This adds a global "--offline" option and allows its use with "add" and
"modify" commands. The "add" looks like this:
$ nmcli --offline conn add type ethernet ens3 ipv4.dns 192.168.1.1 \
>output.nmconnection
The "modify" is essentially implementing what's been suggested by
Beniamino in bugzilla ticked (referred to below):
$ nmcli --offline connection modify ens3 ipv4.dns 192.168.1.1 \
<input.nmconnection >output.nmconnection
Other commands don't support the argument at the moment:
$ nmcli --offline c up ens3
Error: 'up' command doesn't support --offline mode.

<para>
|

This command activates a VPN connection profile enabling nmcli to interact with the user
|
|
('--ask'): this will allow nmcli to prompt for the VPN password on the command line when
|
|
the <emphasis>password-flags</emphasis> are set to '0x02' ('always ask', see

<link linkend='nm-settings'><citerefentry><refentrytitle>nm-settings</refentrytitle><manvolnum>5</manvolnum></citerefentry></link>

This is particularly useful for OTP based VPNs, as the user needs to be prompted for the
|
|
password each time the connection is activated.

<para>
|
|
This example demonstrates adding a bond master connection and two slaves. The
|
|
first command adds a master bond connection, naming the bonding interface
|
|
<emphasis>mybond0</emphasis> and using <emphasis>active-backup</emphasis> mode.
|
|
The next two commands add slaves connections, both enslaved to <emphasis>mybond0</emphasis>.
|
|
The first slave will be bound to <emphasis>eth1</emphasis> interface, the second to
|
|
<emphasis>eth2</emphasis>.

|
|
<para>
|
|
This example demonstrates adding a team master connection profile and two slaves. It is
|
|
very similar to the bonding example. The first command adds a master team profile, naming
|
|
the team interface and the profile <emphasis>Team1</emphasis>. The team configuration
|
|
for the master is read from <emphasis>team1-master-json.conf</emphasis> file. Later, you can
|
|
change the configuration with <emphasis>modify</emphasis> command
|
|
(<emphasis role="bold">nmcli con modify Team1 team.config team1-master-another-json.conf</emphasis>).
|
|
The last two commands add slaves profiles, both enslaved to <emphasis>Team1</emphasis>.
|
|
The first slave will be bound to the <emphasis>em1</emphasis> interface, the second to
|
|
<emphasis>em2</emphasis>. The slaves don't specify <emphasis>config</emphasis> and thus
|
|
<emphasis>teamd</emphasis> will use its default configuration. You will activate the whole setup
|
|
by activating both slaves:
|
|
<screen> <prompt>$ </prompt><userinput>nmcli con up Team1-slave1</userinput>
|
|
<prompt>$ </prompt><userinput>nmcli con up Team1-slave2</userinput></screen>
|
|
By default, the created profiles are marked for auto-activation. But if another
|
|
connection has been activated on the device, the new profile won't activate
|
|
automatically and you need to activate it manually.

|
|
<prompt>$ </prompt><userinput>nmcli con modify TowerBridge bridge.stp no</userinput></screen>
|
|
<para>
|
|
This example demonstrates adding a bridge master connection and two slaves. The
|
|
first command adds a master bridge connection, naming the bridge interface and
|
|
the profile as <emphasis>TowerBridge</emphasis>.
|
|
The next two commands add slaves profiles, both will be enslaved to
|
|
<emphasis>TowerBridge</emphasis>.
|
|
The first slave will be tied to <emphasis>ens3</emphasis> interface, the second to
|
|
<emphasis>ens4</emphasis>.
|
|
The last command will disable 802.1D STP for the TowerBridge profile.

|
|
<prompt>$ </prompt><userinput>nmcli -p con show my-con-em1</userinput></screen>
|
|
<para>
|
|
The first command adds an Ethernet connection profile named <emphasis>my-con-em1</emphasis>
|
|
that is bound to interface name <emphasis>em1</emphasis>. The profile is configured
|
|
with static IP addresses. Three addresses are added, two IPv4 addresses and one IPv6.
|
|
The first IP 192.168.100.100 has a prefix of 24 (netmask equivalent of 255.255.255.0).
|
|
Gateway entry will become the default route if this profile is activated on em1 interface
|
|
(and there is no connection with higher priority). The next two addresses do not
|
|
specify a prefix, so a default prefix will be used, i.e. 32 for IPv4 and 128 for IPv6.
|
|
The second, third and fourth commands modify DNS parameters of the new connection profile.
|
|
The last <emphasis>con show</emphasis> command displays the profile so that all
|
|
parameters can be reviewed.

Wi-Fi will be turned back on.

Connection 'ethernet-4' (de89cdeb-a3e1-4d53-8fa0-c22546c775f4) successfully

|
|
<para>
|
|
Example session in the nmcli interactive connection editor.
|
|
The scenario creates an Ethernet connection profile with static addressing (IPs and DNS).
|
|
</para>
|
|
</example>
|
|
|
|
<example><title>Bluetooth connection profiles</title>
|
|
<para>NetworkManger supports both connecting to NAP and DUN devices as a client. It also
|
|
supports sharing the network via a NAP server.
|
|
</para>
|
|
<para>For NAP client connections, NetworkManager automatically creates a suitable in-memory profile
|
|
for paired devices if none is available. You may use that generated profile directly, but you may also modify
|
|
and persist it, which will prevent to automatically re-create it. You may also create a profile from scratch.
|
|
For example, the following uses DHCP and IPv6 autoconf for address configuration:
|
|
</para>
|
|
<screen><prompt>$ </prompt><userinput>nmcli connection add type bluetooth con-name "Profile for My Bluetooth Device (NAP)" autoconnect no bluetooth.type panu bluetooth.bdaddr "$BDADDR"</userinput></screen>
|
|
<para>For DUN connections, the user needs to configure modem settings and hence no profile
|
|
gets created automatically. The modem settings depend on your device and you either need
|
|
a "gsm" or a "csma" section. For example,
|
|
</para>
|
|
<screen><prompt>$ </prompt><userinput>nmcli connection add type bluetooth con-name "Profile for My Bluetooth Device (DUN)" autoconnect no bluetooth.type dun bluetooth.bdaddr "$BDADDR" gsm.apn apn.com</userinput></screen>
|
|
<para>Finally, you can create a bluetooth hotspot. BlueZ implements those as a bridge device,
|
|
so such profiles also have a bridge section. Also, you probably want to set IP methods as "shared",
|
|
so that clients get automatic IP addressing. Note that the "shared" IPv4 method requires dnsmasq to be available.
|
|
</para>
|
|
<screen><prompt>$ </prompt><userinput>nmcli connection add type bluetooth con-name "My Bluetooth Hotspot" autoconnect no ifname btnap0 bluetooth.type nap ipv4.method shared ipv6.method shared</userinput></screen>
|
|
</example>
|
|
|
|
<example><title>Offline use</title>
|
|
<screen><prompt>$ </prompt><userinput>nmcli --offline con add type ethernet '
|
|
conn.id eth0 \
|
|
conn.interface-name eth0 \
|
|
>/sysroot/etc/NetworkManager/system-connections/eth0.nmconnection</userinput></screen>
|
|
<para>
|
|
Creates a connection file in keyfile format without using the NetworkManager service.
|
|
This allows for use of familiar <command>nmcli</command> syntax in situations
|
|
where the service is not running, such as during system installation of image
|
|
provisioning and ensures the resulting file is correctly formatted.
|
|
</para>
|
|
<screen><prompt>$ </prompt><userinput>nmcli --offline con modify type ethernet '
|
|
conn.id eth0-ipv6 \
|
|
ipv4.method disabled \
|
|
</sysroot/etc/NetworkManager/system-connections/eth0.nmconnection \
|
|
>/sysroot/etc/NetworkManager/system-connections/eth0-ipv6.nmconnection</userinput></screen>
|
|
<para>
|
|
Read and write a connection file without using the NetworkManager service, modifying
|
|
some properties along the way.
|
|
</para>
|
|
<para>
|
|
This allows templating of the connection profiles using familiar
|
|
<command>nmcli</command> syntax in situations where the service is not running.
|
|
