[Tech] LT Win modem e PPP

Gio 2 Nov 2000 09:30:52 CET

Ciao a tutti e scusate se vi scasso ancora riguardo al mio nuovo PC, ma la 
spalla lussata mi costringe a stare a casa e a scrivere con la sola mano sx.

Sopra ho installato la RH 7 e il modulo del kernel "ltmodem", visto che ho 
un winmodem interno PCI. Ho seguito tutti i passi del relativo HOWTO e il 
modem adesso mi risponde, anche se, dopo che alzo il portante una volta, mi 
locka la risorsa e non so + come riottenerla (mi tocca riavviare!!!).

Il problema che mi si presenta riguarda cmq il PPP, in quanto non mi parte 
(ho provato con diversi configuratori per le connessioni, ma il risultato è 
il solito) o meglio mi "muore inaspettatamente".

Ecco il report:

WvDial: Internet dialer version 1.41

PPP was killed! (signal = 11)
Disconnecting at Thu Nov  2 09:05:31 2000
Auto Reconnect will be attempted in 5 seconds
pppd error!  Look for an explanation in /var/log/messages.

Ovviamente, per il motivo che vi dicevo sopra, l'autoreconnect manco ci 
riprova ...

E questo il contenuto interessato del "messages":

Che ne dite? Cosa mi suggerite di fare? (cambiare modem a parte)

Spero cmq di fare parte lo stesso della cena di venerdì ... al limite 
qlcuno di voi mi imboccherà! (Marco?) ;-)

Grazie a tutti e ciao
