**hicks** · 12-16-2003, 04:47 AM

i'm a linux newbie. i downloaded the 3.3v of knoppix live cd and i can't seem to get the network to work. my netcard is recognized, i run netcardconfig but i can't get on the network. the network connects to the internet. i get the ip, subnet, gateway, dns, everything. same thing works on suse and mandrake live cds. i need help. what can i do?

Networking 101:

Can you ping by i.p.?

ping 66.218.71.198

If so can you ping yahoo.com

ping www.yahoo.com

You can try to restart the network interface like so:

sudo /etc/init.d/networking restart

You can also run pump:

pump

What kind of NIC?

I am also looking to use the live knoppix to connect to my lan. I have a windows 2003 server, and would love to use the live knoppix as a client boot disk.

It states that "lisa" (Linux Internet Server Administration) is not running because with the live knoppix you don't get root access. which you need to get it started.

So- how do I start lisa with the live knoppix? Or, do I need to set up knoppix on a hard drive, install all the drivers, settings, and programs I want for the client machine, then burn it to a bootable iso cd rom?

Well, once I learn how, I post back!

Hi Jeremy,

...because with the live knoppix you don't get root access...

In a Konsole (the screen with the seashell) type "sudo su" to become root. Or change to VT1..4 with <ALT><CTRL><F1>..<F4>, there you are root, back to KDE with <ALT><CTRL><F5>.

Ciao Martin

well i'm new to linux, not that new to networks

no, i cannot ping to ips or urls. i cannot even ping my gateway (which is at my isp's). it all works fine with windows, suse 9.0 demo and mandrake move (both live cds).
my netcard is d-link dfe-530tx.

What does lsmod in a console window (clam shell icon on the taskbar) tell you you should see 8139too listed with a 1 beside it at least that is what is uses for my card but it is a tx+. You can try mii-tool -r to restart the card autonegotiation and then do netcardconfig to configure the card.

Try adding thefollowing to the end of /etc/init.d/networking:

echo 0 > /proc/sys/net/ipv4/conf/cm0/rp_filter

Let me know if that helps...

nothing really helped. but, i thought to give it another try so i loaded knoppix and as usuall just tried to setup the network (netcardconfig, nothing special) and for some strange reason it actually worked. i have no idea why since i've been trying the same thing for a while now. go figure. so this time i saved the settings and now it works every time i boot knoppix.
i only wish i knew how or why.
thanks for all the help though.
