No responden los pings, y estoy seguro de que la red esta bien, porque si conecto el internet directo (Sin pasar por el proxy), si tengo conexión.
Probé a interconectar el server con un cliente mediante un cable directo y no hubo respuesta, después conseguí un cable cruzado y tampoco la hubo. Desactive momentaneamente eth0 (La de internet), ya que la necesito, y consegui el log: > ^Ccompaq-pc@compaq:~sudo gedit /etc/network/interfaces > compaq-pc@compaq:~$ sudo /etc/init.d/networking restart > Running /etc/init.d/networking restart is deprecated because it may not > enable again some interfaces ...
