Delete an interface

First some history, I 'ghosted' a Linux image to a computer and at the
same time replaced the Gigabit 10/100/1000 NIC. The original NIC was a
dual i/f (no name brand). I replaced it with a better card (also a dual
i/f).

Now the problem is, that all four of the eth's are shown in 'ifconfig'.
Let me clarify, there are four i/f's listed, they are: eth0, eth1,
eth2, and eth3. My presumption is that I should have only: eth0 and
eth1. That is, two eth's, one for each of the two interfaces that are
currently attached.

My question is should I get rid of the unused eth i/f listed in
ifconfig?
And if so, how?

The cause for alarm is that I have no way of knowing which one is the
real i/f?

Thanks,

Delphinus

Hi Delphinus .

give
ifconfig eth0 down
ifconfig eth1 down
ifconfig eth2 down
ifconfig eth3 down

This will remove all interfaces.

Now give

/etc/init.d/network restart

now give ifconfig.

two interfaces will shown
and one loopback will shown.

now set 2 ip address for each one as

ifconfig eth0 A.B.C.D
ifconfig eth1 A.B.C.D

This is enough.

And network restart should have given them IP addresses already.

Better be different addresses for each.

Sorry guys.

we have to give different IP address for the two cards.

I used A.B.C.D just for IP address format, as a skeleton.

Thanks Unruh.

And THANKS to you both for your help!
