The real manual method has been described above, but since you write you don't have DHCP, I think you rather would like to know what to do to give your box a static IP address and assign this IP address at boot time automatically.

Well, here is how:. This file is read by the Ubuntu boot scripts which in turn configure the network according to that file. The first two lines are standard and may already look similar on your box.

You may be interested especially in the rest of the file: These lines define a static network configuration to eth0 without DHCP , and this static configuration gets active automatically on every boot. You don't need IP address for capturing packets in promiscuous mode when you want to capture all traffic, not just traffic destined to your computer. You can put that interface up using command.

However let me show you the usage of mii-tool. Run the following command:. I run both commands in my linux machine and here is the screenshot. This command can also be used to find the Ethernet Link Status. If you know better ways to find Network card information, please do share it with us.
