I have managed to install the driver for my NIC card
(Broadcom 440 ) for RH Linux 9 on Dell inspiron
now in network device manager I see:

Status Device Nickname Type
Active eth0 eth0 Ethernet

I have cable connection to Internet.
However with Mozilla I am not able to surf the Internet
Why is it so?


I have set up Internet connection with internet connection wizard
and chose the option
Automatically obtain IP address setting with dhcp

so the ethernet device is configured with
Automatically obtain DNS information from provider

and the device is active

with my connection I'm required to have:

100Mbit network card
cat5 cable
and set the option 'obtain an IP address automatically'

under windows it works fine
but under linux although my card is active
I can not ping any IP address

Here what I have:

[root@localhost root]# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0

What does ifconfig eth0 show?

Here it is:


[root@localhost root]# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:0BB:95:23:5A

Do you have a names server running?

[root@localhost root]# cat /etc/resolv.conf
search localdomain
nameserver 127.0.0.1

You have no names server listed. Just add your ISP's DNS server in your /etc/resolv.conf.

Could you please explain what is nameserver
and which line exactly should be added to /etc/resolv.conf. [/B]

My ethernet device is configured to
automatically obtain DNS information
so I was expecting I have done enough
At least under Windows it is like this working fine

Thanks!

Dunno why its not automatically finding your dns, but what you need to do is, go into windows and find out what your dns addresses are, or contact your isp. There should be two dns or nameservers. One is primary the other is secondary. Write them down and boot back into linux and open your /etc/resolve.conf file with a text editor and add the addresses.
nameserver xxx.xxx.xxx.xxx
nameserver xxx.xxx.xxx.xxx
You might have to restart your card
ifconfig eth0 down
ifconfig eth0 up
and you should be good to go.
You could get it to auto find it by adding some stuff to another file. Open up /etc/network/interfaces with a text editor. Add the following lines

# The primary network interface
auto eth0
iface eth0 inet dhcp

That should bring up your card when your machine boots and set it up for dhcp.

I added nameserver so now /etc/resolv.conf :

search localdomain
nameserver 127.0.0.1
nameserver 145.97.192.38
nameserver 131.211.4.5

And I still cannot get to Internet from Linux

I did that, here is the /etc/resolv.conf

search localdomain
nameserver 127.0.0.1
nameserver 145.97.192.38
nameserver 131.211.4.5


however Internet is still not working

concerning the /etc/network/interfaces I did not find this file It doesn't exist

By change, can you ping those IP addresses?

when I ping some address then it says nothing for a long time and I close the terminal

I dont think you want that 127.0.0.1 line in there. In my resolve.conf all I have is two nameserver lines with my isp's dns machines adresses, under that is search. ie
nameserver 203.194.27.57
nameserver 203.194.56.150
search
If you have the 127.0.0.1 line, it will use your machine to resolve the adresses which it cant do. afaik.
Ring your isp and find out the numbers of there dns machines and only put those two in there and see how you go, if not post back.
What distro are you using.
If the above didnt work, can you post the contents of your
/etc/sysconfig/network file

I have done that ...it is still not working

here is /erc/sysconfig/network

NETWORKING=yes
HOSTNAME=localhost.localdomain

The only thing that I can think of is that you default gateway(your router's IP) is not set. That is where your PC looks when that address is not local. Try setting up the nic with a static IP.

I have tried already so many advices...and have done so many different reinstallation..
so the hope to make it working was vanishing
But now I'm happy!!!! do u believe? I'm typing this from Linux!!! Yeaaah!!!
Actually I set NIC card with static IP, subnetmask and default gateway
Why It was not able to do so automatically with DHCP I don't undertand


THANKS A LOT LINUX-FRIENDS!!!
