The NetworkManager integrated in all graphical user
interfaces of siduction offers a quick configuration of network cards
(WLAN and Ethernet). In the terminal, the script nmcli
provides access to the functionality of the NetworkManager.
Wireless networks are scanned. You can connect to the networks found
and make settings for the encryption method, the IPv4 or IPv6 Internet
protocol and a proxy server. The backend is iwd. The
Ethernet configuration takes place automatically when using a DHCP
server on the router (dynamic assignment of an IP address), but there is
also the option of a manual setup (from netmasks to name servers).
On the live medium and after installation, the NetworkManager with its backend iwd is already configured and ready for use.
In the graphical user interface, the NetworkManager is located in the taskbar. It is largely self-explanatory.
With nmcli or
nmtui a powerful command line client is
available for the daily use of the NetworkManager. nmtui offers
a user-friendly ncurses interface within the terminal. Here too, the
function is largely self-explanatory. If the script is not available,
install it with :
apt install network-managerThe start command in the console is
nmcli.
More information at network -
nmcli.
If you have all the necessary information to hand, a single command
line is sufficient.
Example:
Device Name = wlan0
Device Type = wifi
SSID = HOME_WLAN
Passwodt = s3Hrg3he!m
Command to set up the WLAN connection:
nmcli device wifi connect "HOME_WLAN" password "s3Hrg3he!m"Disconnect with:
nmcli device down wlan0NetworkManager saves the connection data entered once. If you are
within range of this router again, NetworkManager automatically
re-establishes the connection. To change the behavior, please read the
man pages
man NetworkManager
and
man nm-settings
