Angry Fedora Core 2 Unable to activate Network device eth0


Hey All,
I'm fairly new to Linux tried Debian woody first now I've Installed FC2. Everything Seems great but I cant activate eth0. I have a cable modem, and I must obtain IP from provider. I can't seem to figure out how to setup this device or the connection to my provider.
Can anyone give me a hand?

ifconfig -a

It appears to have been detected with an IRQ=9 IO=0x6800
now I tried to manually input those numbers into network settings of KDE with the following errors Command failed: /sbin/modprobe 3c59x Fatal error inserting 3c59x(/lib/modules/2.6.5-1.358smp/kernel/drivers/net/3c59x.ko): Unknown symbol in module, or unknown parameter(see dmesg). the dmesg I show here is from the original configuration and not after the error.
I saved and rebooted and it prompted me to remove the card and add a different card (the same slightly different) after login two cards showed up in networking eth0 the original I changed and eth1 that I was prompted to add. I then removed the added and reverted the original to an unknown IRQ and no IO address. Which is the way it was from installation.
During boot in original installation configuration it tries to bring up interface eth0 and then determines IP info. for eth0 which takes longer than other started services, then FAILS and continues on loading also failing smartd services which I do not know if that is related to eth0 or not.

HELP please I'm getting frustrated with this eth0 problem.

Wolfy, try creating ifcfg-eth0 with:
DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes

Then run:
service network restart

As in my first post #1 it is already configured that way.
Do you mean take out;

HWADDR=00:60:08:AD:81:8D

And

TYPE=Ethernet
USERCTL=no
PEERDNS=no
IPV6INIT=no

From the list save and start network?

wolfy -- according to your first comment about how you need "obtain IP from provider", are you saying that you are using a static IP address, or that you need to dynamically retrieve the IP address via DHCP? If it's the former, clearly you would need to know its value in order to configure things correctly. Can you clarify which it is?

Additionally, if you are you are using the 3Com NIC, is the appropriate module loaded (which I believe would be 3c59x)? If not, have you tried loading it with the insmod (or modprobe) command? -- J.W.

MEPIS, knoppix

Hi,

I was able to get a cable modem autoconnected to the ISP(Comcast) using both of the live evaluation CDs MEPIS and knoppix. I plugged the cable modem into the laptop before booting.

Both of these distros are Debian-based, since you seemed to want to use Debian before. Since they start as live evaluation CDs, if they don't work, nothing is lost, as nothing is written to the hard drive. If they do work, both are relatively easy to install to the hard drive. MEPIS is, in fact, the easiest linux installation I have ever seen.

In your ifcfg-eth0 file, you have specified DHCP, which means you are asking the ISP to provide you with a dynamic IP address. This is fine, and easy. If, as a previous person has posted, you need a static IP address (a specific, fixed address), then the DHCP setting is wrong, and instead you need to enter that static IP address. I also noted that you have a hardware address specified. Is this required by your ISP?

If you are truly using DHCP, then either MEPIS or knoppix should autoconfigure you cable modem and autoconnect to your ISP.

did you try: "ifup eth0"

and I also have cable modem and for dhcp i use small deamon called udhcp, which (strangly) works very fine. I run it at boot time and voila - net is here

Ouch!!!!

Sorry J.W.
I'm still NEW and I did not mean to upset any balance.
I'm just very fustrated at this problem. I thought that it would help to advertise the issue a little but it seems that was the wrong thing to do, I apologize.

to answer your question:
I need to obtain an IP from the dhcp AND I have to use a specific MAC address to do so.
I've been able to spoof my wife's machine which is using WIN$H!T 2000 and and as long as she is plugged in and not me her machine surfs fine.
I've been able to find out how to secifiy an HW for my Linux box but it does not help.
I've disabled obtain at startup to resolve a failure issue when trying to obtain IP info.
that the system does at startup if I don't stop it. If I don't stop it, it FAILS




Secondly, Yes I belive the right driver is being loaded but can't be sure.
It is although correctly naming the hardware componet by itself.
No, I have not tried nsmod (or modprobe) command.
Do you think that will make a difference? Even though though the card is correctly Identified?

As darthtux told me about Debian, every distro has it's problems. I believe him. Though with FC2 I have had only this problem to deal with as of now. I'd like to stick with this distro for now if possible.

As for "ifup eth0" doesn't that just bring up eth0?
I've tried that I think, but just not with that command, am I missing something in the command?

P.S. J.W. I will remove the offending post immediately, sorry again.

if you did configure eth0 and then you did NOT brought it up via (ifup eth0) then everything is meaningless. After configurated eth0 you have to bring it up. Which card do you have and which driver is loaded?

If using FC2 why don't you just go Start --> System Settings --> Network and take a look at your eth0, in this screen you just highlight eth0 and click activate, also you can check under the hardware tab as to what it is calling your network card, plus you may have to put in the dns servers ip address from your isp provider.

Wolfy -- no problems, don't worry about it. The reason we try to keep discussions in a single thread is simply because it's a lot easier to have all the info in one place than it is to have useful answers scattered across multiple threads. Note also that if you've got a post that has not received a response in over 24 hours, it's OK to go ahead a bump your own thread (meaning that you post a reply to it yourself) Because threads in a forum are sorted by the last reply date, this will cause your original thread to regain the same visibility as a brand new thread.

That being said however, if you've got an unanswered post, please do not abuse this privilege and bump the thing every 15 minutes, as that is against the LQ Rules and would be severly frowned upon. Please wait at least 24 hours after the latest timestamp before bumping your own post. -- J.W.

Does: [/sbin/ifconfig eth0 up] do the same thing as [ifup eth0]?
If so than I've been there done that.

And as far as system settings whithin a GUI, I tried that too it was unable to activate the device. I called my cable provider last night and no IP's or DNS names are needed or could be given to me. Their statement was the device should be configured to obtain all information automatically, further they're not able to give support for linux.

I have a few different NIC cards laying around I could try one of those instead.
