlp3s0
shows all available connection profiles for your Wi-Fi interface
wlp3s0.
nmcli dev wifi
lists available Wi-Fi access points known to NetworkManager.
nmcli dev wifi con "Cafe Hotspot 1" password caffeine name "My cafe"
creates a new connection named "My cafe" and then connects it to
"Cafe Hotspot 1" SSID using password "caffeine". This is mainly
useful when connecting to "Cafe Hotspot 1" for the first time. Next
time, it is better to use nmcli con up id "My cafe" so that the
existing connection profile can be used and no additional is
created.
nmcli -s dev wifi hotspot con-name QuickHotspot
creates a hotspot profile and connects it. Prints the hotspot
password the user should use to connect to the hotspot from other
devices.
nmcli dev modify em1 ipv4.method shared
starts IPv4 connection sharing using em1 device. The sharing will
be active until the device is disconnected.
nmcli dev modify em1 ipv6.address 2001:db8::a:bad:c0de
temporarily adds an IP address to a device. The address will be
removed when the same connection is activated again.
nmcli connection add type ethernet autoconnect no ifname eth0
non-interactively adds an Ethernet connection tied to eth0
interface with automatic IP configuration (DHCP), and disables the
connection's autoconnect flag.
nmcli c a ifname Maxipes-fik type vlan dev eth0 id 55
non-interactively adds a VLAN connection with ID 55. The connection
will use eth0 and the VLAN interface will be named Maxipes-fik.
nmcli c a ifname eth0 type ethernet ipv4.method disabled ipv6.method
link-local
non-interactively adds a connection that will use eth0 Ethernet
interface and only have an IPv6 link-local address configured.
nmcli connection edit ethernet-em1-2
edits existing "ethernet-em1-2" connection in the interactive
editor.
nmcli connection edit type ethernet con-name "yet another Ethernet
connection"
adds a new Ethernet connection in the interactive editor.
nmcli con mod ethernet-2 connection.autoconnect no
modifies 'autoconnect' property in the 'connection' setting of
'ethernet-2' connection.
nmcli con mod "Home Wi-Fi" wifi.mtu 1350
modifies 'mtu' property in the 'wifi' setting of 'Home Wi-Fi'
connection.
nmcli con mod em1-1 ipv4.method manual ipv4.addr "192.168.1.23/24
192.168.1.1, 10.10.1.5/8, 10.0.0.11"
sets manual addressing and the addresses in em1-1 profile.
nmcli con modify ABC +ipv4.dns 8.8.8.8
appends a Google public DNS server to DNS servers in ABC profile.
nmcli con modify ABC -ipv4.addresses "192.168.100.25/24 192.168.1.1"
removes the specified IP address from (static) profile ABC.
nmcli con import type openvpn file ~/Downloads/frootvpn.ovpn
imports an OpenVPN configuration to NetworkManager.
nmcli con export corp-vpnc /home/joe/corpvpn.conf
exports NetworkManager VPN profile corp-vpnc as standard Cisco
(vpnc) configuration.
NOTES
nmcli accepts abbreviations, as long as they are a unique prefix in the
set of possible options. As new options get added, these abbreviations
are not guaranteed to stay unique. For scripting and long term
compatibility it is therefore strongly advised to spell out the full
option names.
BUGS
There are probably some bugs. If you find a bug, please report it to
