Can't make My LAN connection working

[Axe]

Please Help me! I've Realtek 8139 LAN card installed on my Mother Board. Though Knoppix detects the Ethernet card but i'm unable to find any way to configure it, i thought it would be as easy as it's with MS Windows, but i don't know how to get it working. The few things that i know(or are required by Windows at least) are The IP address, Subnet mask, Default Gateway, Host/Domain, DNS Server, besides i donno anything about Linux....please help me :( !

Open a console window (clam shell icon on the taskbar) and type in netcardconfig decline the DHCP then enter the settings required you have all the information you need. If this fails then could you post the output of lsmod, ifconfig -a and maybe lspci -v from the console window just type them in and enter. To get a file you can save to a floppy and use to post from you other OS add > file.txt to the commands eg. lsmod > lsmod.txt this will save the output of the lsmod command to the file lsmod.txt in the current directory which would be /ramdisk/home/knoppix then copy it to the floppy to post it. You may want to post the lsmod command twice both a copy before the netcardconfig and after so we can see if the module for the card is loaded and in use before the command is issued.


Also do you use static direct connection or PPPoE to connect?

Sorry for replying late.
I tried the Netcardconfig, but still i'm unable to configure the card/connection. Below is the output of the commands: "lsmod", "ifconfig -a ", "lspci -v", it still seems that the results are negative.

You are using an i instead of l (L) for the command.


knoppix@ttyp0[knoppix]$ ifconfig -a

Here it sees the card but it has no IP address.

Here again you are using i instead of l (L).

It looks like the module (IIRC it is the 8139too module) for the card is not loaded you may want to try from a console window sudo insmod 8139too to load the module and then netcardconfig to configure the card. note: I have seen a lot of post with people having problems with the onboard realtek NIC's you may want to disable it and put a card in an open slot if you have one.

Here's the output of the Lsmod, Ifconfig -a and Lspci -v command, and u were right, i was using I instead of L.

I do not have on-board LAN, rather it's a seperate card, MSWindows shows it as Ethernet 01, whereas Knoppix detectes it on Ethernet 0.

One more thing that i'd like to know's that, how can i log-in as root? cause i've created persistent home on my HD, but whenever i try to open it from home, it says that u do not have enough privilege to access it, that u must be logged-in as root.

Please help me. i'm hanging in here :(

The module is getting loaded but not used also the mii tool is being used have you used it to try and set the card or is knoppix using it?

Here you have three devices using the same IRQ this could be the problem is there any way that you can change the IRQ's being used in your BIOS or on the card itself?




I do not have on-board LAN, rather it's a seperate card, MSWindows shows it as Ethernet 01, whereas Knoppix detectes it on Ethernet 0.


This is normal linux usually starts naming devices with 0 instead of 1 and with this being an card instead of onboard NIC you may want to change the slot it is in this could get you a different IRQ for the card when it is detected on boot.


One more thing that i'd like to know's that, how can i log-in as root? cause i've created persistent home on my HD, but whenever i try to open it from home, it says that u do not have enough privilege to access it, that u must be logged-in as root.

I have never used the persistent home but to become root with any command you want to issue you use the sudo in front of the command you may want to start a new thread for this problem.

You may want to try using some cheat codes (http://www.knoppix.net/docs/index.php/CheatCodes) when you get to the boot: prompt like knoppix nousb or maybe noapic to see if that will help with the network card being used.

Another thing you can try is entering your settings manually in the required files and re-starting the networking that way.

The file /etc/network/interfaces is where your settings for the card are contained example file below:

For Static settings


# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
auto lo
iface lo inet loopback

# The first network card - this entry was created during the Debian installation
# (network, broadcast and gateway are optional)
auto eth0
iface eth0 inet static
address 192.168.0.1
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
gateway 192.168.0.254


You would of course use your settings to edit the file open a console window and sudo gvim /etc/network/interfaces may the changes and save the file.

Your nameservers settings would be in the file /etc/resolv.conf example file:




search wolf
nameserver 192.168.1.10
nameserver 192.168.1.34


You only need the one nameserver line the search of your domain and the extra nameserver are not necessary. Edit the file put in the correct settings and save it then sudo /etc/init.d/networking restart to re-start the network with the new settings. Post the output of any errors that you get so I can see what they say.
