Network Problem with dhcp

[Rakim]

Hi,

i userd the search Option quite a bit but couldnt find anything that helped me.

I have a Window's Computer that is hooked up to the Internet an has a Routing programm running on it.

My second computer uses DHCP to get an IP Adress from the Routing Programm. When i run Window's everything works joust fine.
I then used Knoppix booted from CD and everything worked fine as well.
Then i installed Knoppix to my Harddrive and everything worked no problem.
The next day i booted the machine and could not hook up with the Internet..
So i booted into Windows on that machine and everything worked.

Now when i use :

netcardconfig as root it tries to obtain an ip adress an return with :

Operation failed

Anybody out there that can help ?

Tanks in advance

Try

/etc/init.d/networking restart

Then do

ifconfig -a

and see if you have an i.p. address. If you do have an ip then try to ping.

Thanks for the Answer

Like i said i get an operation failed and it doesent recieve an ip Adress.

Dhcp must be working correctly (at least for Window's) since when i boot Window's on that same machine everything works fine ....

If i set it to static the ip adress is applied and i can ping it. But it wont let me ping my other Computer

I assume you mean you can ping the static IP address you assigned to the problematic machine, but cannot ping anything else on your LAN. Pinging your own IP doesn't actually transmit any bits "on the wire" (its like pinging the loopback address). This sounds like a problem "talking" to the NIC hardware - is the IRQ in knoppix the same as in windows and are there any error messages in the system log?

Good luck

again thanks for the Answer

I joust treid the ping to see if the adress was apllied.

Only Error Message that i can find ist the "Operation failed" .....

Now yesterday i tried the Networkconfig Programm agian and everything was working again. After another reboot i had the same problem i described in my first Post.

Got no clue whats goin on

I have almost this exact same problem, only mine quit working completely. Even after several reboots my network cannot find an ip address. It even shows the network card as being installed, but the light just blinks. Works fine in windows too. it sucks.. please let me know if you find anything out Rakim
thanks

Have those of you with this problem tried sudo mii-tool -r and then netcardconfig? What are the results if you do?

[stupidkid]

when i run sudo mii-tool -r, i guess this could be the problem right here

SIOCGMIIPHY on 'eth0' failed: Operation not supported no MII interfaces found

netcardconfig of course failed also..

May not be hopeless yet, I don't know what makes a NIC qualify as MII. Try this and see if it helps: boot, when you get to the Knoppix prompt boot in expert mode, then answer n to all qusetions. While my nic will not boot properly any longer, the mii-tool reset or this trick will let it work. No promises but worth a try.

After a few hours of messing with ifconfig I stumbled uppon this and it worked perfectly for me.

It just came up with a prompt for Dhcp enalble, I clicked yes, and it retrieved my dynamic ip etc and I was off and running.

Thanks!
