output of ifconfig

The first thing to check is whether the NIC device is detected and the module is loaded (using lsmod).

Your interface does not have an IP address assigned to it. Are you using DHCP? You may want to look in the output of the "dmesg" command or /var/log/messages for cues.
Also, what is printed if you run "rcnetwork restart".

Also, sometimes the quickest way to get things working is to first delete the interface in YaST, and then add it again, and configure it from scratch.

My networking works, but I can't resolve DNS names locally. Internet DNS works fine. On my company netork we have a MS 2003 server doing DNS and it won't feed my SUSE Linux machine, this worked fine in 9.3.

Looks like you might have the wrong DNS setting. Check these with your network admin at your workplace:


DNS server ip address
Default Gateway ip address
Is DHCP configured at your workplace? If so, you may just have to enable it on suse.

I'm picking all this up from DHCP, I am the network admin. I checked that I am picking up the right DNS. I can go to google.com just fine, but I can't ping our internal servers, bc3 for example does not resolve to anything.

run this command:

cat /etc/resolv.conf

and post the output.

I have same problem with SUSE. I have Toshiba satellite 1110 and I was amazing becouse in the installation SUSE detected my conection by wireless (linksys B wireless USB) but when I tried to connect by cable I wasn't able to do it. Usually the system has to detect automaticly. Somebody can sugest me what to do.
anuro

I'm having the same problem as Anuro, the system recognizes when i connect and disconnect my LAN cable (checked with dmesg) and it also assigns the proper IP (checked with route) but the OS won't let me use the f'ing device. Like when I open up KInternet and try to select an interface, only eth0 (my centrino wireless) shows up. A friend told me it had something to do with my routing tables, and I read elsewhere it might have to do with a loopback????

Same problem here too..
Ethernet card seems configured but Suse 10 from DHCP or static IP's cannot find host..Tried all the settings
I know and compared them to the same settings on suse 9.2 all agree but no internet..
I had no problem with this same setup on 9.2 or 9.3?? Something Wierd going on..

jolphil what kind of ethernet controller is it? not a realtek by any chance? if so i think i have your solution

Hi batorma

I have a realtek 8139 card. Will that cause any problems? I am thinking of an upgrade to SUSE 10.0

Well, in my case, I upgraded from suse 9.3 (in which my ethernet worked just fine OOTB) to 10.0. In 10.0 YaST saw the card just fine, it just refused to use it was all. I had to change the default module for it (8139cp) to 8139too in YaST > Network Devices > Realtek 8139 > Edit > Advanced > Hardware Details > Module. Then i restarted and it's worked just fine ever since. I've heard that the reverse is true for some people as well, 8139cp will work fine and too won't, go figure.

On the plus side, 10.0 did support my intel and d-link wireless controllers from my very first boot, that was impressive. I'd definetly give strong consideration to upgrading!
