Ieri in ufficio è arrivata una scheda Vodafone Mobile connect Card UMTS/GPRS da testare. Ora la scheda, come previsto contiene un CD per Windows ™ e viene data compatibile sono per sistemi operativi Microsoft, ma io volevo vedere come funziona con GNU/Linux. Ho visto sul web che alcuni ce l’avevano fatta ma anche che con questo nome Vodafone commercializza schede diverse.

La scheda viene riconoscita come un hub USB con tre periferiche USB seriali per cui è necessario usare il modulo usbserial

Di seguito sono descritti tutte le configurazioni che ho fatto io (ovviamente tutto va fatto da root)

modprobe usbserial vendor=0xaf0 product=0x5000

Ho notato che questo comando è meglio darlo prima di inserire la scheda altrimenti udev non crea

/dev/ttyUSB0 /dev/ttyUSB1 /dev/ttyUSB3

Questo è quello che appare in syslog quando inserisco la scheda:

A questo punto la configurazione del ppp. Il primo file /etc/ppp/peers/umts_vodafone:

/dev/ttyUSB0
460800
crtscts
lock
modem
noauth
defaultroute
connect "/usr/sbin/chat -v -f /etc/chatscripts/umts_vodafone"
noipdefault

remotename umts_vodafone
ipparam umts_vodafone
novj
ipcp-accept-remote
ipcp-accept-local
#lcp-echo-interval 0
#lcp-echo-failure 0

Ho lasciato le ultime due cose commentate perché nella configurazione del GPRS che uso con il cellulare Nokia 6310i le avevo dovute mettere pena la caduta della connessione.

Il secondo file /etc/chatscripts/umts_vodafone

In ultimo: /etc/ppp/resolv/umts_vodafone

nameserver 194.185.97.134

Giusto per la cronaca ho dovuto mettere il DNS a mano perchè ho avuto problemi con il ppp. Boh. Vi lascio un pezzo del log della connessione giusto per ulteriore aiuto.
