How can I connect to a 802.1x PEAP secured wired network without using any GUI on Debian? I want a non-GUI way as I am using a customized GUI. Also the network doesn't take any certificate for PEAP. How can I connect to such a network?
nmtui, if you are using network-manager. Nmtui is a terminal ui for the networkmanager. It lets you edit, (de-)activate and monitor available connections.
