eth0 is not found at ifconfig.And when i am writing ifconfig eth0 it says : Error fetching interface information: Device not found. I haven't done any of the internet configuration and i dont know how.
When i am writing net-setup it says: Net-setup command not found.PLEASE help. I don't know anything.And i dont know anything about how to emerge packages,drivers ect and build them to kernel.i am new in gentoo.

eth0 is just a description name. and you can change the name at your desire, for example you can name your interface 300sparta300, if you want it...

be root when executing the following commands....
"ifconfig -a" will give you all your network devices, so if you need any help, please post the output 1:1. Tell us more about your current setup:
1. wireless/wired
2. what network card do you have (post the output of "lspci" if you are not sure)
3. what do you want to achieve (basic setup to connect to your router or maybe setup a vpn or to use ppp)

if you dont give us this information there is no way that we can help you...

It would help us to help you if you would specify your computers manufacturer and model so that we can find out what kind of hardware we are talking about.
Knowing which installation medium you used to boot your machine would also be helpful, as would knowing whether you followed the instructions in the Gentoo Handbook (x86 / amd64) to the letter.

I can't stress enough the importance of following every instruction (and reading them carefully) in the handbook, especially if you are new to Linux (or at least a source-based Linux distribution) which I gather that you are from reading your post. Gentoo does have an assisted install option, actually both a graphical and a console-based ones. They did not work very well when I tested them a few years back but they might have improved since then. That might be a preferable alternative to the normal "hard-core" unassisted install method for someone not used to the command line. Both assisted alternatives should be available as icons on the Gentoo LiveDVD desktop.

The reason why I'm interested in which installation medium you are using is because as far as I know net-setup is included in all Gentoo LiveCD/DVD's. Are you sure you didn't just capitalize the word wrong ? For instance Net-setup ? Unix/Linux IS sensitive to capitalization in contrast to MS Windows (95/98/NT/2000/2003/XP/Vista).
Are you logged in as root or as the gentoo user ? If you are logged in as gentoo (default for graphical LiveCD/DVD environment I believe), the correct path to where net-setup is located might not be set for that user. To check which user you are logged in as, type the following at a shell prompt..."id -a" (without the quotation marks of course).
To become the root user you can type the following at a command prompt... "sudo su -". That should make your current shell a root-shell.

If we assume that you just capitalized wrong or are not the root user and go on to the detection problem, IMHO there might be two reasons...

Network Interface Card

eth0

udev

Alternative 2 is the easy one to check and fix. Type "ifconfig -a" in your console as root, just as Zucca suggests and post the output here.

Alternative 1 is a bit of a problem to solve for a novice as it requires setting up the installation environment using a non-Gentoo LiveCD/DVD with access to newer drivers. For example Dell's current lineup of Latitude and Precision laptops can not be installed with current 2008.0 Gentoo LiveCD/DVD boot media because of the lack of support for the correct Intel e1000e NIC driver. This is something that I believe the current Gentoo release crew are very aware of and is the reason why the release cycles/methods are being reworked. If this is the reason why you can't get it to work, I would suggest that you search the Google for a guide on how to install Gentoo using a non-Gentoo boot media.

I found a link that explains how to install Gentoo using Knoppix, but the same principles apply to any liveCD/DVD. I have had success using System Rescue CD which contains the new and fixed e1000e NIC drivers for my Dell laptop.

Cheers

ok, now what about the output of ifconfig -a?
from what I understand you have 2 network cards, which one are you going to use?

sk8harddiefast · Guru Joined: 15 Feb 2009 Posts: 335 Location: athens

if config shows me only lo !!! i want both of them work but firstly rtl !!!! there i always connect the internet. cable (sorry but i dont speak english very well)

When defenderBG wrote "please post the output 1:1" he meant to please post the whole output of the commands.
Please open a shell and post the unabbreviated output of the following commands...

id -a
uname -a
ifconfig -a
lspci

Please use the [ code ] tag to enclose the output for each command as it makes it easer to read...

Did you build your own kernel, or use Genkernel?

what is the output of modprobe r8169

Yep, indeed you have 2 wired cards:
02:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8056 PCI-E Gigabit Ethernet Controller (rev 12)

05:04.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8110SC/8169SC Gigabit Ethernet (rev 10)

I am not sure what the module for the first card is, but for the second one it is r8169. You need to "modprobe r8169" as root. If it does not show any error message, then do "ifconfig -a". Probably you will see eth0. If so, "cd /etc/init.d && ln -s net.lo net.eth0 && /etc/init.d/net.eth0 start". Note that you should first confirm that the network cable is plugged in the right card. To be sure, after the modprobe look which of the two adapters blink/has light and put the cable there. If you are able to connect to the internet, then make the computer connect every time you start it:
echo r8169 >> /etc/modules.autoload.d/kernel-2.6
rc-update add r8169 default

if it fails for some reason, report where it failed and what the output is.

Thanks for the info sk8harddiefast.

Just to clear up a thing that xbmodder's post made me think about.
Is your install complete and it doesn't work...OR...have you just started the install and the liveDVD doesn't find your NICs ?

From what I can find on the net, both cards are supported by Linux...

Marvell Technology Group Ltd. 88E8056 PCI-E Gigabit Ethernet Controller:
Supported by sky2 driver or sometimes sk98lin driver depending on which motherboard you are using. Both drivers are known to have some problems. There is a wiki page dedicated to the sky2 driver on the Gentoo wiki that shows which kernel options you have to enable to compile the sky2 driver. The sk98lin driver can be downloaded from Marvell's driver search page.

Realtek Semiconductor Co., Ltd. RTL-8110SC/8169SC Gigabit Ethernet:
This NIC is as defenderBG wrote supported by the r8169 kernel driver, however, that driver has some serious problems in kernels below 2.6.25 and you are using 2.6.24-gentoo-r5.

The commands defenderBG wanted you to run should be...

Happy happy joy joy! It works

Please edit your top post and add "[SOLVED]" to the subject, that way people knows that it has been resolved without having to read through the whole thread.

Don't forget to do the other commands that defenderBG mentioned...

Please post the following info...

rc-status --all | grep -E 'Runlevel|net\.'
ls -l /etc/init.d/net.*
cat /etc/modules.autoload.d/kernel-2.6 | grep -v '#'
cat /etc/conf.d/net | grep -v '#'

As before, post all of the output in neat little [ code ] boxes
