instalación y configuración

instalamos libusb-dev

hacemos make install en el directorio de usb-modemswitch y en el de usb-modemswitch-data
copiamos usb-modemswitch.conf a etc (con guion medio - y no guión bajo _ )

los hemos descargado de aquí:
http://www.draisberghof.de/usb_modeswitch/

configuración dispositivo usb

el comando lsusb no suelta:

Bus 002 Device 006: ID 12d1:1464 Huawei Technologies Co., Ltd.

con los datos del ID, lanzamos el comando siguiente:

usb_modeswitch -v 0x12d1 -p 0x1464 -M 55534243123456780000000000000011060000000000000000000000000000

(atención con el parametro -v y el -p que puede variar según el modelo)

cargar modulo

modprobe usbserial vendor=0x12d1 product=0x1464

comprobamos los dispotivos ttyUSB con ls /dev/ttyUSB* que debe darnos:

/dev/ttyUSB0 /dev/ttyUSB1 /dev/ttyUSB2 /dev/ttyUSB3

en alguna ocasión el dispositivo 0 se desconecta (documentar logs)
si el USB0 se cae. volvemos a intentarlo con:

rmmod option
rmmod usbserial
modprobe usbserial vendor=0x12d1 product=0x1464

y volvemos a comprobar que el ttyUSB0 no se desvanece ahora.

ya estamos listos para usar gnome-ppp para conectar.

conectar usando gnome-ppp

primero le damos permisos a pppd con:

chmod +s /usr/sbin/pppd

liego, le quitamos el PIN request a la tarjeta SIM

por útlimo arrancamos gnome-ppp y lo configuramos con esto:



y en las opciones marcamos modo estúpido.

ya podemos darle a conectar.

luego puede que falle el dns asignado y los nombres no resuelvan
así que ponemos en resolv.conf nuestros dns preferidos.



frst chmod +s /usr/sbin/pppd

remove pin request of sim

then configure gnome-pppd using:

1.- kernel modules

pcmcia
usb
ppp

2.- assign hardware as serial device

modprobe usbserial vendor=0xaf0 product=0x5000
ln -sf /dev/ttyUSB0 /dev/modem

3.- setting the network and pin

using minicom:

at_opsys=3,2 (UMTS, and if not available GPRS)
at+cpin="xxxx"

after 20-30 seconds, the card blink with the blue LED only. it means that you are registerd to the network. SIM accepted.

4.- setting the ppp

apt-get install ppp pppconfig
create default conection scripts with pppconfig called "3g" (f.e)

edit them:


noauth
connect "/usr/sbin/chat -v -f /etc/chatscripts/3g"
debug
lock
modem
/dev/modem
460800
replacedefaultroute
defaultroute
noipdefault
user "anything"
password "anything"
usepeerdns
novj
nobsdcomp

5.- connect

pon 3g

6.- disconnect

poff 3g

7.- automating the process

7.1.- once created the first time /dev/modem we can make a script containing:


(script header here)
modprobe usbserial vendor=0xaf0 product=0x5000
pon 3g

7.2.- add network and pin commands to custom chat script


ABORT BUSY ABORT 'NO CARRIER' ABORT ERROR REPORT CONNECT
TIMEOUT 10
'' ATZ
OK at_opsys=3,2
OK at+cpin="xxxx"
OK \d\d\d\d\d\d\d\d\d\d\d\d\d\d\dAT+CGDCONT=1,"IP","airtelnet.es"
TIMEOUT 60
OK-AT-OK "ATDT*99***1#"
CONNECT \d\c

(the \d character is a Delay for two seconds before AT command. it needs that time to register to the network)

7.3.- connect with

./3g.sh

7.4.- disconnect with

poff vodafone

7.5.- this chat script has a problem. when you send the ping command once you can not send it again. you'll receive an error. so it's efective only in certain circumstances. to resolve this you can have 2 differents scripts. one for the first time connection and the original ones (4.-) for the nexts.
