BeitragVerfasst am: 24. Dez 2001 22:23   Titel: [SuSE 7.3] Absturz bei Internetverbindungsaufbau

Fröhliche Weihnachten

ich benutze SuSE/Linux 7.3 (Filesystem: ext3) ohne weitere Updates (Linux router 2.4.10-4GB #1 Tue Sep 25 12:33:54 GMT 2001 i586 unknown)

Der Linux Rechner übernimmt insbesondere das Internet-Sharing (T-DSL) inkl. Firewall (SuSEfirewall2).
Die Internetverbindung wird über einen Aufruf von "cinternet -start" bzw. "cinternet -stop" mit Hilfe von SSH per Remote auf-/abgebaut.
Teilweise kommt es vor, dass bei einem Verbindungsaufbau (seltener bei einem Verbindungsabbau) mit "cinternet" der Rechner sich einfach aufhängt und nicht mehr über das Netzwerk erreichbar ist. Da der Linux Rechner nicht gerade im selben Raum wie die Windows Rechner aufgebaut ist, ist dies nicht gerade ein dauerhafter Zustand.
Gerade eben ist der Rechner wieder einmal beim Versuch die Internetverbindung aufzubauen "hängen geblieben". Auf den ersten Blick zeigte sich bereits dass mit dem Rechner etwas nicht stimmt: die Tastatur-LEDs NumLock+ShiftLock blinkten in schönen Rhytmus. Nachdem ein Monitor herbeigeschafft war konnte ich zumindest erkennen dass der Rechner komplett gelockt ist. Ein Reboot später konnte ich zumindest die LogEinträge mir sichern sodass erkenntlich wird, was da überhaupt fehlgeschlagen ist.

Wie gesagt die installierten Pakete habe ich noch nicht mit denen vom SuSE-FTP-Server aktualisiert. Hier dann auch gleich meine Frage, ob es sich hier um einen Fehler im Kernel handelt (dann würde es ja ausreichen das neue Kernel-RPM vom SuSE-FTP einzuspielen) oder ob der Fehler im PPP-Daemon liegt.

Die Logeinträge (/var/log/messages)
Dec 24 21:47:06 router kernel: PPP: not interface or channel??
Dec 24 21:47:06 router pppd[4432]: ioctl(PPPIOCSNPMODE, 33, 0): Invalid argument (22)
lassen mich vermuten dass der PPP-Daemon oder das PPP-Kernelmodul der Schuldige ist
währendessen
Dec 24 21:47:06 router kernel: Unable to handle kernel NULL pointer dereference at virtual address 0000000a
IMHO mehr auf eine Exception im Kernel hinweist.

Irgendwelche Vorschläge ?
