[gelöst]openSuSE 11.2 - Routing funktioniert nicht

S

sandhase2001

Hallo,

ich habe folgendes Problem mit meinem Linux-Rechner, der im internen Netz als Server und Router zum Internet fungiert:

Die angeschlossenen Windows-Rechner im internen Netz (eth1) können nicht per PING erreicht werden und folglich auch keine Verbindung zum Internet herstellen. Der Linux-Rechner selber kann über eth0 eine Verbindung zum Internet herstellen. Der Internetzugang selbst wird durch eine Fritz!Box aufgebaut, mit welcher der Linux-Rechner über eth0 verbunden ist.

In den Netzwerkeinstellungen habe ich IP Forwarding aktiviert. Ebenfalls ist in der Firewall Masquerading aktiviert. Dies sind die Einträge der Routing-Tabelle:
Kernel IP routing table
Code: 
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.178.0   0.0.0.0         255.255.255.0   U     0      0        0 eth0
192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        0 eth1
169.254.0.0     0.0.0.0         255.255.0.0     U     0      0        0 eth0
127.0.0.0       0.0.0.0         255.0.0.0       U     0      0        0 lo
0.0.0.0         192.168.178.1   0.0.0.0         UG    0      0        0 eth0

In der Firewall habe ich bei Masquerading keine Einträge hinterlegt. Muss hier noch etwas eingetragen werden?
Woran kann es liegen, dass ich keinen PING in das interne Netz schicken kann und der Linux-Rechner nicht per PING erreichbar ist?

Ich hoffe, mir kann jemand einen Tipp geben, was ich noch prüfen / einstellen kann.
Vielen Dank dafür schon einmal!

Rufe mal das Script mit den Parametern
Code: 
./collectNWData.sh -frlc
als root auf und poste dann den Inhal der im selben Verzeichnis erstellten Datei collectNWData.txt.
 
Hallo,

hier der Inhalt des Scripts:

Code: 
collectNWData.sh V0.6.3.2 (Rev: 1.205, Build: 2010/03/13 15:50:37 UTC)
--- Which type of your network connection should be tested?
--- (1) Wired connection
--- What's the type of networktopology?
--- (3) DSL modem <---> LinuxRouter <---> LinuxClient
--- On which host is the script executed?
--- (2) LinuxRouter

--- NWEliza is analyzing the system for common network configuration errors ...

!!! CND0310W: Classic network configuration with ifup was detected. Configuration with knetworkmanager is much easier

--- Go to http://www.linux-tips-and-tricks.de/CND#English to get more detailed instructions 
--- about the error/warning messages and how to fix the problems on your own.

--- If you are unsuccessful then place the contents of file collectNWData.txt in the net
--- (see http://www.linux-tips-and-tricks.de/CND_UPL#English for links) 
--- and then paste the nopaste link on your favorite Linux forum.

Es sieht alles soweit Ok aus (Die FW muss aktiv sein - ist sie zum Zeitpunkt des Scriptlaufs nicht gewesen). Benutzt Du die IP Adresse oder einen Namen? Teste mal mit der IP Adresse ein ping.
Code: 
ping 195.135.220.3
Das ist die IP von http://www.suse.de

U.U. ist was mit dem DNS Setup nicht Ok.

Nur um sicherzugehen: Vielleicht kannst Du das Script auch noch mal starten wenn die FW an ist und die Ausgabe posten.
 
Vom SuSE-Rechner funktioniert der Ping ins Internet ohne weiteres. Aber aus dem internen Netz (192.168.1.0/24) kann ich keinen Ping absetzen. Weder vom Windows-Client erreiche ich den Linux-Rechner noch vom Linux-Rechner einen Windows-Client.

Hier nochmal das Script:

Zwei Dinge:

1) Du hast noch nicht gesagt ob der Ping mit der IP Adresse failed und/oder der Ping mit einem Netzwerknamen ;)
2)

Das hat sich auch schon oft als Bremser herausgestellt. Disable das doch mal.
 
Mal eine blöde Frage:

hast Du in der FritzBox auch hinterlegt (Route eingetragen), dass er Deinen
Linux-Rechner (Router) benutzen soll, um mit Deinem Client zu kommunizieren?

Wenn dem nicht so ist, dann weiß die FritzBox nicht, wohin sie denn die
Pakete zurück zu Deinem Client schicken soll.

Bis denn,

Weder vom Windows-Client erreiche ich den Linux-Rechner noch vom Linux-Rechner einen Windows-Client.

Ist Dein Verbindungskabel an eth1 OK? Benutze testweise mal ein anderes. Oder hast Du aus Versehen ein CrossoverKabel benutzt?

Vielen Dank für eure Hilfe!!
