Debian DHCP problem?

Hi,

I cant get my new debian install to get an ip address from my router
via dchp. I have booted into knoppix on the same machine and it works
fine, there is something I must not have configured correctly in
debian.

The card has the same irq and address in knoppix and debian. In both
the irq (10) is shared with other devices. I cant see any errors in
dmesg. In debian eth0 doesnt receive any packets at all.

In debian /etc/network/interfaces reads

auto eth0
iface eth0 inet dhcp

There is nothing about eth0 in this file in knoppix.

Any pointers on how to fix this debian, or on where the configuration
for the network cards is in knoppix would be appreciated.

Thanks
Chris

what happens if you type 'dhclient' at the prompt?

It just sits there and freezes.

Thanks for any help

No it doesn't - it times out and backgrounds itself after about 2
minutes. It's supposed to sit there first, pinging away. Anyway, the
command is

dhclient eth0

not "dhclient" (which will ping even on localhost!).

What happens if you look in the man page for dhclient and avail
yourself of the debugging facilities listed there?

What happens if you look at the interfaces you have up and tell us
about them?

Hi,

Thanks for the reply.


This is the output I get when I try to bring up the SMC card.

The output when I bring up my other network card is below.

How do you "try"? And what has that to do with dhcp? This is the output
from what? And output from where?

Why are you asking for dhcp on eth1? Why not eth0?

Well, that's all fine. Nobody is listening there. Tcpdump -i eth1 would
show you. Mind you I'd set the interface to up and a local net address
before launching dhclient eth1 (you don't say if that is what you did!).
Some servers don't like it otherwise.

What do you mean by "bring up"? What do you do? Where and what is this output
from? Please give all necessary data!

That makes it look as though you are running some weird compound
command. What?

Well that's fine. Make it executable if you care. But you are running a
weird dhclient anyway. dhcp3 is not the place for it.

% dpkg -l dhcp-client

and the listing contains nothing in dhcp3.

Well change it so it is then. If you care.

Well, that's clear. That network has a server replying fine on it.

FIne.

What's your problem? There's no response on the eth1 network. As you
can check with tcpdump -i eth1.
