Ethernet problem

**apache_2o0o6** · 01-09-2007, 02:39 AM

i hava an ethernet card and my FC6 has known that as eth0
but when i try to start a connection via the ethernet, the following error
occurs

================================

Error for wireless request "Set Encode" (8B2A) :
SET failed on device eth0 ; No such device.

Determining IP information for eth0...SIOCSIFADDR: No such device
eth0: unknown interface: No such device
eth0: unknown interface: No such device
failed.
================================

i didn't misconfigure it and it's all automatically done by the OS;
how should i fix the problem!

it's amazing taht the device manager and terminal based setup
kknows the card and also it's name
thnX

It seems as if its being detected as a wireless card. You could try running system-config-network, deleting the card on the list, and then making a new ethernet connection.

**apache_2o0o6** · 01-09-2007, 07:29 AM

i have already tried this way but it isn't useful!
is there any other way to perform a lower level configuration?

At minimum, /etc/sysconfig/network-scripts/ifcfg-eth0 should contain the following for a simple dhcp connection:

Code:

DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes
TYPE=Ethernet
USERCTL=yes

/etc/modprobe.conf needs an alias for the driver module for your ethernet adapter. If you know the driver for your card, add it here:

Code:

alias eth0 your_driver

Run the following from the command line, and you should be good:

Code:

ifup eth0

**apache_2o0o6** · 01-09-2007, 05:32 PM

many thnX,
but I don't know the driver name

my card is: Broadcom 440x 10/100 Integrated Controller

**dkeav** · 01-09-2007, 06:01 PM

b44 comes to mind

**saikee** · 01-09-2007, 07:53 PM

Have you tried to click at the FC6 desktop
"system"
"administration"
"Network", then enter root password
You should have a network conguration screen. If eth0 appears there you can highlight it, edit it and activate it.

**apache_2o0o6** · 01-10-2007, 05:29 AM

thnX for help!
But none of these ways became useful

i think that the device is not even known and does not exist in "/dev"
directory!

there is another point ! when i perform probe action for probing MAC address

in system-config-network ---> edit eth0
the following error occurs:

[Errno 19] No such device

and in startup page where the starting services are listed
there is some failure error like "device eth0 doesn't seem to exist..."

it's a little amazing and fun does Linux just imagine an ethernet card in it's dreams???

**saikee** · 01-10-2007, 05:38 AM

You can always spend a few dollar to get the cheapest nic, say a Realtek 8139, to bypass the recognistion problem. Think it costs Sterling 4.5 here and would be about US$ 8 to 9 in the State. Linux generic drivers work like a magic on the commonly available components.

**apache_2o0o6** · 01-10-2007, 10:30 AM

i am working on a dell inspiron 8500 laptop
and here inside iran it's a little hard to find laptop hardware!
changing the hardware couldn't be the final way because the linux has never disappointed me!!
i was working with this card on fc3 - fc4 - fc5 - mandrake - ubuntu ......

but there is a small problem with FC6
i believe that won't be left unsolved!
lots of thanks

That is because network interface cards have peculiar enough behavior that warrants a break away from the "everything is a file" UNIX paradigm. Nonetheless, it should still work fine.

Can you please post the results of:

Code:

lsmod

Code:

ifconfig -a

Code:

cat /etc/sysconfig/network-scripts/ifcfg-eth0

**blobaugh** · 01-11-2007, 01:08 AM

another check you can do is looking at the output of dmesg.

This is weird --- the driver module had already been loaded, yet there isn't a real ethernet driver in ifconfig -a. No wonder the system is haywire...

As blobaugh says, a dmesg is required. I cannot confirm if b44 is indeed finding the ethernet card. And how did you know your card is a Broadcom?

**apache_2o0o6** · 01-11-2007, 09:09 AM

i know the name of card by simply using "lspci" command!
and the aliases inside modprobe.conf is originally generated by linux!

i'll send you the dmesg in the next post
thnX
