failed to bring up eth0

aspinnler · 02-26-2006, 02:28 PM

Hi, I have both Debian x86 and Ubuntu x86_64 installed on my computer.

Just today, Debian suddenly cannot setup my ethernet interface.
However, Ubuntu doesn't have any problem.
Also, I have an on-board gigabit NIC.

when I run the 'route' command in debian I get no output in comparison to the command being run in Ubuntu:

PHP Code:

Also, here's my output from 'ifup eth0' in Debian:

I'm really lost about how networks work......

Hello.

All I can figure out from those messages is that somehow it's not getting an IP address automatically.

Please post the output of "ifconfig eth0" in both Ubuntu and Debian.

Have you tried giving it a static IP address?

Hope this helps.

dracae · 02-26-2006, 08:39 PM

Have you tried ifup eth1? The modules might be loading in a different order.

aspinnler · 02-26-2006, 09:20 PM

From Ubuntu-- 'ifconfig eth0'

PHP Code:



alex@dhcp-128-194-69-142:~$ sudo ifconfig eth0

From Debian-- 'ifconfig eth0'
Also, now when Debian boots up it successfully configures the ethernet
interface, or so it says. But the output below shows dropped pakets.

PHP Code:

Alright, from Ubuntu:

PHP Code:



alex@dhcp-128-194-69-142:~$ sudo ifup eth1 
Password: 
Ignoring unknown interface eth1=eth1.

dracae · 02-26-2006, 09:27 PM

In debian run
ifconfig eth1 0.0.0.0 && dhclient eth1

I have two ethernet cards also. They seem to randomly load in different order from time to time.

aspinnler · 02-26-2006, 09:52 PM

Well, I don't have two ethernet cards......actually.

dracae · 02-26-2006, 10:54 PM

Ohh, I read

Also, I have an on-board gigabit NIC.

as an additional nic.

On debian make sure you have in /etc/network/interfaces

iface eth0 inet dhcp

then run ifup eth0

ifconfig eth0 will not invoke the dhcp client.

aspinnler · 02-27-2006, 01:23 AM

Yeah, yeah.

I looked at my etc/network/interfaces files in Ubuntu to compare it to Debian when this problem first arose.

Anyways, I already had the iface....lines in the files.

I've also tried running the ifup eth0 command from Debian-->my first post has the output from that there.

**I asked a friend of mine what he thought about my problem. I used modprobe for my marvell ethernet adapter-- sk98lin. Now I think maybe need to change the permissions (chmod) of something, like say that modules.??? Does this make sense?

Anyways here is lsmod output, just in case:

And yes, I should remove the unused modules.

And yeah I don't see the sk98li module in the above list. I guess Ubuntu is using something else for my ethernet nic.(?)

DaneM · 02-27-2006, 01:26 AM

I think dracae is in the right track, but if you can't get that to work, let's try doing a static IP.

Comment out the line in /etc/network/interfaces (by putting a # in front of it):

Code:

iface eth0 inet dhcp

...and put this in:

Code:

iface eth0 inet static
address 128.194.69.142
netmask 255.255.255.0

then do "ifup eth0".

--Dane

DaneM · 02-27-2006, 01:38 AM

Is sk98lin the module name? If so I don't see it listed. Do you get an error message when you try to modprobe it? If so, please post it.

--Dane

aspinnler · 02-27-2006, 01:43 AM

Nope, no error message during modprobe.

Also, using static ip address wasn't successful.

**Ya know in the time I've spent on this problem I could have just reinstalled Debian...

farslayer · 02-27-2006, 09:20 AM

so are there any errors showing in /var/log/dmesg in relation to detecting the ethernet controller ?

the reason I ask is that when you show ifconfig for the debian box the encapsulation is UNSPECIFIED and the MAC address for he card is borked (wrong).. it looks as though the system is not detecting your hardware properly.. you can set all the static IP's you want and renew DHCP all day long and it's not going to work until you fix the fundamental problem of the hardware not being detected properly..

Quote:

Ubuntu
Link encap:Ethernet HWaddr 00:0D:61:7C:53:AD
Debian
Link encap:UNSPEC HWaddr 00-0D-61-00-00-79-78-16-00-00-00-00-00-00-0$

Those HW addresses should be identical.. not just he manufacturer ID portion (the first three octets)

What does lspci show ? (does it list the correct network card in your machine ?

Is the proper module for that card being loaded ?

is your system detecting a firewire port as an network interface controller and your ethernet controller has moved from eth0 to eth1 ? (happened to me on Debian already.. )

Review /var/log/dmesg for entries related to the Network card detection. post any relevant lines

aspinnler · 02-27-2006, 11:41 AM

Here's what was in /var/log/dmesg:

Code:

ieee1394: Initialized config rom entry `ip1394'
ohci1394: $Rev: 1223 $ Ben Collins <bcollins@debian.org>
...
ohci1394: fw-host0: OHCI-1394 1.1 (PCI): IRQ=[225]

ip1394: eth0: IEEE-1394 IPv4 over 1394 Ethernet (fw-host0)

As for lspci, yes, this is correct:

Code:

0000:02:0b.0 Ethernet controller: Marvell Technology Group Ltd. Yukon

farslayer · 02-27-2006, 11:56 AM

eth0 = ieee1394 = FIREWIRE port there is your issue..

the system thinks the Firewire port is eth0 so you need to figure out what module is actually needed for your NIC and ensure it is being loded. at which point the Marvel controller should come up as eth1.

Looks like DaneM hit it on the head with the module needed.. sk8lin

Just curious what kernels you are running in the 2 OS's is Debian using an older kernel or are you up to 2.6.15 ? that may explain why Ubuntu can use it but Debian isn't.

Linux driver for sk8lin in case you need it..

aspinnler · 02-27-2006, 12:20 PM

Ok, so went into Debian and..

1) modprobe sk98lin
--no errors, all good
2) ifup eth1
--Ignoring unknown interface eth1=eth1.

Do I need to put the module in some script that loads at boot?
