Hi,

a)I've installed Linux Enterprize(ws) on my pc.

b)I've configured /etc/sysconfig/network-scripts/ifcfg- eth2.

c)I've also configured /etc/sysconfig/networking/devices/ifcfg-eth2.route.

d)I've configured /etc/resolve.conf.

e)I can ping my gateway.

But It cann't open any URL.

what about default gateway?
is it set to the ip of the remote system on the other side of the broadband modem?
[ or to your router's ip ]
is the default network interface really eth2? it is usually eth0
your isp is most likely using dhcp, your nic config has to invoke dhcp to get an ip number.
[ unless you are paying extra to get a static ip from them. ]

I was actually pleasantly suprised when I read your question, most people seem to think they have to configure the modem itself not the network card, so you are leaps and bounds ahead of the game

Check your name resolution with the dig command. You should get a return like below:

Code:

The part that you are looking for is on line 4 where it says NOERROR. If you get NXDOMAIN then either you are not resolving or not getting past your gateway. To check if you are getting past the gateway try pinging one of the public address above associated with ns?.linuxquestions.org.

A broadband modem may need to be provisioned before you can use it. If it is connected to a new device ( with a new MAC address ) the process needs to be repeated. Usually this can by done by pointing your browser to your modem, or the url of your ISP.

Is this a cable modem or a dsl modem. Being that you didn't mention ppoe, I assume it's a cable modem.

You stated the items you configured. You might want to post the contents of /etc/resolv.conf and the route command so we can verify that your configurations were correct. Also the output of ifconfig would be helpful. The "eth2" item begs the question on what eth0 and eth1 are used for.
