Hi, I've been assigned a PC with two eth devices, What utility can I give them? or is better if i unplug one, my network is configured to assign an IP address via dhcp.
As you can see I'm a Linux newbie in network thems... TKS
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 lack 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 modules 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-compiled 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 another, 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 (or 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.
