ifconfig -a mostra a interface.
Você precisa usar -a para ver as interfaces que estão inativas. ifconfig sozinho mostra apenas as interfaces que estão ativas.
Ok, estou tentando dividir minha pergunta anterior em partes:
Esta é minha referência: link
tunneling ubuntu -> debian 1. ssh -i green.pem root@$HOST echo 1 | tee /proc/sys/net/ipv4/ip_forward echo "PermitTunnel yes" > /etc/ssh/sshd_config /etc/init.d/ssh restart ctrl-d logout 2. sudo ssh -i green.pem root@$HOST -w 0:0 -o Tunnel=ethernet ** logs in, no errors ifconfig there is no tap0 or tun0 interface ip addr show tun0 Device "tun0" does not exist
Deverá existir uma interface neste ponto?
