I cannot know for certain what is installed on your system. The usual
command for checking eth* interfaces (not "devices") is
ifconfig -a
Some newer, or stripped down, Linux systems may lac
$> this command. In that
case, see if you have the command "ip" on your system. If you do, the command
ip link show
should give you information about the interfaces.
I am assunming here that your Linux kernel has in it, or loads modul
$>s that
provide, support for the actual NICs in your system. If not, you don't have
the eth* interfaces, and you'll need to do something to create them. I
cannot say what without knowing a few more things, namely ...
what sorts of NICs
$>they are (you may have to open the case to find
out, or the command "lspci" may tell you)
what Linux distrubution and version you are using
what Linux kernel ("uname -a") you are running, and whether it
is
a stock or a custom-co
$>piled kernel.
You should be logged on as root to execute any of the commands I listed
above.
As to whether you should "unplug" one ... it depends on unreported details
of your setup. Again, approaches vary a lot from one Linux distro to
anoth
$>r, but newer versions are tending to use /etc/network/interfaces as
the config file for the eth* (and some other) network interfaces. You might
see if you have such a file and, if you do, what it says about setup of
eth0 and eth1. Which of them (
$>r are both) is set up here to get an IP
address via DHCP?
And am I correct in inferring that both eth* interfaces are connected to
the *same* network (the same LAN, probably)?If they are, you probably want
to ask the sysadmin if the network is
$>setup to allow the interfaces to be
bridged, so they can work together to double your connection speed. If they
are not, advising you as to what you should do depends enough on what they
are connected to that no advice can make sense without your
$>providing more
information.
