Unable to Network connect Internet

[simbiwa]

I am using ASUS P4V8X-MX motherboard with a built in Lan, everything was working perfectly , I was able to connect to internet and my area network using the ethernet conection.

The problem started when I tried a  128 mb Graphics card in the AGP slot.
The system at the boot time cried out KERNEL PANIC !

I removed the graphics card and went back to the way I was using it, now I am unable to see the ethernet or lan and am unable to connect to the network or internet.

I tried ifconfig -a and I can only see details of LO and nothing else

As I have XP also installed , there is no problem, Lan is working fine.

How can i make |Kubuntu see the builtin lan and be able to connect using the ethernet to network.?  Any help will be greatly appriciated.

Re: Unable to Network connect Internet

Hi,

I think, first you should try to see if the system is still recognizing it. ie : type lspci and/or lshw to see if the card is there.
If yes, check the /etc/network/interfaces file to see if your interfaces are still present, maybe also /etc/iftab.
Then, try sudo ifup <name of interface>
And look what is said.

Hope it will help.

How to bring up the eth0?

Re: Unable to Network connect Internet

okay, the listing for eth0 is a static IP. are you sure that this IP is static and not dynamic?
Here's the IP ifconfig listed for eth0: address 192.168.35.15

if it is static, perhaps you can manually run this in a Konsole:
sudo /etc/init.d/networking restart

what errors are reported (if it fails to bring up your ethernet link)?

if it really should be dynamic, then change it using kate editor (as root)

open a Konsole and type: sudo kate /etc/network/interfaces

edit the entry for eth0 so it looks like this:

auto eth0
iface eth0 inet dhcp

Now again run from a Konsole: sudo /etc/init.d/networking restart


hope this is helpful. If not, post back.

Hi a_Hippie

Thanks for the reply , Yes the Ip is static and thats what I was using before .

I tried the command you provided and the results are as follows:

sudo /etc/init.d/networking restart

Re: Unable to Network connect Internet

Hi,

For me, it looks more like this interface is not mapped to eth0, can you check result of ifconfig -a and also the content of file /etc/iftab please ?

Cheers

Re: Unable to Network connect Internet

HI sky

If you read my fisrt post in this thread I have mentioned that the result of

Ifconfig -a shows the details of lo only and nothing about eth0


and the entry in the etc/iftab shows the MAC adress in 12 digits which is the correct MAC adress .

How do I map this eth0?

[sky]

Re: Unable to Network connect Internet

Sorry :/
To register this device to be this one, you should set it in /etc/iftab like this :
eth0 mac xxxxxxx

Then restart, and it should appear

Re: Unable to Network connect Internet

Hi all:

Here's what my /etc/iftab looks like.. remember, both wifi and ether are DHCP:

# This file assigns persistent names to network interfaces.
# See iftab(5) for syntax.

eth0 mac 00:16:d4:2f:05:81 arp 1
eth1 mac 00:13:02:5b:ec:2b arp 1

hth

Re: Unable to Network connect Internet

Hi

my /etc/iftab file is :

#This file assigns persistent names to network interfaces.
# See iftab(5) for syntax.

eth0 mac 00:15:f2:d3:8a:a7 arp 1


I removed the arp 1 and restarted and checked the ifconfig -a  but apart from details of lo(loopback) nothing about eth0.
I have again inut arp 1 after seeing the post from a_hippie and restarted but no use

Any more sugestions please , I have started  pulling down my hair. 

a_hippie what is "hth" hope that helps??maybe?

Re: Unable to Network connect Internet

Sorry I don't get it.. If the mac is the good one and you don't get the eth1 shown in ifconfig -a, it should be because of error in dmesg or any other logs in /var/log maybe...
Maybe you check this ?
You can see the card by lspci command ?

Good luck

Please bear with me as I am a newbei , I do not get this "dmesg or othr logs in /var/log"

Where or how do i check that?

As for lspci , I can see the ethernet card , and by lshw i get this :

ah, good question. log files reside in /var/log. the important ones for us today are:
/var/log/dmesg
/var/log/syslog

You can use "less" to read them: less /var/log/dmesg as an example
use the letter "q" to exit the "less" text reader program. Yes, all these work in a Konsole shell.

dmesg is very important, it is what happened right after you turned on the power to your computer. everything that happens durring boot up is logged into this file. here you should see a reference to your ethernet card--and also perhaps errors with it.

/var/log/syslog is another great file. Here you will see things that happen to the system as it is running--if you plug in a USB drive, a new entry will be added showing how the system sees this device and what it did about it. A GREAT program to watch this file in real time is:

tail -f /var/log/syslog

To cancel the "tail" program, use CNTR+C (control c)

again, this command is run inside a Konsole shell.

hth!
