Ok, I'm trying to break my previous question down into parts:
This is my reference: https://help.ubuntu.com/community/SSH_VPN
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
Should there be an interface at this point?
In response to a comment:
