I have just started using linux,i have window xp
and knoppix 5.0 on my system.I am a school boy so for connecting to internet i have to connrct to the school server but i am able to connect to school server through windows but not through linux(knoppix 5.0).
There is also one interesting case as i am boot linux(knoppix 5.0)through live cd i am able to connect to server and able to use internet.
please tell how i would connect to internet through knoppix hd installed.ip address is 192.168.255.173
Thank you for Replies

Have you checked your network config? Most likely, the gateway isn't properly configured or something like that.

Did you do anything to configure your network card while booting Knoppix from CD?
If you didn't, then my guess is that you need to setup DHCP client rather than using a fixed IP address.

Please post the output of "ifconfig" and the details of the network config (gateway IP, subnet mask, ...). These config details can be found when you run ifconfig after booting the Knoppix CD or by executing "ipconfig /all" after booting Windows.

In:

/etc/network/interfaces

Make an entry like this:

# The primary network interface
allow-hotplug eth0
iface eth0 inet 192.168.255.173

Here is output of ipconfig/all & ifconfig

i have not done any network configuration when boot from knoppix live cd
Thankyou alok

As I guessed, you'll need to use DHCP to obtain an IP address and other network settings.
This is done in the Windows configuration as well:
So boot your Knoppix (installed on hd), then select your network configuration from your panel (or run "system-config-network" tool from commandline). It'll show you your active network cards, edit eth0's settings and make sure that the option to use DHCP to automatically obtain an IP address is enabled.

Report back if you can't make this work.

thanks for reply, but none of your alternatives are working.
1) i am not able to find network configuration in my panel, because i just 2 to 3 times opened knoppix desktop.

2)when i type command "system-config-network " i got error "command not found". I also tried command "netconfig" & "service network restart" but again i got same error.
will you please tell me where i was wrong, As i am able to connect to internet through live cd of Knoppix;
Thanks again for reply

Like I told you, your system needs to be configured to use DHCP (client) to get an IP address from the network's DHCP server. This IP address can then be temporarily used by your system (ie until the leased IP expires or until you reboot your machine, at which time the DHCP client will ask for another IP).

system-config-network is in /usr/bin on my Fedora box. It can be called differently or reside in another directory in Knoppix.

In general, I just wanted you to use the graphical interface to your network card config, rather than editing the settings directly in /etc/ files or /proc files. In the panel, it should be under "System Settings" or "KNOPPIX menu -> Network/Internet -> Network card configuration" or something like that.

I have problems to conect to the internet, i have just instaled opensuse 10.2 and I skiped the internet connection part, and now I am not able to configure the conenection (or network card). I have Realtek PHY RTL8201CL LAN card and I am connected to the internet through sweech. What should I do to connect?

@latifovich: you should start by reading the forum rules, which clearly say that you shouldn't "hijack" other people's posts. That said, I would recommend that you:
-insert the installation CDs and install the network stuff you skipped before;
-try to configure your network card via the tools that are installed;
-give us some details (IP addresses, subnet mask, the IP address of your switch, etc), so that we can help you set up your machine. But please post these details on a new thread (that you create), rather than this thread.
I suggest that you start this new thread on either the hardware forum or the newbie forum.
-You could also search these forums (or via Google) to see if anyone has overcome a similar situation like you.
