NetWork interface trouble...

[Gilberto Nunes]

Hi Serge

First, it is necessary to me apologise by my poor badly English...
I really sorry...
But this issue make me very confused, because I never replace the NIC's,
also never replace the mother board....
The MAC address is the some of initial instalation...
But, I will try do what you suggest with udev trigger command...

Sorry for all disturb..

Thanks
