New to linux, cannot connect to the internet.
 

I'm using the knoppix 3.7 livecd. I put it in, and it went wondrefully - detected everything, and looked like it was going to work quite well. Everything does, except that it won't connect to the internet. I used ifconfig, and eth0 doesn't show up, but eth1 does and has an ip address. I'm guessing that eth0 is my wireless adapter, which I have disabled, and eth1 is my wired adapter, which I would like to use. What do I need to do?

try assigning ip address to ur eth0

ifconfig eth0 <ipaddress/subnet>

regards

The message I get when trying that is:

SIOCSIFADDR: Permission Denied
SIOCSIFFLAG: Permission Denied

Any other ideas?

before that

yes u need to run

su

before that,knoppix by defaults does not give u all the permissions

regards

Okay, I did that, and now eth0 shows up in ifconfig with the ip address, but I'm quite sure that eth0 is still the wrong adapter, and that adapter isn't connected to anything. I still can't connect to the internet, as well.

post the O/P of

ifconfig

and

route -n

ifconfig:

And for route -n(the table won't fit, so I'll just list the order of the columns):
Kernel IP routing table
Destination, Gateway, Genmask, Flags, Metric, Ref, Use, Iface

24.244.xx.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1


24.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 eth0


0.0.0.0 24.244.xx.1 0.0.0.0 UG 0 0 0 eth1


I hope I didn't make any typos...but that looks to be it.

so u see ur default route,it is through eth1,now can u ping

24.244.xx.1

also what do u get for

traceroute yahoo.com

Traceroute: unknown host yahoo.com

what is ur gateway and dns server address???

try

route del default

then

route add default gw <ip addr of ur gateway>

regards

I just checked, and it has the correct address for my gateway.

I entered those commands in anyway, and it didn't change anything...

Is it okay that the destination address for eth1 in the routing table has a 0 in the fouth octet?

24.244.xx.0

yes thats is fine

can u ping ur gateway?

No, I can't.
