Requirements

This doc is tested on Alpine-2.1.3.

You will need a HSDPA USB-modem.
Use 'dmesg | less' to figure out which /dev/ttyUSB? it uses (you'll need to edit the configuration shown below to reflect the correct port number).

Install packages

Install the required packages

apk add ppp

Load modules

Now let's load the driver (using the values you just discovered) and configure Alpine to load it automatically at boot-up.

modprobe ppp_generic echo "ppp_generic" >> /etc/modules-load.d/ppp.conf

Config files

/etc/ppp/peers/E220

(The filename 'E220' can be changed, but you will need to remember it when running pon/poff command)

debug

/etc/ppp/chat-E220-pin

(The filename 'chat-E220-pin' can be changed, but you will need modify the config file shown above to reflect your decision)

ABORT "BUSY"
ABORT "ERROR"
ABORT "NO CARRIER"
REPORT "CONNECT"
TIMEOUT "10"

OK "AT+CPIN={PIN}"
OK AT+CGDCONT=1,"ip","{APN}"

OK "ATE1"
TIMEOUT "60"
"" "ATD*99***1#"
CONNECT \c

/etc/ppp/chat-E220-nopin

(The filename 'chat-E220-nopin' can be changed, but you will need modify the config file shown above to reflect your decision)

TIMEOUT "60"
"" "ATD*99***1#"
CONNECT \c
Note: Replace {PIN} with the "PIN" of your card (typically a 4 digit code)
Note: Replace {APN} with the "Access Point Name" of the service you use (e.g. "web.omnitel.it"). If you don't know the Internet APN, ask your service provider

Routes

Create a default gw route to your 'ppp0' device.

ip route add default dev ppp0

DNS

Figure out what DNS-servers your provider has.

egrep -i 'pppd.*dns' /var/log/messages

This might give you some useful information.
Search for a IP-address that might be your providers DNS-server and add this IP-address into '/etc/resolv.conf'.

echo "nameserver {DNS-server-IP-address}" > /etc/resolv.conf

Start/Stop

Start connection

pon E220

Stop connection

poff E220

If something goes wrong...

Check if process is running

pidof pppd

Logfile might give you a clue on what went wrong

egrep "pppd|chat" /var/log/messages

Check nic information

ifconfig ppp0

pppd has a statusinformation function that could come in handy

pppstats
