I need to configure a network interface permanently eth1 and to change the MAC address with the specified format : AA:BB:CC:DD:x:y, before the interface is up. A=1;B=2;C=2;D=2;x=6;y=8.

I wrote in /etc/network/interfaces:

auto eth1  
iface eth1 inet static  
address 10.6.8.200  
netmask 255.255.255.128  
gateway 10.6.8.129  
pre-up ifconfig eth1 hw ether 1A:2B:2C:2D:6:8

I don't know what I'm doing wrong.

  • This looks correct and works for me. I'm looking for the issue your question is about but you didn't write what didn't work and how you tested it. – Marcin Kaminski Dec 20 '12 at 18:10

auto eth1

This tells Ubuntu to use DHCP for eth1. What happens if you remove this line?

  • The system is ok with removing this line but removed or not something its not working.I suppose to be something wrong in the MAC changing... – Michelle Dec 20 '12 at 18:00
  • @orzechowskid Not true. `auto eth1` does NOT have anything to do with the IP configuration assignment method. Its purpose is to mark interfaces to be enabled during boot or when `ifup -a` is used. – Marcin Kaminski Dec 20 '12 at 18:03
  • Thank you but i still need to know if the changing of the MAC address is wrong or i didnt understood it corectly? – Michelle Dec 20 '12 at 18:04
