Conecte o beaglebone black executando o Debian Image 2015-11-12 para o PC através da Ethernet.

Question

Eu tenho o Beaglebone alimentado por 5V e o ethernet em uma porta aberta no meu PC. Eu adicionei as linhas a / etc / network / interfaces

auto eth0
iface eth0 inet static
   address 192.168.1.80
   network 192.168.1.0
   netmask 255.255.255.0 

Isso aparece com

root @ beaglebone: / var / lib / cloud9 # ifconfig

eth0      Link encap:Ethernet  HWaddr 04:a3:16:b3:c3:b7  
          **inet addr:192.168.1.80**  Bcast:192.168.1.255  Mask:255.255.255.0

Mas quando tento fazer o ping 192.168.1.80, fico com o Host Inalcançável.

Mesmo quando eu faço logon através da serial, eu obtenho

Debian GNU/Linux 7 beaglebone ttyGS0

BeagleBoard.org Debian Image 2015-11-12

default username:password is [debian:temppwd]
The IP Address for eth0 is: 192.168.1.80
The IP Address for usb0 is: 192.168.7.2

O que estou fazendo de errado?
