Problems Configuring Networking
 
I just installed my first linux distribution, Knoppix 3.4. When using the livecd, Knoppix detected and autoconfigured my network interface (eth0) using DHCP. However, now that I have installed Knoppix on my hard drive, it doesn't seem to recognize or configure the device properly, and I cannot connect to the internet.

I'm new to linux and I don't even know where to start. If someone could tell me how to fix this problem, or at least point me in the right direction, I would appreciate it.

Thanks,
rtwatts07

rtwatts07,

Congrats on the install, welcome to the wonderful world of Linux!

If you do an "ifconfig eth0" what is your output? I don't know Knoppix all that well, but I imagine your card is in the kernel by default and just needs to be loaded as a module. You can try booting back into the knoppix livecd and recording the output of "lsmod", then comparing that to what you get when you boot into the installation you just performed.

Does that help any?

I would really appreciate any help on this problem.

Thanks,

Anybody know what the problem is? Should I try to load all the kernel modules specified in livecd Knoppix? Are there other tests I should do? I guess the real question is: Why isn't this all done for me with dhcp?

Any help/suggestions are appreciated!

Thanks,

Normally with Knoppix you have to configure the ethernet card to get it working off the main menu but I cannot remember the exact steps. It is Debian based so the networking will be controlled through /etc/network/interfaces. If you have dhcp installed then edit the /etc/network/interfaces;

auto eth0
iface eth0 inet dhcp

then do /etc/init.d/networking start and check with ifconfig . The entry in /etc/network/interfaces will ensure networking starts on boot.

Hope this helps.

try dhcpcd eth0 from terminal as root.
then ping www.google.com -c 3
