Estou tentando seguir o tutorial Como criar um ponto de acesso duplo malvado (com captura WPA / WPA2) . Tudo funcionou, exceto que eu fico preso às 20:51 no comando:
dhcpd -cf /etc/dhcpd.conf -pf /var/run/dhpcd.pid at0
Tudo está configurado exatamente como no vídeo do youtube. O arquivo /etc/dhcpd.conf parece exatamente o mesmo, como no vídeo - ** minuto 7:16 (não sei se deve ou não).
No vídeo não aparece, então eu não modifiquei o /etc/default/isc-dhcp-server . Eu tenho INTERFACES="" . Eu não sei qual interface devo colocar aqui para combinar com o tutorial.
Também não modifiquei este /etc/network/interfaces porque o vídeo não aparece. Este arquivo contém apenas:
auto lo
iface lo inet loopback
Eu não sei o que adicionar nele. Vou copiar o que eu digitei no terminal junto com o log:
