Thema: (Gelöst)Probleme Suse 10.2 über LAN->Router->DSL

Hallo,

mein erster Beitrag hier, also grüsse ich alle herzlich.

Ich bin totaler Linux-Newbee und habe mir diese Woche
openSUSE 10.2 draufgezogen. Desweiteren habe ich WinXP prof drauf.

Leider komme ich nicht ins Internet. Ich gehe per LAN in einen Zyxel-DSL-Router.
Diesen kann ich auch erfolgreich anpingen und das Config-Programm im Browser
aufrufen. Mit dem Router selbst kann ich auch ins www pingen.
DHCP ist ausgeschaltet, der Netzwerkkarte die feste IP sowie Gateway zugeordnet.

Das Skript von Framp ergibt folgendes:

Code:

Was kann ich tun?

Die IP des Routers als DNS-Server (Nameserver) eintragen.

Hi,

danke für die prompte Hlfe, hat sofort geklappt.

bombadil79

Und hier für (Querleser), woran man die Fehler in der Konfiguration eindeutig erkennen konnte (Vielleicht hilft es ja jemandem).

Ursache:

Code:

*** cat /etc/resolv.conf | grep -v "^#" | grep -v "^$"

Die Datei '/etc/resolv.conf' ist _leer_, es ist also kein DNS-Server (Nameserver) eingetragen.

Symptome:

Code:

*** ping -c1 -W 3 195.135.220.3 
PING 195.135.220.3 (195.135.220.3) 56(84) bytes of data.

*** ping -c1 -W 3 www.suse.de

Pingen einer externen IP funktioniert, pingen des selben Rechners über den Domainnamen funktioniert nicht.

=> DNS-Problem.

Da die meisten moderneren Router eine eingebaute DNS-Server Funktionalität haben, war der erste, logische Ratschlag, die IP des Routers als DNS-Eintrag zu verwenden.
