It will ask us to define a connection type
|
|
|
|
|
|
|
|
|
|
----
|
|
|
|
|
Valid connection types: 802-3-ethernet (ethernet), 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
|
|
|
|
|
Enter connection type:
|
|
|
|
|
----
|
|
|
|
|
|
|
|
|
|
In this example we will use ethernet
|
|
|
|
|
|
|
|
|
|
----
|
|
|
|
|
Enter connection type: ethernet
|
|
|
|

----
|
|
|
|

|
|
|
|
Type 'describe [<setting>.<prop>]' for detailed property description.
|
|
|

|
|
|
You may edit the following settings: connection, 802-3-ethernet (ethernet), 802-1x, ipv4, ipv6
|
|
|
|
|
nmcli>
|
|
|
|
|
----
|
|
|
|
|
|
|

We will edit the setting "ipv4"

|
|
|
nmcli> goto ipv4
|
|
|
|
|
----
|
|
|
|
|
|
|
|
|
|
Note that after this our promt has changed to this to indicate that we

|
|
|
|
are currently editing the "ipv4" setting
|
|
|
|

|
|
|

----

|
|
|
nmcli ipv4>
|
|
|
|
|
----
|
|
|
|
|
|
|

|
|
List available properties under the setting "ipv4" and describe the
|
|
|
|
|
property "method"

|
|
nmcli ipv4> set method auto
|
|
|
|
|
----
|
|
|
|
|
|
|
|
|
|
Now that we have finished editing the "ipv4" setting let's go back to
|
|
|
|
|
the main level. Execute the following command until the prompt looks
|
|
|
|
|
like this "nmcli>"

If you need to list again the main settings use the "goto" command
|
|
|
|
|
without any arguments. After that just press enter and ignore the error.

=== Manually editing
|
|
|
|
|
|
|
|
|
|
To manually edit a ifcfg connection configuration open or create with a
|
|
|
|
|
text editor the configuration file of the connection located in
|
|
|
|
|
`/etc/sysconfig/network-scripts/ifcfg-`
|
|
|
|
|
|
|
|
|
|
A description of most common configuration options is available at:
|
|
|
|
|
http://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/s1-networkscripts-interfaces.html
|
|
|
|
|
|
|
|
|
|
To modify a connection password open with a text editor and edit the
|
|
|
|
|
file "keys-" located in "/etc/sysconfig/network-scripts/". The password
|
|
|
|
|
is stored in plain text. For example
|
|
|
|
|
|
|
|
|
|
----
|
|
|
|
|
$ cat /etc/sysconfig/network-scripts/keys-<connection name>
|
|
|
|
|
WPA_PSK='password'
|
|
|
|
|
----
|
|
|
|
|
|
|
|
|
|
Or if using keyfile, simply edit the connection file located inside
|
|
|
|
|
`/etc/NetworkManager/system-connections/`
|
|
|
|
|
|
|
|
|
|
Finally save the files and to apply changes to an already active
|
|
|
|
|
connection execute
|
|
|
|
|
|
|
|
|
|
----
|
|
|

|
The primary reference for nmcli are the manual pages nmcli and
|
|
|
|
|
nmcli-examples. For a quick reference, the user can type `nmcli
|
|
|
|
|
[help]` to print the supported options and commands. The help parameter
|
|
|
|
|
can also be used to obtain a more detailed description for the
|
|
|
|
|
individual commands. For example `nmcli connection help` and `nmcli
|
|
|
|
|
connection add help` show a description for the possible connection
|
|
|
|
|
operations and for how to add connections, respectively.
