Cannot seem to get ethernet card working. Help!!

MikeyS · 08-12-2005, 05:49 AM

Hi - Wondered if anyone might be able to help?
I've just got hold of an old machine, which I decided to use for learning Linux. I put in the ethernet card (netgear something or other - not sure on the model) and an extra hard drive. I burnt the Debian 3.1 net inst cd and off I went. It seems that the machine couldn't communicate with any of the download mirrors, so I decided to install the base system, which was fine.

Now, logged into debian3.1 (Kernel 2.6) as root, I can ping my loopback interface, and my own IP address. I cannot ping the router or any of the other machines (windows) on my network.I have verified IP settings are all correct, and now, to be honest, I'm stuck.

I'm knowledgeable in windows, and so I understand most technical issues, however, when it comes to Linux, well, I'm here to learn!

What steps should I take next? Is it true to say that since the machine can ping itself then the NICs drivers are correctly installed?

It's not easy for me to take screenshots fromt he Linux box, since the ethernet card isn't working :-) but if anyone can think of anything obvious, or of the next steps I should take, I'd be grateful.

Thanks,
Mike

Mike,
Can you post what ifconfig tells you as well as route?

Drivers's are installed in your case ,that's why it is showing self ping, but some problem in your card pins(where we putting rj45 jacks) or network cable.Did you try this same network card and cable in some other working computer.Let me know your status

Might also pay to check

Code:

/etc/resolv.conf

which is where your dns IP's are, should look something like this

Code:

nameserver xxx.xxx.xxx.xxx
nameserver xxx.xxx.xxx.xxx

and welcome to LQ

ifconfig shows a valid MAC addr, correct IP addr, bcast addr and subnet mask.

the next line says:
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

All values set to 0 - no rx packets, nno tx packets (except for 5 tx errors), txqueuelen 1000
Interrupt 9, Base address:0x2000

Route gives:

0.0.0.0 * 255.255.255.0 U 0 0 0 eth0
default 192.168.0.1 0.0.0.0 UG 0 0 0 eth0

Thanks,
Mike

Looks like DNS server is set correctly (to the router, which forwards all DNS requests).
Thanks,
Mike

No, i haven't tried the card in another machine - however, the link light is there on the hub that it's plugged into. Also, mii-tool reports that a physical link is there.

Thanks,

Try adding a routing table entry to your router. If the router is 192.168.2.1, then add it with this command (just substitute the IP address of your router):

route add 192.168.2.1 eth0

Then try to ping the router again.
