Hi everybody and thks for previous answers,
but i have a new problem,
i installed a Knoppix 3.4 Debian distrib, and i want to configure the network card to have an internet acces.
So i launch the wizard and put : (i have a router without firewall)
DHCP broadcast : nothing
IP adress : 10.0.0.100
Netmask : 255.0.0.0
Broadcast : nothing
adress Gateway : 10.0.0.138
Nameserver : plop

and it doesnt work, i dont understand, i put the same parameter on my mandrake, and it worked.
But on mandrake i put the DNS.And on the Debian they dont ask me the DNS adress.

Can anybody help me?i'm lost, thx

Most of the modems I have seen configure automatically under Linux (also under Windows, but with lots of problems). That means that the modem does the authentication and so on and then establishes the eth0 connection. User is connected to the Internet with no further interaction. Try doing 'ifconfig' and look what is going on. If you do not see a valid 'external' IP address (that is, no 127.0.0.1 neither 10.161.53.209 neither anyone in your LAN) you are having a problem. Using wizards frequently makes more problems.

DNS=nameserver, whatever you used with mandrake for the DNS put it where debian asks for nameserver; plop whatever that is will not work. If you do not know what your nameserver is ask either your admin or isp.

ok thank you very much odious, it was the probleme.
But now, i have another probleme.
I succeed to config the network card under KDE thanks to the wizard.
But know i want to configure it with the 'ifconfig' command line.
ip : 10.0.0.100
netmask : 255.0.0.0
gateway:10.0.0.138
DNS:213.36.80.1
so i know that it begin with : ifconfig eth0 10.0.0.100 netmask 255.0.0.0....
but i dont know the follow, especially how to include the nameserver(DNS)
if anyone know the perfect line, it will be great, thx again all.

I don't really know ifconfig. Try 'man ifconfig', as every app in Linux has their manual page, with very detailed information, probably in your language.

Anybody has another answer?
because i know the man page but i dont find how to put the DNS in the command line.
Thanks

Your nameserver and gateway really have nothing to do with ifconfig. Your gateway is set in your route tables via route add and nameserver in your resolv.conf file.

What are you trying to accomplish; are your loosing your settings when you reboot?

Tom

When i'm under KDE i don't loose my settings.
But i never succeed to set the parameter under Debian.
I don't try your advise because i'm not at home, but i'll try it later.Thanks a lot.

(offtopic) Debian and KDE are different things. You're probably running KDE over Debian, as KDE is a window manager and Debian is an operating system.

I know, but i said that i have two sessions, one with KDE and one with fluxbox, but both are under Debian.
And there are the same /etc/network/interfaces and /etc/resolv.conf files in KDE and fluxbox.But i have to reconfigure at each new boot.
When i use the wizard with KDE it works.But with fluxbox i don't success.
I don't understand why...
Thx

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

root@knopbox:~# ifconfig
eth0 Link encap:Ethernet HWaddr 00:E0:18F:B1:36
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

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;

root@knopbox:~# ifconfig
eth0 Link encap:Ethernet HWaddr 00:E0:18F:B1:36

When I reboot I have to point to the eth0 card again beefore I connect. How do I make save these settings to boot?

Thank you very much
