knoppix 3.4 kernel 2.6 ethernet help!

[secknet]

Hi i'm italian and sorry for my english!
I have a problem: i installed knoppix 3.4(the last) on my hard disk and works fine but my network connection doesen't work.
I have two ethernet card, one is sis 900(integrated) and one is realtek 8139 .
When is set the netowrk parameters not works , wich ifconfig from shell is the same!
I see if the module is ok but lsmod: no module installed for sis and for realtek.
Which modprobe the module is loaded but not working the network connection!!!
This problem only if i start knoppix with kernel 2.6.6 and the kernel boot report that i have 3 ethernet interfaces!!! i have two.
with kernel 2.4.26 is ok but when i shut down knoppix and restart i lose network configuration and is necessary to rewrite the configuration!
Anyone can explain to me to solve the problem with kernel 2.6.6?
And which method can i use to save a configuration of network card without rewrite all any moment?

Thanks in advance

You may not use the modules for 2.4.x with 2.6.y, nor may you keep the driver during reboot.

The 2.6.y - drivers are located in /lib/modules/2.6.y/... and
the 2.4.x - drivers are located in /lib/modules/2.4.x/...

They aren't compatible.

If you enter: ifconfig eth0 or ifconfig eth1, what do you get?

And do you have a module 8139too.ko?

if you modprobe 8139too, what is the result of lsmod | grep 8139

I have connection problem with 3.4 too.

I am running Knoppix 3.4 on HDD. When I first boot I have no connection.

lsmod and ifconfig gives the following;

I am running Knoppix 3.4 on HDD. When I first boot I have no connection and ifconfig gives the following;

The I go to the Knoppix Network Card configuration and select eth0 and yes to DHCP. I am then connected OK and ifconfig gives the following;

When I reboot my connection is gone again

I have seen some threads hinting that all this may be caused by windows security updates but that is sure hard to believe.

[turbines]

I just ran both 3.3 and 3.4 booting from CD and both still configure internet connection through my eth0 automatically. Something has happened during the HDD install

[user unknown]

Are you sure, that the dhcp-setup is correct?
Running netconfig every time is no solution. The networkcard is found, as you see, it only lacks an inet adress.

You may set it manually like this:

ifconfig eth0 192.168.100.11 up

[turbines]

I am a noob and I don't have a clue as how to determine if dhcp is set up properly. Can you help me with that.

I know that when I select eth0 from the Knoppix network card configuration and then click on OK for dhcp broadcasting it has no problem finding the IP address and it then connects immediately

[user unknown]

My first question is: Who serves that ip-adress?
Is it a different PC, or a device like a dsl-modem?

I have an mini-lan: one desktop and one, sometimes two laptops.
And a dsl-modem to connect to the internet.

From the dsl-modem, I get an ip-adress for ppp-usage.
But I still have a lan-adress for the same network-card (192.168.0.3).

For a small lan, an dhcp-server is overkill - just set a static ip in your initscripts.

[turbines]

The IP is the static IP chosen for the local PC that Knoppix is running on

[user unknown]

And why do you want to use dhcp? 'd' means 'dynamic' which is the opposite of 'static'.

get root,
write a script /etc/rc4.d/S50ipup.sh:


#
# (c) turbines 2004
#
ifconfig eth0 192.168.100.11 up

make it executable.

voila.

[turbines]

root@knopbox:~# /etc/rc4.d/S50ipup.sh:
bash: /etc/rc4.d/S50ipup.sh:: No such file or directory

[user unknown]

You shall not execute the file, but create it.
(later you may execute it).

But it's a good idea to test the command first:


ifconfig eth0 192.168.100.11 up

and if it works (no reply)


echo "ifconfig eth0 192.168.100.11 up" > /etc/rc4.d/S50ifup.sh
/etc/rc4.d/S50ifup.sh

[turbines]

Ok I found the key to the fix in this thread
http://www.knoppix.net/forum/viewtopic.php?p=19004

I reconfigured my router and disabled DHCP. Then I set up static IP address.

# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
# automatically added when upgrading
auto lo eth0

iface eth0 inet static
address 192.168.100.11
netmask 255.255.255.0
network 192.168.100.0
broadcast 192.168.100.11
gateway 192.168.100.10

Then I edited /etc/init.d/knoppix-autoconfig
and replaced

pump -i $DEVICE >/dev/null 2>&1 &

with

/etc/init.d/networking restart

Now I have connection after every restart

Thanks for the help

[user unknown]

set the broadcast adress to 192.168.100.255 and I'm happy. :)

(and welcome to the wonderful world of static IPs :) )

[turbines]

Done!

Thanks again
