4.21 UMTS - Internet Connection Via UMTS

Connecting a fli4l to the Internet via UMTS. For proper operation other packages may be needed.

4.21.1 Configuration

OPT_UMTS

Default setting: OPT_UMTS='no'

'yes' activates the package.

UMTS_DEBUG

Default setting: UMTS_DEBUG='no'

If pppd should output additional debug information set UMTS_DEBUG to 'yes'. In this case pppd will write additional informations to the syslog interface.

IMPORTANT: To see this messages via syslogd OPT_SYSLOGD has to be set to 'yes'.

UMTS_PIN

Default setting: UMTS_PIN='disabled'

Pin for the SIM card

Give a four digit number or the word 'disabled'

UMTS_DIALOUT

Default setting: UMTS_DIALOUT='*99***1#'

Dialing parameters for the connection

UMTS_GPRS_UMTS

Default setting: UMTS_GPRS_UMTS='both'

Which transfer mode should be used

Possible values (both, gprs, umts)

UMTS_APN

Default setting: UMTS_APN='web.vodafone.de'

UMTS_USER

Default setting: UMTS_USER='anonymer'

UMTS_PASSWD

Default setting: UMTS_PASSWD='surfer'

Specify data needed for dial-in.

Set username and password for the provider used. UMTS_USER is the username, UMTS_PASSWD the password.

Name of the APN (Acess Provider Node) for some german providers

Dial-in data of some german providers



Provider APN Username Password
T-Mobile internet.t-mobile arbitrary arbitrary
Vodafone web.vodafone.de arbitrary arbitrary
E-Plus internet.eplus.de eplus gprs
O2 (Vertragskunden) internet arbitrary arbitrary
O2 (Prepaid-Kunden) pinternet.interkom.de arbitrary arbitrary
Alice internet.partner1 arbitrary arbitrary


UMTS_NAME

Default setting: UMTS_NAME='UMTS'

Set a name for the circuit here - maximum 15 chars. It will be shown in the imon-client imonc. Blanks are not allowed.

UMTS_HUP_TIMEOUT

Default setting: UMTS_TIMEOUT='600'

Specify a hangup time in seconds here if no traffic is detected over the UMTS connection. A timeout '0' is equal to no timeout.

UMTS_TIMES

Default setting: UMTS_TIMES='Mo-Su:00-24:0.0:Y'

Times mentioned here determine when the circuit becomes active and at what costs. This allows to use different circuits and default routes at different times (Least-Cost-Routing). The daemon imond will control routing.

UMTS_CHARGEINT

Default setting: UMTS_CHARGEINT='60'

Charge-Interval: Timespan in seconds, that will be used for calculating online costs.

UMTS_USEPEERDNS

Default setting: UMTS_USEPEERDNS='yes'

Use the provider's DNS server or not.

UMTS_FILTER

Default setting: UMTS_FILTER='yes'

fli4l automatically hangs up if no traffic is going over the ppp0 interface in the hangup timeout time. Unfortunately also data transfers from outside count as relevant traffic i.e. P2P-clients like eDonkey. Since you will be nearly permanently contacted from outside nowadays it may happen that fli4l never hangs up an UMTS connection.

Option UMTS_FILTER is helping here. If set to 'yes' only traffic generated by your own machine is monitored and external traffic will be ignored completely. Since incoming traffic normally leads to a reaction from the router or the machines behind it (i.e. denying or dropping the packets) some additional outgoing packets will be ignored too.

UMTS_ADAPTER

(optional)

Specify here if the hardware is a PCMCIA card, an USB adapter or a phone connected via an USB cable.

If omitting this variable only the files necessary for an USB adapter will be copied.

Possible values: (pcmcia,usbstick,usbphone)

All variables that follow are optional and only needed if the automatic detection fails.

UMTS_IDVENDOR

(optional) UMTS_IDVENDOR='xxxx'

Vendor ID after plugging/starting the adapter

UMTS_IDDEVICE

(optional) UMTS_IDDEVICE='xxxx'

Product ID after plugging/starting the adapter

Specifying the following two parameters is only needed if the ID changes after initialisation

UMTS_IDVENDOR2

(optional) UMTS_IDVENDOR2='xxxx'

Vendor ID after initialisation of the adapter

UMTS_IDDEVICE2

(optional) UMTS_IDDEVICE2='xxxx'

Product ID after initialisation of the adapter

UMTS_DRV

(optional) UMTS_DRV='xxxx'

Driver for the adapter, if omitted 'usbserial' is used

UMTS_SWITCH

(optional) UMTS_SWITCH='-v 0x0af0 -p 0x6971 -M 555...000 -s 10'

Parameters for usb-modeswitch initialisation of the modem (see Website usb-modeswitch). With a few exceptions all modems mentioned on the website should be recognized automatically.

UMTS_DEV

(optional)

In case of problems the data interface for pppd can be set here. The most usual for adapters are:

	ttyUSB0 for usbstick
	ttyS2   for pcmcia
	ttyACM0 for usbphone

UMTS_CTRL

(optional)

Some adapter have more interfaces for modem control. If only one is existig status informations can only be read in 'Offline' state. For Option Fusion UMTS Quad the interface is i.e. ttyUSB2.
