Copy this code and paste it in your HTML
  1. ### Edit /etc/network/interfaces (in this example setup I will use the IP address 192.168.178.50 for eth0):
  2.  
  3.  
  4. # This file describes the network interfaces available on your system
  5. # and how to activate them. For more information, see interfaces(5).
  6.  
  7. # The loopback network interface
  8. auto lo
  9. iface lo inet loopback
  10.  
  11. # This is a list of hotpluggable network interfaces.
  12. # They will be activated automatically by the hotplug subsystem.
  13. mapping hotplug
  14. script grep
  15. map eth0
  16.  
  17. # The primary network interface
  18. auto eth0
  19. iface eth0 inet static
  20. address 192.168.178.50
  21. netmask 255.255.255.0
  22. network 192.168.178.0
  23. broadcast 192.168.178.255
  24. gateway 192.168.178.1
  25. #optional
  26. #dns-nameserver 102.168.178.1
  27.

  31.  
  32. nameserver 192.168.178.1
