Network card installed, but no internet connection

[SnagaDuath]

Hello!

I'm new to linux and i just installed suse 10.2. During the installation it automatically picked up my onboard network card, so i entered my ip and a default gatway to my router, but it could not download the latest release notes. So i skipped that and finished the installation.
Now when i run firefox i can log onto my router by typing it's ip into the address bar, but i do not have an internet connection.

It works fine on all other computers on the network and on my own when i run windows.

Any ideas?

Thx
SnagaDuath

Are you getting an 'unknown host' error?

If so, check /etc/resolv.conf for a line to the effect of

nameserver <gateway IP>

If that isn't the error, ping google and post the error here.

Let us know how you get on,

The resolv.conf file contains only one line : "domain Domain"
When i ping google i get the unknown host error you talked about.

[kakariko81280]

Easy then (someone please note use of Famous Last Words), put in the nameserver line on a line by itself, being sure to change the bit in <> to the actual IP address of your gateway. You'll need to be root to edit the file.

Try pinging again and let us know how you get on,

I changed th resolv file to:

nameserver 192.168.1.1

now i get 'network unreachable' when i ping goolge.

I noticed that when i enable dhcp on my router and configure my network card accordingly everything works fine and the resolv file contains this exact line, but the moment dhcp is turned off i can only access the router.

thx for taking the time to help me!

Yes, dhcp will configure all of these things for you, but it might be valuable for you to fix this without dhcp just so you can see what's involved.

Can I get you to run the following commands (using the static settings you have so far) as root.

ifconfig
route -n
cat /etc/resolv.conf

I would very much like to have it configured using static settings, i'm just happy that i don't have to reboot to windows every 10min anymore

this is the output for the commands:

It looks like your missing the default gateway entry in your routing table:

route add default gw 192.168.1.1

Should fix it up temporarily. If this works, let us know and we can look at making it permanent. Otherwise, post the errors you get.

It works now!

I'm a bit baffeled, though....i'm sure i entered the default gateway in the configuration during the installation

Anyway...thx a lot for your help!!

[kakariko81280]

Check this thread for a quick discussion on making default gateways permanent under suse.

Let us know how you get on,
