Criei túneis SSH no passado, mas estou tendo problemas com o OSX. Eu estou olhando para pegar a porta 80 de um site e direcioná-la para meu localhost: 8080 (ou qualquer porta, na verdade). Quando eu executo este comando
sudo ssh -v -L 8080:<cloud_ip_address>:80 root@<cloud_ip_address> -N
Eu recebo o apache padrão "funciona!" página ... Mas não a página web da porta 80 real.
Eu também tentei essa variação, que me deu os mesmos resultados:
sudo ssh -v -L localhost:8080:<cloud_ip_address>:80 root@<cloud_ip_address> -N
Por que não estou obtendo a típica página html da máquina remota (que está executando um aplicativo da web)?
ATUALIZAÇÃO:
Marcs-MacBook-Pro:~ marcleonard$ sudo ssh -vvv -L 8080:<cloud_ip_address>:80 root@<cloud_ip_address> -N
