I have recently acquired an old computer that I tried to install Ubuntu 12.04.3 server onto, however the system could not be booted into any external medias (USB and CD drives). So I hooked the hard drive into another computer of mine and installed the OS, then when I booted the server up it could not ping any web address or DNS from the internet. I narrowed the problem down to the fact that the Ethernet port has not been configured. to back this up I ran:
ifconfig -a | grep eth
and the result was:
eth1 Link encap:Ethernet HWaddr 00:08:74:c3:2f:df
next I ran:
ifdown eth1 && ifup eth1
and the result was two lines. the first line result was:
ifdown: interface eth1 not configured
and the second line read:
Ignoring unknown interface eth1=eth1
I just need to get this connected to the internet, but it is not enabling the Ethernet port, are there any commands that will enable me to manually activate the Ethernet so I can get internet connection?
The machine is a Dell Dimension 2350.
