¿Me gustaría saber cómo usar la línea de comandos para conectarme a una red cableada en general para Ubuntu 8.10?
En mi caso, conecto un cable a mi computadora portátil pero no funciona con mi WICD. Entonces me gusta probar el método de línea de comandos.
Aquí está el ifconfig de mis adaptadores de red:
