Something wrong with internet or configuration in SuSE 9.0..


HI,

so here I am, having installed SuSE 9.0 and unable to connect to the internet. I use to connect through LAN. I've configured the network card, specified needed IP, gateway.
I used 'traceroute' in console, and that's what I saw:

1. 172.16.136.254
2. 172.16.4.254
3. 10.0.2.7
4. *
5. *
6. *

and all the way down. So i guess the packets get through gateway, router, and then the path isn't known.
The same stuff is in Windows, but somehow I get to internet there..

So, can you recommend what to do? Maybe everything with the conection is ok and I just need so enter smth somewhere else?

Thank You

The asterisks symbolises timeout. The next host didnät answer within a sertain time, couldnät be reached. This could be due to a crashed server or router but it could also be a firewall block that kind of trafic along the way.
Internet could still be working despite this result.
I canät tell why you canät surf the web, as this result indicates that your box are able to reach at least a few hops towards the destination.

Hmm, asterics have gone now.. i can see every point that packet goes through.
But now, is there something to be done in order to show that f.e. Konqueror browser must use LAN connection to get to the internet, instead of any dial-up ir smth?

plees, advise smth

No all programs go about the same way when tey try to connect to another host, local or remote.
The first things I try when tracking network errors is to see if I can surf websites on IP directly, if that works then the problem usually is with the DNS.
Either the DNS settings are missing/misconfigured or the DNS servers are out of service/overloaded.

Are you connecting through a firewall device, and do you need to add the Linux PC to that device configuration?

If you are using a proxy, have you entered the proxy settings, and login / password if required? Did you confirm them in your browser?

Can you ping the linux box from another PC?

I am a novice, but these questions occurred to me. Lastly, if you just finished the installation, have you rebooted the SuSE box yet?

Thanks ima, i'll consider suggestions.

Now ugge, can you give just a simple clue how/where are the DNS servers configured on linux?

In /etc/resolv.conf something like:
nameserver ip.of.the.dns

Fire up YaST (found under system on startmenu).
Select network Devices and then Network Card.
It will auotodetect your NIC and it will aperaer in the lower half of the window.
Click the Change... button
Select eth0 and click Edit
Klick Hostname and names server configuration.

On my setup, I entered a static IP that the firewall assigned, along with the correct netmask. (DHCP did not seem to want to work properly with my SMC barricade.)

For the nameserver I entered the IP of the firewall device, and for the domain I entered the name of my workgroup. I also entered the IP of the Firewall device for the Gateway. It worked fine for me.

I verified first by pinging the firewall device. If you are connecting through a windows machine, you will need to setup your SMB sharing.

Unless I am completely off base, which, as a newbie, is completely possible. But again, this is what is working for me.

Nameserver == DNS server. Your firewall device is unlikely to also provide DNS services unless it's a gateway PC itself. In most cases your DNS servers would be something your ISP could advise you of, (some ISPs insist that you use DHCP for this though so they can change the location of their DNS servers as their infrastructure grows and changes without affecting their users too much.) In almost every case you'll need a DNS server that's external to your own personal network.
